The two brothers both became kings of Denmark, and Roas married the daughter of the king of England. Helgo, on the other hand, raped Olava, the queen of the Saxons, and she bore a daughter named Yrsa. The girl later married king Adillus (Eadgils), the king of Sweden. Some years later, Helgo attacked Sweden and captured Yrsa, whom he raped. His daughter bore him the son Rolfo (Hroðulf). After a few years, Yrsa's mother, Queen Olava, came to visit her and told her that Helgo was her own father. Yrsa returned to Adillus, leaving her son behind. Helgo died when Rolfo was eight years old, and Rolfo succeeded him. Not much later, Roas was killed by his half-brothers Rærecus and Frodo, whereupon Rolfo became the sole king of Denmark.
