I'm planning on creating a poem for each of the major spirits in Tolkien's Valaquenta section of The Silmarillion, and so I'm starting with the Queen.
Varda (a.k.a. Elbereth, Gilthoniel, Eléntari) is the Queen of the Stars. She came out of the deeps to help her husband Manwë defeat Melkor, who feared her alone of all the Valar. Tolkien describes her as being too beautiful for mortals to look upon. From the light of the Two Trees she wrought the Lamps of Valinor, and is revered as the creatrix of the stars. She is mentioned in Galadriel's namarië hymn in The Fellowship of the Ring.
