Human: Make a detailed written description of a spooky setting inside a cave cavern with dust, bones, skulls, and an abandoned firepit. Assistant: 
A pile of discarded skulls and bones lies at the base of one wall, gleaming dully in the dim light. The walls here are stained a smokey grey, darker near the lower areas where an abandoned firepit is slowly being consumed by the steady accumulation of dust on the cavern's floor.
