Cthulhu Hack: Forgotten Duty


A visit to the University of Navarra—located in Pamplona, Spain—in search of a rare book—the chronicles of a monk who claimed to have witnessed visions of other worlds—leads to a grim investigation.

Forgotten Duty is a short investigation—probably 6 - 8 hours of play—written for Cthulhu Hack but playable with any system geared toward Lovecraftian horror. Set in modern-day northern Spain, the investigation has the potential to set the starting point for a wider campaign. It also links loosely into other earlier adventures, providing the potential to run into or from other investigations.

The adventure includes:

  • a 28-page adventure, including deep background, timeline, GM guidance, non-player character write-ups and maps of locations—to supplement uses of Internet-accessible maps for more general reference into the area in and around Pamplona
  • a page of tables for randomly generating authentic names for non-player characters, as well as mannerisms, personality traits, and quirks to make them memorable
  • a 3-page section of handouts, including non-player character portraits
  • the PDF is bookmarked and cross-linked
  • includes character art by mirandemia and a map by Patrick McGill

While you need the for Core Book to handle the baseline mechanics, you could use the investigation with any other system or run the whole thing as a story-driven encounter with unnameable cosmic horrors.

Publisher Note: This investigation is written for the 2nd Edition of Cthulhu Hack. While compatible with 1st Edition, there are some changes that will require additional work by the GM.

Will there be a preview for the file?

I must have missed that setting when I updated the files, as it was set previously. It has now been restored and offers access to the first five pages - although the Quick Preview seems to show a black first page, it's fine in the Full-size Preview.

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.
