This is a rough-walled passage in the Ghering Caverns.  It is flooded
with an ivory light from a strange-looking globe floating near the ceiling. 
The walls and floor are of stone and patches of earth.  To the east is a
room with reddish light to the west is a room with yellowish light and to
the north is a room with ivory light.
