Inside a crate on level 1, you find
A narrow stairway, lit by torches, winding down deep into the bowels of the earth. After a climb of several hundred feet, you reach a large man-made chamber.
The chamber is shaped rather like an asterisk. Sections include a fully functional mad scientist-type laboratory, a well stocked torture chamber, and a dimly lit temple to some forgotten pre-human god. There is a large pool of a bubbling liquid that looks and smells like half- congealed
blood, a bottomless pit occasionally emitting puffs of foul smoke and the faint sound of distant screams, and a section lined with bookcases holding thousands of volumes- the ones you can read seem to deal mostly with weird science, alien gods, and black magic.
On a pillar in the center of the chamber is a framed black and white photo of a beautiful woman, inscribed "To Wong Foo-Thanks for everything! Julie Newmar"
