A version of the legend of Starkad can be found in the prologue of the U-version of Hervarar saga, and in a shortened form in the H-version of the Hauksbók.
In this version a Starkad Ala-Warrior lived in northern Norway at the waterfalls of Alufoss. He descended from the giants known as the þursar (jotuns), and his father's name was Storkvid. Starkad was very much a jotun himself and had eight arms, but he was betrothed to a girl named Ogn Elf-burst. One day, when Starkad had gone north across the Élivágar, another giant named Hergrim kidnapped Ogn. Starkad challenged Hergrim to a holmgang, a duel. Starkad used four swords at the same time and slew Hergrim. Ogn did not wish to be Starkad's wife and committed suicide by stabbing herself with a sword. Starkad took everything Hergrimr owned including his son Grimr.
Álfhildr was the daughter of king Álfr of Álfheim (modern Bohuslän) and like the people of Álfheim, she was very beautiful. One autumn, king Álfr performed the Dísablót, a sacrifice to the goddesses, and Álfhildr took part in it. As she was reddening the horgr (altar) with blood, Starkad kidnapped her. King Álfr called on the god Thor to help him rescue his daughter. Thor granted his wish by killing Starkad and rescuing the girl.
