This large stone chamber is nearly completely filled with tables

covered with strange glass apparatus. Multicoloured liquids bubble and

move through tubes, combining in other vessels to form new

concoctions. The steel pipe that runs along the wall goes into a large

covered vat at the back of the room, where a thick bluish substance

churns and pulsates. In the far corner of the chamber, a heavy iron

trapdoor is set into the floor.
