Pure Observation
Watch civilizations rise, collapse, and be forgotten. Your role is witness — no decisions, no interventions, only presence.
AI-Powered World Simulation
Witness the Birth of
Alien Universes
Nine AI agents collaborate to generate narrative, illustrations, and voice — building worlds that have never existed, with histories no human has written.
A New Kind of Experience
Observer, Not Player
You don't build, you don't fight — you watch. Nine specialized AI agents work in concert to generate every species, civilization, character, and crisis. No two worlds share a history. Nothing resembles Earth. Each universe is procedurally alien, alive only as long as you observe it.
9 AI Agents
Coordinator, Theme Keeper, Species Creator, Character Writer, Place Designer, Civilization Architect, Story Writer, Historian, Artist Director — a full creative team.
3D World Map
A procedural Babylon.js terrain grows in real time as events unfold, placing civilizations and characters as navigable markers on the world.
Three Aesthetic Tones
Light / Whimsical, Epic / Dramatic, Dark / Mysterious. Art style, voice narration, and narrative register all transform to match your chosen tone.
Era Transitions
Worlds advance through historical ages — Primordial to Future. Only what matters survives the transition; the rest is archived into myth.
History Library
Five views into your world's past: Events feed, Timeline, Encyclopedia, Relationship Graph, and curated Collections.
