Spies Below the Moonsea Header Image

New allies in the Underdark have emerged and are working to liberate drow-taken slaves from around the Moonsea. Key to this endeavor is finding a safe and secret passage between the Underdark and the surface. Rumors tell of such a passage deep within the abandoned Axcelon Diamond Mine. Yet the passage is the least of the treasures and dangers that the mine holds.

A Two- to Four-Hour Adventure for Tier 2 Characters. Optimized for APL 8.

  • Full colour illustrated PDF with a separate print-friendly version

  • Reference Maps in separate gridded or gridless files for easy VTT integration
  • Sights Below the Moonsea: A Guide to the Zethlentyn Protectorate - this short lore supplement is included with all Zethlentyn-related adventures.

Rules Edition(s)
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.
