Mouse Guard is a roleplaying game based on David Petersen's comic of the same name. It's a gritty, mundane fantasy setting in which the player characters are mice belonging to an organisation dedicated to the protection of their fellow mice - the eponymous Mouse Guard.
For the past few years, I've been running a campaign based on a UK setting (the original is most definitely North American, judging by the fauna). I've developed a few generic resources to help play the game (these mostly duplicate things from the 2ed boxed set), as well as some more setting-specific resources.

Generic Resources
The cards below are all designed to be printed at 100% scale on A4 paper and cut down to give poker card-sized cards. I've had a good deal of success printing them double-sided, then laminating them (preferably in matte laminating pouches) before trimming to size. For a finishing touch, use a rounded corner punch to trim the corners of the cards to make them nicer to handle.
Campaign Resources
My campaign is based in the United Kingdom, specifically in an upland area in the Derbyshire Dales (which is also where I've been running the games).
