|World of Greyhawk Series (WG4 - 12)|
The first series of modules set in the World of Greyhawk campaign, for AD&D (along with the companion WGA and WGR series). Modules WG4 - WG7 are for 1st Edition rules; WG8 - WG12 are for 2nd Edition.
No modules were ever assigned codes WG1 - WG3. WG1 and WG2 were apparently earmarked for T1 Village of Hommlet and its planned sequel, Temple of Elemental Evil (thanks to Ian Malcomson for this info). WG3 was originally to be assigned to Lost Caverns of Tsojcanth, but that module ended up with code S4. WG4 Forgotten Temple of Tharizdun is the sequel (loosely tied) to that module.
WG4 Forgotten Temple of Tharizdun comes with a double cover (module booklet nested inside two covers of maps). The working title for it was "Forgotten Temple of Therizdum". Thanks to Eric Pass and Adam Shultz for this info.
WG5 Mordenkainen's Fantastic Adventure has a glaring spelling error on the cover of the module booklet: "Fantasy Word Adventure" in large letters. Additionally, there's an apparent error in the text, stating on the introductory page that the module is for "four characters, levels 8-14". However, the back-cover text, and the included pre-generated characters, indicate that the module is for character levels 9-12. Thanks to John Hall and Colin Steward for help with this info.
WG7 Castle Greyhawk is a compilation of humorous dungeon levels; the same castle was treated more seriously in WGR1 Greyhawk Ruins. Twelve levels are presented, each written by a different author(s): Steve Gilbert, Rick Swan, Guy LiMore, Greg Poehlein, David Tepool, Paul Jaquays, John Terra, Greg Gorden, Grant Boucher, Kurt Wenz, John Nephew, Scott Bennie, Rick Reid, Ray Winninger, and Steve Perrin.
The WG7 code was originally earmarked for a module entitled Shadowlords. From the Summer 1986 Mail Order Hobby Shop catalog: "A high-level module set in the World of Greyhawk. Journey to the perilous Plane of Shadow to rescue Princess Esterilla and confront the master of the plane... where you find yourself an unexpected guest at a wedding where the guests include a lizardman, a catlord, and a mistress of illusion!". Assigned TSR stock # 9184. Gary Gygax and Skip Williams were collaborating on the project, but it was shelved due to Gygax's lawsuit with TSR. Gygax has since stated that while Wizards of the Coast has given permission to have the module published, the fact that it will be produced "on spec" (no contract nor advance payment), makes it unlikely that he or Skip will be undertaking the project anytime soon. The original mention of it is in Dragon Magazine #37, page 10, where it's called "Shadowland".
From contributor Michael Falconer: "While WG8
Fate of Istus is copyright 1989 and bears the AD&D 2nd Edition logo and
'Compatible with the AD&D and the 2nd Edition AD&D Game Systems' starburst,
the module in fact seems to be written for 1st Edition. Monks and
Assassins are prominent, and page references are given to the 1st Edition
core rulebook manuals. Statistic blocks for NPCs are typical of late
1st Edition products -- for example, ability scores are given in order of
Str / Int / Wis / Dex / Con / Cha. Comeliness is absent, however, and
certain core 2nd Edition concepts like Ability Checks and THAC0 are given
special explanations in the Introduction. Clearly, WG8 was
written using the 1st Edition books as a reference but with some very
limited understanding of what was to come in 2nd Edition."
Further clarification provided by Alex Twiston-Davies: "It was designed to
bridge the gap between 1st and 2nd edition AD&D. The plot is based
around the idea that the Goddess Istus has decided to re-evaluate the
inhabitants of Oerth and make changes accordingly. Thus begins a
series of adventures, one for each character class; at the end of each
adventure Istus modifies the abilities of every member of that class (DM and
player notes are provided) and surprise, surprise, by the end of the
campaign everyone is 2nd Edition!"
There are no distinguishable printings between modules, other than the cardboard hanger for WG4.
WG4 Forgotten Temple of Tharizdun
Jeff Philbrick for the scan of the Second print of WG4, and to
Newman for the scans of WG6, WG10, and WG11.
Values for the Second print of WG4 Forgotten Temple of Tharizdun assume the cardboard header is present and intact. Since the cardboard is attached to the shrinkwrap, only the SW value here is relevant.
WG7 Castle Greyhawk and WG12 Vale of the Mage sell for absurdly high prices (comparatively). No particular reason, that we can see.
