[2] In Hrólfr Kraki's saga, Halfdan (Healfdene) had three children, the sons Helgi (Halga) and Hróarr (Hroðgar) and the daughter Signý.
Whereas Hróarr moved to Northumbria and married the king's daughter, Helgi (i.e. Halga) went to the Saxons wanting to woo their warlike queen Oluf.
She was, however, not interested and humiliated Helgi by shaving his head and covering him with tar, while he was asleep, and sending him back to his ship.
Yrsa was set to live as a shepherd, until she was 12 years old, when she met her father Helgi who fell in love with her, not knowing it was his daughter.
Learning that Helgi and Yrsa lived happily together, queen Oluf travelled to Denmark to tell her daughter the truth.
After some time, Bödvar Bjarki encouraged Hrólfr to go Uppsala to claim the gold that Aðils had taken from Helgi after the battle.
They were at first well received, but in his hall, Aðils did his best to stop Hrólfr with pit traps and hidden warriors who attacked the Danes.
Yrsa then provided her son with a silver drinking horn filled with gold and jewels and a famous ring, Svíagris.
Then she gave Hrólf and his men twelve of the Swedish king's best horses, and all the armour and provisions they needed.
Under the pretext that they would wait three years before paying the accumulated tribute at one time, Skuld assembled a large army which included strong warriors, criminals, elves and norns.
A fight started and like in the account found in Gesta Danorum, Bödvar Bjarki fought in the shape of a spirit bear until he was awakened by Hjalti.
