[1]  [DOC] The Valar (singular Vala) are characters in J. R. R. Tolkien's legendarium. They are "gods" or "angelic beings" subordinate to the one God (Eru Ilúvatar); they are the most powerful of the Ainur who chose to go into the World (Arda) and complete its material development after its form was determined by the Music of the Ainur (Ainulindalë). For this reason they are also referred to as "the Powers of the World." They are mentioned in "The Lord of the Rings", but were developed earlier in material published posthumously in "The Silmarillion" and "The History of Middle-earth". [END]
