Castle Greyhawk The original campaign dungeon, designed and run for decades by Gary Gygax himself along with Rob Kuntz. Most of the dungeon was essentially unpublishable, as it was in the form of Gygax’s own terse notes and maps, but attempts have been made over the years, with and without Gygax’s involvement. TSR published a module in 1988, but rather than being based on any of Gygax’s work, it’s a collection of jokey theme levels that are generally seen as a deliberate insult to Gygax after his departure from TSR. Naturally it is widely reviled. TSR made a more serious attempt in 1990 with for AD&D 2e; this module was updated in 2007 as for D&D 3.5. Starting in 2005, Gygax began publishing pieces of the castle through Troll Lord Games for their Castles & Crusades system. The Castle Zagyg modules (renamed since Wizards of the Coast owns the name “Greyhawk”) cover the Free Town of Yggsburgh (i.e.

The Free City of Greyhawk) and the “Upper Works” of the castle, plus a few other areas. These are now out of print, as Troll Lord lost the license after Gygax’s death, so finding them is up to you. Refer to this. Readers curious about the complex history of the ultimate megadungeon, and what is known about Gygax’s version, are referred to Allan Grohe’s exhaustive. Undermountain The megadungeon of the Forgotten Realms, Undermountain has seen many published versions. Unlike Gygax, Undermountain’s designer (and Forgotten Realms creator) Ed Greenwood never ceased his working relationship with TSR/WotC. Thus Undermountain is the signature megadungeon of official D&D.

Published versions include 2012′s for D&D 4e, for D&D 3.5, and for AD&D 2e, the Ruins of Undermountain boxed set, The Ruins of Undermountain II: The Deep Levels, and the Dungeon Crawl trilogy of the Lost Level, Stardock, and Maddgoth’s Castle. (All of these can be found used online. The original boxed set is highly recommended.) The dungeon has also seen play in video games, including the reviled Descent to Undermountain and the acclaimed Neverwinter Nights. Dwimmermount The brainchild of James Maliszewski of, Dwimmermount raised nearly $50,000 on Kickstarter from over a thousand backers.

Sep 29, 2009. Gygax was finally putting the whole thing on paper in official form, albeit under the alias 'Castle Zagyg', for the first time! Kuntz's 'Castle Zagyg: Black Chateau' (an introductory module), and Gygax's 'Castle Zagyg: Yggsburgh', a home town nearby the castle proper. BtBG Reader - The Pastel City.

Not sure how it’ll be made available to non-backers, but you can rest assured JM will have updates at Grognardia. You can see the Kickstarter page. Barrowmaze Created by Greg Gillespie, Barrowmaze is available in pdf, softcover, and hardcover formats. You can also buy hi-res maps separately in either black-and-white or awesomely old-timey blue-and-white. STONEHELL DUNGEON Michael Curtis’s Stonehell Dungeon was first released in 2009. It’s available in pdf and softcover at along with two supplements that expand the dungeon.

CASTLE OF THE MAD ARCHMAGE Few know Greyhawk better than Joseph Bloch of (a great gaming blog in its own right). Is his take on the granddaddy of all megadungeons, Gary Gygax’s Castle Greyhawk. CMA spans some twelve levels of old-school dungeony goodness, has been hailed as one of the best products of the old-school renaissance, and is available for free in pdf form (though word is that it’s going to be officially published by Black Blade). You can also nab hi-res.

Rappan Athuk Bill Webb’s monstrous Rappan Athuk has gone through two versions already:, and, both released in the early 2000′s for 3rd edition D&D. The to produce a new version of RA (statted for both Pathfinder and Swords & Wizardry) raised an incredible $246,541 to release an even bigger Rappan Athuk through Frog God Games (who swallowed up RA’s original publisher, Necromancer). Anomalous Subsurface Environment, the first part of a megadungeon by Patrick Wetmore (known as PatW on various forums), includes a long description of the history and situation of his dungeon, as well as the first level.

ASE is known for its gonzo attitude; set in a future Earth, it includes dinosaurs, super-science, and all sorts of whatnot. Numenhalla The in-house megadungeon of the blog, Numenhalla is built around the credo “Don’t be a boring person telling about boring things.” It’s rare to see a megadungeon spending so much time on setting, but the spend as much or more time on the gods, races, etc. Of the world as on the dungeon itself.

World’s Largest Dungeon Published by AEG in 2004, the weighs in at over 800 pages and at the time, was both the largest and most expensive roleplaying book ever published. Containing every monster included in the d20 SRD, the dungeon is designed to take characters from level 1 to 20 and includes over 1600 rooms. There doesn’t seem to be much support for it any more, but you can still buy WLD. Maure Castle was a location used in a campaign that ran for, and they later both worked on. This campaign, in its pre-commercial form in 1972-1973, was the seed from which much of the campaign setting and the Dungeons & Dragons game itself originated.

