For context, during the quest they were worried that sending a signal into deep space could be dangerous. Columbina said she could use her power to shield the message even after it left the false sky.

The false sky is potentially the size of a star system, mind you. She also said she could use her power to monitor the nearby area outside the false sky for any danger.

While she admits she has limits, she also says she can keep the message going far enough that anyone who discovers it wouldn’t be able to trace it back to the false sky and by virtue Teyvat.

I also don’t know where the idea that the Light Realm was limited to Teyvat came from.

Nibelung used the power of the Light Realm to create Teyvat’s sun and moon, implying that the Light Realm is not limited to Teyvat and can create objects and place them thousands of miles away from the world itself.

During Version 6, Columbina was even prepared to live on the Frost Moon, which was outside the false sky.

Nibelung left Teyvat to investigate the Abyss. Unless you believe he manually flew through the universe at massively faster-than-light

speeds, he should have retained some method of interstellar travel through keeping his powers.

In the same Moon quest, it is stated that one of the researchers on the moon used a spaceship to travel to the coordinates where the message originated,

which was light-years away. However, they would not have enough fuel to return.

Correct me if I’m wrong, but isn’t all dragon technology powered by the Light Realm? That would mean a ship powered by the Light Realm could leave Teyvat and travel multiple light-years away.

In fact, let me add another range upscale.

According to the new quest, the moon is thousands of miles away from Teyvat.

I personally assume the false sky is the size of a star system or larger.

If that’s true, then the Heavenly Principles used their power to fling a moon-sized object from Teyvat to a location outside the false sky, aka beyond the boundaries of an entire star system.

According to the quest, the Frost Moon, despite being outside Teyvat, was completely uncorrupted by the Abyss.

Columbina theorizes that this is either because the Abyss was not paying attention or because the Heavenly Principles did something to protect it.

From a lore perspective, the latter seems more likely because the game states that the Abyss is always watching Teyvat.

There is also a belief, based on some Version 6.7 text, that the Heavenly Principles used their authority to alter the logic of the entire universe in order to hide Teyvat/the false sky and its surrounding areas.

The fact that the Frost Moon remained completely untouched by the Abyss despite being outside the false sky may provide more evidence for that interpretation.

The Genshin Universe

Its Size and Age:

The “Wheel of Fortune” mentions:

· “In 14 billion ‘years’ of darkness, it is the sum of all that is destined to happen and all that never will. Partings, encounters, and partings once more; birth, destruction, and birth yet again.”

· “In the darkness of 93 billion ‘years’ of light, all existence holds meaning unknown to any—without which this universe would seem too solitary.”

I assume these numbers represent the actual size and age of the universe, as they are too specific to be merely symbolic, although this is mainly speculation, and I’m not entirely sure.

But more concretely, here is evidence that it is billions of years old:

HEAVENSENT FRAGRANCE: Over billions of years, the fires of civilization lit up the endless stars, and ships wove through countless gates of stars.

State of the Universe:

The universe outside Teyvat is dying. This seems to be due to its fate being severed.

From HEAVENSENT FRAGRANCE:

That is, until the fate of the cosmos was severed thread by thread, and giants and dwarfs alike met the same end.

At first, it was no more than a mass hysteria, or the fading of a dream.

Then, in the silence of the night, an entire civilization was erased.

Next, extinguished dwarf stars streaked across the firmament like tears, and the embers of burned-out suns warped the very fabric of space.

It was only when entire galaxies evaporated into a void deeper than darkness that people finally came to realize the scale of the catastrophe.

· From The Little Witch and the Undying Flame, Volume 6:

· “The entire cosmos is going to die soon. Things peaked not long ago and are about to go south very fast.”

· “Many stars across the cosmos have gone out. I do not know how much time is left,” Octavia said, “so I wanted to come back to see you.”

· Durin’s Weapon Lore:

· “You must know that in a universe approaching its end, every star that has not yet been extinguished is precious…”

· “I never imagined that in a star region long deemed a dark domain, there still existed a living world.”

· The Sword of Descension:

· “But to draw steel against the law of the universe that ‘all who exist must one day perish’… surely it must have seemed the height of folly.”

· “But really, when one is faced with such a final fate, when up against the star-devouring darkness…”

· The Wings of Descension:

· “But when you face a force enough to destroy one, or even two worlds…”

· “When you face a boundless darkness, or an all-consuming radiance… But that was one world ago.”

· Finale of the Deep galleries:

· “I have seen the lightless end, tearing through star clusters like a spindle among silken threads.”

· “And yet, my kind, gentle king, will you still refuse to abandon your people? Forsake this world, fated for ruin, and journey with me beyond the stars.”

· “I have seen how the cold tide of chaos drowns out all songs, so that good and evil alike vanish into silence.”

· As Heaven and Earth Are Made Anew:

The true difficulty lay in finding a world with potential. Without that, destruction would catch up all too soon.

Note: The Abyss is likely the entity responsible for destroying the Genshin universe and what ultimately destroyed the world of the Traveler twins, the Primordial One, and Octavia. Though some civilizations, such as Skirk’s people, coexisted with it somewhat.

\---

Level of Advancement:

Some civilizations are advanced enough for interstellar travel. Examples include:

· The merchants and army who visited Skirk’s planet.

· The Traveler twins and their spaceships.

Some civilizations are also advanced enough to create “a weapon forged using the pooled resources of an entire star system.”

The Voyager could also make the SAMPO (Subatomic Assembling Mass-energy Patterning Orb), which can:

· Reconstruct matter at a subatomic scale.

· Transmute matter into stable energy to be released in an unknown form (the relevant description has been lost).

· The Traveler Ship: The fine details of the lithosphere, atmosphere, or biosphere ultimately mattered little. Reshaping terrain, adjusting the air, rebuilding an ecosystem — these were simple tasks for a pioneer vessel meant to bear the spark of civilization.

A star’s position, its distance, or its lifespan might pose a minor challenge, yet even those had solutions.

The most advanced civilization we have seen is the Voyager civilization, which was advanced enough for this:

HEAVENSENT FRAGRANCE:

The descendants of the ancients rose in defiance, and over the millions of years that followed, conquered time and space in turn.

To escape the annihilation that would one day engulf them all, those once-passionate pioneers sealed off the pathways that spanned the cosmos.

They retreated to the hollow heart of the star clusters, to the lightless edges of perception, as they clutched the last faint trace of hope.

The first people who had mastered leptons sent forth chroniclers toward the limits of baryonic matter, then in the hope of finding answers at the very last particle of existence.

Perhaps this so-called race that had transcended time was, in the end, nothing more than prisoners keeping vigil over a graveyard of stars.

Despite their knowledge that the darkness which erases existence itself was an inevitable end beyond all return,

the chroniclers, the last descendants of the ancients, remained faithful to their mission, engraving every star into memory.

⸻

Civilizations/Worlds in the Genshin Universe:

· Skirk’s People: They originated from an unnamed planet that was home to people with the ability to adapt to any type of environment or energy source.

At some point, a “merchant ship” from a neighboring planet investigated Skirk’s planet and deemed the inhabitants a “potential threat” due to their special adaptation ability. It is unknown what happened to the planet after Skirk escaped with the help of Surtalogi.

The chroniclers: the last descendants of the ancients, remained faithful to their mission, engraving every star into memory.
And this voyager, newly awakened from the void, was but one among those countless chroniclers.

· The Travelers’ Original Planet: “Once, (she/he) had been a scion of a lost, glorious kingdom, bearing the weight of an entire world.” This planet fell to destruction because of a “star-devouring darkness/abyss,” starting their travels between various worlds in a spaceship.

