Not especially.This one is older than 4E. I know that they rebranded demons and devils to fit this paradigm, I just don't see the need for it.
Hence my asking. If Grazzt was originally a devil, did he "morph" into an elemental? If he did, how could he possibly be a double agent in the Abyss (as the article suggests as possible)? As a matter of fact, *can* a creature's origin change?
Not especially.
Looking back to 1e there was nothing especially subtle or cunning about most Demon Lords. Jubilex, Orcus, Demogorgon. They fought amongst each other but it certainly didnt seem to involve the level of machination and politicking which the Arch devils seemed to possess.
If you go back to BECMi then its even more apparent. There you had demons which were the Immortals of Entropy, specifically interested in destroying all of existence.
I won't be using this shallow Demon / Devil mitology on my Planescape games, which will stay 3.5.
My 4.0 campaign it's an almost brainwashed Forgotten Realms game, so I could fit any new cosmology in.
Yep.Personally I hated the 3e cosmonology with a passion, a different plane for absolutley everything, way over detailed when it came to monsters and villians, I actually like the fluff light nature of it as it allows dms to be a lot more creative.
With Third Edition I had a lot of information I choose to use or not.
With Fourth I have almost no information and everything seems so generic and boring.
Maybe this is one of the ambiguities of the new cosmology that allows DMs to decide for themselves. Can a creature change its origin? Or can the Elemental Chaos and the Abyss change someone if they are there for too long?
