Bor's sons had a raging hatred towards the giant Ymir, and they plotted his death. Ymir's corpse was carried to the center of Ginnungagap and cut into many pieces. Odin, Vili, and Ve fashioned the world out of Ymir's body.

From Ymir's flesh they made the earth, and the mountains from his unbroken bones. From Ymir's shattered skeleton parts, teeth, and toes they created pebbles, boulders and rocks. Ymir's flowing blood gave rise to the rivers, lakes, and sea. Maggots grew from Ymir's rotting carcass,and they were shaped into dwarfs.

Odin, Vili, and Ve lifted Ymir's skull so high it reached the end of the earth's limits, and they called it the sky. The sons of Bor placed a dwarf on each of the four corners to hold it over the earth. Their names were: Nordri, Sudri, Austri, and Vestri.

Odin, Vili, and Ve snatched glowing embers from the realm of Muspellheim and fashioned the sun, moon, and stars. These orbs were placed above the world to illuminate the earth. Some stars were given a fixed point in the sky, while others were allowed to dance freely.
