The Fifth Floor of the Inner Ward consists of two towers. In the East Tower is the continuation of the chambers that once belonged to the powerful arch-wizard Calester. The Fifth Floor of the Northwest Tower is merely a guard post with ballistae for fending off aerial attack.
The walls, floors, and ceilings in the East Tower are made of an otherworldly-appearing dark green stone, except where noted otherwise. Ceiling height is uniformly twelve feet.
The walls of the Northwest Tower are gray dressed stone, with wooden beams supporting the ceilings. Floors are also made of wood planks and ceiling height here is twelve feet.
The Fifth Floor directly connects to the Fourth Floor only.
