Synthetic Dream Machine: Eternal Return Key - CHROMADEMON EDITION


Synthetic Dream Machine:
Eternal Return Key

a psychedelic roleplaying game with dice and a referee


Strap on your surface battle suit.

Activate your pain projector.

Get on your grav speeder.

Raise your titanium hound rampant hexagon.

And ride towards the lie of civilization to discover why your corpsicle was revived in an alabaster cryopod. There is a lie there, and perhaps behind it is truth of the scratchy voices in your head.

Beware the noösphere demons. Beware your memories.

Something has gone wrong with your world.


This is the chromademon edition of Eternal Return Key, the art-full rules for psychedelic roleplay with the Synthetic Dream Machine system (formerly teased as S.E.A.C.A.T.).

This edition includes: 

  • SDM: the anti-canon rpg system formerly known as S.E.A.C.A.T. Rules for playing in a strange, trippy world like that of the Ultraviolet Grasslands(read manga-style, from back to front).
  • Eternal Return Key: a character generator for a PC waking up in a wasteland with no idea how they got there. Can serve as an alternate start for the Ultraviolet Grasslands and the Black City ((read BD-style, from front to back).
  • Pointyhelmet's New Body: a graphic novel detailing the adventures of the well-deserved hero Pointyhelmet and his trusted sidekick, the mighty wizard Poncho.
  • A map: somewhere strange and wide to start, east of the civilized world, between the big sun and the little sun.  The other side of the Circle Sea from the Ultraviolet Grasslands.

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.