Castle Blackmoor details the 20 known levels of the dungeon including the first 10 levels as originally created by Dave Arneson himself. Designed to scale with varying party sizes and power levels, this incredible dungeon includes adventure material for character levels 1-20. Castle Whiterock Goodman Games is a complete campaign. Designed to take new characters to 15th level and fuel a game for years. Caverns of Thracia is a classic Judges Guild dungeon which was expanded and updated for 3.5 by Necromancer Games.

Tegel Manor is a 240 room Judges Guild dungeon which has been republished by Gamscience.

Greetings fellow Dfers, Like many and for more years than I care to admit, I wanted to run/play the real Castle Greyhawk, its dungeons and all the goodness it offered. Of course, things didn't work out the way we envisioned with the passing of Gary long before this project could be finished and shared with the gaming world. Jump back in time to 1974 when I was 11. I was introduced to Chainmail by my Uncle - whom was a historical war gamer and I dug the whole miniature thing right away. The next year my world was changed when D&D came out and my Grandfather bought it for me. My mom then married a real piece of work - my stepfather. He was one of those men whom was a pathetic excuse and dominated my mother and I emotionally, physically - the whole gambit. Eyecopia Serial.

In any case, D&D, and then AD&D saved my life quite literally. It kept me from spending most of my adult life in prison by focusing on a way to escape for a short time from him and the troubles I faced on a daily basis. I'm sure my story isn't unique, and it may seem quite sappy to some, but there is an epilogue to it I'd like to pass on: While attending a convention in the early 80's I had the opportunity to meet Gary for the 3rd time - and even saw a bit of one of the dungeon levels from Castle Greyhawk (which one I don't remember - wish I did). During a break between sessions, I saw him again and wanted to share this story with him.

As I finished, he smiled, grasped my hand ever so firmly and got a twinkle in his eye. Then he said 'Thank You!' So jump back to this year, and I still longed for Greyhawk.

I set my sights on the Upper Works - heck everything I could get my hands on that Troll Lords had done for this setting. After reading a ton of reviews about it online and coming into it with the mindset that it didn't have the dungeons that some wanted, I decided to track down a copy. I spent way more than I wanted, but it arrived yesterday. To say I'm excited and elated is an understatement. This has Gary's fingerprints all over it and it shows. So, Yggsburgh and Dark Chateau are on their way - all that is left to do is track down a copy of East Market Gazetteer and I have the kit and caboodle. Oh yeah, the dungeons, I forgot about them.

Well thankfully, Joseph Bloch over at has created The Castle of the Arch Mage and its been made available to download at his site. It connects perfectly to the Upper Works and is amazing. I took it to Staples, and had it printed in a set of spiral bound booklets single page so I could keep/make notes on each page. I even had the maps bound separately to make my life easier. Outside of booklets - note custom cover with MAPS written on it: Inside: So in a few weeks the Foaming Flagons will be starting their campaign in my world, and thanks to Gary, Jeff Talanian (Co-Author of the Upper Works) and Joseph Bloch - they will soon be exploring this wonderful collection.

You are missed Gary! Joe, Truth be told, I've been hesitant to give a review of your work - given every one I've read has been positive and fantastic. I'll only say: Everything has been melded together to blend with the Upper Works, and the simple descriptions on each level mimic what Gary did with his original. Not only does Castle of the Mad Archmage fit that style, this is the truest and I think, most fitting tribute to Castle Zagyg that could be done.

So now it falls to me to present this to my players in what I can only hope is an adequate method. Time as they say shall be the truth-bearer in all things. Whats the opinion of the Upper Works by those that have read it? Does it have an old school feel? Does it have a greyhawkian feel? Does it have a gygaxian feel?

It was written 25 years afters gygax's hayday, just wondering how much his style and imagination had changed There are tons of reviews online that speak about the Upper Works, and everyone I've read is positive. Most are taken from the standpoint that the reviewer was expecting the dungeons to be included with this setting. The two best reviews speak of the entire boxed set in detail, and are the reason I decided to find a copy. As I said in my OP, I entered this process from the standpoint of someone knowing what the Upper Works didn't have (i.e., the dungeons) and wanted to read first hand while looking in to Gary's mind and seeing a small piece of his original design.

In the end, Castle Zagyg: The Upper Works does have that old school feel. When I read various sections of it, its like picking up The Keep of the Borderlands and Dungeonland, while being thrown back 30 years in time. As a veteran of two campaigns in Greyhawk, it certainly does feel like it - mostly because there are phrases that Gary included that harken back to that setting. What I mean here is: Certain encounters have Gary written all over them. There are quirks, small little details that when you read them, the hair stands up on your arms because you've seen them in previous Gygaxian prose. What I take away from the Upper Works is this product is a rare glimpses into what I think Castle Greyhawk is and was, and while I know that not every single word came directly from the mind of Gary, there is enough here to make me smile and nod with enthusiasm.

Hopefully, that answers your questions adequately. Allan, Absolutely.

Your review is excellent, and covers everything I hoped for. As to your site, yes indeed I visit about once a week, checking your archives and reading over certain historical details. You should put the history into a pdf of some sort for those to download.its grand reading. As to the links, thank you.

