Human: Write a detailed description of a foreboding scene inside a cave cavern with rock and cracks. Assistant: 
The roof and back wall of the cavern close in tightly giving a cramped feel that is unrelieved by the drab dark rock walls. Low light masks imperfections in the rock and it takes a few moments for the eye to adjust before the room's character comes into focus. Several cracks in the east wall vary in width and height but one appears large enough to squeeze through.
