The Space Wolves, known in their own dialect of Juvjk as the Vlka Fenryka or "Wolves of Fenris," are one of the original 20 First Founding Space Marine Chapters, and were once led by their famed primarch, Leman Russ. Originally the VIth Legion of Astartes raised by the Emperor at the dawn of the Great Crusade, the Space Wolves are renowned for their anti-authoritarian ways and their embrace of their homeworld Fenris' savage barbarian culture as well as their extreme deviation from the Codex Astartes in the Chapter's organisation.
