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.  You might also be
able to discover a route leading down into the depths of the mountain, but
exploring alone could prove quite dangerous.
