Those are awesome! Love Zargon especially. Wasn't that the D&D module with the weird mushroom farmers living in the pyramid? It's been so long since I've played some of these old modules, I tend to get them all mixed up.
It was B4 The Lost City, which does indeed have a subterranean race of albino humans who live in a pyramid and worship the hideous Zargon.
