Boldogs, Gothmogs and Sauron's New Clothes

[Neithan]

Also, Ungoliante was not an Umaia.

Isn't this debatable? I always thought that she was a powerful Ainu and that she was one of those who went over to Melkor during the Music. But after they came to Arda and began shaping it Ungoliant left Melkor to fulfill her own purposes. Isn't it also possible that she was one of the people of Varda or at least had something to do with light and that Melkor corrupted her so that she became somewhat the opposite.

I think that it was possible for a spirit that had died as an Incarnate to be reembodied by a more powerful being.

An interesting thought but what are you basing it on?

I don't think that the two Gothmogs are the same, the Lord of Balrogs was just a little to great to be associated with a mere Boldog.
