Human: Produce a magical scene inside of a cavern with minerals, lichen, and walls. Assistant: 
Old rusting hooks are still embedded in the rough walls of the tunnel, though they hold little but air these days. Lichen grows in small clumps on the walls, filling the room with a fitful, unearthly illumination. Scintillating out of the corner of your eye, minerals glitter in a Fae sugar-coating on the rocks and stones.
