Silmarillion - Ainulindale

[Raynor]

Rebel or Nameless Goody-goody - it seems the Author has already penned what will in the long run be happening.

Well... Eru is named the "one wholly free Will and Agent" (letter #156); ultimately, _all_ creation, from Ainu to rocks, is a manifestation of Eru, so I don't see how any part of it could be wholly independent of him. But that doesn't preclude manifestations of individual free wills on a less than complete degree.
