The Space Wolves, known in their own dialect as the Vlka Fenryka or "Wolves of Fenris", are one of the original 20 First Founding Space Marine Legions, and were once led by their famed Primarch, Leman Russ.
The Space Wolves are notorious throughout the Imperium for their ferocity in battle and they are generally considered the greatest warriors of the loyalist Astartes Chapters.
The Space Wolves homeworld is Fenris, a death world that lies in the galactic north of Segmentum Solar. It is a relentless world of fire and ice, ravaged by the extremes of climate all year round. For the majority of its year the planet is blanketed by an extreme winter.
