This is a dim passageway in the Ghering Caverns.  A globe of faint,
colorless light provides light to see by.  The floor here is stone, with
numerous patches of something slimy and slippery.  The air is clean and
rather humid.  The temperature is uncomfortably warm.  You can just make out
signs that something has been here before you.  It is clear that you need to
watch your step, or you may be introducing your posterior to the slimy
ground in a manner that could be rather painful.  The passage here runs
north and south.
