Grimm's law
Heidrek became king of the Goths. During a voyage, Heidrek camped at the Carpathians (Harvaða fjöllum, cf. Grimm's law). He was accompanied by eight mounted thralls, who eventually entered his tent and slew him in his sleep, the third and final of Tyrfing's evil deeds. Heidrek's son, also named Angantyr (the third), caught and killed the thralls and reclaimed the magic sword, finally satisfying the dwarves' curse.
