Maus' Vomatorium
the chamber that ate her, and the gall that did the eating
The ornate stone chamber where the bones of Fela Maus float in a marble coffin atop a dais, leaking yellow gall from a bubbling lid. The flagstone floor has been eroded by pools of green and yellow gall over centuries; the sour stomach-broth corrodes flesh but not bone, dealing d6 damage per round to any flesh that nears the dais. Floating with her bones is the Roseate Baritona, her cursed organ.

Whether the gall is Maus' own bile, leaked perpetually from the curse, or some older fluid the bog hag piped in, is unstated. The room's pre-curse purpose — a private chapel, a feast-hall, a Roman-style vomatorium of the literal kind — is unwritten.
