From Introduction:
DUNE: A Dream of Rain is a d20 System game based on the novels by Frank Herbert. While the game takes place on a galactic scale, most of the action is set on Arrakis, now the most important planet in the known universe. Important because it is the only known source of a spice that permits space travel, extends human lifespans and even allows humans to alter their consciousness.
The game is a world of wild adventure and political intrigue, where heroes battle with a lasgun in one hand and a knife in the other. Where a forgotten culture becomes one family’s only hope for survival and miraculous technologies expand the limits of human potential.
While psionic powers exist to a certain extent in the form of Prana Bindu training and the so-called “weirding way,” “magic” as such, does not. It is a well known science fiction axiom that any sufficiently advanced technology is indistinguishable from magic, but I draw the line quite clearly here.
