The interior of this cave is quite dark, and without a light source you
don't stand much of a chance of finding your way around.  If the stories are
correct, there should be a small passageway around here somewhere that leads
to the room where the Grimoirium Magica was discovered.  There is a large
tunnel in the wall to the north, but it doesn't seem to lead anywhere in
particular.  Perhaps this is the section of the cave that the earlier
explorers refused to travel through.
