This afternoon today, Paul Stormberg of The Collector's Trove held a Q&A session over on reddit about the contents of Gary Gygax's unpublished manuscripts:
Adventurers wanted for hazardous journey, 
small wages, bitter cold, long months of complete darkness, constant 
danger, safe return doubtful, honor and recognition in case of success! 
This
 is an AMA, wherein I allow adventurers to ask me anything about the 
trove of treasures left behind by Gary Gygax, co-creator of Dungeons 
& Dragons, and what traps and guardians await them.
Gail Gygax's agent, Gina Ramirez, also participated in the AMA, covering questions around licensing as well as future publishing plans for computer games, RPGs, etc.
In the Q&A discussion, Paul offered several interesting revelations about the contents of the Gygax collection, including details relevant to the original Greyhawk campaign!
I'm quoting Paul throughout the text below, and also quote a few of the asked questions for context, as well.  And here's a quick mini-TOC in case you want to jump among the topics later:
- 
- 
JustOneAmongMany's Q:  "Presuming
 that you've looked at (or, hopefully, catalogued) the entirety of the 
material, can you break it down into percentages by category? e.g. 10% 
Greyhawk, 25% Lejendary Adventures, 15% novels, etc.?" 
 
 Paul's A:  "I'd
 say it breaks down to 30% product (comp copies and author's copies of 
product), 15% correspondence, 15% personal materials (play copies of 
games, dice, desk knick knacks, awards, etc.) , 40% game design 
materials (manuscripts, maps, notes, etc.).- 
- 
 "Of
 the design materials: novels and short stories 20%, original campaign 
materials 30%, new unpublished designs 50% (fiction, board games, card 
games, computer games, adventures, RPGs)."
 
 
- 
Paul:  "The manuscript for Gary's, unpublished, 
original home campaign is still extant! Indeed, I have unearthed the 
original castle manuscript of 22 levels. Also, the larger, expanded 
castle of 62 levels is also intact and well secured by Gary's widow, 
Gail Gygax. - 
"Additionally, there are over
 a dozen alternate levels that were used to change out levels depending 
on who was playing. In total nearly 100 levels of the castle exist with 
some 300 pages of keys."   
- Paul:  "Finding and reading the entry of the imprisoned demigods in Gary's original castle was pretty cool too!
 
 "The
 demigods are different than what was published and what transpired in 
the game and later related historically is also different -- totally 
stunned when I read it and as thrilled as Carter when I discovered it.
 
 "Remember,
 Gary was actively running his home campaign. He was very careful about 
revealing secrets and rarely published his personal campaign material. 
If he spoke of it he was careful not to reveal too much."
- Zenopus Archives Q: "What  are publication plans for the 
original Castle material that we know of,  specifically the binder 
maps/keys, the demo of level 1 at Origins  (which you have run at Gary 
Con), and the Teeth of Barkash Nour  tournament level?"
 
 Paul's A:
"Of course I am well aware of both of those properties and they have 
been incorporated back into the original castle. We have looked at 
different options and have met with several interested parties. This is 
Gary's magnum opus of game design and we want to be partnered with the 
right sort of publisher and developer.
 
 "Gary
 was very clear to his wife Gail on how he wanted this to be presented. 
She is striving to follow his wishes and find the best possible partner 
in this. Many are eager to be involved and have incredible heart but the
 effort must be exceptionally professional and of the utmost quality."
- Paul:  "Indeed
 the original manuscript exists but more interestingly, Gary's original 
campaign notes, maps, and keys exist! Gary had an incredible epic 
planned for this legendary adventure but he was never able to realize it
 and turned over only the partial, typed manuscript to Frank Mentzer to 
finish.
 
 "Thus the real adventure lies in 
the the treasures of the Gygax vault. Indeed, the maps for the home 
campaign dungeon are totally different than the published version and 
his original notes from 1977 lay out a far different campaign than was 
published.
 
 "I have personally discussed 
these with Mike Mearls of Hasbro and Erik Mona of Paizo and, despite 
their immersed nature in the game and years of experience, were duly 
astonished and thrilled by the thought of the campaign laid out by Gary."
 
 
 
Paul very generously answered at length the questions I submitted, so I'm reproducing them here in full:
- grodog Q #1: Given your access to and visibility 
across Gary's full career of creative work output, what do you consider 
Gary's best game designs, and why?
 
 Paul's A: "I 
really think the G-series and D-series, especially G1 for the economy of
 words -- I think like 6 pages of actual adventure -- Gary demonstrated 
what you really need to run a great sword and sorcery adventure. No 
prose is wasted on the DM and there is no padding that gets in the way 
of running the adventure. Nonetheless, it is one of the all-time beloved
 adventures and has to be one of the most published adventures of all 
time.
 
