Summary
The nine worlds hang in the branches and coil around the roots of Yggdrasil. From the fortress of the gods to the realm of the dead, from fire to ice, each world is home to different beings and forces. This episode maps the entire Norse cosmos—a geography essential for understanding every story that follows.
The Nine Worlds
Ásgarðr (AWS-garth-r): The stronghold of the Æsir, the primary tribe of gods. Connected to Miðgarðr by the burning rainbow bridge Bifröst.
Vanaheimr (VAN-ah-haym): The home of the Vanir, the secondary tribe of gods associated with fertility, nature, and the magical craft of seiðr.
Álfheimr (AHLF-haym): The realm of the light elves (ljósálfar), “fairer than the sun to look at.” A realm of natural fertility and ancestor spirits.
Miðgarðr (MITH-garth-r): The middle world, the human realm. Built from Ymir’s flesh and protected by walls made from his eyebrows. Surrounded by the ocean in which the world serpent Jörmungandr lies.
Muspellsheimr (MOO-spell-haym-r): The primordial realm of fire. Surtr, the fire giant, waits at its border with a flaming sword. Will invade at Ragnarök.
Niflheimr (NIV-ul-haym): The primordial realm of ice and mist, older than creation itself. The spring Hvergelmir flows here, and Níðhöggr gnaws at the roots of Yggdrasil.
Jötunheimr / Útgarðr (YUR-tun-haym / OOT-garth-r): The realm of the giants, the jötnar. The “outer enclosure” beyond the walls of Miðgarðr. A place of ancient wisdom and natural force.
Svartálfaheimr / Niðavellir (SVART-ahl-fah-haym / NEETH-ah-vel-eer): The underground realm of the dark elves (dökkálfar) and dwarfs (dvergar). The greatest craftsmen in the cosmos forge the gods’ weapons here.
Hel (HEHL): The realm of the dead, ruled by the goddess Hel. The default afterlife for those who die of illness, old age, or accident—not punishment, but grey and quiet.
Key Concepts
Bifröst (BIV-rust): The burning rainbow bridge connecting Miðgarðr to Ásgarðr. The gods’ daily commute. Will break at Ragnarök under the weight of the sons of Múspell.
Heimdallr (HAYM-dal-r): The watchman of the gods, stationed at Bifröst. Needs less sleep than a bird. Can see and hear across all the worlds. Will sound Gjallarhorn at Ragnarök.
Jörmungandr (YUR-mun-gand-r): The world serpent, so vast it encircles the entire world and bites its own tail. Lies in the ocean surrounding Miðgarðr.

What Listeners Will Learn
The Norse cosmos is not a hierarchy but an ecosystem. Everything is connected, permeable, and mutually dependent. The borders between realms are real but crossable. The gods regularly visit the giants. Enemies are also kin. And everything is slowly moving toward a final collision—Ragnarök—when the careful balance finally breaks.
This is the map we’ll explore for the rest of Season 1 and beyond.