· Octavia’s Original Planet: Octavia is a member of the Hexenzirkel, where she goes by the codename “O.” Little is known about Octavia other than her self-insert character in The Little Witch and the Undying Fire.

She is a good friend of the “legendary old witch” (likely Andersdotter), who has seen many worlds and told many tales about the “sky beyond the sky.”

Her home was destroyed at some point in the past, but she lacked the courage to fight back and instead took up a life of eternal wandering.

· The Primordial One’s Original World / The Original World of Humanity: “For this was the new world it had chosen for the children of humanity, and by its design both earth and sky would be remade anew.”

Andromeda Empire: This is because the author’s portrayal of a certain princess from a galactic empire caused significant resentment from the real princess who inspired the character.

\---

Worlds Octavia visited:

189th world:

Cloud Edge's Glory:

When Octavia's journey reached the 1,896th planet, the local civilization was still in the classical era of city-states featuring the use of bronze tools.

The city-states were constantly at war with each other and had long been mired in conflict.

The arrival of enemies from the Abyss further exacerbated the distrust and division among the city-states.

To end this chaos, they decided to hold sacred tournaments during ceremonies honoring their heroes, with the one who obtained the most crowns becoming the leader of all city-states,

responsible for quelling internal strife and repelling external enemies. Upholding the tradition of respecting all mighty warriors,

Octavia, who had descended upon this world, was invited by the city-states to participate in this tournament.

As a witch capable of traveling among the stars, she won every competition she entered without question.

Her image, clad in the Cloud Edge's Glory Set, was immortalized in a statue that still stands in the hall of sacred tournaments, and also in Octavia's memory.

An unknown world:

After witnessing many prosperous civilizations, Octavia unexpectedly arrived at a planet in its "Primitive Age."

Though the people here had not yet developed an advanced civilization, they possessed customs of communicating with the wilderness and hearts filled with the spirit to challenge fierce beasts and disasters.

Some natives saw Octavia as a dangerous outsider, greeting her with spears and flying stones, though she admired their courage. Another group politely invited her to feast, asking her about the mysteries of the stars in clumsy but sincere language. Having no interest in playing the role of a god, Octavia simply documented their distinctive attire, shared a few fairy tales with them, and left their natural evolution untouched.

1,217th world:

Among the endless reaches of the universe, some worlds hum with extraordinary mystical powers, while others remain untouched and ordinary.

The 1,217th planet visited by Octavia was one such unremarkable world — a place where humans were born without the gift of flight. However, it was precisely this invisible restraint that kindled their boundless desire to soar.

Their flying machines were crude and offered scant protection, but still, they pursued the skies with unwavering resolve.

As they would say, "Once you've experienced flight, your eyes will always turn skyward. Having touched its vastness, you'll carry a lasting longing for that freedom."

While observing the 1,217th planet, Octavia discovered that due to the lack of extraordinary powers and space technology, its inhabitants' understanding of the universe and the microscopic world was based largely on limited observational data and mathematical deductions.

Nevertheless, their insights, though abstract, were nothing short of profound, and the most accomplished among their astronomers were capable of predicting cosmic anomalies through mathematical calculations.

However, as an extraterrestrial observer, Octavia provided no path forward. Just as the precept, passed down through generations of sages clad in star-patterned robes, goes: "Truth itself is easy to understand; the key lies in the process of discovery."

In her pursuit of starkly different scenery, Octavia would sometimes shift her activity to the night to circumvent the crowds.

This allowed her to encounter a mysterious profession on the 1,217th planet: the Owl Envoy.

The Owl Envoys held an enigmatic occupation and used the image of a small, agile owl as their emblem.

They operated only during dusk and night, traversing all kinds of rugged terrain with ease thanks to their extraordinary agility and silent movements, facing potential dangers with formidable strength. In a world without supernatural elements or advanced technology, their aura of mystery and power led Octavia to associate them with the messengers of Natlan.

66th world:

On the 66th planet, a world perpetually shrouded in a purple-black haze of "Misfortune," dwells an active group known as "Auspimancers."

They are far more than geomancers in any traditional sense — they are strategists who provide their clients with tactical assistance and help them navigate through crises.

Renowned for their ability to steer through peril toward stability, it is widely believed that they are able to repel "Misfortune" itself by reading the hidden energies of the land.

It was the leader of these auspimancers, the most observant person on the planet, who first discovered that Octavia came from interstellar space.

Thanks to her mediation and guidance, Octavia was able to establish contact with the local inhabitants without any friction or conflict whatsoever.

Even for the seasoned traveler Octavia, the 66th planet stood out as extraordinary. Perhaps a form of "convergent evolution" had shaped its civilization, for some of its customs echoed those of Liyue in Teyvat.

At the turn of the year, both cultures adorned themselves with metallic coins symbolizing wealth, a gesture meant to usher in prosperity.

Yet the planet's New Year was far longer than Liyue's — sometimes lasting an entire stellar year.

Its length was measured by the "Nian beast's presence," and only when this presence peaked could the year be considered complete.

Octavia noted that the so-called "Nian" beast resembled certain abyssal creatures. The circular coins with square holes, employed as decorations,

seemed to function much like Liyue's Adepti Sigils, capable of dispelling the ominous force locals called "bad luck."

Recognizing the special significance of this attire, Octavia deliberately added it to her collection of firsthand experiences.

Legends tell that when the violet-black shroud of misfortune lifts, the skies of the 66th world change in a heartbeat, dark clouds giving way to a brilliant dawn.

In that fleeting moment, scarlet clouds and freely flowing skies come to embody hope and good fortune, their forms echoed throughout local dress and ornamentation. Wary of drawing suspicion as an outsider, Octavia embraced these symbols when designing an outfit meant to follow local custom.

666th world:

As the decisive clash erupted on the 666th planet, the kingdom's twin "Lazurite Swords" plunged into the heart of the fell dragon's territory, nearly severing its lifeline before falling to an inexhaustible swarm.

Just as all hope seemed lost, their lieutenants arrived with Octavia's backing. Tearing through the last obstacle,

they decapitated the fell dragon and returned the letters their commanders had penned, a sign that the day of sacrifice was over.

In the wake of their victory, the twin "Lazurite Swords" stepped down from their roles, bequeathing their legacy to their two lieutenants.

As the new generals took command, they committed themselves to sweeping away the last of the foe. Elements of the fell dragon's form were dismantled and forged into ornaments for their new armor,

serving as an unparalleled deterrent against the monsters that remained.

Octavia would always remember the heroic sight of the two new generals — including the silhouette of their slightly trembling hands as they signed the papers to pay her spaceship's damages in full.

For some unknown reason, the 666th planet harbors a deadly evil power that has caused monsters to ravage the land unchecked, and for decades, the "Kingdom's" troops have struggled to hold the line against these monsters.

However, a certain unit led by two field-grade officers has succeeded in penetrating the enemy line on several occasions.

Drawing on discoveries from a long-lost civilization made by two historians, and on calculations from the visitor Octavia, the two commanders were able to pinpoint the monsters' lair — the very same monsters that had caused the downing of Octavia's ship, it turns out.

67th World

Landscape & Environment

“On the 67th planet Octavia visited, advanced technology has brought evergreen crops that thrive year-round, greatly diminishing the effects of withering and decay on agriculture. Yet naturalism hasn’t completely yielded to technology. Unmodified ordinary plants—that grow, mature, and fade with the seasons—are still widely preserved as a vital part of the world’s original landscape.” (Autumn Veins description)

Three seasonal celebrations:

· Autumn/Harvest Season: “The autumn season of maturity and harvest, like on many similar worlds, is celebrated and cherished. Gold and orange, as primary colors, symbolize fruits and often evoke a sense of harvest, while azure represents vitality.” (Autumn Veins)

· Spring Festival: “Like many civilizations across the universe, they had a clear concept of ‘seasons.’

