Human: Produce a detailed written description of a spooky scene inside of a catacomb with niches and stairs. Assistant: 
Winding serpentinely back and forth, frost-covered stairs lure one deeper into the catacombs. Stale air wafts up from the subterranean passages below, carrying with it a hint of ice and decay. The darkness of the tunnel is broken by a single lantern, which casts wavering shadows over the bone-filled niches lining the walls.
