The Lost Bone of the Werewolf was a cursed bone that became hairy when it was exposed to the full moon. Sometime around the year 2351, Fangster managed to locate The Lost Bone of the Werewolf, which was burried in the wasteland not far from the Arch. By replacing a specific bone located in the side of the Arch with the Lost Bone of the Werewolf, Fangster activated the Arch. This way, when a series of dogs that Fangster had captured earlier passed through the Arch one by one, they turned into 'Werewolf Slaves' that lived to do Fangsters bidding. Eddie Spenser Jr. also passed through the Arch and began having Werewolf features soon thereafter.