Though expressed in different languages, the season when crops begin to sprout and grow was always given imagery similar to ‘spring.’ The people here likewise held lively celebrations before the arrival of spring to express their good wishes for the future.” (Prelude to Spring)

· Winter Gathering: “When it comes to winter festivals, there’s no celebration without a crackling hearth, a hearty feast, beautifully wrapped gifts, and—most importantly—joyful songs shared in reunion!” (Winter’s Warmth)

Memorable Encounter

“On that winter day, she arrived at a small, unfamiliar town and hesitantly asked for a place to stay. A kind family welcomed her with warm hospitality. The humble couple served her a generous meal, while their lively children performed melodious songs for her.” (Winter’s Warmth)

Octavia: “Before leaving, she gifted them the sweetest red fruit she had found on this planet as a token of gratitude.”

\---

93rd World – “The Academy Planet”

“Though they possessed the ability to modify their entire planet and merge it into a giant academic collective…” (Astral Beacon)

“…the civilization to which the 93rd world—the Academy Planet—belonged still placed strong emphasis on basic geology and mapping.” (Astral Beacon)

“Of all the worlds Octavia visited, the 93rd was the most peaceful.” (Dawn’s Visionary)

“This was a pure Academy Planet with an impeccable scholastic atmosphere and living conditions, capable of constantly producing talent with wisdom, skill, and good conduct in equal measure for the civilizations under its purview.” (Dawn’s Visionary)

The phrase “for the civilizations under its purview” suggests the Academy Planet might serve as an educational hub for multiple civilizations.

Cultural Practices

Graduation ceremonies: “This Dawn’s Visionary set is, in turn, based on the most luxurious of graduation gowns. It reminds Octavia of the time she attended three graduation ceremonies in one day back in her younger years…” (Dawn’s Visionary)

Octavia Encounter

“A young man and woman saw through her. As it turned out, they had long yearned for both the skies and adventure, and while traveling through the clouds in a hot air balloon, they witnessed Octavia as she landed.” (Painted Skies)

“They longed for a life like hers, and thus agreed to keep her secret. Octavia, for her part, saw a certain romanticism in their attitude, along with similarities to people she once knew. Thus, she promised to take them on an interstellar graduation trip once they had completed their key studies…” (Painted Skies)

This reveals that students have awareness of interstellar travel.

“It reminds Octavia of the time she attended three graduation ceremonies in one day back in her younger years, along with classmates whose faces had grown less distinct in her mind over time…” (Dawn’s Visionary)

118th World – “The Forest of Steel”

Landscape & Environment

Complete urbanization: “After seven days of travel, Octavia wrote the following comment for the 118th world she discovered by chance: ‘The Forest of Steel.’ This was no exaggeration—cities sprawl across this world’s continents, weaving a seamless ‘civilized existence’ using steel, concrete, and strict regulations.” (Offbeat District)

Social Dynamics

“Within a broader system of ‘civilized life’ that placed immense value on work, the people of the 118th planet often suffered from health issues linked to sedentary lifestyles and excessive overtime.” (Orange Passion)

Octavia’s personal experience: “Octavia was not here long before she had received over 100 recruitment messages from professional headhunters, alongside double that number of health supplement ads.” (Orange Passion)

Counter-Culture Movements

Artistic rebellion: “Yet this order has also given rise to artistic groups who stand against the rules, the rising stars of which use this ‘Offbeat District’ to showcase their striving for freedom…” (Offbeat District)

Music performance: “Octavia, on a whim, visited a popular music performance venue. There, she mingled with the enthusiastic audience and enjoyed a vivid array of performances.

A young but passionate duo left a deep impression on her. It was said that once they made their name in the two-thousand-seat venue, they would step onto even grander stages, aiming to hold concerts in arenas with tens of thousands of spectators.” (Radiant Melody)

Sports & Competition

“Octavia encountered fierce fighting tournaments taking place within the steel forests of the 118th world. The trophy the contestants fought for would add an important feather to their city’s cap.” (Fervent Fighter)

Octavia’s Reflection

“Years later, when Octavia came across the costume records, she couldn’t help but wonder if they had reached their goal.” (Radiant Melody)

273rd World

Landscape & Environment

“Situated on the edge of its stellar system with insufficient sunlight, its land remains frozen in ice and snow all year round…” (White Flash)

“When the planet reached its farthest orbital point, the temperature dropped by another thirty percent, approaching the lowest point of particle kinetic energy.” (Frosty Plume)

The phrase “approaching the lowest point of particle kinetic energy” indicates temperatures nearing absolute zero.

Geographic features: “In top-tier competitions, athletes sprint down from mountain peaks that pierce through the clouds with slopes almost vertical…” (White Flash)

Civilization Level & Technology

“The severe winter was one of their greatest adversaries, but it also witnessed their complete establishment on every star in the stellar system.” (Frosty Plume)

“For this reason, people would hold elegant celebrations on the coldest snow night, and the attire of the two hosts was thus etched in Octavia’s memory…” (Frosty Plume)

Skiing culture:

“The most popular sport here is extreme skiing. In top-tier competitions, athletes sprint down from mountain peaks that pierce through the clouds with slopes almost vertical, diving at speeds faster than birds can follow, leaving only trails of pure white…” (White Flash)

“Octavia purchased this ski suit—youthful in style yet exceptional in performance—and attempted a dive that broke the local sound barrier.” (White Flash)

“When the planet reached its farthest orbital point, the temperature dropped by another thirty percent, approaching the lowest point of particle kinetic energy. Even her coat, which could withstand gunfire and molten iron, could hardly endure this ordeal.

Just then, a classical and elegant manor appeared before her, where two young hosts warmly graciously invited her inside and welcomed her to an elegant ball.” (Frosty Plume)

Symbolic Significance

“As it turned out, this place was regarded as a milestone for the civilization’s triumph over harsh environments.” (Frosty Plume)

712th World – “The Paradise Planet.”

Landscape & Environment

“Every city in this world was a holiday haven with a unique theme.” (Scarlet Shade)

“Octavia served as a consultant on the 712th world she visited for 10 years.” (Fairyland Prom)

“While touring the 712th world, the Paradise Planet, Octavia encountered a phenomenon known as the ‘devaluation of happiness’: constant exposure to pleasure and entertainment gradually raises one’s threshold for happiness. As such, a suitable amount of tranquility is necessary for both guests and the planet itself.” (Mystic Forest)

Octavia’s Design Solutions

Color psychology framework: “…the most important of which was the influence of color on emotion. At that time, two brilliant artists stood up to present Octavia with a multitude of fantastical plans.” (Chromatic Artisan)

“What should the main visual style of a theme park that wanted to appear solemn, elegant, mysterious, and opulent all at once be?” (Steamwave Chronicles)

“Octavia’s answer contained many elements derived from Fontaine in Teyvat and from local historical ‘technical aesthetics,’ which proved incredibly popular.” (Steamwave Chronicles)

This shows:

· Octavia actively uses Teyvat as design inspiration for other worlds.

