The trifold is where it all started. I realized I could get pretty much all of the game rules on the trifold, so I crammed them in there. I only had to drop a little in the Obstacles & Enemies section, but I think it's worth it.

The trifold has the rules on one side of the page and the Mysterious Dungeon on the other.

Enjoy! I'm grabbing the dice right now to run through the Mysterious Dungeon again.
