The body in cistern intrance?

[Adny]

Where should the body be?

The main pillar supporting the bridges (large one in the center of the room). The body will be straddles around it in a convex sort of shape. He faces the door to the prison area; so basically if you have low enough sanity in the prison and enter the cistern entrance (hub area), you'll be greeted with a naked guy strapped to a pillar. Oh joy.
