The story of Ragnarok and the Apocalypse

In Norse mythology, Ragnarok is a series of apocalyptic events that will define the end of the world, where giants of frost and fire will together fight the gods in a final battle that will ultimately destroy the planet, submerging it under water. According to the legend, the world will resurface, the surviving and returning gods will meet, and the world will be repopulated by two human survivors.

 Brothers will fight and kill each other, sisters’ children will defile kinship. It is harsh in the world, whoredom rife —an axe age, a sword age —shields are riven— a wind age, a wolf age— before the world goes headlong. No man will have mercy on another.
Dronke (1997:19)
