The sons of Fingolfin were Fingon, who was afterwards King of the Noldor in the north of the world, and Turgon, lord of Gondolin; their sister was Aredhel the White. She was younger in the years of the Eldar than her brothers; and when she was grown to full stature and beauty she was tall and strong, and loved much to ride and hunt in the forests. There she was often in the company of the sons of Fëanor, her kin; but to none was her heart's love given. Ar-Feiniel she was called, the White Lady of the Noldor, for she was pale though her hair was dark, and she was never arrayed but in silver and white.