Themed Districts

Ninja City (Inazuma-inspired):

“Once employed as a consultant, she would tell the people tales of distant Teyvat, and the people of the Paradise Planet would make special modifications to their pre-existing ninja city based on the Inazuman stories she told…” (Scarlet Shade)

Fairytale Theme Park:

“By the time she parted ways with them, the fairytales she told the children had already become popular, with many novels, picture books, and film adaptations, as well as a theme park of just the right scale.” (Fairyland Prom)

Timeline:

· Octavia tells stories to children
· Stories become novels and picture books
· Film adaptations are produced
· A theme park is constructed
· All within 10 years

Mystic Forest (Sumeru-inspired):

“As such, Octavia designed a serene ‘forest’ with the rainforests of Sumeru in Teyvat in mind—a place where people can slowly relax through a leisurely journey of exploration.” (Mystic Forest)

Steamwave Chronicles (Fontaine-inspired):
“Octavia’s answer contained many elements derived from Fontaine in Teyvat and from local historical ‘technical aesthetics.’” (Steamwave Chronicles)

Direct referral:

“After Octavia was accidentally struck by a high-speed comet, she followed the recommendations of the residents of the 712th ‘Elysium Star’ and made several transfers before arriving at the 722nd planet, the ‘Sanctuary of Recovery.’” (Healing Heart)

“Octavia was also invited to the opening ceremony, where she personally chose the most suitable outfits for the young men and women playing the leading roles…” (Fairyland Prom)

722nd World – “The Sanctuary of Recovery”

Civilization Level & Technology

“Here, the civilization’s finest doctors and nurses can treat various common—and even peculiarly shaped and fundamentally different—forms of life.” (Healing Heart)

The phrase “peculiarly shaped and fundamentally different forms of life” indicates that the Genshin universe contains biological diversity.

Cultural Values

“For some highly advanced civilizations, medical care has become an extremely important industry.” (Healing Heart)

The phrasing “for some highly advanced civilizations” implies that not all advanced civilizations prioritize medical care equally.

Octavia’s Experience

“After Octavia was accidentally struck by a high-speed comet…” (Healing Heart)

Given her survival, this reveals she has extreme durability.

“Octavia experienced what she calls ‘retirement life’ here for a while. Her wounds soon healed, and she was cared for with kindness and patience by two young medical practitioners who left a deep impression on her.” (Healing Heart)

“Before departing, they even took a commemorative photo together…” (Healing Heart)

This indicates:

· Photography technology exists in the 722nd world

777th World – “The Magic Civilization”

Landscape & Environment

“A land of quietude and mystery, upon which all civilization was built on a foundation of standardized spellwork—where nothing can truly escape the grasp of ‘magic.’” (Phantom Night)

Atmospheric magic limitation:

“In this world—the 777th chronicled by Octavia—the magic that all things rely upon cannot seem to leave the atmosphere, thus binding the wizards, witches, and their wondrous creations to gravity’s well.” (Rose’s Lament)

External Threats

“Yet the threat from deep space continued to grow, and so the young scholars wearing the Rose’s Lament set undertook a bold experiment: imbuing magic into meteorite dust and doing all they could to send it back into orbit…” (Rose’s Lament)

The “threat from deep space” likely refers to:

· Abyssal encroachment

· Other potentially hostile civilizations

Cultural Practices

“Moonlight descends, candles flicker, and the night of revelry begins.” (Candlelit Revelry)

“During classes, they proved skilled at extracting the essentials from obscure esoterica. And in their daily lives—and especially at the festival known to later generations as the Candlelit

Revelry—they would be like carefree young men and women, joining the students in fun but moderate pranks, even leading them in begging for candies from other teachers.” (Candlelit Revelry)

Post-Catastrophe

“The 777th world that Octavia chronicled once fell briefly into chaos due to calamitous meteorite showers. Once the crisis had been properly handled and the relevant organizations had completed a set of perfect precautionary measures,

they then had ‘opera mages’—who used magic to create light effects, sounds, and visual tricks—take the stage, perform, and soothe the people.” (Sonic Ruins)

The Sonic Ruins group:

“The alternative opera group, Sonic Ruins, was a luminary leader amongst these mages…” (Sonic Ruins)

First encounter:

“The first friends Octavia made on the 777th world were two highly gifted and hospitable high-level professors of magic.” (Candlelit Revelry)

“During classes, they proved skilled at extracting the essentials from obscure esoterica.” (Candlelit Revelry)

Personal gift:

“Before Octavia left, the two designed a gown for their guest, one that they filled with sincere blessings…” (Candlelit Revelry)

Medical referral system:

“After Octavia was accidentally struck by a high-speed comet, she followed the recommendations of the residents of the 712th ‘Elysium Star’

and made several transfers before arriving at the 722nd planet, the ‘Sanctuary of Recovery.’” (Healing Heart)

“Made several transfers” indicates that no direct travel route exists between these worlds.

Teyvat is a planet located at the edge of a spiral arm. Currently, it is covered by a false sky meant to keep the Abyss out and make it more difficult to detect from the outside universe:

But now, it lay shrouded behind several impenetrable fields, its primordial flame stripped of the radiance it was meant to bear.

The Heavenly Principles set laws that outlanders—even some abyssal beings—must follow:

even invaders who seek to claim this world must obey its rules to some extent.

Unless the heavens split open and the earth’s defenses collapse, these star-born outsiders can do little more than linger at the world’s fringes,

whispering their madness into this realm; their attempts to seep inside amount to nothing.

The formless beast that soared through the starless void should never have required organs this world calls “wings.”

Those grotesque, profane appendages may have arisen to adapt to the laws beneath the moon, though Descenders may be immune to them to some extent—or perhaps entirely.

Races in the Genshin Universe:

· Skirk’s Race: Distinct from humans, as they have a fin on their back. They can also coexist with the Abyss to some extent. They are physically stronger than regular humans.

· The Voyager’s Race: A “scribe” whose mind travels the cosmos while her body rests in a distant celestial disk-construct. Her species are scribes who chart civilizations doomed to perish. She is not human—possibly an invertebrate or non-animal lifeform—as she refers to humans as “chordate animals.”

· Humans (or Humanoids): Many worlds have human-like societies, such as the worlds Octavia visited. However, I’m a bit confused about the difference between humans in Teyvat and humans in other worlds, as humans in Teyvat likely originate from the Primordial One’s original world and might be biologically different from people like Octavia or those in the worlds she visited.

· The Travelers’ Species: Humanoid. They have extremely long lifespans and are basically immortal. They can also survive and travel in space and don’t seem to need to eat or drink. I’m also not sure if the Traveler has to do things normal humans do, or if they just prefer to. I’m also unsure if everyone on the Travelers’ home planet was like this, or just the twins. For the twins themselves, I theorize they are some type of god, as gods exist outside of Teyvat. They could possibly have been born alongside their world, like Nibelung.

· The All-Devouring Narwhal’s Species: Unknown, but it is likely beyond conventional biology.

· The beings Surtalogi beat: “If it was a wicked beast, he ate its flesh. If it was a god or a machine, he absorbed its energy. If it was a warrior or mage, he played with his food — forcing them to use every trick in their book, then cutting them down once he tired of the charade.”

· The rat Skirk ate: “Though, I should mention I brought it here from another planet, since all life on yours is extinct.”

· The creatures Skirk encountered:

“During my journey through the stars, I came across a species with completely inverted sensory perception.

They’d use ice to warm themselves up, and cool down by the fire. They’d be sweating buckets inside a cold, dark cave, but shiver uncontrollably under the blazing sun. So different from all the other creatures around them, and yet they lived quite happily.

That’s the miracle of life — unfathomably complex, but at the same time so simple.”

\---

Universal Concepts

The Abyss

The Abyss is a cosmic phenomenon and is likely the force destroying the Genshin universe. It is not limited to Teyvat; it hates, destroys, and has consumed countless star systems and worlds.

Will

The concept of will is not limited to Teyvat.

“Not all that comes from beyond may be one that ‘descends.’ That title belongs only to wills that can rival an entire world. That is what I seek: the way to become such a will—one that can protect the world, sustain the world, destroy the world, and create the world.”

