This campaign is inspired by the Mouse Guard series, mixed with elements from The Secret of NIMH and Monty Python and the Holy Grail. Our story features a group of mice, recruited by a wizened rat to seek out an artifact thought to hold the power of eternal life. Our heroes will venture into the wild lands beyond the Scent Border, seeking clues about the lost legacy of a powerful rat civilization that apparently predates all history known to mice.

The world of Mouse Guard is centered around a civilization of intelligent mice. They are not significantly anthropomorphized, beyond bipedal movement, verbal speech, simple clothing, and opposable thumbs. Think in terms of the characters in Secret of NIMH, but with longer individual life spans and no sign or legacy of humanity within their knowledge and histories.
Since you’re here, you likely want to know where to begin. Let’s start with basic steps for making a starting character for this campaign.
