§ Of Maeglin The Silmarillion

As Maeglin grew to full stature he resembled in face and form rather his kindred of the Noldor, but in mood and mind he was the son of his father. His words were few save in matters that touched him near, and then his voice had a power to move those that heard him and to overthrow those that withstood him. He was tall and black-haired; his eyes were dark, yet bright and keen as the eyes of the Noldor, and his skin was white. Often he went with Eöl to the cities of the Dwarves in the east of Ered Lindon, and there he learned eagerly what they would teach, and above all the craft of finding the ores of metals in the mountains.
