Sigi was said to be a son of Odin. One day, he went out hunting together with a slave named Bredi. When Bredi returned with a far greater kill, Sigi angered and in his rage he slew the man. For this act he was decreed an outlaw and was banished from his home. With the help of Odin, he was guided to some warships and Sigi took up raiding. Through the success of this he managed to become a mighty ruler, ruling over a land known as Hunland.