 "Like artists, I think all 
designers suffer in their sophomore efforts D&D and the AD&D are
 right on in tone and usefulness. The DMG is a giant in RPG design and 
is the bible for DM's of any stripe. It is an endless well of great 
advice and inspirational and instructive writing without having one mote
 of dull writing. Gary's sophomore effort was Unearthed Arcana, 
admittedly forced by circumstances. It broke all of his rules set forth 
in the first three books. While it is beloved by some it is polarizing."
- grodog Q #2:
 "Similarly, what undiscovered gems in Gary's work that are either very 
rare or unpublished have you seen that you would most want to see 
published, and why?"
 
 Paul's A:  "His smallest samurai books are among my favorites for non-RPG materials.
 
 "So
 many levels of his original castle that have never been mentioned 
publicly -- wow! The Teeth of Barkash Nour lying undiscovered for years 
is a fantastic one. He has another adventure where the players must 
enter the Egyptian underworld, recover pieces of their souls, travel 
through the various underworlds, face their present aspect of their 
ruler, and ultimately ascend out of the place if they succeed. Great 
adventure!
 
 "Of course, the whole castle 
reigns supreme as far as crown jewels go but wow do I love Gary's 
original Temple of Elemental Evil home campaign! It really blows my mind
 the the incredible campaign arc he outlined back in 1977 was never 
realized! It really give me goosebumps when I describe it."
- grodog Q #3:
 "Gail Gygax has talked in the past about wanting to publish Gary's IP in
 a variety of formats: movies, video games, RPG products, etc. Does she 
have any updates in the works for Gary's IP that you can share?"
 
 Paul's A:  "The
 update is that we are still wanting to find the right partner on a 
variety of projects. There have been some heartfelt efforts and some 
incredibly professional ones. We hope to start closing in on product 
lines in the near future.
 
 "Gina Ramirez, Gail's agent, will have some more to add as she has been shoulder to should with Gail on this."
- grodog Q #4:
" Among the World of Greyhawk materials in the collection, do these 
known-but-unpublished manuscripts still survive, and if so, to what 
extent?---that is, can please you describe what survives in terms of 
maps, content outlines, written pages, art orders, etc.: 
- Wasps Nest: 
the City of Stoink, 
- the missing Geomorphs sets: Dungeon Geos "Rooms, 
Chambers & Passages - Set Four and Outdoor Geos Set Two 
(Castle/Fortress) and Set Three (Ruins), 
- new class materials for 
Gary's proto-second-edition for the Bard, Hunter, Jester, Mountebank, 
Mystic, and Savant, 
- the City of Greyhawk in it's various forms 
(small, medium, and large?), and 
- last but certainly not least, Castle
 Greyhawk in its two (or more?) formats as the Original Castle and the 
Expanded Castle." 
Paul's A: 
- None but all of Dyvers exists.  
- None. 
- Hunter, Mountebank, Mystic, and Savant only.
- All. 
- The manuscript for Gary's, unpublished, original home campaign is still
 extant! Indeed, I have unearthed the original castle manuscript of 22 
levels. Also, the larger, expanded castle of 62 levels is intact and 
well secured by Gary's widow, Gail Gygax. Additionally, there are over a
 dozen alternate levels that were used to change out levels depending on
 who was playing. In total nearly 100 levels of the castle exist with 
some 300 pages of keys.
- grodog Q #5:
 What do you consider Gary's most important role at TSR?: his work as an
 game designer/creator of original content vs. his work organizing, 
editing, and bringing together the diverse contributions from Arneson, 
Kuntz, Marsh, Lakofka, Lucien, and many others vs. his work as a 
visionary and leader scaling up the hobby as a whole (with TSR atop, of 
course), or some other role I've not described?
 
 Paul's A:
 Certainly we would not have D&D or AD&D and many of the beloved
 works associated with Gary's company TSR without his endless energy to 
network, connect, inspire, encourage, collate, collaborate, and publish 
the disparate contributions of so many. Ultimately these contributions 
end up under Gary's hand but there is no denying Gary's own ability to 
create and his vision are the reason we all have a beloved pastime.
 
 Gary's
 greatest impact on the company was probably the patriarchal role he 
played from the IFW days to TSR's heyday. He really had a cult of 
personality among the creative types and even other employees. This 
would bring the Blume's much grief as they tried to run the company 
under their edicts.
Also very noteworthy is that the Gygax Games web site has a new facelift, and it sounds like Paul and Gina will be helping to maintain it going-forward (if I'm interpreting their comments properly).  
Under the Gary's Archive page is a picture of the Museum of the Gods map from the Castle Zagyg manuscript, too!:

| Gary Gygax's Museum of the Gods map from the Castle Zagyg manuscript, unseen for 45 years!

You can also download the 
full-size version, too. 
Paul's video on the same page introduces the collection, and mentions the new Gygax Games Twitter account will be providing future updates, as well:  @gygaxgames.
All-in-all, this was a fine day for a Greyhawk fan, and I'm very curious to hear what more news may be revealed at GaryCon 11 in a couple of short months!
Allan.
