Muspelheim- Norse LocationLocation · Realm"World of Fire"

Before the World

Múspelheim exists before the gods, before the giants, before the worlds. It occupies the southern extreme of the cosmos, and Snorri describes it in the Gylfaginning as "bright and hot, blazing and burning, impassable to all those who are foreigners and have no heritage there." At its border stands Surtr, flaming sword in hand, guarding the frontier between fire and everything else. He has stood there since before time began.

Before anything was made, there was only Ginnungagap, the yawning void, flanked by Niflheim in the north and Múspelheim in the south. Niflheim sent its frozen rivers, the Élivágar, flowing into the void. Múspelheim radiated heat and scattered sparks and embers into the emptiness. Where these forces met in the middle of Ginnungagap, the air became as mild as a windless day. The ice began to thaw. From the drops that formed as warmth met frost, the first living being stirred: Ymir, the primordial giant from whose dismembered body the gods would fashion the earth, the sea, and the sky.

The Stars

After Odin, Vili, and Vé had shaped the world from Ymir's flesh, they turned to the problem of darkness. They took wandering sparks and glowing embers from Múspelheim and set them in the firmament. These became the stars, and the brightest were given courses to mark the passage of days and seasons. Vafþrúðnismál preserves the giant Vafþrúðnir's account of how the celestial bodies were established, confirming that the fire realm's scattered light was the raw material of the heavens.

Surtr

Surtr's flaming sword burns brighter than the sun. The Völuspá names him as the one who comes "from the south with the destroyer of branches," a kenning for fire. His patience spans the full duration of the cosmos. He waits at Múspelheim's border for the appointed time, neither attacking early nor leaving his post.

The "sons of Múspel," the Múspellsynir, form the army that will march at Ragnarök. These fire beings are native to the burning realm, shaped by its flames. Both the Völuspá and the Prose Edda name them as a distinct host, separate from the frost giants.

Ragnarök

When the end comes, Surtr will lead the sons of Múspel northward. They will ride across Bifröst, the rainbow bridge, and it will shatter and collapse behind them under their weight and heat. On the plain of Vígríðr they will join forces with the frost giants, Fenrir, Jörmungandr, and the armies Loki has rallied.

Surtr will face Freyr. The Vanir god had given away his magic sword to his servant Skírnir as the price of winning the giantess Gerðr's love. Without that blade, Freyr will fall. After the slaughter, Surtr will cast fire over the whole earth. The flames will consume everything. Fire will leap high enough to lick heaven. The sun will go dark, the stars will vanish, and smoke and steam will rise from the sea.

Then the earth will rise again from the waters, green and renewed.
