Nine tanks full of murky, stagnant metaline act as pillars in this room. On the side facing the room center, each has a series of broken instruments, once used to display various details about the tank’s contents. An automatic door leads west, and a maintenance panel on the east wall leads to 3.8.

• Tanks — Opaque fluid behind thick glass. Bright light reveals a motionless mutated corpse inside each. Breaking the glass requires 72 points of damage, done with strikes that do at least 8 damage each. If the contents spill out, the disgustingly slimy fluid has the same effect as the metaline river in 3.5. The creatures inside are varied, with one of each of the PCs’ races being represented in addition to others.
