Human: Write a detailed description of a spooky cave in the wilderness with creepers, an ironwood tree, and a crevice. Assistant: 
Gnats and other flying pests swarm about, moving in as if working with a single mind. An antediluvian ironwood tree lays collapsed across the opening above, partly blocking the view. Thick creepers and other hanging plant life sway to and fro suspended from the fallen tree, partially concealing a dark crevice in the wall.
