Melkor

Morgoth , also known as Melkor , was the greatest of the Ainur . He fell from glory when he disrupted the Music of the Ainur and defied the will of Ilúvatar . Morgoth corrupted many of the Ainur to his service, fought the Valar , and marred Arda . His theft of the Silmarils and wars against Elves and Men encompassed much of the history of the late First Age . Eventually, Morgoth was bound in chains by the Valar and thrown into the Void , leaving the permanent damage his evils had done, and his former lieutenant Sauron , to trouble the world.
