In Norse mythology, Surtr (the black one) will lead Muspelheim's sons to Ragnarök. He will "ride in front, and both before and behind him there will be burning fire [...] Light will shine from [his sword] more brightly than from the sun." "In Surtur's grasp the Sword of Revenge blazes, adding a blood red colour to the twilight of the whole world." He will defeat all of the [remaining] Æsir, his fire will burn all of the heavens and the earth, save for the few that sought refuge in the woods Hoddmímis holt.
