You are walking along a tunnel, that slopes downward to the east.  The
walls are cut from the dirt, and as you touch one side, a small piece of
dirt falls down.  The ceiling is relatively low, and the ground very hard. 
The tunnel becomes more narrow here, and the ceiling starts to become
higher.  To the east the tunnel gets darker and darker.  
A young fey is playing on the ground next to your feet.
