It tells that young Starkad was raised at the court of Harald, the king of Agder, together with Harald's son Vikar. One day, Herþjófr, the king of Hordaland, made a raid and killed king Harald. He also took Vikar hostage to ensure the loyalty of the people of Agder. When Vikar had grown up, he assembled a warband, including Starkad and avenged his father by killing Herþjófr with thirty of his warriors. Vikar was then king of Agder, Hordaland, and Hardanger.