— Notes #1, The Narzissenkreuz Ordo

The Voyager—an outlander not from Teyvat—noticed Nibelung due to his strong will:

“It came from an unremarkable little world at the edge of the spiral arm—and from the primeval dragon that had been born alongside that world. Though death would one day bring an endless night, and the sun it gazed upon was but a fleeting ember, this will, bound though it was to its planetary crust, shone more brilliantly than all the civilizations the voyager had ever seen.”

— Deep Gallery’s Distant Pact

“Ambition should be something that transcends the world below and the starry sky above—something that shines in unison with fate itself.”

— Narzissenkreuz Sword Lore

“A sacred blade indwelt with great enough reason and will to create and destroy a universe—or a dream.”

The Traveler’s sibling even stated that she would need the might of an entire world to speak to the Heavenly Principles as an equal, which may be a description of what it means to be a Descender.

Fate

Another universal concept is fate. The reason the Abyss started destroying the universe is that its fate was severed, and the Abyss is all the fates that never came to be. Along with Surtalogi being bound by destiny, this suggests there is a separate universal fate from the one the Heavenly Principles made.

The Genshin Universe

Its Size and Age:

The “Wheel of Fortune” mentions:

· “In 14 billion ‘years’ of darkness, it is the sum of all that is destined to happen and all that never will. Partings, encounters, and partings once more; birth, destruction, and birth yet again.”

· “In the darkness of 93 billion ‘years’ of light, all existence holds meaning unknown to any—without which this universe would seem too solitary.”

I assume these numbers represent the actual size and age of the universe, as they are too specific to be merely symbolic, although this is mainly speculation, and I’m not entirely sure.

But more concretely, here is evidence that it is billions of years old:

HEAVENSENT FRAGRANCE: Over billions of years, the fires of civilization lit up the endless stars, and ships wove through countless gates of stars.

---

State of the Universe:

The universe outside Teyvat is dying. This seems to be due to its fate being severed.

From HEAVENSENT FRAGRANCE:

That is, until the fate of the cosmos was severed thread by thread, and giants and dwarfs alike met the same end.

At first, it was no more than a mass hysteria, or the fading of a dream.

Then, in the silence of the night, an entire civilization was erased.

Next, extinguished dwarf stars streaked across the firmament like tears, and the embers of burned-out suns warped the very fabric of space.

It was only when entire galaxies evaporated into a void deeper than darkness that people finally came to realize the scale of the catastrophe.

Despite their knowledge that the darkness which erases existence itself was an inevitable end beyond all return,

· From The Little Witch and the Undying Flame, Volume 6:

· “The entire cosmos is going to die soon. Things peaked not long ago and are about to go south very fast.”

· “Many stars across the cosmos have gone out. I do not know how much time is left,” Octavia said, “so I wanted to come back to see you.”

· Durin’s Weapon Lore:

· “You must know that in a universe approaching its end, every star that has not yet been extinguished is precious…”

· “I never imagined that in a star region long deemed a dark domain, there still existed a living world.”

· The Sword of Descension:

· “But to draw steel against the law of the universe that ‘all who exist must one day perish’… surely it must have seemed the height of folly.”

· “But really, when one is faced with such a final fate, when up against the star-devouring darkness…”

· The Wings of Descension:

· “But when you face a force enough to destroy one, or even two worlds…”

· “When you face a boundless darkness, or an all-consuming radiance… But that was one world ago.”

· Finale of the Deep galleries:

· “I have seen the lightless end, tearing through star clusters like a spindle among silken threads.”

· “And yet, my kind, gentle king, will you still refuse to abandon your people? Forsake this world, fated for ruin, and journey with me beyond the stars.”

· “I have seen how the cold tide of chaos drowns out all songs, so that good and evil alike vanish into silence.”

· As Heaven and Earth Are Made Anew:

The true difficulty lay in finding a world with potential. Without that, destruction would catch up all too soon.

Note: The Abyss is likely the entity responsible for destroying the Genshin universe and what ultimately destroyed the world of the Traveler twins, the Primordial One, and Octavia. Though some civilizations, such as Skirk’s people, coexisted with it somewhat.

---

Level of Advancement:

Some civilizations are advanced enough for interstellar travel. Examples include:

· The merchants and army who visited Skirk’s planet.

· The Traveler twins and their spaceships.

Some civilizations are also advanced enough to create “a weapon forged using the pooled resources of an entire star system.”

The Voyager could also make the SAMPO (Subatomic Assembling Mass-energy Patterning Orb), which can:

· Reconstruct matter at a subatomic scale.

· Transmute matter into stable energy to be released in an unknown form (the relevant description has been lost).

· The Traveler Ship: The fine details of the lithosphere, atmosphere, or biosphere ultimately mattered little. Reshaping terrain, adjusting the air, rebuilding an ecosystem — these were simple tasks for a pioneer vessel meant to bear the spark of civilization.

A star’s position, its distance, or its lifespan might pose a minor challenge, yet even those had solutions.

The most advanced civilization we have seen is the Voyager civilization, which was advanced enough for this:

HEAVENSENT FRAGRANCE:

The descendants of the ancients rose in defiance, and over the millions of years that followed, conquered time and space in turn.

To escape the annihilation that would one day engulf them all, those once-passionate pioneers sealed off the pathways that spanned the cosmos.

They retreated to the hollow heart of the star clusters, to the lightless edges of perception, as they clutched the last faint trace of hope.

The first people who had mastered leptons sent forth chroniclers toward the limits of baryonic matter, then in the hope of finding answers at the very last particle of existence.

Perhaps this so-called race that had transcended time was, in the end, nothing more than prisoners keeping vigil over a graveyard of stars.

Despite their knowledge that the darkness which erases existence itself was an inevitable end beyond all return,

the chroniclers, the last descendants of the ancients, remained faithful to their mission, engraving every star into memory.

⸻

Civilizations/Worlds in the Genshin Universe:

· Skirk’s People: They originated from an unnamed planet that was home to people with the ability to adapt to any type of environment or energy source.

At some point, a “merchant ship” from a neighboring planet investigated Skirk’s planet and deemed the inhabitants a “potential threat” due to their special adaptation ability. It is unknown what happened to the planet after Skirk escaped with the help of Surtalogi.

The chroniclers: the last descendants of the ancients, remained faithful to their mission, engraving every star into memory.
And this voyager, newly awakened from the void, was but one among those countless chroniclers.

· The Travelers’ Original Planet: “Once, (she/he) had been a scion of a lost, glorious kingdom, bearing the weight of an entire world.” This planet fell to destruction because of a “star-devouring darkness/abyss,” starting their travels between various worlds in a spaceship.

· Octavia’s Original Planet: Octavia is a member of the Hexenzirkel, where she goes by the codename “O.” Little is known about Octavia other than her self-insert character in The Little Witch and the Undying Fire.

She is a good friend of the “legendary old witch” (likely Andersdotter), who has seen many worlds and told many tales about the “sky beyond the sky.” Her home was destroyed at some point in the past, but she lacked the courage to fight back and instead took up a life of eternal wandering.

· The Primordial One’s Original World / The Original World of Humanity: “For this was the new world it had chosen for the children of humanity, and by its design both earth and sky would be remade anew.”

Andromeda Empire: This is because the author’s portrayal of a certain princess from a galactic empire caused significant resentment from the real princess who inspired the character.

Worlds Octavia visited:

189th world:

Cloud Edge's Glory:

When Octavia's journey reached the 1,896th planet, the local civilization was still in the classical era of city-states featuring the use of bronze tools.

The city-states were constantly at war with each other and had long been mired in conflict.

The arrival of enemies from the Abyss further exacerbated the distrust and division among the city-states.

