A chapter of the Adeptus Astartes in Warhammer 40k. Clad in primarily grey power armor, they are known for their Norse/Viking aesthetic and frequent references to wolves. Because of the latter trait, many in the fandom often joke about them being Furries. They are one of the original Space Marine legions and their Primarch is Leman Russ, whose name would be used for the Imperial Guard's main battle tanks.
Their armor is colored in grey armor or blue, with the shoulder armor colored in other colors as yellow, red, white or black. They heavily utilize symbology related to the wolves and often have feral aspects, with long hair and long beards.
