The Everfall Spiral
A Living, Planetary-Scale Universe
A generative, self-sustaining civilization simulator governed entirely by universal physics. Tier Zero drops autonomous agents onto a procedurally generated planet and lets the math take over. Zero behavioral scripts. Pure emergent reality.
The simulation runs on a massive 30,000 × 30,000 spherical topology with 1 million vertex cells. Before a single agent spawns, the engine simulates millions of years of geological violence—tectonic subduction, meteor strikes, and weathering—to physically carve out the world’s biomes, river networks, and deep-crust resource veins.
Agents organically figure out how to survive and build communities. They naturally form Prigogine dissipative structures—literal “dance circles” in the streets that act as living zoning ordinances, physically preserving open town squares.
Without a single line of behavioral code, agents divide labor and specialize. Settlements naturally emerge, building pull-based supply chains, forming physical trade caravans, and establishing comparative advantage trade routes across the globe.
Memory acts as a selective filter. Agents pass down only their most heavily reinforced skills to their offspring, allowing families of farmers or miners to organically compound their advantages across generations.
The engine runs 8 recursive layers of systemic logic simultaneously—managing everything from weather and terrain to individual agent decisions and civilization-wide economics. It sustains thousands of agents and pushes a flawless 150 frames per second on a shockingly lean ~35,000-line codebase.
