d100 Horrible Secrets In the Castle

Castles both old and crumbling ruin or vital bastion of the nobility have their secrets. Every slightly spooky castle deserves a few odd things. Even the nice palace in a good kingdom might have a secret nobody wants to know. Spice up any overnight castle visit. Will end up in my gothic compilation update.
