Ragnarök

Ragnarök means roughly "the doom of the powers" or "the fate of the gods." In the Old Norse sources it is not a single afternoon of destruction but a sequence: omens, a long winter, the breaking of bonds, a battle, and a remaking. The two main accounts are the poem Völuspá ("The Seeress's Prophecy") in the Poetic Edda, spoken by a dead prophetess, and the prose retelling in Snorri Sturluson's Gylfaginning ("The Beguiling of Gylfi") in the thirteenth century.

The signs

Before the end comes the Fimbulwinter: three winters with no summer between them, a world of snow and sharpened winds from every direction. Brother turns on brother for gain; the bonds of kinship and oath break. This is the moral weather of the end as much as the physical one.

Then the signs multiply. The wolf Sköll swallows the sun; his brother Hati swallows the moon, and the stars are torn from the sky. The earth shakes so hard that mountains fall and all bonds break: the great wolf Fenrir tears free of his chains, the world-serpent Jörmungandr thrashes in the sea, and the ship Naglfar, built from the nails of the dead, breaks loose to carry the giants to battle. Heimdall, watchman of the gods, blows the horn Gjallarhorn to wake the worlds; Odin rides to consult the severed head of Mímir for counsel.

The battle

At the plain of Vigrid the armies meet. The details are the most remembered part of the story:

• Odin rides against Fenrir and is swallowed whole. His son Víðarr kills the wolf by planting one foot on its lower jaw and tearing its mouth apart.
• Thor fights the Midgard Serpent Jörmungandr and kills it with his hammer Mjölnir, then takes nine steps and dies of the serpent's venom.
• The cycle of vengeance closes: Odin, to secure a son who can punish the blind god Höðr for Baldr's death, mates with the giantess Rindr and engenders Váli, who grows to full manhood in a single day and kills Höðr.
• Freyr falls to the fire-giant Surtr, having given away his sword for love.
• Heimdall and Loki kill each other. Týr and the hell-hound Garm do the same.
• Surtr advances and flings fire over the earth, "so that the flames reach the sky."

The sun darkens, the earth sinks into the sea, steam rises, and the high fires meet heaven.

What rises after

Ragnarök is an end, but not the end. The Völuspá turns from destruction to a new green earth that rises from the water, fairer than before. The surviving gods gather on the plain of Iðavöllr: sons of the old gods return, including Baldr and Höðr, released from the dead. A new sun, the daughter of the old, walks the sky.

Crucially, humanity continues. Two people, Líf and Lífthrasir ("Life" and "Life's Desire"), have been hidden in the wood Hoddmímis holt through the fire and flood, and from them the earth is repopulated. An eagle still hunts by a renewed river. The poem ends with a glimpse of a hall roofed in gold and a figure who judges the dead, and then, in the best manuscripts, a strange last stanza that some scholars read as a later Christian addition.

Why it matters

Ragnarök sits at the meeting point of two end-of-the-world shapes. It has the trappings of a final battle and a moral climax, like the linear eschatologies of the south, but it resolves into renewal, like a Kali Yuga cycle. The gods lose, and the world wins. That combination, a heroic defeat followed by a quiet repopulation, is part of why the story has outlasted the religion that told it. The spread of the expectation across the North, ahead of the manuscripts, is described under Denmark, Norway and Iceland. The Icelandic manuscripts that hold it are the reason we have it whole.
