Ragnarok ("Doom of the Gods"), also called Gotterdammerung means the end of the cosmos. Ragnarok will be preceded by Fimbulvetr, the winter of winters. Three such winters will follow each other with no summers in between. Conflicts and feuds will break out, even between families, and all moral will disappear. This is the beginning of the end.

The wolf Sköll will finally devour the sun, and his brother Hati will eat the moon, plunging the earth into darkness. The stars will vanish from the sky. The cock Fjalar will crow to the giants and the golden cock Gullinkambi will crow to the gods. A third cock will raise the dead.

Earthquakes will shudder the earth, and every bond and fetter will burst, freeing the terrible wolf Fenrir. The sea will rear up because Jormungand, the Midgard Serpent, is twisting and writhing in fury, making his way toward the land. With every breath, Jormungand will stain the soil and the sky with his poison. The waves caused by the serpent's emerging will set free the ship Naglfar, and with the giant Hymir as their commander, the giants will sail towards the battlefield. From the realm of the dead a second ship will set sail, and this ship carries the inhabitants of hel, with Loki as their helmsman. The fire giants, led by the giant Surt, will leave Muspellheim in the south to join against the gods. Surt, carrying a sword that blazes like the sun itself, will scorch the earth.

Meanwhile, Heimdall will sound his horn, gjallahorn, calling Odin's sons and heroes (the Einheriar) to the battlefield. From all the corners of the world, gods, giants, dwarves, demons and elves will ride towards the huge plain of Vigond ("battle shaker") were the last battle will be fought. Odin will engage Fenris in battleand Thor will attack Jormungand. Thor will be victorious, but the serpent's poison will kill the god of thunder. Surt will seek out the swordless Freyr, who will quickly succumb to the giant. The one-handed Tyr will fight the monstrous hound Garm and they will kill each other. Loki and Heimdall, age-old enemies, will meet for a final time, and neither will survive their encounter. The fight between Odin and Fenris will rage for a long time, but finally Fenris will seize Odin, and swallow him. Odin's son Vidar will at once leap towards the wolf, and kill him with his bear hands, ripping the wolf's jaws apart.

Then Surt will fling fire in every direction. The nine worlds and the Tree of Life will burn, and friends and foes alike will perish. The earth will then sink into the sea.

After the destruction, a new idyllic world will arise from the sea and this new world will be filled with abundant supplies. Some of the gods will survive, others will be reborn. Wickedness and misery will no longer exist and gods and men will live happily together. The only humans who will survive this destruction are Lif ("life") and Liftrasir ("eager for life") because they hid themselves in Hodmimir's Forest, the forest that the flaming sword of the fire-giant Surt cannot destroy. There they sleep through the destruction of the earth and when they awaken, they will find the earth is green and verdant again. Lif and Liftrasir will become the progenitors of an new race of humans, and their descendants will inhabit this world.

When the world arises from its ashes, both Balder and Hod will be reborn.

Ragnarök does not mean "Twilight of the Gods"; that phrase is the result of a famous mistranslation. "Ragnarökr" or "Ragnarøkr" means "doom of the powers" or "destruction of the powers" (where "powers" means "gods").
