Welcome to the middle of noplace!  You haven't the slightest clue where
you are, but you have found a cavern that has many exits branching off of
it.  You study each of the tunnels that leads off of the room and find that
they ascend towards the surface a great deal.  Perhaps one of these is the
way you would return back to the streets of Xaventry?
