Phobos and Deimos are the twin sons of Ares. They ride their fathers chariot into war spreading panic and fear among mortals in the battlefield. Because their mother is Aphrodite, goddess of love, the twins also represent the fear of loss. "Dark Trojan by GAVade.deviantart.com"
Because of her creation of the stars, Varda was the dearest of the Valar to the elves, who called to her for aid from Middle-earth. The Valar are divine beings below a greater, more ultimate Creator, Ilúvatar. Thus some equate the Valar of Middle-earth with saints and angels; thus Varda, in her role as the most loved and prayed-to Vala, may be an equivalent of the Virgin Mary in Tolkien's own Catholic faith.
