This one is a sort of tomb set up. Assume the PCs start on the lower left...A and B can be some clever features if you have time to think of any. You'll have to think of a reason that the prisoner is still alive...(click to enlarge)

This one is an abandoned castle, floors 2 and 3 respectively (first floor's boring, I assume). Start on the upper left. The void in the center is the castle's central courtyard. Unless you put in some intelligent monsters, assume many of the locked doors are actually just stuck or rusted shut.
