Norse cosmology counts nine realms, all bound together by the branches and roots of Yggdrasil: Asgard, Vanaheim, Alfheim, Midgard, Jotunheim, Muspelheim, Niflheim, Svartalfheim, and Helheim. This page is the atlas entry point, a brief survey of all nine before you follow any single one deeper.
Nine worlds on one tree
The count of nine comes from Voluspa's second stanza, where a seeress recalls nine worlds she remembers from before the beginning of things. The Prose Edda later fills most of these in by name, tying each one to a branch or root of Yggdrasil, the immense ash that gives every realm its place. Bifrost, the burning bridge, is the one crossing built specifically to join two of them, Midgard and Asgard, though most of the nine are reached by other paths entirely.
The nine realms at a glance
Each realm has its own inhabitants and its own character within the wider structure.
| Realm | Old Norse | Inhabitants |
|---|---|---|
| Asgard | Ásgarðr | The Aesir gods, led by Odin |
| Vanaheim | Vanaheimr | The Vanir gods, tied to fertility and the sea |
| Alfheim | Álfheimr | The light elves, the Ljósálfar |
| Midgard | Miðgarðr | Humans |
| Jotunheim | Jötunheimr | The giants, the jötnar |
| Muspelheim | Múspellsheimr | The fire-giants, ruled by Surt |
| Niflheim | Niflheimr | Primordial ice and mist, feeding Hvergelmir's rivers |
| Svartalfheim | Svartálfaheimr | The dwarves |
| Helheim | Hel | The dead who die of sickness or old age, ruled by Hel |
The realm of gods and their kin
Asgard is the high fortress of the Aesir, Odin's own realm and the seat of Valhalla, reached from Midgard only across Bifrost. Nearby stand two smaller realms tied to it by marriage and gift: Vanaheim, home of the Vanir gods such as Njord, Freyr, and Freyja before they joined the Aesir, and Alfheim, given to Freyr as a gift and home to the luminous light elves.
Midgard and the giants' wilds
Midgard, the realm of humans, sits at the center of the nine worlds, ringed by an ocean where the serpent Jormungandr grips its own tail. Beyond its borders lies Jotunheim, a cold and mountainous wilderness home to the jötnar, the giants who test the gods constantly and are, through marriage, sometimes their kin.
