Human: Please generate a brief description of a foreboding chasm in the wilderness with lichen and bones. Assistant: 
Several gouges mar the walls on either side of the cramped passageway, deep enough to fit a giantman's arm within. Pale lichen festoons the small ledges upon the scarred earth, trailing toward the floor in thin waves. A few shattered bones lie beneath the fungus, each obscured by the fuzzy grey-green tendrils.
