The Way of the Ratling

This sourcebook details the Nezumi, a once-proud race struggling to survive in Rokugan. Living near the Kaiu Wall, in the Shinomen forests, and across the Shadowlands, they fight alongside the Crab against the Tainted creatures that have taken their lands. It includes rules for creating Nezumi player characters and tribes, along with their history, prominent tribes, language, alliances, and unique shamanic magic based on the power of names. The book also covers the Tattered Ear Tribe and the Nezumi’s relationships with the Crab and other clans.
