Steam Tunnels

Warm, hissing, winding, neon-lit burrow worthy of a sci-fi novel, filled mostly with pipes that carry steam. Gauges and valve handles of all sizes and vintages sprout here and there from the conduits. The level of the stone and dirt floor in the main, walkable tunnel changes unexpectedly with the occasional puddle that is inevitable underground, but it’s mostly dry. The air is dry, too, and odorless, and the walls are completely free of tropical growths.