I've been wanting to keep track of Rob's work and make sure I keep up on everything he's doing as it relates to Greyhawk. My little blog is now following all of your links that it can - so now I'm up to date.

***** I'm still waiting on Yggsburgh and Dark Chateau to arrive.so the last part to find is the East Side Market Gazetteer. In many ways, I'm in a very deep melancholy state at the moment. Bittersweet and yet my eyes are wide open to the possibilities that all of this material is presenting to me.

God, I sound old. BB, congrats on your buy! I did the same as you with Joe's COTMA, making the maps a separate book, though I printed all mine double-sided. The other change is that I used Richard Grave's 'The Mad Demigod's Castle' here: It's the storage room level, between the Upper Works and Joe's levels. I also combined the four quadrants of each level map into one and printed them on tabloid-size paper, though the scale is small. Here's my cover (just changed some type): Joe and Richard, thank you for making these available to the community!

ChrisL The pleasure was all mine, I had fun making it. If you're looking for some additional inspirational materials to use for your version of the Castle, you should also check out: - Axe & Hammer @ Yes, I am interested in Grendelwulf's blog, particularly this entry: In the lower half of the article, he presents a rather authentic-looking version of the Level 1 Storerooms including a map and an outline of fifty rooms. Corel Photoimpact X3 Activation Code Free more. Can any of you confirm that this material comes from Castle Zagyg: Upper Works, and if not, where? With a bit more fleshing out (such as treasures and dungeon dressing) I would happily use this for my 'own' Castle Greyhawk.

Rath's treatment of the Storerooms is very nice, and tempting to use as well! I think it is a bit of a crime to gamerdom that these materials should have such a low print run. I'd hope that one day Gary's original Castle Greyhawk would be available to 99% of the gamers out there, not the other way around! Very well stated Prespos. BB has shared with a few of us what he paid for The Upper Works, enough money to amass a sizable 1e collection in its own right. At this market price, most of the copies are in the hands of collectors who will probably never play it as a module. They won't handle the books nor roll dice on the unfolded maps.

I am glad BB has decided to honor Gary's last published work by playing it and enjoying it with his friends, the way it was meant to be.

Indeed I can verify this is the storeroom level from Castle Zagyg: Upper Works. What is missing from this map is the Mouths of Madness (multiple caves/caverns) and Castle Fortress Cellar.

A secondary booklet also contains an additional 20 pages of maps detailing the Castle Fortress, East Wall Towers, and Ruins of the Castle Precincts. I am glad BB has decided to honor Gary's last published work by playing it and enjoying it with his friends, the way it was meant to be. Sunday we continued a 1E ongoing Campaign in Myth Drannor, we finished up a bit early so attention turned to Upper Works.

The Foaming Flagons got to see the Maps (cursory glances) and were blown away by the amount of detail. All are excited to journey there and as one player said: you ready?

(drops 1st level character sheet on table quickly)- I am! I've had a slight setback on my home PC - need to pull data/files etc. Off of it and store them on my external HDS, then reinstall Vista - so I can't post images but I just received The City of Yggsburgh and Dark Chateau this evening. To be quick, I love the detail in Yggsburgh. The map that came with it is identical to that from the Geyhawk Folio - circa 1983 (turns out its the same artist) and while the city map is 'okay' - the recently released Yggsburgh map in PDF is certainly what I will use as a reference when the party gets there.

I didn't realize that Dark Chateau was written by Rob Kuntz. For me this is a real bonus and quite an honor to know their histories 30+ years ago continue in these early volumes of Castle Zagyg.

Lastly, Deo talked about the cost of Upper Works. He's correct, given I just saw a 32 module collection go on Ebay for a 1/3rd of what I paid. In the end, while my OP spoke quite honestly about my personal reasons for the purchase, this is also for my friends. The cost really wasn't the determining factor - it is the Flagons love for all things old school, our passion for mega dungeons, and the respect we all have for Gary. Deo, the auction in question: As to conversion - I'm simply using the appropriate monster from the Monstrous Compendium. When I won Yggsburgh and Dark Chateau, they also came with a hardbound copy of C&C's Player's Handbook and Monsters & Treasure.

Funny to open the Monsters book up and see familiar faces from the AD&D Monster Manual(s). I'll have to pull something together for a writeup on Myth Drannor - I'm a player in that campaign, and our esteemed DM is too busy otherwise to post something like this. I think it is a bit of a crime to gamerdom that these materials should have such a low print run. I'd hope that one day Gary's original Castle Greyhawk would be available to 99% of the gamers out there, not the other way around! I imagine it must hurt (having paid so much money and all) but one collector should do the right thing and 'share it' with the rest of the gamerdom. Although I suppose that to properly 'share' you must cut all the pages off (to scan them better) and no one in his right mind would do that, after having paid so much for it.

There was also a TLG produced.pdf of the set, I've heard it's not available for download anymore, [strike] but I am sure it's floating around somewhere. [/strike] EDIT: No, I don't have it and I don't know where to look. Some very diligent pirates tell me they have looked and come up dry.
