About Heidrek
Heidrek or Heiðrekr is one of the main characters in the cycle about the magic sword Tyrfing. He appears in the Hervarar saga, and probably also in Widsith, together with his sons Angantyr and Hlöð, and Hlöð's mother Sifka. The etymology is heiðr, meaning "honour", and rekr, meaning "ruler, king".
