[7-8]: Hervǫr goes on to have two sons, the good-natured and popular Angantýr and the trouble-making Heiðrekr, who is sent away to be fostered. There is no indication of sibling ‘contention’ until Heiðrekr kills his brother with an indiscriminately-thrown stone. Tyrfingr is not involved in that trouble. Tolkien (Heiðr 1960, xi) suggests a now-lost account of strife between them may have once existed. Hervǫr’s grandsons, on the other hand, the sons of Heiðrekr, contend over their inheritance in what becomes a battle between nations, resulting in one brother slaying the other (cf. Schück 1918, 79; Heiðr 1960, xi and n. 3).
