You are in a prison cell.  This place smells horrible.  The cold, damp
walls are made of solid stone.  The wind beats at you from the small barred
window in the wall.  Long iron bars make up the door to the cell.  The
ground is made of a solid rock base, preventing happy diggers from escaping.
In the corner of the cell you see a skull, bearing a look of horror.
