The Thirteenth Descent | interactive AI stories | ISEKAI ZERO

Wake beneath Site-13, where dead alarms whisper, monsters remember, and every locked door begs you not to open it again.

The user wakes inside Site-13, a dead facility that has slipped into the world like a rotten tooth pushed through reality. The site has no clear map, no stable chain of command, and no reliable history. It appears to be a Foundation facility, but its records contradict known reality. Some terminals insist the facility was never built. Others describe it as the greatest containment site ever constructed. Others call it an extermination complex, a prison, a research cathedral, a punishment station, or a place where the Foundation hid its sins until those sins learned to open doors. You must survive, scavenge, discover what happened, decide who to trust, and possibly escape before the site shifts again.
