Gary,
So nice to be able to chat with an industry legend... heck, pretty much
the industry legend, for industry = RPG.
I've been lurking here for awhile, and reading your stuff got me interested in... reading your stuff

so I dug out my old worn copies of the Gord books and am about halfway through right now. Still love them for what they reveal about your ideas for Oerth-- how I wish we had seen what you had in mind for Western Oerik and the other continents, too, aside from the bare hints we get from some of the characters Gord meets in
Sea of Death.
A couple of quick questions: you mention tons of new Lower Planes denizens in the later Gord books, but the ones that jump out at me are the dumalduns, the dreggals, and the maelvis. If I recall correctly, you revealed (in the fight in Gravestone's lair) that the dumalduns were composed of malign and fell homonids (chimps, mandrills, gorillas, etc.) so I can sort of imagine the various species of dumalduns fairly well, and how to develop them in my own Greyhawk campaigns.
But what of dreggals, maelvis? Cacodemons (from Pandemonium, perhaps)? Did you actually have these defined in your campaign, or in your head, or did you just name them and figure you'd detail them when/if Gord ever encountered them? I don't hope for AD&D stats for them, but just a thumbnail sketch, perhaps? "Maelvis are automatons shaped like various living beings" and "Dreggals look like balloon animals" would be sufficient to get my imagination spinning in the right direction.
Also, in a completely separate question, how much of Gord's story changed post-TSR? At the time, I thought you had modified Gord's tale to make him more powerful and take it him a direction which would divorce him more and more from the portions of his world owned by TSR. But rereading your intro to "At Moonset, Blackcat Comes", you identified his destiny as "deposer of deities" even then, so I'm back to believing you had most of his life and times planned out (except perhaps the ultimate end of
Dance of Demons-- I've got to think you wouldn't have decimated Oerth if Certain Witches had not caused you to lose the reins behind it.)
In a humorous anecdote, some time after
Dance of Demons was published, someone wrote into Dragon magazine inquiring what the future of the Greyhawk product line would be now that Oerth was destroyed. The answering editor either didn't know about
Dance of Demons or he deliberately pretended not to, as his answer was something like, "What are you talking about? Oerth is not destroyed. In fact, next month, TSR will release it's latest in a line of great Greyhawk modules entitled..."
Count me in for more Gord novels, BTW: and I second the suggestion made by a poster somewhere upstream: detail the ten years of Gord's llife on the high seas that we miss between
Sea of Death and
Come Endless Darkness. Buccaneering, Hepmonaland and the Amedio Jungle (sorry, those are probably copyright someone else now... "The Land of the Hep-men and the Amdemio Rain Forest")... I'd love to see Gord's adventures on the high seas with Barrel and Dohojar, zehaab.
