Each of the Maiar was associated with one or more particular Vala. For example, Ossė, as a spirit of the sea, belonged to Ulmo, while Curumo, who came to be known in Middle-earth as Saruman, belonged to Aulė the Smith. Others included Sauron (originally also of Aulė's people), and Olórin, known as Gandalf, who belonged to Manwė and Varda.
