He is destined to be slain bye Sigurd. Fafnir, son of Hreidmar, with a swollen smithing arm and a ravenous hunger for violence, both of which are eclipsed by his avarice. Loki the Trickster God, stuffed the pelt to bursting with the cursed treasure of Andvarri. Hreidmar, unaware of the maligned hoard, greedily exchanged the Aesir for the wealth. That night, curling his powerful arm, Fafnir strangled his father and vanished into night with the cursed gold. Twisted he became a greedy Dragon.
