The Valar's Appearance

[Lord of Angmar]

I totally disagree with Novberaid. The may have been Gods, but they can only have one form. At least that is my opion.

Well, your opinion is wrong. The Valar did not have one true form, unless you call their spirit a 'form', which would be inaccurate. If you are talking about physical forms, then you are mistaken, for they can take on any carnate form they wish. The only exception to this was Melkor, and this was only because he poured so much of his strength into Arda that he was in a 'fallen' state, and was not counted amongst the Ainur anymore.

The Valar's one true form is not physical at all but spiritual, and it can be manifest in any different physical form that they see fit to wear.
