Uramasa
In the land of Skyrim, there were two Redguard brothers. The oldest, Naclan and the youngest, Jonrk. They've always had to compete, until one day, they took their rivalry too far that lead them to depart on separate paths.
Up in the north lies Castle Volkihar. Inside housed a clan of vampires, lead by the Vampire Lord, Harkon. In the City of Whiterun, housed The companions. Warrior heroes by day, werewolves by night. Then there was the Dawnguard, famous yet vaguely known vampire hunters.
Lord Harkon, along his other vampire thralls aim to eternally block the sun so that they may forever roam the Earth, conquering every inch of land within their reach. The Dawngaurd knew of this, but with their dwindling numbers and the vampires' ever increasing, they enlist the help of the companions.
A war is waiting, the brothers will meet on the battlefield. Will they set aside their rivalry to save the world? Or will it be everyone's downfall?
