For game masters & worldbuilders
A co-GM that keeps your whole world in its head.
Running a world is a memory problem. Who rules the north, which faction owes whom, what the party swore three sessions ago. Aethera holds the entire setting so you can focus on the story at the table.
Build your world once — lore, factions, places, NPCs, rules — into a linked database the AI reads before it narrates. Your cast keeps their history and bonds. A living calendar keeps time moving. And when the party breaks canon, you branch instead of scramble, keeping every path intact.
It's a co-GM, a world bible, and a session tracker in one — for solo worldbuilders and long-running campaigns alike.
What you'll use most
One world database
Codices for characters, factions, places, items, powers, and house rules — organized into folders, linked together, and pulled into a scene exactly when the moment calls for it.
NPCs that remember
Your whole cast with tracked bonds, relationship shifts, promises, and what each of them recalls from earlier sessions. Consistency without index cards.
A living timeline
Dates, time, moon phases, custom events, deadlines, and sessions on an in-game calendar — so pacing and consequences unfold on a real clock.
Canon you control
Edit history, branch from any moment, preserve alternate paths, and keep your world's truth intact even when the party goes sideways.
Dynasties & legacy
Map families, heirs, hidden bloodlines, and the bonds that shape your setting across generations — perfect for long-running worlds.
Make it yours
Extend Aethera with reusable mods — templates, trackers, sheet sections, mechanics, prompt packs, and story tools. Build the table you want to run.
Aethera is in active development, with access opening in Private Testing. Bring your own AI key across five providers, and export your worlds anytime — they're yours to keep.
