Gary, I have a set of related GH queries for you, and this one takes a bit of a preamble to get going.
I've heard variously among the GH diehards that Zagyg and Xagy were actually different beings, and that Xagy was Zagyg's evil twin. I don't recall offhand where I read this, it was likely either in one of your Q&A sessions with Paul Stormberg, in an earlier thread here on ENWorld, or in passing conversation with Scotty, Gene, or somesuch GH grognard.
Joramy and Xagy helped to create Queen Ehlissa's Marvelous Nightingale, according to Mordy (he could be wrong, of course....). I've also read (somewhere) that Joramy was evil in your original GH campaign, which would explain her willingness to work with Xagy to create the artifact. In Eldritch Wizardry, Dave Sutherland's image of Orcus being summoned in the presence of the Nightingale (though no obvious influence via the Nightingale is shown) is particularly interesting, in light of Xagy and Joramy's possible evil alignments.
Given all of that, my questions to you are several fold: Was the illo in EW a picture of Ehlissa summoning Orcus, and if so, was she evil (for some reason, I'd always assumed that she was good, perhaps because she reigned for several centuries, which---in combination with her name---made me think she was olven). Is Xagy a different person from Zagyg? What is Xagy's relationship to Zagyg? Is Xagy also a deity, or is he long dead by 576 CY? If he's alive, does Xagy oppose Zagyg? Lastly, will Xagy appear in any of the Castle Zagyg publications?
If that looks as nonsensical as I think it does, I'm sure that Zagig would be well-pleased
