Celegorm was the third son of Fëanor. He was the most woodcrafty of the High-elves, and sometimes called the Huntsman of the Noldor. He was also the master of the Hound of Valinor, Huan. Like the rest of his brothers, with whom he swore the Oath of Fëanor, he was overly proud and tended to act more by force than by deceit.
Upon his return to Middle-earth, he played a major role in the victory of the Dagor-nuin-Giliath, and with his brother Curufin took up his abode in Himlad, where they remained until their realm was overthrown in the Dagor Bragollach.
The two fled to Nargothrond, where they opposed Finrod, who desired to aid Beren in the Quest of the Silmaril, and vowed anew the Oath of Fëanor. Not long after, Celegorm met and fell in love with Lúthien and forced her to come with him to Nargothrond so he could marry her. Huan forsook his master to aid Beren and Lúthien, foiling the brothers’ evil attempts to abduct Lúthien on two occasions; and though he returned briefly to his master’s side, he ultimately rejoined Beren and later died at his side.
