From the description:
"End of Small Santuary" is a campaign for the tabletop roleplaying game Pathfinder, written by Katherine Graci and Samantha Gagnon. The campaign takes place in an alternate timeline where the internet never gained traction in the 90's, and instead magic was "solved" scientifically and took its place in society. A global arcanic arms race ensued, ravaging the planet and tearing the fabric of reality.
The 76 page book includes a player's guide to the setting, new rules for Arcanics and Tulpas (including 3 new classes), and a five part adventure. Everything in this book uses the Pathfinder 1E rules in combination with the Psionics rules for Pathfinder published by Dreamscarred press.
The campaign is loosely based on Katherine's band's album "Halos."
