CelebrimborCelebrimbor - Celebrimbor was the son of Curufin, the fifth son of Fëanor.  He was also a master craftsman.  In fact his name means "Hand of Silver".

 

"In Eregion the master craftsmen of the Gwaith-i-Mirdain, the people of the Jewel-smiths, surpassed in cunning all that have ever wrought save only Fëanor himself; and indeed greatest in skill among them was Celebrimbor, son of Curufin..." ~The Silmarillion (Of the Rings of Power and the Third Age)

 

And when Celeborn and Galadriel left Eregion (see Lothlórien), Celebrimbor became the undisputed leader of the Elvish outpost.  He immediately strengthened ties with the Dwarves of Moria, whom Celeborn had despised.

 

"Galadriel and Celeborn had in their company a Noldorin craftsmen named Celebrimbor.  Celebrimbor had an almost 'dwarvish' obsesseion with crafts; and he soon became the chief artificer of Eregion, entering into a close relationship with the Dwarves of Khazaddȗm, among whom his greatest friend was Narvi.  Both Elves and Dwarves had great profit from this association; so that Eregion became far stronger, and Khazad-dȗm far more beautiful, than either would have done alone...Celebrimbor is called the Lord of Eregion." ~Unfinished Tales (The History of Galadriel and Celeborn)
