He was outlawed for murdering a slave who had outdone him in hunting. With the help of Odin, 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 HugonesorHugas, 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 (or Siggi) is also mentioned in the prologue of the Prose Edda, where he is said to have ruled over Frakland (land of the Franks): "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."[2]
^Jesse L. Byock (c. 1990) suggested that the element sig ("victory"), which appears in the name of other members of the Völsung family - Sigmundr, Signý, Sigurðr, had to do with their special relationship with Odin, who was the god of victory (c.f. Sigtýr).
