Underport: Abyssal Descent

Watermarked PDF

Underport: Abyssal Descent, a vintage mega-dungeon nearly 4 decades in the making. Originally written incrementally during RPG's early years between mid-1978 and late 1981, the style was swords & sorcery focused on heavy fighting action.

Now there are more than 250 individual, detailed encounters on 9+ dungeon levels plus a small pirate village and 2 underground keeps. Levels of difficulty range from 1st to perhaps 16th or 17th for a party of 5 or more adventurers. However, these are not "game balanced" encounters and players must measure when to cut & run. Revel in the chaos with an artifact based from the Wild West era of The World's Most Popular Role Playing Game!

(Written Product is formatted to print 2-sided in Adobe Reader's "booklet" format, but for best presentation leaf edges would need to be professionally trimmed by machine at a print or copy shop carefully so as not to trim text close to the edge. Maps are at a higher resolution to be printed separately on at least letter-sized paper)

***Please Note this product was edited to be compatible with a version of rules based on System Reference Document v.3.5 and will require some creative adjustments to run with the current Advanced Knights of the All Mind rules based on SRD v.5.1.

Original electronic
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.
