middle earth meme: [1/3 races] the maiar (specifically, some of my favourites)
The Maiar were Ainur, offspring of Eru Ilúvatar’s thoughts before the world was made. They were akin to the Valar but lesser in power than the Holy Ones who were the chief shapers of the world. The Maiar were typically devoted to and served specific Valar, being of like stock. For example, Eönwë and Ilmarë, who together were Chiefs of the Maiar, served Manwë and Varda respectively, while Sauron was of Aulë’s folk before being seduced into the service of Melkor. The Maiar were fëar (spirits) but unlike the Children of Ilúvatar, they do not need to possess hröar (bodies) to appear to the Children, manifesting themselves in a fana (vales). It is insinuated, in the tale of Melian the Maia and Elu Thingol the Elf, that should a Maia wed with one of the Children they shall take up Elven forms and be bound forever to them. They are immortal, and like the Elves, they are bound to Arda until its end and cannot die in the matter of the Children, though their spirits may be weakened to the point of never again causing harm, such as the case of Sauron after the destruction of the One Ring. Among the Maiar were Balrogs, who were those corrupted by Melkor the Marrer.
