I have had this discussion many times with fellow Ringers (LOTR fans) and i have come to the conclusion that he
might be Iluvator. Just somthing for you to chew on.... after all; he said that he was there before the first acorn, the first raindrop and before the elves. Of course lots of people disagreed... but i dont see any other option.

BTW, i'm new... so forgive me for any stupid thing i've said in the past.
