A Dim Hallway                                          -      N      -

The hallways here are completely dim here, almost to the point of being
pitch-black.  Yet there are many small glowing balls floating above you,
just out of reach.  They radiate a warmth that reaches deep into you body,
and yet they seem not to be there, giving off no light.  The walls have been
ground smooth, gleaming and polished to a bright grey luster.  The floor
shows no sign of wear, despite the obvious traffic.  
A black figure flies high above you in the crevases of the cave.
