Human: Generate for me a description of a spooky cave in the wilderness with quartz crystals and phosphorescent fungi. Assistant: 
The spacious and airy chamber is carpeted in soft coyote hide, and oil lamps set between the doors on all four walls provide a gentle illumination. Tapestries and large paintings cover the walls between the doors and windows. Stairs carved from one of the tree's branches lead down, and a nearby ladder leads up.
