Princess Nell and Harv climbed the stairway into one of the bastions 
flanking the Dark Castle's main gate. These had narrow windows where in olden 
times soldiers should shoot arrows down at invaders. Harv tied one end of a 
rope to a hook in the wall and threw it out one of these slits. Princess Nell 
threw her Night Friends out, knowing that they would land harmlessly below. 
Then she climbed out through the slit and down the rope to freedom.
