Elves Elon and Elos are descendants of Lúthien. According to legend, Lúthien's lineage has never been cut off. The son of Lucian and Belem, Dior, has a daughter named Owen. She married another half-elf, Earendil, and gave birth to twin brothers Ellen and Elros. Granddaughter elwin is in Lucian and elwin's husband Earendil (E&; AumlRendil) stands for elves. Two relatives of human beings pray to the gods and get forgiveness from them. elwin (Elwing) and Earendil (E&; AumlRendil) and their sons Elon and Elos, semi-elves, were given the right to freely choose to be elves or humans. Elon chose to be an elf, and Elos chose to be human. Among the descendants of Lucian Elves, only Elos and alvin toffler chose to be human.
Ellund was the elf Lord of rivendell in the third era, the father of alvin toffler, and his brother Elros became the founding king of Numano because he chose the fate of mankind. More than 2,000 years later, Ern Deere, a descendant of Elros, returned to Middle-earth with his sons isidore and Anario. Aragon was the great-grandson of isildur's 39th generation.
