Sometimes these domains connect, and the creatures in these domains can interact. Monstrosities can cross over from their domains and bring with them the physics and geometries of their home. Your Character has been recruited into a secret organization dedicated to protecting this Domain. You have begun your life of defending this Domain from terrifying monsters from beyond. This book includes the core rules as well as the introductory adventure for Level 0 Novice Characters so that the Characters can level up and advance to full Level 1 Characters… if they survive!
