Brrrrr!  This area of the caverns is extremely chilly.  It almost feels
like there is ice nearby cooling the air.  The floor is free of moss and
slime, and has a few slippery places that could be ice covered.  There is a
bluish globe of light floating near the ceiling.  You think you hear some
sort of animal noises very near by.  The passage runs north and south from
here.
