Middle-earth History Meme: 2/3 Elves: Elwing
Elwing was the daughter of Dior and wife of Earendil. Her sons were Elros and Elrond. After the sack of Doriath she fled with the Silmaril of Beren and Luthien to the Havens of Sirion. In F.A. 538 the remaining sons of Fëanor attacked the Havens to take the Silmaril. They captured Elwing’s sons but as they came for her she cast herself into the Great Sea. Through the power of the Vala Ulmo, she took the form of a white bird and came to her husband in his ship Vingilótë with the Silmaril upon her breast.
Elwing sailed with her husband on his great voyage to Valinor. When the Valar allowed Eärendil and Elwing, both being Half-elven, to choose which of the races they would be members of, Elwing decided to be counted among the Elves, as did her husband for her sake. Elwing was given a tower to live in by the shores of Eldamar, and there she fed seabirds that came to her windows. Eventually she learned their language, and was able to transform into a swan. They still dwell in Aman and she flies out in her swan form to meet Eärendil when he returns from his voyages through the sky.
