Ordinary people wake up inside a tower. A voice in every head gives them one rule: reach the top and you go home; die in here and you're gone for good. You don't play them. You watch.
A nurse, a welder, a bike courier, a retired professor. They arrive with only what was in their pockets and know nothing about the tower. Some are gamers and expect game logic, and sometimes they're right.
Each one thinks with a language model running on your own computer, shaped by a personality, a job back home, a backstory, fears, quirks and a reason for climbing. That mind makes their real choices. Push on or fall back? Who gets the one crystal the floor dropped? Do they keep the promise they made to the friend beside them? Nobody is controlled. The tower just keeps count.
Hundreds of people come and go. They make friends and enemies, form factions, and keep a shared journal of what killed whom. They tell each other stories that get a little bigger with every telling.
A monster that kills someone can earn a name and a grudge. A desperate stand gets the place named after whoever held it. And when someone dies, they stay dead.
Faith promised me the next crystal but took the Gale crystal for herself. She prioritized her own gain over our agreement.
Some of the people who came before them left marks on the walls. Some floors seem to know who's climbing them. And not everyone in the tower is quite what they say they are.
