01
Describe
Start with a place, people, economy, institutions, history, and rules in plain language.
Enreef Worlds
Create a world. Let it keep living.
Give Enreef a place, population, economy, institutions, history, and rules. The world fills with people, households, businesses, relationships, and consequences — and keeps moving forward through time.
Create from a description
Describe it. Enreef brings it to life.
"Create a remote Pacific island in 2035. Population 10,000. Housing is scarce. Tourism provides 60% of the economy. Energy is limited. Two political movements are competing over rapid development. A major storm season begins in four months."
Enreef turns the description into explicit world state: geography, households, housing, jobs, resources, institutions, economy, relationships, rules, and starting history. You can inspect and change any of it before the world moves forward.

Three ways to create.
02
Start from structured state
Use imported data, maps, lore, structured inputs, or an existing world as the starting state.
03
Fork an existing world
Branch any world, change what matters, and let a new history unfold from the same past.
Live inside the world. Or change the rules.
Every mode operates on the same persistent population, relationships, history, and world state.
Observe
Watch the world move on its own. Follow people, households, businesses, neighborhoods, institutions, and events as history accumulates.
Live
Enter one life inside the world. Work, build relationships, make choices, and live with consequences while everyone else keeps moving.
Build
Run a company, choose locations, hire people, set prices, and compete for workers, customers, resources, and space.
Change
Alter policy, infrastructure, resources, weather, technology, or the rules themselves — then run the world forward and see what survives the change.
Leave the world. Come back later. It moved on without you.
