After a while Frotho was killed through treachery by a Saxon named Swerting (Swertingus). Frotho's son Ingild (Ingellus) lived a wanton life and married one of Swerting's daughters. This angered Starkad so much that he enlisted at the Swedish king Halfdan's (Haldanus) court instead. However, when he learnt that Helga, Ingild's sister, was about to marry a lowly goldsmith, Starkad appeared in disguise and castrated the goldsmith. He gave Helga a slap on her face and lambasted her. Then he returned to Sweden and king Halfdan.
