There is a book that has only been spoken of in terrified whispers behind closed and locked doors. It is said that only seven people have ever seen this book over the course of all of human history and only four have opened it. Only one man has ever read it.
The book…isn't really a book at all, but a machine. The binding opens and locks, with a grate in the center where the pages can slide through. When the book is opened, and the pages lie flat, they can be shifted into different positions. Each page is made of metal, the words embossed on it. On each edge of the page is a specially cut design; no two designs are the same.
It is said that one must find the proper arrangement of each of the five hundred and thirty six pages and go to the "Rock of Chaos", where time is the only constant. It is a place of madness where lightning moves from all directions and the sky itself burns with an insane blue fire. The Rock is the face of an immense cliff, the bottom of which can never be seen by mortal eyes lest they go blind and mad. Somewhere on the face of the rock there is a single hole, an opening just the right size for the book. Properly aligned, the book must be brought to this "keyhole" at the exact moment specified by the stars and spoken of within the book. One places the book in the hole at the exact moment, and unlocks the Chaos Chain. This is a chain of pure ether, which runs from our world deep into that of the Void, and there, at the Throne of Darkness, the Chain binds that dark soul who rules the Void and would wreak apocalypse on us all: Unenon, the Blind Angel of Darkness.
What the book says…well, only one man ever read it, and it is said that he locked himself in his room for thirty days before emerging, tome in hand, and swore to take the book to the ends of the earth before he died. He has never been seen or heard from since.
