Arien

Called the Sun-maiden, Arien was a spirit of fire who originally belonged to the Maiar of Vána. During the Years of the Trees, it was her role to bring the glowing dews of the Golden Tree Laurelin to Vána's gardens. At that time she took a form similar to one of the Children of Ilúvatar, but even so her fiery spirit could be seen in the brilliant glow of her eyes.

When the Valar created the Sun from Laurelin's last fruit, Arien was given the task of directing it through the sky. At that time she cast off her old shape, and took on the appearance of a brilliantly burning flame. In that form she took charge of the vessel that Aulë had made for the new Sun, and guided it along its course above the World.
