Boldogs, Gothmogs and Sauron's New Clothes

[the phantom]

Might they perhaps be candidate for Boldog-ship?

How about that orc captain in Moria that stabbed Frodo. He seemed to be a bit special. I don't recall that every orc let off a flash of light when their heads were hewn.

Whether this applies to Melkor alone, or also to lesser fallen Ainu, is not clear.

After all, Ungoliant had offspring.

Yep, yep. Just because an Ainu goes bad doesn't mean they can't reproduce.

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?

Melkor stuck spirits and such in dragons and wolves, so we know he could house spirits. So why not rehouse? Elves were rehoused after they died, so we know it's possible to rehouse a spirit.
