Varda was the most beautiful of all the Valar, and her beauty was said to be beyond the description of Men and Elves, for her face radiates the light of Eru Ilúvatar. Unsurprisingly, the province over which she ruled was light, to the extent where it was said that "in light is her power and her joy"
Because of her creation of the stars, the Elves of Middle-earth revere and love her the most out of the Valar. They even gave her the name of "Elbereth", invoke her in times where they require aid, and sing her praises whenever the stars rise. It was also said that when Manwë sits beside her upon their throne on Taniquetil, she was able to hear more clearly than any other ears, the prayers and laments of those in need from the furthest east even unto the west. At times, she would answer the prayers of not only Elves, but also those of other races. For example, during the War of the Ring, she aided Sam through the Phial of Galadriel (which contained the Light of Eärendil) during his struggle against Shelob.
