John Ronald Reuel Tolkien CBE, FRSL (3 January 1892 – 2 September 1973), known professionally as J. R. R. Tolkien, was an English writer, poet, philologist, and university professor who is best known as the author of the classic high-fantasy works The Hobbit, The Lord of the Rings, and The Silmarillion.
The Ainur were the primordial spirits, who existed with Ilúvatar, and with him created the world through The Ainulindalë, The Music of the Ainur. After the creation of Arda, many of the Ainur descended into it to guide and order its growth; of these there were fifteen more powerful than the rest. Fourteen of these great Ainur became the Valar, or Powers of Arda. The fifteenth, Melkor, turned aside from that path and became the first Lord of the Dark Powers.,,
