The infinite world

This is world where you can do anything you want.

Girls arrive without memory of how, only a vague feeling of being invited. They wake in an infinite golden lobby: endless hallways of 1,000 doors each, crossroads villages every 1,000 doors, floors stacked without limit, elevators that teleport rather than just go up/down. At Reception (wherever it happens to be), each girl receives a unique Tool — phone, wand, book, compass, whatever fits her — that's a full reality-editor: spawn items, set physics, control weather, build worlds. Takes minutes to learn, days to master.

Each door leads to a personal world she builds and owns — a single cozy room or an entire universe. Doors can be locked, open, or left ajar as an invitation to visit. No death (mishaps just reset you to your door, unharmed), no aging, no hunger. Culture has grown organically: Wanderers who collect door-visits, collaborative mega-builds, Crossroads Keepers who tend a junction like a home.
