flames, charges forward with his mouth wide open, his upper jaw reaching to the heavens, and his lower jaw touching the earth. At Fenrir's side, Jörmungandr sprays venom throughout the air and the sea. During all of this, the sky splits into two. From the split, the "sons of Muspell" ride forth. Surtr rides first, surrounded by flames, his sword brighter than the sun. High says that "Muspell's sons" will ride across Bifröst, described in as a rainbow bridge, and that the bridge will then break. The sons of Muspell (and their shining battle troop) advance to the field of Vígríðr, described as an expanse that reaches "a hundred leagues in each direction," where Fenrir, Jörmungandr, Loki (followed by "Hel's own"), and Hrym (accompanied by all frost ) join them. While this occurs, Heimdallr stands and blows the Gjallarhorn with all his might. The gods awaken at the sound, and they meet. Odin rides to Mímisbrunnr in search of counsel from Mímir. Yggdrasil shakes, and everything, everywhere fears. High relates that the Æsir and the Einherjar dress for war and head to the field. Odin, wearing a gold helmet and an intricate coat of mail, carries his spear Gungnir and rides before them. Odin advances against Fenrir, while Thor moves at his side, though Thor is unable to assist Odin because he has engaged Jörmungandr in combat. According to High, Freyr fights fiercely with Surtr, but falls because he lacks the sword he once gave to his messenger, Skírnir. The hound Garmr (described here as the "worst of monsters") breaks free from his bonds in front of Gnipahellir, and fights the god Týr, resulting in both of their deaths. Thor kills Jörmungandr but is poisoned by the serpent, and manages to walk only nine steps before falling to the earth dead. Fenrir swallows Odin, though immediately afterwards his son Víðarr kicks his foot into Fenrir's lower jaw, grips the upper jaw, and rips apart Fenrir's mouth, killing the great wolf. Loki fights Heimdallr and the two kill each other. Surtr covers the earth in fire, causing the entire world to burn. High quotes stanzas 46 to 47 of , and additionally stanza 18 of (the latter relating information about the battlefield Vígríðr). Gylfaginning chapters 52 and 53 At the beginning of chapter 52, Gangleri asks "what will be after heaven and earth and the whole world are burned? All the
