Nine Worlds

Níu heimar — the Nine Worlds — are the nine realms of Norse cosmology held within the structure of Yggdrasil. Völuspá stanza 2 opens with the völva’s boast: “níu man ek heima” — “nine worlds I knew.” The complete list is never given in a single primary text, but the Prose Edda and the Poetic Edda together yield a coherent map.

The worlds

Ásgarðr — realm of the Æsir, the primary gods; seat of Valhöll, Glaðsheimr, and the individual halls of the major deities. Vanaheimr — realm of the Vanir, the fertility and nature gods; located differently from Ásgarðr after the ancient war between the two divine tribes. Miðgarðr — the “middle enclosure,” the world of humans, surrounded by the sea in which Jörmungandr lies coiled. Útgarðr or Jötunheimr — the outer world of the giants (jötnar), beyond the sea.

Álfheimr — realm of the light elves; Grímnismál stanza 5 says Freyr was given Álfheimr as a tooth-gift. Svartálfaheimr — realm of the dark elves (dwarfs in practice), where the great craftwork of the cosmos is forged: Mjölnir, Gungnir, Brísingamen, Gleipnir. Niðavellir (or Nidavellir) — sometimes distinguished as the realm of dwarfs. Niflheim — the world of primal ice and mist in the far north, the oldest world according to Gylfaginning; Hvergelmir, the primordial spring, lies here. Muspelheim — the world of primal fire in the south, ruled by Surtr, whose flames will destroy the current cosmos at Ragnarök. Hel (the realm, not the goddess) — beneath Niflheim, the destination of the dead who die of illness, age, and accident.

Nine as sacred number

Nine recurs throughout Norse cosmological thinking: nine nights of Odin’s ordeal, nine worlds, nine galdrar sung by Gróa for her son, nine in the structure of Ragnarök’s aftermath. It is not merely counting but a sacred completeness — the full cycle, three times three.
