The walls themselves tower above you on either side.  You get a feeling that
you are getting smaller and smaller as you walk through the massive passage.
All along the walls are arrow slits pointed in towards you..  You get a
feeling that running through here with evil on your mind is not the most
intelligent of ideas...  Unless of course you want to go through what could
be considered the biggest human meat grinder in the universe.  
A castle peasant stands here with a bored expression on his face.
