Editing Fáfnir (section)

===General narrative===
Fáfnir's tale is attested in multiple medieval accounts which refer to a shared story with a general structure as follows:
* Fáfnir kills his father [[Hreiðmarr]] and takes his hoard of treasure that was often given as [[weregild]] by the gods [[Odin]], [[Loki]], and [[Hœnir]] for their unintended killing of Hreiðmarr's son [[Ótr]]. 
* Fáfnir kills his father and flees with the hoard and dwells in the wilderness, often at a place named Gnitaheath, where he becomes a [[Germanic dragon|worm or dragon]] ({{langx|non|ormr}} or {{lang|non|dreki}}). 
* Fáfnir's brother [[Regin]] forges a sword for Sigurð and convinces him to kill Fáfnir by hiding in a pit and striking him from below as the worm goes past, which [[Sigurð]] does. 
* Regin asks him to cook the worm's heart for him to eat. As Sigurð does this, he checks to see if it is cooked by touching it, whereupon he burns his finger and sucks it to cool it down. 
* The blood from the heart imparts to him the ability to understand birds, who he overhears talking about how Regin will betray him. Fearing this, Sigurð kills Regin and takes the treasure, loading it up on his horse [[Grani]].
