Þorgrímr and Olof therefore elope and flee to Iceland, where they settle down and have two sons, Víglundr and Trausti, and a daughter, Helga.
As an adult, Víglundr Þorgrímsson begins courting Ketilríðr Hólmkelsdóttir, the daughter of his father's neighbour and friend Hólmkell.
This upsets her mother Þorbjǫrg and brothers Einarr and Jǫkull, who begin plotting against Víglundr.
Meanwhile in Norway, Ketill has married and has three children - two sons (Sigurðr & Gunnlaugr) and a daughter (Ingibjǫrg).
Hákon duly travels to Iceland and takes up lodging with Hólmkell, finding willing allies in the form of his host's sons Einarr & Jǫkull.
