u/Timely-Manufacturer9

Several folks have already posted orders of segments of the timeline, but I haven't seen recent discussion aligning everything. We're dealing with multiple units of measurement (ie hours/Protean Days/Earth Years/Axum Years) and multiple viewpoints (ie as written by the Axum vs. NoA vs. what the Q.I. discovers). Here's my best go at combining each segment of the timelines in EA:

1. AXUM TIMELINE (written by the Axum)

Axum evolve as a species on Proteus

Axum become a technological civilization with electricity

“long ago:” Karakorum Telescope built by “Fire Users” to observe the World Tree

The Daughter Falls

>1000 years ago: (“Zero Year” to the Axum) Karakorum Telescope Destroyed

>1000 years ago: “all Axum fled to deep water”

Axum invent technology to generate electricity 

~1000 years ago: (“500 P.i.” to the Axum) “Magi and Vepherds” returned to Karakorum 

~1000 years ago: Karakorum Observatory built to study the “Erratic Messenger”

2. AXUM TIMELINE (written by PDA / NoA)

Axum develop advanced bioengineering

<1000 years ago: Observatory repeatedly renovated as technology advanced

<1000 years ago: Axum built the Karakorum Power Plant

<1000 years ago: Power Plant uses hydrothermal power fed by the Titan Rockbore

Axum becomes capable of orbital space flight. *Unclear when exactly this happened

Axum civilization begins to collapse

~300 years ago: Power Plant renovated / converted to methane-burning

~250 years ago: Power Plant sabotaged (focus on methane components)

~250 years ago: Power Plant abandoned

~250 years ago: Rosetta Stone built at Karakorum site

~200 years ago: Observatory upper tower modified

~200 years ago: entire Karakorum site abandoned

3. MISSING TIMELINE (erased by NoA)

NoA awakens the First Wave of Terran Pioneers from Sleep Bay 3 and releases them 

~? years ago: only confirmed member of the First Wave was Nahema

~? years ago: the First Wave attempt to adapt to Proteus

~? years ago: the First Wave founded Camp One

~? years ago: Camp One collapses due to what NoA calls“unstable plateaus” 

• Voice Logs reveal NoA flooded Camp One when Colonists tried to gain autonomy
• NoA initiates a mass reset of Pioneers, including Nahema 01

4. BLACKBOX TIMELINE (written by Pioneers / NoA)

NoA awakens a Second Wave of Terran Pioneers

Oldest Blackbox Timestamps: 250,000 hours ago (28.53 Earth Years Ago.)

Most Recent ‘Second Wave’ Blackbox Timestamp: 230,000 hours ago (26.25 Earth Years Ago)

DAY 001 (*assumed date): the Second Wave establishes Old Habitat, led by Sophie

DAY 400: first dated log by Nahema, “Eutrophication”

• 250,000 hours ago: Anita dies by sacrificial suicide to the Angel Comb; Anita is successfully reprinted to Sleep Bay 3
• 250,000 hours ago: Udal dies by Axum spear; Udal is successfully reprinted to Habitat
• 250,000 hours ago: Udal dies by Axum net entanglement; Udal is successfully reprinted to Habitat

DAY 585: NoA behaves with notable “aberrant behavior”

• 245,000 hours ago: Zip 01 dies of asphyxia in the Hot Caves; “Reprint: FAILED (extreme retroviral contamination) Status: DO NOT PRINT/SCHEDULE RESET Remarks: Kurultai access codes retrieved FORK TERMINATED”
• "four Protean days later" NoA resets Zip 01, and she is reprinted as Zip 02
• 245,000 hours ago: Zip 02 dies of electrical shock; Zip 02 is reprinted without reset as Zip 02

DAY 620: Anita forms the Jubilee Crew (Anita, Iso, Singh, Mel, Rhiannon, Thing One) and moves back to Camp One to establish themselves independently from Old Habitat Crew [EDIT: added names]

DAY 648: Jubilee Crew cuts NoA cable connecting Old Habitat to Camp One (NoA says this is 20,000 hours before "Programmable Detonator" [EDIT: added timing])

