Truncheon World is a truncated version of the Dungeon World rules, to be referenced by the GM during the game and during prep. The material here is presented in a slightly different order than in the Dungeon World book.
"I got sick of lugging my hardcover copy of Dungeon World around. I thought it would be much easier to just have the GM section in a book and that's it. All the PC stuff is on the character sheets, and I mostly run prepared dungeons (or Dungeon Planet stuff) so I have monsters in my prep already.
So I made Truncheon World, a [digest-sized] book with just the GM sections and the rules I might want to reference when running the game."
