The hallways here are completely dim here, almost to the point of being
pitch-black.  Yet thre 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.
