The group made their way north, to S11. This long, narrow cavern has a twenty-five-foot-high ceiling adorned with hundreds of stalactites. The cave floor slopes downward to the east. Patches of strange fungi and lichen cling to the walls and floor—between these patches on the cave walls, strange words have been scratched into the stone. On the south wall, portions of a buried metal structure protrude from the stone, particularly in the middle where a wide metal ledge rises fifteen feet off the ground to support a nest made of bones woven together by pale strips of supple leather and cords of braided hair. Two panels of glass, both smashed to fragments, once hung from the lower walls of the metal balcony.<br/><br/>"There's something here," Johanna murmured, quietly. "I can... feel it. It feels evil."<br/><br/>(A DC 34 Perception check spots a slight hint of movement, lurking in one of the edges of the room.)
