Swiftfang padded through the territory, after just being kicked out of RiverClan and the other clans for killing Reedstar ( made up RiverClan leader :P ) along with Silverthorn, though after the two had done it they went there separate ways, with Silverthorn becoming a loner and himself, searching for the ruthless BloodClan, finding himself wanting to be part of it now, killing had become something he liked.
Traditional RP will no longer allow non-canon breeds, but existing characters that are non-canon are grandfathered in. More information can be found here.
