Celebrimbor was a Ñoldorin prince and the last in the line of the House of Fëanor, who lived in Middle-earth. He was a ruler of Eregion in the Second Age, and a master smith. He is remembered primarily for his creation of the Three Rings of Power: Nenya, Vilya, and Narya, but also he made the second Elfstone (in one version) for Galadriel, who later gave it to Aragorn.
