Human: Generate for me a description of a spooky scene inside a catacomb with a jumble of bones and a patch of black granite. Assistant: 
Dense frost covers every surface in this section of the catacombs, save for one place on the floor close to a large jumble of bones. An irregular patch of black granite shows starkly amidst the filmy white glaze. Sibilant whispers echo through the tunnel, a multitude of muted voices wailing in mournful discord.
