Volsung/Origin

Origin
In Norse mythology, Völsung was the son of Rerir, the great-grandson of Odin himself, and the eponymous ancestor of the ill-fortuned Völsung clan (Vǫlsungar), which includes the well known Norse hero Siguro. He was murdered by the Siggeir and later avenged by one of his sons, Sigmund, and his daughter Signy, who was married to Siggeir.