To end this chaos, they decided to hold sacred tournaments during ceremonies honoring their heroes, with the one who obtained the most crowns becoming the leader of all city-states, responsible for quelling internal strife and repelling external enemies. Upholding the tradition of respecting all mighty warriors,

Octavia, who had descended upon this world, was invited by the city-states to participate in this tournament.

As a witch capable of traveling among the stars, she won every competition she entered without question.

Her image, clad in the Cloud Edge's Glory Set, was immortalized in a statue that still stands in the hall of sacred tournaments, and also in Octavia's memory.

An unknown world:

After witnessing many prosperous civilizations, Octavia unexpectedly arrived at a planet in its "Primitive Age."

Though the people here had not yet developed an advanced civilization, they possessed customs of communicating with the wilderness and hearts filled with the spirit to challenge fierce beasts and disasters.

Some natives saw Octavia as a dangerous outsider, greeting her with spears and flying stones, though she admired their courage. Another group politely invited her to feast, asking her about the mysteries of the stars in clumsy but sincere language. Having no interest in playing the role of a god, Octavia simply documented their distinctive attire, shared a few fairy tales with them, and left their natural evolution untouched.

1,217th world:

Among the endless reaches of the universe, some worlds hum with extraordinary mystical powers, while others remain untouched and ordinary.

The 1,217th planet visited by Octavia was one such unremarkable world — a place where humans were born without the gift of flight. However, it was precisely this invisible restraint that kindled their boundless desire to soar.

Their flying machines were crude and offered scant protection, but still, they pursued the skies with unwavering resolve.

As they would say, "Once you've experienced flight, your eyes will always turn skyward. Having touched its vastness, you'll carry a lasting longing for that freedom."

While observing the 1,217th planet, Octavia discovered that due to the lack of extraordinary powers and space technology, its inhabitants' understanding of the universe and the microscopic world was based largely on limited observational data and mathematical deductions.

Nevertheless, their insights, though abstract, were nothing short of profound, and the most accomplished among their astronomers were capable of predicting cosmic anomalies through mathematical calculations.

However, as an extraterrestrial observer, Octavia provided no path forward. Just as the precept, passed down through generations of sages clad in star-patterned robes, goes: "Truth itself is easy to understand; the key lies in the process of discovery."

In her pursuit of starkly different scenery, Octavia would sometimes shift her activity to the night to circumvent the crowds.

This allowed her to encounter a mysterious profession on the 1,217th planet: the Owl Envoy.

The Owl Envoys held an enigmatic occupation and used the image of a small, agile owl as their emblem.

They operated only during dusk and night, traversing all kinds of rugged terrain with ease thanks to their extraordinary agility and silent movements, facing potential dangers with formidable strength. In a world without supernatural elements or advanced technology, their aura of mystery and power led Octavia to associate them with the messengers of Natlan.

66th world:

On the 66th planet, a world perpetually shrouded in a purple-black haze of "Misfortune," dwells an active group known as "Auspimancers."

They are far more than geomancers in any traditional sense — they are strategists who provide their clients with tactical assistance and help them navigate through crises.

Renowned for their ability to steer through peril toward stability, it is widely believed that they are able to repel "Misfortune" itself by reading the hidden energies of the land.

It was the leader of these auspimancers, the most observant person on the planet, who first discovered that Octavia came from interstellar space.

Thanks to her mediation and guidance, Octavia was able to establish contact with the local inhabitants without any friction or conflict whatsoever.

Even for the seasoned traveler Octavia, the 66th planet stood out as extraordinary. Perhaps a form of "convergent evolution" had shaped its civilization, for some of its customs echoed those of Liyue in Teyvat.

At the turn of the year, both cultures adorned themselves with metallic coins symbolizing wealth, a gesture meant to usher in prosperity.

Yet the planet's New Year was far longer than Liyue's — sometimes lasting an entire stellar year.

Its length was measured by the "Nian beast's presence," and only when this presence peaked could the year be considered complete.

Octavia noted that the so-called "Nian" beast resembled certain abyssal creatures. The circular coins with square holes, employed as decorations,

seemed to function much like Liyue's Adepti Sigils, capable of dispelling the ominous force locals called "bad luck."

Recognizing the special significance of this attire, Octavia deliberately added it to her collection of firsthand experiences.

Legends tell that when the violet-black shroud of misfortune lifts, the skies of the 66th world change in a heartbeat, dark clouds giving way to a brilliant dawn.

In that fleeting moment, scarlet clouds and freely flowing skies come to embody hope and good fortune, their forms echoed throughout local dress and ornamentation. Wary of drawing suspicion as an outsider, Octavia embraced these symbols when designing an outfit meant to follow local custom.

666th world:

As the decisive clash erupted on the 666th planet, the kingdom's twin "Lazurite Swords" plunged into the heart of the fell dragon's territory, nearly severing its lifeline before falling to an inexhaustible swarm.

Just as all hope seemed lost, their lieutenants arrived with Octavia's backing. Tearing through the last obstacle,

they decapitated the fell dragon and returned the letters their commanders had penned, a sign that the day of sacrifice was over.

In the wake of their victory, the twin "Lazurite Swords" stepped down from their roles, bequeathing their legacy to their two lieutenants.

As the new generals took command, they committed themselves to sweeping away the last of the foe. Elements of the fell dragon's form were dismantled and forged into ornaments for their new armor,

serving as an unparalleled deterrent against the monsters that remained.

Octavia would always remember the heroic sight of the two new generals — including the silhouette of their slightly trembling hands as they signed the papers to pay her spaceship's damages in full.

For some unknown reason, the 666th planet harbors a deadly evil power that has caused monsters to ravage the land unchecked, and for decades, the "Kingdom's" troops have struggled to hold the line against these monsters.

However, a certain unit led by two field-grade officers has succeeded in penetrating the enemy line on several occasions.

Drawing on discoveries from a long-lost civilization made by two historians, and on calculations from the visitor Octavia, the two commanders were able to pinpoint the monsters' lair — the very same monsters that had caused the downing of Octavia's ship, it turns out.

67th World

Landscape & Environment

“On the 67th planet Octavia visited, advanced technology has brought evergreen crops that thrive year-round, greatly diminishing the effects of withering and decay on agriculture. Yet naturalism hasn’t completely yielded to technology. Unmodified ordinary plants—that grow, mature, and fade with the seasons—are still widely preserved as a vital part of the world’s original landscape.” (Autumn Veins description)

Three seasonal celebrations:

· Autumn/Harvest Season: “The autumn season of maturity and harvest, like on many similar worlds, is celebrated and cherished. Gold and orange, as primary colors, symbolize fruits and often evoke a sense of harvest, while azure represents vitality.” (Autumn Veins)

· Spring Festival: “Like many civilizations across the universe, they had a clear concept of ‘seasons.’ Though expressed in different languages, the season when crops begin to sprout and grow was

always given imagery similar to ‘spring.’ The people here likewise held lively celebrations before the arrival of spring to express their good wishes for the future.” (Prelude to Spring)

· Winter Gathering: “When it comes to winter festivals, there’s no celebration without a crackling hearth, a hearty feast, beautifully wrapped gifts, and—most importantly—joyful songs shared in reunion!” (Winter’s Warmth)

Memorable Encounter

“On that winter day, she arrived at a small, unfamiliar town and hesitantly asked for a place to stay. A kind family welcomed her with warm hospitality. The humble couple served her a generous meal, while their lively children performed melodious songs for her.” (Winter’s Warmth)

Octavia: “Before leaving, she gifted them the sweetest red fruit she had found on this planet as a token of gratitude.”

