This is a dim passageway in the Ghering Caverns.  Just enough glowing
lichen grows on the walls to provide light to see by.  The floor here is
stone with numerous patches of something slimy and slippery.  The air is
somewhat musty and rather humid.  The temperature is cool.  You can hear the
sound of animals scurrying about.  The passage runs north and south.
