Muspelheim

Muspelheim: Contrasted with Niflheim.

Two realms were spoken of: Niflheim and Muspelheim.

Niflheim is the misty region of the north, the dawning mist-filled conditions of the Hyperborean root race, in contrast to Muspelheim.

The World Ice Theory

The universe begins with two primordial realms—Niflheim (home of mist) and Muspelheim (home of fire).

From the mist of Niflheim and the heat of Muspelheim, the first being, Ymir, a frost giant, is formed.

According to the myth, Ymir was the first being in the universe, a primordial giant born from the melting ice of Niflheim when it met the hot air of Muspelheim, two of the nine worlds in Norse cosmology.

To the south is Muspelheim, a world ablaze with fire and heat.

When the ice of Niflheim met the fires of Muspelheim in the middle of Ginnungagap, the ice began to melt, forming the figure of Ymir, the first of the frost giants.

Meanwhile, as more ice melted by the heat of Muspelheim, another figure was formed—Búri, the first of the gods.

Ginnungagap is situated between Niflheim, the realm of ice and cold, and Muspelheim, the realm of fire and heat.

This positioning is crucial because the interactions between the ice of Niflheim and the fires of Muspelheim across Ginnungagap are what led to the creation of Ymir, the first being, and subsequently, the rest of the cosmos.

Surrounding Ginnungagap are the realms of Niflheim (a world of ice) and Muspelheim (a world of fire), whose interactions eventually lead to the creation of the world, including the Earth, from the body of the giant Ymir.
