Now as has been told the power of Elwë and Melian increased in Middle-earth, and all the Elves of Beleriand, from the mariners of Círdan to the wandering hunters of the Blue Mountains beyond the River Gelion, owned Elwë as their lord; Elu Thingol he was called, King Greymantle, in the tongue of his people. They are called the Sindar, the Grey-elves of starlit Beleriand; and although they were Moriquendi, under the lordship of Thingol and the teaching of Melian they became the fairest and the most wise and skilful of all the Elves of Middle-earth.
