This is where the Master Mage keeps his more dangerous pets.  The walls
are covered with protective glyphs that glow and pulse.  The light comes
from several floating globes, which float and bounce about to illuminate any
part of the cage being observed.  As clean as the room looks, there is a
very odd smell coming from somewhere.
