A large, inconspicuous set of steps descend to this deep hallway in the
keep.  The walls are made of made roughly hewn limestone blocks.  Unlike the
rest of the keep, this area's walls have been built and not just dug out. 
The floor is made of large marble tiles, and very clean ones to boot.  This
place is unusually clean.
