The heat engulfs you as you make your way down the tunnel.  Up ahead you
see a light.  A figure can be seen through the blinding light.  It appears
to be no taller than 3 feet.  The floor up ahead is smooth and solid,
contrasting with the rocky tunnel floor leading up to it.  You see a large
machine in the corner of the room, shaped almost like a rodent.  Odd
thoughts overcome you as you think of what it might be used for.
