Thanks for that very detailed review, Sneeky. I've read the first two, in fact they were the first two AD&D novels I ever read. I enjoyed Artifact of Evil more of the two, though Gygaz has a bit of a quaint style of prose. He sounds more like someone documenting a series of PnP adventures, which isn't necessarily a bad thing. It's definitely a great repository of information on some of the more classic infernal and abyssal powers which span worlds in AD&D.
One thing though: if Mephistopheles is the Overlord of Baator, then whatever happened to Asmodeus?
