This room is fairly dark and breezy.  You hear the spooky sounds of wind
howling throughout the large tunnel down here.  Looking above you, you
notice that the source of the wind seems to be coming from a grate in the
ceiling.  The grate also gives off the only light that you see in this area.
You can't spend much time in here without getting scared from the eerie
howling around you.
