Human: Generate a short description of a mystical scene inside a cave cavern with sigils and stones. Assistant: 
After snaking around a series of rocks grouped around the narrow crevice giving egress, the chamber widens into a comfortable size. Around the perimeter are hollows where drifts of small boulders have been collected. A number of large stones stand upright in a circle in the center of the area, their surfaces covered with faint, incised sigils.
