Moving on through the southwest door -
The ceiling of this 20-foot-wide hall rises to an apex 20 feet overhead. The floor, walls, and vaulted ceiling are composed of smooth black stone that almost seems to absorb light. Two cylindrical iron cages, each one 5 feet tall and 2 feet wide, dangle from the ceiling by iron chains. The base of each cage hangs 5 feet above the floor.
A strange sculpture stands in the middle of the hall between the two cages: a 5-foot tall column of roughly hewn gray stone covered with sharp protrusions. Four crystal-tipped appendages jut from the stony mass, each one pointing in a different direction.
A closed door lies along the east wall in the south-eastern part of the room, and a corridor ends abruptly at a wall in the southwest.
