Ragnarok

Ragnarok was the time when all the visible creation, the gods of Valhalla and Niffleheim, the inhabitants of Jotunheim, Alfheim and Midgard, with their habitations would be destroyed. Some things would happen first to warn of the destruction to come.... First will come a triple winter, during which snow will fall from the four corners of the heavens, the frost will be very severe, the wind piercing, the weather tempestuous, and the sun will impart no gladness. Three such winters will pass away without being tempered by a single summer. Three other similar winters will then follow, during which war and discord will spread over the universe. The earth itself will be frightened and begin to tremble, the sea leave its basin, the heavens tear asunder, and men parish in great numbers, and the eagles of the air feast upon their still quivering bodies. The wolf Fenris will now break his bands, the Midgard serpent rise out of her bed in the sea, and Loki, released from his bonds, will join the enemies of the gods. Amidst the general devastation the sons of Muspelheim will rush forth under their leader Surtur, before and behind whom are flames and burning fire. Onward they ride over Bifrost, the rainbow bridge, which breaks under the horses' hooves. But they, disregarding its fall, direct their course to the battlefield called Vigrid. Thither also repair the wolf Fenris, the Midgard serpent, Loki with all the followers of Hela, and the Frost giants.

Heimdall now stands up and sounds the Giallar horn to assemble the gods and heroes for contest. The gods advance, led by Odin, who engages the wolf Fenris, but falls victim to the monster who is si slain by Vidar, Odin's son. Thor gains great renown by killing the Midgard serpent, but recoils and falls dead, suffocated with the venom which the dying monster vomits over him. Loki and Heimdall meet and fight till they are both slain. The gods and their enemies having fallen in battle, Surtur, who has killed Frey, darts fire and flames over the world, and the whole universe is burned up. The sun becomes dim, the earth sinks into the ocean, the stars fall from heaven, and time is no more.

After this Alfadur will cause a new heaven and a new earth to rise out of the sea. The new earth filled with abundant supplies will be spontaneously produce its fruits without labor or care. Wickedness and misery will no more be known but the gods and men will live happily together.
