===Völsunga saga===
When [[Loki]] mistakenly kills [[Ótr]], Hreiðmarr demands to be repaid with the amount of gold it takes to fill [[Ótr]]'s skin and cover the outside. Loki takes this gold from the dwarf [[Andvari]], who curses it and especially the ring [[Andvaranaut]]. Fáfnir kills his father for this gold, but eventually becomes a greedy [[Germanic dragon|worm or dragon]]. Reginn gets none of the gold, but he becomes smith to the king and foster father to [[Sigurð]], teaching him many languages as well as sports, chess, and runes.<ref>{{Harvnb|Byock|1990|p=56}}</ref>

Reginn had all wisdom and deftness of hand. Of his two brothers, he has the ability to work iron as well as silver and gold and he makes many beautiful and useful things. While Sigurð is living with Reginn, Reginn challenges Sigurð's respect in the kingdom. He tells Sigurð to ask for a horse. Sigurð asks the advice of an old man in the forest, and the old man shows him how to get a horse that is descended from [[Sleipnir]], the eight-legged horse of [[Odin]].<ref>{{Harvnb|Byock|1990|pp=55–57}}</ref> Reginn continues to goad Sigurð, this time into killing Reginn's brother Fáfnir. He offers to make a sword for Sigurð, but Sigurð broke every sword Reginn forged for him by striking at an anvil. Sigurð retrieves the broken pieces of his father [[Sigmund]]'s sword, [[Gram (mythology)|Gram]], and brings them to Reginn. Reginn repairs the sword and gives it back to Sigurð. When Sigurð again tests the blade by striking the anvil, the anvil this time is split down to its base, and when Sigurð places a piece of wool in a stream, the current pushing the wool against the sword was enough to cause the blade to cut it in two. Sigurð is finally very pleased with Reginn's repaired weapon.<ref>{{Harvnb|Byock|1990|pp=59–60}}</ref>

After using [[Gram (mythology)|Gram]] to kill Fáfnir, Sigurð returns to ask Reginn what to do. Reginn instructs him to roast the heart of his brother, and let him eat it. As juice from the dragon's heart foams out, Sigurð tests it with his finger to see if it is done cooking. As the blood touches his tongue, [[Sigurð]] understands the speech of birds, who warn him that Reginn intends to kill him. Before he lets any of this happen, Sigurð first wields [[Gram (mythology)|Gram]] and cuts off Reginn's head.<ref>{{Harvnb|Byock|1990|pp=65–66}}</ref>

===Þiðreks saga===
The Norwegian ''[[Þiðreks saga]]'' relates a slightly different tale, with Reginn as the dragon and [[Mimir]] as his brother and foster father to Sigurð.{{citation needed|date=April 2018}}
