Human: Produce a detailed written description of a dreary cave wilderness setting with mud and a mud-smeared glowstone. Assistant: 
Eddies of turbid water stir up dark clouds of muck from the slurry of mud and pebbles that grudgingly offers up what little insecure footing can be found along the passage. A mud-smeared glowstone jammed high in a corner emits tenuous light, and the chill air is thick with the smell of damp earth and stone.