---

93rd World – “The Academy Planet”

“Though they possessed the ability to modify their entire planet and merge it into a giant academic collective…” (Astral Beacon)

“…the civilization to which the 93rd world—the Academy Planet—belonged still placed strong emphasis on basic geology and mapping.” (Astral Beacon)

“Of all the worlds Octavia visited, the 93rd was the most peaceful.” (Dawn’s Visionary)

“This was a pure Academy Planet with an impeccable scholastic atmosphere and living conditions, capable of constantly producing talent with wisdom, skill, and good conduct in equal measure for the civilizations under its purview.” (Dawn’s Visionary)

The phrase “for the civilizations under its purview” suggests the Academy Planet may serve as an educational hub for multiple civilizations.

Cultural Practices

Graduation ceremonies: “This Dawn’s Visionary set is, in turn, based on the most luxurious of graduation gowns. It reminds Octavia of the time she attended three graduation ceremonies in one day back in her younger years…” (Dawn’s Visionary)

Octavia Encounter

“A young man and woman saw through her. As it turned out, they had long yearned for both the skies and adventure, and while traveling through the clouds in a hot air balloon, they witnessed Octavia as she landed.” (Painted Skies)

“They longed for a life like hers, and thus agreed to keep her secret. Octavia, for her part, saw a certain romanticism in their attitude, along with similarities to people she once knew. Thus, she promised to take them on an interstellar graduation trip once they had completed their key studies…” (Painted Skies)

This reveals that students have awareness of interstellar travel.

“It reminds Octavia of the time she attended three graduation ceremonies in one day back in her younger years, along with classmates whose faces had grown less distinct in her mind over time…” (Dawn’s Visionary)

---

118th World – “The Forest of Steel”

Landscape & Environment

Complete urbanization: “After seven days of travel, Octavia wrote the following comment for the 118th world she discovered by chance: ‘The Forest of Steel.’ This was no exaggeration—cities sprawl across this world’s continents, weaving a seamless ‘civilized existence’ using steel, concrete, and strict regulations.” (Offbeat District)

Social Dynamics

“Within a broader system of ‘civilized life’ that placed immense value on work, the people of the 118th planet often suffered from health issues linked to sedentary lifestyles and excessive overtime.” (Orange Passion)

Octavia’s personal experience: “Octavia was not here long before she had received over 100 recruitment messages from professional headhunters, alongside double that number of health supplement ads.” (Orange Passion)

Counter-Culture Movements

Artistic rebellion: “Yet this order has also given rise to artistic groups who stand against the rules, the rising stars of which use this ‘Offbeat District’ to showcase their striving for freedom…” (Offbeat District)

Music performance: “Octavia, on a whim, visited a popular music performance venue. There, she mingled with the enthusiastic audience and enjoyed a vivid array of performances. A young but passionate duo left a deep impression on her.

It was said that once they made their name in the two-thousand-seat venue, they would step onto even grander stages, aiming to hold concerts in arenas with tens of thousands of spectators.” (Radiant Melody)

Sports & Competition

“Octavia encountered fierce fighting tournaments taking place within the steel forests of the 118th world. The trophy the contestants fought for would add an important feather to their city’s cap.” (Fervent Fighter)

Octavia’s Reflection

“Years later, when Octavia came across the costume records, she couldn’t help but wonder if they had reached their goal.” (Radiant Melody)

273rd World

Landscape & Environment

“Situated on the edge of its stellar system with insufficient sunlight, its land remains frozen in ice and snow all year round…” (White Flash)

“When the planet reached its farthest orbital point, the temperature dropped by another thirty percent, approaching the lowest point of particle kinetic energy.” (Frosty Plume)

The phrase “approaching the lowest point of particle kinetic energy” indicates temperatures nearing absolute zero.

Geographic features: “In top-tier competitions, athletes sprint down from mountain peaks that pierce through the clouds with slopes almost vertical…” (White Flash)

Civilization Level & Technology

“The severe winter was one of their greatest adversaries, but it also witnessed their complete establishment on every star in the stellar system.” (Frosty Plume)

**Cultural Practices**

“For this reason, people would hold elegant celebrations on the coldest snow night, and the attire of the two hosts was thus etched in Octavia’s memory…” (Frosty Plume)

Skiing culture:

“The most popular sport here is extreme skiing. In top-tier competitions, athletes sprint down from mountain peaks that pierce through the clouds with slopes almost vertical, diving at speeds faster than birds can follow, leaving only trails of pure white…” (White Flash)

“Octavia purchased this ski suit—youthful in style yet exceptional in performance—and attempted a dive that broke the local sound barrier.” (White Flash)

“When the planet reached its farthest orbital point, the temperature dropped by another thirty percent, approaching the lowest point of particle kinetic energy

. Even her coat, which could withstand gunfire and molten iron, could hardly endure this ordeal. Just then, a classical and elegant manor appeared before her, where two young hosts warmly graciously invited her inside and welcomed her to an elegant ball.” (Frosty Plume)

Symbolic Significance

“As it turned out, this place was regarded as a milestone for the civilization’s triumph over harsh environments.” (Frosty Plume)

712th World – “The Paradise Planet.

Landscape & Environment

“Every city in this world was a holiday haven with a unique theme.” (Scarlet Shade)

“Octavia served as a consultant on the 712th world she visited for 10 years.” (Fairyland Prom)

“While touring the 712th world, the Paradise Planet, Octavia encountered a phenomenon known as the ‘devaluation of happiness’: constant exposure to pleasure and entertainment gradually raises one’s threshold for happiness.

As such, a suitable amount of tranquility is necessary for both guests and the planet itself.” (Mystic Forest)

Octavia’s Design Solutions

Color psychology framework: “…the most important of which was the influence of color on emotion. At that time, two brilliant artists stood up to present Octavia with a multitude of fantastical plans.” (Chromatic Artisan)

“What should the main visual style of a theme park that wanted to appear solemn, elegant, mysterious, and opulent all at once be?” (Steamwave Chronicles)

“Octavia’s answer contained many elements derived from Fontaine in Teyvat and from local historical ‘technical aesthetics,’ which proved incredibly popular.” (Steamwave Chronicles)

This shows:

· Octavia actively uses Teyvat as design inspiration for other worlds.

Themed Districts

Ninja City (Inazuma-inspired):
“Once employed as a consultant, she would tell the people tales of distant Teyvat, and the people of the Paradise Planet would make special modifications to their pre-existing ninja city based on the Inazuman stories she told…” (Scarlet Shade)

Fairytale Theme Park:
“By the time she parted ways with them, the fairytales she told the children had already become popular, with many novels, picture books, and film adaptations, as well as a theme park of just the right scale.” (Fairyland Prom)

Timeline:

· Octavia tells stories to children
· Stories become novels and picture books
· Film adaptations are produced
· A theme park is constructed
· All within 10 years

Mystic Forest (Sumeru-inspired):
“As such, Octavia designed a serene ‘forest’ with the rainforests of Sumeru in Teyvat in mind—a place where people can slowly relax through a leisurely journey of exploration.” (Mystic Forest)

Steamwave Chronicles (Fontaine-inspired):
“Octavia’s answer contained many elements derived from Fontaine in Teyvat and from local historical ‘technical aesthetics.’” (Steamwave Chronicles)

Direct referral:

“After Octavia was accidentally struck by a high-speed comet, she followed the recommendations of the residents of the 712th ‘Elysium Star’ and made several transfers before arriving at the 722nd planet, the ‘Sanctuary of Recovery.’” (Healing Heart)

“Octavia was also invited to the opening ceremony, where she personally chose the most suitable outfits for the young men and women playing the leading roles…” (Fairyland Prom)

---

722nd World – “The Sanctuary of Recovery”

Civilization Level & Technology
“Here, the civilization’s finest doctors and nurses can treat various common—and even peculiarly shaped and fundamentally different—forms of life.” (Healing Heart)

The phrase “peculiarly shaped and fundamentally different forms of life” indicates that the Genshin universe contains biological diversity.

