Sigi

Sigi (or Siggi) is the forefather of the Vǫlsungr lineage. He is said to be one of the sons of Óðinn in the Vǫlsunga saga and Nafnaþulur both. He has a son named Rerir.

He was outlawed for murdering a thrall named Breði who had outdone him in hunting. With the help of Óðinn, Sigi fled from the land and led successful raids, so much so that he became king of Húnaland, a country name referring both to the territories of the Franks, also known as the Hugones or Hugas, and the territories of the Huns. In his old age, he was killed by his wife's brothers who seized his kingdom. His son Rerir avenged him.

Sigi is also mentioned in the prologue of the Prose Edda, where he is said to have ruled over Frakland: "Odin's third son is named Sigi, his son Rerir. These the forefathers ruled over what is now called Frankland; and thence is descended the house known as Völsungs."
