Okay, I'll admit that I was going out a bit on a limb with Ungoliant...

Perhaps it would be wrong to call her a Maia, as such...

She is definitely an Ainu, though. There is no debating that all the spirits created by Eru in the beginning, in time for the Music, were the Ainur, and that all the spirits who came to Arda in the beginning of the world were, of necessity, Ainur.

Here's where I perhaps made my mistake, that of automatically classifying each and every Ainu who came to Arda as either a Vala or a Maia. This strategy would seem to be born out by the Valaquenta, but I'll admit that it might be more accurate to say that all the Ainur in Arda were ORIGINALLY classified as either Valar or Maiar, and that those who turned evil lost the designation. In any event, I am willing to admit that I could have been wrong in my application of the term.

Perhaps she wasn't a Maia, persay, but she MUST have been an Ainu. She must have been one of the those spirits who created the Music for Eru, or at least the offspring of such. What else can she have been?

And while the term Ainur is not really used in the context of the spirits attendant at the Music once they are in Arda, where the terms Valar, Maiar, Balrogs, Istari, etc. are more proper and correct, the fact remains that all of these must have in origin been Ainur.
