Get some sunshine!
Too much Sauron on my dash - you made me do this, guys!
So, here goes a cutie pouty Sauron with long black hair, long lashes, and no idea about what he’s doing. Pointy ears, because I think that Valar and Maiar would look more similar to the Eldar then to Men. Also, he must have been really fond of rings, ever since the first ones of them were made. I reckon that you don’t bind the essence of your soul to a piece of jewelry unless you have ever been heavilly obsessed about those.
And of course, since I’ve read the Black Book or Arda I assume Sauron is Melkor’s Maia, not Aüle’s :) Hence the darkness being his element as well.
