As a result, when the Æsir refused to release him, he bit off Týr's hand at a location 'now called the wolf-joint' (the wrist), causing Týr to be one-handed and 'not considered to be a promoter of settlements between people.' Gylfaginning chapter 34 This was done at Fenrir's own request because he did not trust that the Æsir would let him go. High says that one example of Týr's bravery is that when the Æsir were luring Fenrir (referred to here as Fenrisúlfr) to place the fetter Gleipnir on the wolf, Týr placed his hand within the wolf's mouth as a pledge. Fenrir is first mentioned in prose in chapter 25, where the enthroned figure of High tells Gangleri (described as King Gylfi in disguise) about the god Týr.

In chapter 13 of the Prose Edda book Gylfaginning, Fenrir is first mentioned in a stanza quoted from Völuspá. In the Prose Edda, Fenrir is mentioned in three books: Gylfaginning, Skáldskaparmál and Háttatal. Fenrir has been the subject of artistic depictions and he appears in literature. Depictions of Fenrir have been identified on various objects and scholarly theories have been proposed regarding Fenrir's relation to other canine beings in Norse mythology. In the Prose Edda, additional information is given about Fenrir, including that, due to the gods' knowledge of prophecies foretelling great trouble from Fenrir and his rapid growth, the gods bound him and as a result Fenrir bit off the right hand of the god Týr. In both the Poetic Edda and Prose Edda, Fenrir is the father of the wolves Sköll and Hati Hróðvitnisson, is a son of Loki and is foretold to kill the god Odin during the events of Ragnarök, but will in turn be killed by Odin's son Víðarr.

He is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources, and the Prose Edda and Heimskringla, written in the 13th century by Snorri Sturluson.

Fenrir, together with Hel and the World Serpent, is a child of Loki and giantess Angrboða. Fenrir ( Old Norse: ' fen-dweller') or Fenrisúlfr (O.N.: 'Fenrir's wolf', often translated 'Fenris-wolf'), also referred to as Hróðvitnir (O.N.: 'fame-wolf') and Vánagandr (O.N.: 'monster of the Ván'), or Vanargand, is a wolf in Norse mythology.
