Voluspa opens with Odin raising a dead seeress and pressing her to speak. What follows is her account, moving from the world's creation through its history to its end: three years of unbroken winter, the wolf Skoll swallowing the sun, the stars falling from the sky, the world tree Yggdrasil shaking, and the ship Naglfar, built from dead men's fingernails, setting out. The fire giant Surt crosses the rainbow bridge Bifrost and breaks it behind him. In the battle that follows, Odin is killed by the wolf Fenrir and avenged by his son Vidar; Thor kills the Midgard serpent and dies of its venom; Freyr falls to Surt; Heimdall and Loki kill each other. The earth sinks into the sea.
The poem does not end there. A new earth rises from the water, green and unsown, and an eagle fishes over its waterfalls. Baldr, killed earlier in the mythic cycle, returns from the dead alongside his killer Hodr, and the surviving gods, Vidar, Vali and others, meet again on the plain of Idavoll to remember what came before. Two humans, Lif and Lifthrasir, who hid through the destruction inside Yggdrasil, emerge to repopulate the new world.
This is presented throughout as the seeress speaking in her own voice about what she sees, "I remember" and "I see", not as a myth narrated about the gods in the third person. Old Norse kept a specific vocabulary for this kind of sight, and the volva who performed it was a recognised, if ambivalent, ritual specialist rather than simply a poetic device.
