Nahar was the white horse of the Vala Oromë. In the day he gleamed in white, and he shone like silver in the shadows at night and his hooves were golden.

It is said that Nahar was shod with gold as he led the hosts of the Eldalië from Cuiviénen with Oromë on his back.

Nahar bore Oromë during the pursuit of Melkor and Ungoliant after the death of the Two Trees. The earth trembled and shook beneath the golden hooves of Nahar and the fire that struck out from them was the first light that returned to Valinor.
