Hervarar saga ok Heidhreks is a fornaldarsaga from the 13th century using material from an older saga. It contains matter from wars between Goths and Huns.
The saga deals with the shieldmaiden Hervor and her son Heidrek, the king of Reidgotaland. Between his sons Angantyr and Hlod, there is a great battle about their father's heritage and Hlod is aided by the Huns. However, Hlod is defeated and killed.
In the end, the saga relates that Angantyr, had the son Heidhrekr Ulfhamr who was king of Reidgotaland for a long time. Heidhrekr's daughter was Hildr and she had the son Halfdan the Kind. Halfdan the Kind was the father of Ivar Vidfamne. After Ivar Vidfamne, the saga recites the line of Swedish kings to the certainly historical Philip Halstensson (see Swedish semi-legendary kings).

Text in Old Norse (http://www.snerpa.is/net/forn/hervar.htm)
Halfdan's cousin Duke Eirik Bloodspear, a handsome chieftain, warrior technician and sub commander of Halfdan's armies, Thorvald Blood Dancer the Wolf-shirt Berserk, Dag Jotunn, Hring's father who is 8 feet tall and a true giant, Dag's wife Alvi who is a warrior and is a giant 7 foot tall woman in her own right.
Halfdan and his men win the siege in the mountains, and chase the unlucky King Eystein out of his own hereditary province, forcing him to seek help from the wild northerners, who are more old-fashioned and lawless than the seagoing and relatively cosmopolitan Halfdan and his allies.
Halfdan takes a fancy to a captive, (an Egyptian slave girl who had been taken by Ulf and his men on one of their raids in Germany where she was a life-long slave).
