" In Muspell, at the edge of the flame, where the mist burns into light, where the land ends, stood Surtr, who existed before the gods. He stands there now...It is said that at Ragnarok, which is the end of the world, and only then, Surtr will leave his station. He will go forth from Muspell with his flaming sword and burn the world with fire, and one by one the gods will fall before him. "
