Glossary & Pronunciation Guide

The stronghold of the Æsir, the primary tribe of gods. Ásgarðr is protected by walls and connected to Miðgarðr by the burning rainbow bridge Bifröst.

Inside Ásgarðr lie the golden halls: Bilskírnir (Thor’s hall with 540 rooms), Glaðsheimr (the hall of the gods), and Hliðskjálf (Odin’s high seat, from which he can see into all the worlds).

The Æsir govern from Ásgarðr, but they are not isolated. Odin regularly travels to other realms seeking knowledge. Giants enter Ásgarðr as guests (and sometimes as threats). The stronghold is the inner fortress of the cosmos, but its borders are not sealed.

“The trembling path” or “the shimmering path.” The burning rainbow bridge connecting Miðgarðr to Ásgarðr. The red color comes from actual fire—the bridge is on fire, and that fire is its defence against the frost giants.

The gods ride across Bifröst each day to hold court at the Well of Urðr. It is the strongest bridge ever made, and yet it will break.

At Ragnarök, the sons of Múspell will ride across Bifröst, and the strongest thing the gods ever made will shatter under their march. This reminds us of a core truth in Norse mythology: nothing the gods build is permanent. Everything will break.

The primordial void—not empty, but pregnant with potential. The space where creation began, separating Niflheimr (the ice realm) from Múspellsheimr (the fire realm).

The name carries the sense of sacred power. Ginn- refers to a kind of charged potential, while the “gap” is both a physical space and a moment suspended between opposing forces. When ice and fire converged in Ginnungagap, the meeting produced Ymir, the first living being.

Ginnungagap is where ice melts, where venom quickens, and where creation becomes possible through accident rather than intention.

“The outer enclosure.” The realm of the giants (jötnar), the primal forces of nature and chaos. Calling the giants “villains” misses their role—they are older than the gods, born from the sweat of the first giant, and often possess the kind of wisdom the Æsir must travel to gain.

Odin regularly journeys to Jötunheimr, engaging in contests of knowledge with giant kings. The boundaries between god and giant are political, not biological—many gods have giant blood, and many giants are powerful and wise.

“Middle enclosure.” The human world, built from the flesh of Ymir and protected by walls made from his eyebrows. Miðgarðr is where we live—in the middle of a murdered giant’s body, kept safe behind a fence made from his face.

The word survives in Old English as middangeard, which is the origin of Tolkien’s “Middle-earth.”

Miðgarðr is surrounded by a vast ocean in which the world serpent Jörmungandr lies coiled, so enormous it encircles the entire world and bites its own tail. Whoever stands in Miðgarðr, there is a serpent larger than the world beneath the sea, just off the edge of the land.

The primordial realm of fire, the counterforce to Niflheimr. Múspellsheimr has existed since before creation, and at its border stands Surtr, a fire giant with a flaming sword, patient and immobile.

Múspell is one of the oldest words in Germanic mythology, appearing in the Old Saxon Heliand as referring to the end of the world. The name reaches back to a time when Norse, English, German, and Gothic peoples shared a common language and a common terror: fire at the end of all things.

“Malice Striker.” A dragon or serpent coiled at the base of Yggdrasil’s root extending into Niflheimr. It gnaws endlessly at the wood, attacking the foundations of the cosmos from below.

Níðhöggr is not merely destructive. It also devours the bodies of oathbreakers and murderers at Náströnd, the Corpse Shore. It is destruction with moral dimension—the thing that tears the world apart is also the thing that punishes those who tear the social order apart.

The world of mist and ice, one of the two primordial realms that existed before creation. Older than the gods, older than time, Niflheimr was always there—a condition as much as a place.

At its heart flows Hvergelmir, the bubbling cauldron, from which eleven rivers called the Élivágar pour north into the void. The dragon Níðhöggr gnaws at the root of Yggdrasil that extends here.

Niflheimr is not merely a landscape. It is the cold, the dark, the fog that existed before anything else and will remain after everything ends. In some traditions, the realm of the dead (Hel) overlaps with or is contained within Niflheimr.

The father of the gods, one of three brothers (along with Vili and Vé) who murdered Ymir and built the world from his corpse. Odin is a complex figure: god of war, wisdom, poetry, magic, and death.

His name also means “the terrible one,” and Yggdrasil (“Odin’s horse”) is named after the gallows on which Odin hung himself for nine nights, pierced by his own spear, to gain the knowledge of the runes.

“Drill-tooth.” A squirrel who runs endlessly up and down the trunk of Yggdrasil, carrying messages—specifically insults and provocations—between the eagle at the crown and the dragon Níðhöggr at the roots.

Ratatoskr doesn’t attack the tree directly. Instead, he makes sure the conflict between the forces at the top and bottom never resolves. He is the being who escalates tension through gossip, who keeps the cosmos from finding peace.

In Norse mythology, Ratatoskr is often portrayed humorously—a busybody squirrel among cosmic forces. But the humor has a point: in a universe where everything either sustains or destroys, Ratatoskr is the one who ensures destruction continues.

The World Tree—“Odin’s horse.” Named after a gallows, Yggdrasil holds all nine worlds in its branches and roots. It is the spine of the Norse cosmos.

Unlike eternal, indestructible pillars in other mythologies, Yggdrasil is alive and dying. Its bark rots on the sides. A dragon gnaws at it from below. Four deer strip its leaves. A squirrel carries insults up and down its trunk. The only thing keeping it alive is the daily work of the three Norns, who pour water and pack healing clay into its wounds.

The first living being in the Norse cosmos, formed from primordial venom-ice at the meeting of Niflheimr and Múspellsheimr. Ymir was neither a god nor a hero—a primordial giant, enormous and incomprehensible in scale.

Ymir did not create the world. The three brothers Odin, Vili, and Vé murdered him and constructed the cosmos from his body: his flesh became earth, his blood became oceans, his bones became mountains, his teeth became rocks, and his skull became the sky.
