A huge stone room filled with pipes and tubes. Large arcane devices studded with blinking red gems buzz loudly every few seconds, humming and clicking in between. The pipes run from the 20' high ceiling in the west into the floor in the east and range from 4" to 1'6" diameter, constructed of a strange metal.

• Devices: these filtering and recycling machines are near complete collapse. Any interference with their operation immediately causes a flood of orange fluid to spill out, doing d4 damage if touched.
• Pipes: under pressure. Behind them a panel is hanging loose; provides access to 1.18 via maintenance hatch. Getting through the pipes is dangerous; Dex save or cause acid to spray out, doing 2d6 damage to all in close range.
• Strange metal: the pipes are titanium and are impervious to acid and will not corrode.
