Vili, in Norse mythology, the brother of Odin and Ve, and one of the creators of the world and mankind. Odin, Vili, and Ve, the three sons of Bor and the giantess Bestla, were the first Aesir gods. They were strong, fair, and good, and they waged a war against the terrible Ymir and his offspring, the frost giants.
Together Odin, Vili, and Ve killed Ymir. They took his enormous body and put it in the middle of Ginnungagap, the chasm that spread from the frozen ice of Niflheim to the fiery realm of Muspelheim. From Ymir's body they created the landscape of the world: they made the land from his flesh; the mountains from his bones; the boulders and rocks from his teeth and broken knuckles; the lakes, rivers, and seas from his blood; and the trees and grass from his hair. They placed his skull high above the Earth to form the firmament. Ymir's brains became the clouds floating inside this skull-made sky. Each of the four corners of the sky was held up by a dwarf; their names were East, West, South, and North.
One day, after completing this task, the three Aesir were walking along the seashore when they found two pieces of driftwood--one of oak, the other of ash. From these, the gods whittled two beings, the first man and the first woman. Odin gave them breath and life, Vili gave them understanding and the power to feel, and Ve gave them warmth and human senses of speech, hearing, and sight. The three gods gave them clothing to wear. The man was called Ask (Ash) and the woman Embla (Oak), and all mortal beings descended from them. The gods designated Midgard as the place they could live.
A slightly different story of the creation of mankind appears in the 'Poetic (or Elder) Edda'. In this version, Bor's three sons are called Odin, Hoenir, and Lothur.