Cultural Values

“For some highly advanced civilizations, medical care has become an extremely important industry.” (Healing Heart)

The phrasing “for some highly advanced civilizations” implies that not all advanced civilizations prioritize medical care equally.

Octavia’s Experience

“After Octavia was accidentally struck by a high-speed comet…” (Healing Heart)

Given her survival, this reveals she has extreme durability.

“Octavia experienced what she calls ‘retirement life’ here for a while. Her wounds soon healed, and she was cared for with kindness and patience by two young medical practitioners who left a deep impression on her.” (Healing Heart)

“Before departing, they even took a commemorative photo together…” (Healing Heart)

This indicates:

· Photography technology exists in the 722nd world
· Octavia maintains physical mementos of her journey

Inter-World Reputation

The fact that residents of the 712th world specifically recommended the 722nd world shows interstellar communication networks capable of sharing information.

---

777th World – “The Magic Civilization”

Landscape & Environment

“A land of quietude and mystery, upon which all civilization was built on a foundation of standardized spellwork—where nothing can truly escape the grasp of ‘magic.’” (Phantom Night)

Atmospheric magic limitation:

“In this world—the 777th chronicled by Octavia—the magic that all things rely upon cannot seem to leave the atmosphere, thus binding the wizards, witches, and their wondrous creations to gravity’s well.” (Rose’s Lament)

External Threats

“Yet the threat from deep space continued to grow, and so the young scholars wearing the Rose’s Lament set undertook a bold experiment: imbuing magic into meteorite dust and doing all they could to send it back into orbit…” (Rose’s Lament)

Cultural Practices

“Moonlight descends, candles flicker, and the night of revelry begins.” (Candlelit Revelry)

“During classes, they proved skilled at extracting the essentials from obscure esoterica. And in their daily lives—and especially at the festival known to later generations as the Candlelit Revelry—

they would be like carefree young men and women, joining the students in fun but moderate pranks, even leading them in begging for candies from other teachers.” (Candlelit Revelry)

Post-Catastrophe

“The 777th world that Octavia chronicled once fell briefly into chaos due to calamitous meteorite showers.

Once the crisis had been properly handled and the relevant organizations had completed a set of perfect precautionary measures,

they then had ‘opera mages’—who used magic to create light effects, sounds, and visual tricks—take the stage, perform, and soothe the people.” (Sonic Ruins)

The Sonic Ruins group:

“The alternative opera group, Sonic Ruins, was a luminary leader amongst these mages…” (Sonic Ruins)

First encounter:

“The first friends Octavia made on the 777th world were two highly gifted and hospitable high-level professors of magic.” (Candlelit Revelry)

“During classes, they proved skilled at extracting the essentials from obscure esoterica.” (Candlelit Revelry)

Personal gift:

“Before Octavia left, the two designed a gown for their guest, one that they filled with sincere blessings…” (Candlelit Revelry)

Medical referral system:

“After Octavia was accidentally struck by a high-speed comet, she followed the recommendations of the residents of the 712th ‘Elysium Star’

and made several transfers before arriving at the 722nd planet, the ‘Sanctuary of Recovery.’” (Healing Heart)

“Made several transfers” indicates that no direct travel route exists between these worlds.

---

Teyvat is a planet located at the edge of a spiral arm. Currently, it is covered by a false sky meant to keep the Abyss out and make it more difficult to detect from the outside universe:

But now, it lay shrouded behind several impenetrable fields, its primordial flame stripped of the radiance it was meant to bear.

The Heavenly Principles set laws that outlanders—even some abyssal beings—must follow:

even invaders who seek to claim this world must obey its rules to some extent.

Unless the heavens split open and the earth’s defenses collapse, these star-born outsiders can do little more than linger at the world’s fringes,

whispering their madness into this realm; their attempts to seep inside amount to nothing.

The formless beast that soared through the starless void should never have required organs this world calls “wings.”

Those grotesque, profane appendages may have arisen to adapt to the laws beneath the moon, though Descenders may be immune to them to some extent—or perhaps entirely.

Races in the Genshin Universe:

· Skirk’s Race: Distinct from humans, as they have a fin on their back. They can also coexist with the Abyss to some extent. They are physically stronger than regular humans.

· The Voyager’s Race: A “scribe” whose mind travels the cosmos while her body rests in a distant celestial disk-construct. Her species are scribes who chart civilizations doomed to perish. She is not human—possibly an invertebrate or non-animal lifeform—as she refers to humans as “chordate animals.”

· Humans (or Humanoids): Many worlds have human-like societies, such as the worlds Octavia visited.

However, I’m a bit confused about the difference between humans in Teyvat and humans in other worlds, as humans in Teyvat likely originate from the Primordial One’s original world and might be biologically different from people like Octavia or those in the worlds she visited.

· The Travelers’ Species: Humanoid. They have extremely long lifespans and are basically immortal.

They can also survive and travel in space and don’t seem to need to eat or drink. I’m also not sure if the Traveler has to do things normal humans do, or if they just prefer to.

I’m also unsure if everyone on the Travelers’ home planet was like this, or just the twins. For the twins themselves, I theorize they are some type of god, as gods exist outside of Teyvat. They could possibly have been born alongside their world, like Nibelung.

· The All-Devouring Narwhal’s Species: Unknown, but it is likely beyond conventional biology.

· The beings Surtalogi beat: “If it was a wicked beast, he ate its flesh. If it was a god or a machine, he absorbed its energy. If it was a warrior or mage, he played with his food — forcing them to use every trick in their book, then cutting them down once he tired of the charade.”

· The rat Skirk ate: “Though, I should mention I brought it here from another planet, since all life on yours is extinct.”

· The creatures Skirk encountered:

“During my journey through the stars, I came across a species with completely inverted sensory perception. They’d use ice to warm themselves up, and cool down by the fire.

They’d be sweating buckets inside a cold, dark cave, but shiver uncontrollably under the blazing sun. So different from all the other creatures around them, and yet they lived quite happily. That’s the miracle of life — unfathomably complex, but at the same time so simple.”

Universal Concepts

The Abyss

The Abyss is a cosmic phenomenon and is likely the force destroying the Genshin universe. It is not limited to Teyvat; it hates, destroys, and has consumed countless star systems and worlds.

Will

The concept of will is not limited to Teyvat.

“Not all that comes from beyond may be one that ‘descends.’ That title belongs only to wills that can rival an entire world. That is what I seek: the way to become such a will—one that can protect the world, sustain the world, destroy the world, and create the world.”

— Notes #1, The Narzissenkreuz Ordo

The Voyager—an outlander not from Teyvat—noticed Nibelung due to his strong will:

“It came from an unremarkable little world at the edge of the spiral arm—and from the primeval dragon that had been born alongside that world. Though death would one day bring an endless night, and the sun it gazed upon was but a fleeting ember, this will, bound though it was to its planetary crust, shone more brilliantly than all the civilizations the voyager had ever seen.”

— Deep Gallery’s Distant Pact

“Ambition should be something that transcends the world below and the starry sky above—something that shines in unison with fate itself.”

— Narzissenkreuz Sword Lore

“A sacred blade indwelt with great enough reason and will to create and destroy a universe—or a dream.”

The Traveler’s sibling even stated that she would need the might of an entire world to speak to the Heavenly Principles as an equal, which may be a description of what it means to be a Descender.

Fate

Another universal concept is fate. The reason the Abyss started destroying the universe is that its fate was severed, and the Abyss is all the fates that never came to be. Along with Surtalogi being bound by destiny, this suggests there is a separate universal fate from the one the Heavenly Principles made.
