[1] It tells of Hávarðr, who had been a great Viking in his youth and was wounded in Scotland and has walked with a limp ever since.
After gaining much popularity in the district for his sheep gathering skills and fights with the undead, Hávarðr's son Óláfr is killed by the jealous Þorbjörn.
After a few years of inaction attributed to his old age, Hávarðr sets out to avenge his son with newly found vigour.
In a key scene of the saga, Hávarðr seeks revenge and with a group of men attempts to confront Þorbjörn.
Þorbjörn then drops the slippery rock on himself and Hávarðr easily slays him.
