"Surtr moves from the south with the scathe of branches: there shines from his sword the sun of Gods of the Slain. Stone peaks clash, and troll wives take to the road. Warriors tread the path from Hel, and heaven breaks apart. Then is fulfilled Hlín's second sorrow, when Óðinn goes to fight with the wolf, and Beli's slayer, bright, against Surtr. Then shall Frigg's sweet friend fall." - Völuspá
