Rinn is a Mausritter realm enclosed within an ancient stone wall abutting treacherous cliffs and pounding sea, full of warring factions, curious characters, and untold adventure.
Within its walls ancient towers of light and stone dominate the landscape, long since abandoned by the Fatachs. Their colossal stone wall encloses the inhabitants of RINN, with treacherous cliffs and pounding sea to the east.
A tenuous alliance of mice and birds rule over RINN. The High Mice ruling with malice and greed, the Children of The Light on a zealous quest to discover the truth of The Light, and the mercenary Corvid driven by a lust for trinkets and treasure. Rumours of rebellion abound and the downtrodden grow restless.

What is Rinn? Rinn is a sandbox realm for Mausritter offering a walled world full of warring factions, curious characters, and untold adventure.
It is a setting that offers the choice of exploration and discovery, where mice can travel the length and breadth of Rinn, from the mysterious and magical Pricklewood to the majestic Bright Tower that sits on the edge of the known world.
And if they so wish your mice can embed themselves in the political machinations of Rinn. Assist the ruling alliance and profit off their position, or bolster the rebellion in an attempt to overthrow the seated regime.
Introductory adventure The Inquisition Imposition is an adventure that can be used as an introduction to Rinn, that pulls a party of mice to and fro across the physical and political landscape of the walled realm.
