Product History
L3: "Deep Dwarven Delve" (1999) is the third adventure in Len Lakofka's Lendore Isle trilogy. It was also the final official adventure for first edition AD&D, released a decade after the line ended. It was published in August 1999 as part of the Silver Anniversary Collector's Edition Boxed Set.
The Silver Anniversary Collector's Edition Boxed Set. The Silver Anniversary set celebrated the 25th anniversary of Dungeons & Dragons (1974). It was printed in 5000 copies and sold for $59.95 (about $80 in contemporary dollars). Most of the contents were reprints, including the J. Eric Holmes Basic Rulebook (1977); B2: "Keep on the Borderlands" (1979); the three "G-series modules," G1: "Steading of the Hill Giant Chief" (1978); G2: "Glacial Rift of the Frost Giant Jarl" (1978); G3: "Hall of the Fire Giant King" (1978); I6: "Ravenloft" (1983); and S2: "White Plume Mountain" (1979).

The boxed set also contained two new books: a history of TSR and a "lost" adventure: "Deep Dwarven Delve."
The Lost Adventure. L3 was originally commissioned by TSR around 1979 as part of a three-adventure trilogy. It was submitted by Lakofka to TSR alongside L1: "The Secret of Bone Hill" (1981) and L2: "The Assassin's Knot" (1983), around 1980. And then it sat around for 19 years.
The problem was reportedly the changing political tides at TSR. Following the 1985 departure of Gary Gygax, Lorraine Williams is said to have purposefully cut out Gygax's friends and supporters. Thus Dave Arneson's Blackmoor adventures came to an end, and the third Lendore Isle adventure was never published by TSR.
The Found Adventure. Though the book itself reports that the adventure had "lain unseen and forgotten in the TSR design vault," in July 1999 Sean K. Reynolds reported a different story. He said that all of TSR's copies of the adventure had been "lost or destroyed" over the years. The adventure (apparently) resurfaced only when Lakofka found a copy around his house and sent it to Roger E. Moore in 1997 - possibly due to the changing political tides at TSR, for Wizards of the Coast was at that time involved in buying out Lorraine Williams. Moore then passed the adventure on to Reynolds in 1998.
Wizards of the Coast decided to publish "Delve," but the editors thought it needed "depth and clarification" to bring it up to modern AD&D standards. Lakofka was happy to oblige and produced a new version of his adventure… which Wizards again lost. Lakofka says that that he didn't hear about the loss until after "Delve" was published, by which time a number of Wizards developers had stepped in to do the required expansion for the adventure.
In the end, Lakofka says that "Delve" is about 80% comprised of material he'd turned in two decades earlier. Though L3 was published as part of the Silver Anniversary Collector's Edition, Wizards had also considered releasing it as a free PDF or publishing it in Dragon magazine.
A More Typical Adventure. The two previous Lendore Isle adventures were both very atypical adventures for early AD&D, with a focus on wilderness and towns and even a murder mystery in L2. Conversely the Moria-like caverns of L3 are a fairly standard dungeon crawl.

The Original Campaign. Like all of the L-series adventures, "Deep Dwarven Delve" was drawn directly from Lakofka's own Lendore Isle campaign. He says he created it when he "decided to go DOWN below the complex of rooms currently occupied by orcs, ogres, and a troll or two." Dwarves - like those who founded the "Delve" as a mithril mine - had long been an important element in Lakofka's home campaign, which had also included a six-month mini-campaign centered on freeing dwarves in another world from thralldom; this in turn led to Dobfur, an 8th level cleric PC, becoming a High Priest of dwarves for the Suel god Fortubo.

Lakofka is also known to have run "Deep Dwarven Delve" at GenCon XII (1979).

About the Creators. Lakofka continued working with TSR until 1986, writing his "Leomund's Tiny Hut" column for Dragon, but afterward disappeared from the industry. In recent years, he's returned to write a pair of huge Lendore Isle supplements (for Dragonsfoot): L4: "Devilspawn" (2010) and L4C: "The Lendore Isle Companion" (2010). He also submitted "L5" to Dragonsfoot in 2010 or earlier, but it has not yet seen publication.
Lakofka has also written articles for The Oerth Journal and more extensively for the Footprints fanzine.

We (Wizards) recognize that some of the legacy content available on this website does not reflect the values of the Dungeons & Dragons franchise today. Some older content may reflect ethnic, racial, and gender prejudice that were commonplace in American society at that time. These depictions were wrong then and are wrong today. This content is presented as it was originally created, because to do otherwise would be the same as claiming these prejudices never existed. Dungeons & Dragons teaches that diversity is a strength, and we strive to make our D&D products as welcoming and inclusive as possible. This part of our work will never end.

So it says it's a B&W print. Will the cover still be color or not?

Scanned image
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.
