 ## Elevator Pitch
 
-> An AI NPC world where the player spends SECOND to inhabit one eligible NPC-like body, lives through that body in a Town or Relay Yard, risks TIME in Gate missions, builds the settlement, and loses the body on death. Selected account and soul-layer progress survives, but continuing play means spending SECOND to inhabit another eligible body.

 The world exists before the player arrives. It is a society of AI NPC bodies with names, jobs, memories, relationships, stats, TIME, injuries, voices, and local history. A real player account spends SECOND to inhabit one eligible NPC-like body, then lives with the consequences of that body's strengths, flaws, duties, and social ties.

Death is meaningful because the body is lost. It is not a normal respawn.
