27H HALL OF HEADS. The entry cave quickly becomes worked stone after a few feet. The room is lined by bizarre stone heads worked into the walls, each with a gaping mouth and vacant eyes. The heads are greater than the height of a tall man and their features are deformed, stretched, squashed, and otherwise strange. Three of the mouths actually open into hallways. The loud buzz coming from the noise room, 27L, can be heard to the north.
