The fim-bur wolf is said to be an ancient winter wolf that has achieved immortal life. The wolf often claims a large plot of land for itself and allows only a small pack of wolves that prove exceptionally strong to coincide within its territory. It will often attack anything that comes through its territory, only letting something pass if it sees it as too weak to be a challenge. Things it sees as to weak a challenge are not simply allowed to pass through, the fim-bur wolf will always maim, scar, or mark a creature any time passes through its territory. If a creature passes through more than three times without being deemed a challenge the fim-bur wolf will kill the creature. The fim-bur wolf will often take fingers from a humanoid creature as a mark, starting with the left index.
