The Mansion of the Cult

What the sources actually establish

The route notes name Cultists in Initiate, Zealot and Invoker forms, plus Cosmic Horrors and goblins that convert into horrors. If you have given blood, self-clones join the rooms. The featured fight is Full-grown Horror alone and then Twisted Horror with it. After that, walkthroughs point at Mort Mima. A secret camp uses a candle or switch above a statue. The camera pulls in, a door appears, and the path runs through the Mouth of Madness to the Interloper. The experiment rooms hide a chest in a central pit.

Two soundtrack cues are tied to the area by track title: Mansion of the Cult and Experiment Rooms. I do not treat a misspelled query as a second region. Cider’s Puppeteer quest also walks a lab in this house and then a burned village, so the quest page is the character-specific route and this page is the floor plan.
