EX1 Dungeonland (1e)

Selected Option:
As adventurers, you may think you have seen everything: certainly your skills have brought you through unimaginable dangers. But now you suddenly find yourself in a place unlike any through which you have traveled: astounding, dangerous, and even amusing things confront you as you journey, both indoors and outdoors, through unique and wondrous realm of Dungeonland. 
This adventure was first conceived by E. Gary Gygax as part of the Greyhawk Castle dungeon complex and has been the source of challenge and fun for many skilled players of the Advanced Dungeons & Dragons game. It is finally available to all players and can be added to your existing campaign with ease.

"Dungeonland" is also designed so that it may be used along with its companion scenario, EX2: "The Land Beyond the Magic Mirror." Still, "Dungeonland" may easily be played on its own, and should offer hours of excitement in its strange landscape!
Product History
EX1: "Dungeonland" (1983), by Gary Gygax, was the first look into Castle Greyhawk, sort of. It was published in 1983. The "EX" is code for "Extension"; at one time the code "GC" was instead being considered, presumably for "Greyhawk Castle."
Sources. "Dungeonland" is based on Lewis Carroll's Alice's Adventures in Wonderland (1865). Gygax wasn't the only author to create a Wonderland-esque dungeon. Don Turnbull's version of the same can be found as "Alice in Dungeonland" in White Dwarf #4 (December 1976 / January 1977).
About Castle Greyhawk. Gary Gygax probably created Castle Greyhawk in late 1972, taking the idea of exploring dungeons beneath a castle from Dave Arneson's own Castle Blackmoor. Castle Greyhawk was thus perhaps the first actual D&D adventure location - which makes it all the more surprising that in the decade afterward, Gygax never produced a Castle Greyhawk supplement for TSR.
He offered hints of Castle Greyhawk's contents as early as Supplement I: Greyhawk (1975), when he mentioned the dungeon's "living room" and the fact that the dungeons contained a fountain of endless snakes. However, it wasn't until Gygax produced the World of Greyhawk Folio (1980) that he finally committed to detailing D&D's primordial dungeon, saying in The Dragon #35 (March 1980) that he was now hoping to produce "a huge map of the City of Greyhawk, modules based on the original Castle Greyhawk, and a series of offerings which depict the Elemental Planes of Greyhawk."
None of those ever come about. However, before he was forced to leave TSR, Gygax did manage to produce three adventures based on "demiplanes" - which were strange places that you could get to from Castle Greyhawk. EX1: "Dungeonland" (1983) and EX2: "The Land Beyond the Magic Mirror" (1983) detailed the first of them.
The Origins of Dungeonland. Gygax first ran "Dungeonland" for his original Castle Greyhawk campaign "after about a year of play," which would have put it in late 1973 or early '74. Gygax's players returned to Dungeonland many times over the years, among them future TSR luminaries like Ernie Gygax, Rob Kuntz, Terry Kuntz, Don Kaye, Skip Williams, and Brian Blume.
Gygax later ran "Dungeonland" at conventions, once even hosting Dr. Joyce Brothers!
(Not) Expanding Greyhawk. Though "Dungeonland" is one of the few published adventures actually based on Gygax's original Castle Greyhawk game, it does very little to expand the world of Oerth because all of the actual adventuring happens in other realms.
The Adventure Continues. The world of "Dungeonland" connects directly to that of "The Land Beyond the Magic Mirror," and the two adventures can be played together.
About the Creators. Around 1982, Gygax had a considerable burst of creativity that resulted in Monster Manual II and four adventures all deeply rooted in Greyhawk. "Dungeonland" was the next-to-last of them.

Still one of my favorite adventures. Gary Gygax really had a knack for writing great modules. Granted by 1983, when this was published, it's hard to know how much of it he wrote himself. It does have his trademark verbiage and flavor though. I also love Timothy Truman's illustrations in this.

This one was a "funhouse" adventure, the kind that is rarely written anymore as they are kind of silly and challenge the player more than the character. Recommended for anyone who just wants to have some good old fashioned fun at the gaming table, and isn't too attached to their character.

Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
