Aulë
His lordship is over all the substances of which Arda is made. In the beginning he wrought much in fellowship with Manwë and Ulmo; and the fashioning of all lands was his labour. He is a smith and a master of all crafts, and he delights in works of skill, however small, as much as in the mighty building of old. His are the gems that lie deep in the Earth and the gold that is fair in the hand, no less than the walls of the mountains and the basins of the sea.
