You are walking down a foggy tunnel.  The tunnel heads diagonally,
apparently heading somewhere.  The fog is thick on the floor and lighter
above your waist.  You look to the walls and see strange drawings and
writings.  You see darkness ahead, and you look to your feet seeing nothing
but a shadowy imprint of your leg.  You cringe as you think of what might be
roaming around on the ground.
