In this system-agnostic Sci-Fi supplement and love-letter to Mushishi by Yuki Urushibara, your characters play as frontier doctors called Kaichū-Shi or Parasite Masters. 

They'll exploring dark forests and researching parasitic organisms, known as Kaichū,  that exist in a classification somewhere between plants and insects. Heal colonists and blue collar workers who fall sick with mysterious ailments, exhibiting symptoms that vary from minor to life-threatening.

Many of the organisms are only visible when viewed through specific spectrums of light. Some only partially exist in this universe. When viewed, they are often semi-corporeal, ethereal creatures that bend light around them as they float and crawl around.

To play you'll need: 

  • This Pamphlet
  • A set of polyhedral dice (specifically d10's)
  •  The TTRPG of your choice

The digital download includes:

  • A Letter-sized Pamphlet PDF and PNG
  • Printer-friendly version
  • Creature and Scenario Generation
  • Short Settlement description and topological map

CW: This module contains elements relating to sicknesses and treatments and may not be suitable for all audiences

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.
