A Warrow of the Boskydells, and a resident of The Root in Woody Hollow. Perry is the great-grandson five times removed of Raven Greylock, the child of Tuckerby Underbank.

A professional historian, Peregrin was passionately interested in the story of his ancestor's adventures, and loved to imagine himself involved in an adventure as well. When Anval, Borin and Kian revealed their quest to reclaim the dwarvish mine of Kraggen-Cor, he was eager to participate, despite the misgivings of his handwarrow, Cotton Buckleburr.

Traumatized by the death and mayhem that he saw, Perry acquired a new appreciation for peace. He later married Holly Northcolt and they had four children: Dando, Petal, Silver and Pippen.
