Maiar in physical form

[lore_master]

also, Sauron's real or "spiritial" form was not the great eye, the Aniur's(Valar and Miar) real forms were not visible, except for maybe a white/light light blue or red almost translucent flame.

I agree that Sauron's blodd mingled with the ring and he needed it to regain the strength he once had.
