Eleven all-new adventures for Mausritter

Available in print from Games Omnivorous and Exalted Funeral.

Huge and ancient, a mountain of stone. It stood even when the most wizened of mouse elders were young. The Estate dominates the landscape for miles around.

Nestled under the floorboards, the mouse settlement of Brickport, is beset by trouble on every side.

Above, huge creatures pace. The vicious cat-witch Sabrina jealously guards her domain. Outside, in the fields and pond and orchard, even stranger events are afoot. Can you help save the settlement before it’s too late, or will it be swallowed by the chaos that surrounds it?

The spitting pill bugs in science sorrows have 12 HP? This seems like a lot. In room 6 you encounter 2d6 of them! Maybe 12HP are a typo?

These are simply beautiful and imaginative!


What an absolutely phenemonal setting and varied series of adventurers from an incredible array of creators. 

I ran my first game of Mausritter last night using this and I absolutely can't wait til next week. The flavour and depth here is incredible, which, along with the sensibilities of the game itself, really inspired me to create my own characters and storylines in the moment. 

Truly a magnificent collection!


I wish there was a print-version included in the collection. As it currently stands the "pamphlet format" is a huge pain to deal with.

I'm currently running this as a campaign with a bunch of 40 yo and we're having a blast. It also lead me to discover Into the Odd and Cairn and I'm very glad.

Highly recommended.

Love this little adventure (new to Mausritter).  Would love it more for online play if the maps were available as jpegs unnumbered like what you did with the Bee-adventure.

Just followed the link to print pre-orders and it tells me that pre-orders are disabled.

Ah yes, I should remove that link. It’ll be up for purchase once the kickstarter & preorders are delivered.


Amazing compilation of adventures! Great art and layout, amazing flavour, cool NPCs and it includes the unlabelled maps to show your players!


Amazing collection! The definitive starter kit for Mausritter adventures, I felt like it offers a ton of great entry points for new players and fun locations for easy world building. Each adventure is beautifully laid out and fit together nicely as a collection.

I missed the kickstarter, but pre-ordered it on backerkit. is it possible for me to get access to the pdf collection as well?


Yep, you should get an email with a key for the digital copies. Send me an email (isaac at isaacwilliams dot net) with your details if you haven’t and I’ll sort it out.

The format is excellent and the adventures are awesome! Can someone explain to a non native english speaker what is an applejack (from the orchad adventure)? I only find stuff about my little pony and drinks.


Applejack is brandy made from apples. I assume its use here is clever wordplay on Rotten (Fermented) Apples!
