The Cavern of Many Mouths is a winding natural chamber whose floor is littered with bones and broken remains. Dark openings and pits interrupt the rock, giving the impression that the main passage is only one visible part of a much larger network. The map is narrow enough to control movement but irregular enough that characters can never see the entire route at once.

For a GM, the name becomes a tactical feature rather than mere atmosphere. Creatures can emerge from side openings, retreat into darkness or threaten the party from several directions while the bone-strewn floor signals danger before initiative begins. In Curse of the Lady's Light, it works as one of the rough wilderness caves surrounding the more formal ruins. It can be reused for burrowing monsters, a scavenger den or any cave system where the walls themselves seem full of possible entrances.
