Working on my world/universe
Working on many things including some sort of corruption from the Scar, different species, etc. I'm open to any ideas or suggestions. Edit: here you go. Here's more context
(I type fast by the way. And this entire thing has been an idea of mine for a while.)
My world is a large science-fantasy universe where advanced technology, magic, ancient gods, dragons, and interstellar civilizations all coexist. Millions of years ago, a powerful civilization called the First Dominion united hundreds of species and mastered both magic and science, treating them as parts of the same force. They ruled countless worlds before discovering a mysterious cosmic wound in reality known as the Horizon Scar. Shortly afterward, their civilization collapsed, leaving behind ruins, relics, and unanswered questions.
The Horizon Scar leaks a corruption called the Black Tide, which twists creatures, warps magic, alters reality, and slowly spreads across the universe. Standing against it is The Sentinel, an ancient guardian created by the First Dominion to watch over the Scar. For millions of years he has protected reality from whatever lies beyond it.
The universe is inhabited by many species, including Humans, the dragon-descended Drakari, the magically gifted Aetheri, the machine-like Forgekin, the nature-bound Sylari, and the shadow-walking Nyth. Every race has its own beliefs about The Sentinel, the Black Tide, and the lost secrets of the First Dominion.
The current era is known as the Age of Fractures, a time of competing empires, lost relics, ancient mysteries, rising corruption, and forgotten truths. Nobody knows exactly what caused the First Dominion's fall, what exists beyond the Horizon Scar, or why The Sentinel has remained at his post for millions of years. I' m looking for ideas for species, factions, religions, kingdoms, magic systems, ancient threats, legendary heroes, cosmic entities, First Dominion lore, and anything else that could help expand this universe.
