Ottar's sons Eanmund and Eadgils (Adils) had to flee to Geatland and seek refuge with the Geatish king Heardred.
In order to avenge his king and kinsman, Beowulf decided to help Eadgils gain the throne of Sweden.
Snorri relates that much is told about this event in the saga of the Sköldungs, and that Adils took Hrafn (Raven), Áli's horse.
Adils would become a famous king of whom much is told in the legends of Hrólf Kraki and in the Danish Gesta Danorum.
Many instances of boar-crested helmets have been found in extant examples, notably in the burial mounds of Vendel, Valsgärde and Uppsala.
