A small dark tunnel, numerous lichen line the walls.  The cave continues
on to the south and you think you see a light at the far end of the tunnel. 
The floor of the tunnel itself appears to have not been walked on for quite
sometime..  By anything human that is..  Numerous scratch marks have been
scraped into the cave's stone floor.  
You dodge out of the way of a large stalactite that is dislodged from the ceiling!
