The cavern here is dark, cold, and wet.  The uneven ground forces you to
be careful where you step.  You hear the sounds of rocks and pebbles falling
in the distance and you fearfully glance overhead at the dagger-like
stalactites protruding from the ceiling.  Small rivulets of water trickle
down the walls and you have an eerie feeling that you are being watched by
something lurking in the shadows.
