Capture of Thor
After Surtur captured Thor in Muspelheim, the God of Thunder broke out of his chains and began fighting Surtur and his minions. Surtur wielded the Twilight Sword and used its fiery power against Thor, but Thor withstood the assault thanks to Mjølnir and eventually defeated Surtur. The Twilight Sword vanished as the power of the deceased Surtur was absorbed into his crown.
When Loki resurrected Surtur with the Eternal Flame, the Twilight Sword reappeared in the same time than the mighty Fire Demon. Surtur brandished the now giant Twilight Sword once again and used it to spread chaos and destruction across Asgard. When Hela tried to retaliate, Surtur remained unaffected by her assaults and shove the Twilight Sword down deep to the core of Asgard, causing the planet to explode and fulfilling the prophecies of Ragnarök.
- In the comics, the Twilight Sword was created by Surtur exploding the home galaxy of the Korbinites intended to set the universe afire. It was later used as a power source by Loki and Morgan Le Fay.
