Cloud Empress: Rulebook


Start your journey into an expansive, Nausicaa-inspired fantasy campaign setting ruled by giant Magic Cicadas, for the Mothership Sci-Fi Horror RPG 1E. Unleash imaginative magic spells and harness ancient relics to survive the summer of the Century Brood. 

"Cloud Empress is a startling vision bursting with imagination and wonder. watt has pulled off something truly unique - both familiar and unsettling."

  • Sean McCoy, creator of Mothership
"Cloud Empress is unafraid to be subtle and quiet. Filled with fresh ideas and rooted in play, it is a deeply human work."
  • Luke Gearing, author of Hull Breach and Pound of Flesh

Cloud Empress is an expansive, Nausicaa-inspired fantasy campaign setting for the Mothership Sci-Fi Horror RPG. Cloud Empress places you in a world ruled by the patterns of giant magical cicadas. Cloud Empress creates a new Earth, thousands of years in the future inspired by Hayao Miyazaki’s Nausicaa in the Valley of the Wind, Frank Herbert’s Dune, and Hiromu Arakawa’s Full Metal Alchemist.

Is there a place to get the solo rules from the Kickstarter campaign if we missed it?

I don't know of a more imaginative, engrossing and thoughtful approach to a RPG. Ecological. Science. Fantasy. What else do you need to know? I mean, look at the art!

I enjoyed the six month campaign based just on the already fun early version. This final version is so gorgeous and even more complete, so excited to try and get another Cloud Empress game going soon, :)

Hey Nicholas, Cloud Empress is entirely stand-alone using this rulebook. A free introductory adventure, setting book and more will be released over the next two months to use with the Rulebook.

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.
