Further into the large cavern complex, you notice that small pieces of
droppings are all around the floors, and walls.  The cavern are were through
the darkness, and stalagmites struggle to reach the high ceiling above.  The
only sounds that can be heard are the timed drops of water and the cries
from an unseen creature, lurking in the shadows.
