Product History

"Castle Caldwell and Beyond" (1985) by Harry Nuckols was the ninth Basic Set adventure, and it marked the end of the classic sequence of Basic modules that had run for six+ years. It was published around June 1985.

The adventure was named for artist Clyde Caldwell, who also supplied the cover. There was originally a character in the adventure named Clyde Caldwell; TSR Legal didn't like that, but naming the Castle for him was apparently fine.

Mini-Adventures. "Castle Caldwell" stands out from the rest of the Basic adventures (and from the rest of TSR's D&D adventures to date) because it's actually a collection of five mini-adventures. The first two, depicting a castle and some dungeons found beneath it, are somewhat closely connected, but the rest are pretty loose. Why did TSR decide to go in this direction? It's because "Castle Caldwell" came in as an external submission, which was pretty rare at the time, and this is the format the author had used. Still, TSR would have much more success with mini-adventures when they refined the idea to a very simple core in their Books of Lairs (1986-1987, 1992-1993). They'd also start publishing more anthologies like "Caldwell" around 1988.

The End of Basic. In June 1985, when B9 was released, TSR was in grave financial peril. That same month, Unearthed Arcana (1985) was also published; it's the book that's usually credited the most with saving the company (though there were many factors, also notably including Oriental Adventures, the Dragonlance saga, and Marvel Super-Heroes). Afterward, as TSR climbed out of their hole, they started cutting some of their less successful lines. Thus the Conan (1985), Indiana Jones (1984-1985), and Star Frontiers (1982-1985) RPGS all came to an end. And so did regular adventure support for the D&D Basic Set - not necessarily because it was unsuccessful, but instead because there was already a whole lot of it.

The first nine B-series adventures were allowed to go out of print, and then replaced with a compilation of the best bits: B1-9: In Search of Adventure (1987). Adventure support for the Companion (1984-1987) and Master (1985-1987) also lines ended around that time, after which TSR's D&D focus moved to setting books for the Known World (1987-1989)

Three more Basic adventures were published much more sporadically. B10 (1986) originated with TSR UK, while B11 (1989) and B12 (1989) were a pair of new introductory adventures that indicated a brief attempt in the late 80s to revive the Basic line.

About the Creators. There's long been speculation that Harry Nuckols was a pseudonym (it certainly sounds like one!), and a few different possibilities have been offered for the "real" author. However, editor Michael Dobson asserts that "Castle Caldwell" genuinely was an external submission, not something written pseudonymously by TSR staff, and that Harry Nuckols was, as far as he knows, the author's real name.

Is Harry Nuckols a pen name?

Unlike the description, this module does not contain 5 exciting adventures. Instead, it contains 5 rather mediocre dungeons. They can work to fill out locations within a broader campaign - map-space fillers. But this is among the worst of the B series.

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.
