Lord of Eregion

Celebrimbor was the son of Curufin, who was in turn the son of Fëanor himself. He became the greatest of the Mírdain, the Jewel-smiths of Eregion, and was acknowledged as their leader and lord.

It is not certain whether Celebrimbor was the Lord of Eregion throughout its history. The references to him in The Lord of the Rings seem to suggest this, but other materials in Unfinished Tales hint that Eregion might in fact have been founded by Galadriel and Celeborn, with Celebrimbor only becoming its lord later in its history. This seems to be a point on which Tolkien changed his mind: the title ‘Lord of Eregion’only appeared with the revised edition of The Lord of the Rings.
