In the Icelandic Eddas Surtur is the leader of the fire giants in the south, the ruler of Muspel, the realm of fire. He was married to Sinmore. In Snorry Stuluson's Edda (1179-1241): "Surtur is the one so named who stands on Múspell's border, guarding the land. His sword is flaming and as the world ends he will go out, make war against and triumph over the gods. And he will burn the whole world with fire" (Gimlé Gylkaginning, iv).
