User Summary: A setting for GURPS Horror or GURPS Illuminati
The creatures of myth are real. The vampires, the warlocks, the shape-changers and dopplegangers, the ghosts and trolls, and more. They're real...they're here today...and they're organized.
The Cabal is the conspiracy, trade union, and mutual-assistance society that lets all these creatures survive in a world of hostile humans. If a demon needs a lawyer to keep the exorcists off his back... or if a little old vampire lady needs a bit of daylight muscle...who are they gonna call? The mortal-busters...the Cabal.
Written by Ken Hite, this book also includes a detailed system of Hermetic magic that expands the original GURPS magic system.
The Cabal can be a Patron for monstrous PCs or an antagonist for monster-hunters. This book includes a complete alternate (true!) history of the world, adventure seeds, occult cosmology, an assortment of artifacts and supernatural creatures, and suggestions for bringing horror and conspiracy into a variety of campaigns.
