This tiny rarely used passage has either just been recently revealed or
is passed over for more popular routes.  A thin layer of mist hovers close
to the walls, it seems to be rising from the fragile layer of moss growing
between the stones.  The eerieness of the mist gives the tunnel the
appearance of a graveyard.
