Human: Generate a short description of a foreboding cavern setting with an iron rack and a torch. Assistant: 
Soot from a little torch propped in an iron rack has feathered the sandstone walls with streaks of black, echoing the shadows that veil the far reaches of the room. The passageway narrows and lifts here, bringing the beam-reinforced ceiling closer -- so much so that this space would become almost suffocating if not for the fact that a slight breeze from somewhere ahead cools the air.
