The [[Poetic Edda]] contains two poems that mention Fáfnir. In the prose of the first, [[Reginsmál]], the eponymous figure [[Regin]] tells [[Sigurð]] that once Odin, Loki, and Hœnir went to the [[Waterfall|foss]] of the [[Dwarf (folklore)|dwarf]] [[Andvari]] who lived there in the form of a pike. In that water also lived Fáfnir and Regin's brother, [[Ótr]] who was eating a [[salmon]] on the bank, in the shape of an [[otter]]. Loki killed Ótr with a stone and the gods skinned him before seeking lodgings at the house of Hreiðmarr, the father of Fáfnir and his siblings. Seeing the otter skin, the family seized the gods and demanded that the gods fill and cover the skin in red gold as [[weregild]]. Loki caught Andvari using [[Rán]]'s net and exports the gold from him. In the poem, Andvari curses the gold which the gods give to Hreiðmarr. Fáfnir and Regin asked their father for some of the weregild but he refused, leading Fáfnir to kill him. As he dies, Hreiðmarr calls out to his daughters [[Lyngheiðr]] and [[Lofnheiðr]], but they take no action. Fáfnir then takes all the hoard, refusing to share it with his brother, and takes to Gnitaheath, where he took the shape of a [[Germanic dragon|worm]]. Along with Andvari's [[Rings in Germanic cultures|ring]], [[Andvaranaut]], the treasure here is described as including the Helm of fear ({{langx|non|[[ægishjálmr]]}}).{{sfn|Bellows|2004|loc=Reginsmál}}

In the second poem, [[Fáfnismál]], the prose prologue describes Sigurð and Regin going to Gnitaheath, where they find the track Fáfnir made as he crawled to the water to drink. Sigurð digs a trench across the path and hides in it. Later, Fáfnir leaves his hoard, blowing out [[atter]], and moves over Sigurð, who stabs him through the belly and into the heart. As the worm dies, the poem begins and consists of a conversation between him and Sigurð, in which Fáfnir asks for information about Sigurð, such as his name which he initially hides in riddles. Fáfnir then warns Sigurð against the gold, telling him that it will bring his death who responds, saying that a time will come for everyone to journey to [[Hel (location)|hell]]. The poem moves to Fáfnir teaching Sigurð lore, such as the identity of the [[Norns]] and the island where the gods will meet with [[Surtr]]. Fáfnir then warns Sigurð of the hoard again before the worm dies. Regin then meets with Sigurð where they quarrel over who deserves the praise for the death of Fáfnir.{{sfn|Bellows|2004|loc=Fáfnismál}} Notably here, Regin refers to his brother as an "ancient {{lang|non|[[jötunn]]}}".{{sfn|Motz|1982|p=73}} Regin then cuts out Fáfnir's heart with his sword [[Riðill]] and tells Sigurð to cook it for him while he sleeps. While cooking it on a spit, Sigurð tests to see if it is done but accidentally burns his finger in the process and sucks it, putting the heart's blood into his mouth. The blood allows Sigurð to understand seven birds who are talking nearby about how Regin is going to kill Sigurð and take the hoard for himself. Fearing they were right, Sigurð chops off Regin's head, eats Fáfnir's heart, then drinks the blood of both brothers. The following prose tells how Sigurð then followed Fáfnir's trail to his lair, which is described as a house dug down into the earth, the gates, gate posts and beams of which were all made of iron. Inside, Sigurð finds among the hoard the ægishjálmr, a golden mail coat and the sword [[Hrotti]], and loads all of it onto his horse Grani's back.{{sfn|Bellows|2004|loc=Fáfnismál}}
