So... frustrated...

(yes, there's a story here).

OK, so my dad is pretty much the best DM ever, but he's decided that with all of us kids off at college, he's done DMing, so he gave me all of his old notes. The guy has - for one campaign world that he designed - 11 pages of notes on random cities and various locations within them. The frustrating part is that I found this old dungeon he designed, and it's clear that part of it is a chess puzzle. I enjoy a game of chess every now and again, and literally every single player in my campaign was on their high school chess team, so I figured I'd try and see what the puzzle was. That's the ONE DUNGEON I can't find any notes for. *weeps bitter tears*.