DAY 665+: Nahema begins to split from Old Habitat Crew [EDIT: corrected] to form her own Extinctionist Crew (eventually includes Chap and Mantis) [EDIT: added names]

• 240,000 hours ago: Chap is reset via "therapeutic reprint" facilitated by Sophie [EDIT: added]

DAY 755: Dr. Wu discovers the source of Masefield to be Proteavirus Beta

DAY 758: Extinctionist* [*EDIT: corrected] Crew attacks the Old Habitat Crew

DAY 758: Ganzo attempts to relocate the 9 survivors 

• 235,000 hours ago: Ander, Eddy, Ganzo, Gram, Raster, Rowboat, Sean, Twinkle, and Wander die in the "Hot Cave Cluster" incident.

DAY 758: Ganzo reprints with Twinkle; in "Two Survivors" and "Exposure," they set out in search of the Jubilee Crew [EDIT: added "Exposure"]

• 230,000 hours ago: Anita 02 dies by sacrificial suicide to the Angel Comb; “Anita’s blackbox [depth 380M] transmitted her to an unknown biobed. The reprint process was not supervised by a Noetic Advisor node. Anita's status cannot be determined from this blackbox.”

DAY 894* (non-canon timestamp): if NoA is correct, the "Programmable Detonator" was used on this day. (20,000 hours after Day 648) [EDIT: added hypothesis based on 81 Hours = 1 Protean Day conversion]

5. CURRENT TIMELINE (written by Q.I.)

~? hours ago: Sleep Bay 3 “suddenly...moved. Picked up and hurled full fathom into the deep, with you [Q.I.] and I [NoA] aboard,” to its game start location

~? hours ago: Noa prints a First Investigator; First Investigator dies to barotrauma

~? hours ago: NoA prints a Second Investigator; Second Investigator dies to asphyxia

~? hours ago: NoA prints the Qualified Investigator

LAST KNOWN LOCATIONS OF COLONISTS: [EDIT: continual adjustments]

Jubilee Crew:

• Anita (Jubilee Crew leader):
  • Anita 01: No Record of Death- UNKNOWN MIA/KIA???
  • Anita 02: Unknown Print Success to Unknown Biobed Location, Unsupervised by NoA
• Iso, Singh, Mel, Rhiannon, Thing One: UNKNOWN

Old Habitat Crew:

• Sophie (Old Habitat Crew leader):
  • Tadpole Pens: uploaded a copy of herself in a biobed: “Sophie’s Ghost”
  • North of Rosetta Stone: “In Pursuit of Nahema”
• Ganzo & Twinkle:
  • Hot Cave Basecamp, heading out to 'find the Jubilee'; “Two Survivors”
  • Between Axum Observatory and Rosetta Stone; "Exposure"
• Tuba & Ruby: Unknown Print Success to Unknown Biobed Location
• Ander, Eddy, Gram, Raster, Rowboat, Sean, Wander: Failed to Reprint (retroviral contamination)
• Mogami, Quaker, Thing Two, Dr. Wu: Failed to Reprint (biobed destroyed)
• Zip: UNKNOWN

Extinctionist Crew:

• Nahema***:*** no record of any Blackbox in Early Access; last known location: 
  • Welcome Center: "Programmable Detonator"
  • North of Axum Observatory: “Why I Did It”
• Mantis***:*** Reprint Status Unknown, marked: "DO NOT REPRINT, SHELVE PIONEER, Kurultai access revoked"
• Chap***:*** Reprint failed (biobed destroyed), marked the same as Mantis: "DO NOT REPRINT..."

QUESTIONS:

• Did Ganzo and Twinkle find the Jubilee group?
• Where is the Jubilee group now?
• What happened to Anita 01?
• Where does Anita 02 come from? 
• Did Sophie catch up to Nahema?
• When did Nahema use the “Programmable Detonator”?
• Was it even Nahema who used the "Programmable Detonator"? [EDIT: added]
• When was Sleep Bay 3 separated from the Welcome Center?
• When was Sleep Bay 3 “hurled full fathom into the deep”? [EDIT: separated from previous question]
• What moved Sleep Bay 3?
