Aulë is an Ainu, and the most powerful of the Valar after Manwë, Varda, and Ulmo. His spouse is Yavanna. He is the master of crafts and the knowledge of substance, having fashioned the very elements of which Arda was composed. Yet for his love of skill and craft he is concerned with neither mastery nor possession, and is both humble and compassionate. Among the greatest of his works were the Two Lamps of the Valar, the vessels of the Sun and Moon, and the Dwarves.
He is also known as the Smith, the Maker, and the Friend of the Noldor. The Dwarves know him as Mahal.
