Any reason why Gruumsh couldn't be considered a Demon Lord? He *is* CE now.
Because demon lords are intrinsically linked to the Abyss, and Gruumsh isn't in the Abyss?

Dude. Homebrew. Gruumsh can be as associated with the Abyss (or rule the whole thing, using Demogorgon for a carpet and Dagon for sushi) if the DM wants it.
I often use Vampric the Destroyer when making "non traditional" orcs. Vamprac (Vampric, something like that) is the evil god of Ogres and Trolls (I think) and at some point, in some book, some where was associated with the Demon Lords. I think.
