To play within the Zone, players must first understand the design of the setting. Inside the Zone does a great job of describing its highly efficient structure. But the book does more than describe its physical setting. Layers of religions, Kults and politics intertwine with one another throughout the book. It is almost as if you are a god watching the inner workings of Zone society. The book is a must-read for anyone who wishes to play in the Zone.

So Obsidian begins its underlying premise, written as if it were a great, literary work. The philosophy is blunt and unrepentant. Humans are born as parasites in the universe of “The Sheol.” Daemons, pre-humanity, originate as harmless creatures. Greed, perversion, hate and corruption, all byproducts of human evolution, warp a delicate balance of co-existence within the “The Sheol.” These negative energies turn the daemons into the archetypes we think of today. God, or “The Divinity” in Obsidian’s universe, then separates the warped plane from Earth into nine Circles in an attempt to prevent the darkness from spreading.
