The War in Heaven—a wide-ranging conflict between the immovable Great Houses, the renegade Faction Paradox and other major powers. All of them possess time-travel technology—and all of them are trying to usurp various points in history, thus erasing their opponents from the timestream. Marking the first five decades of the cosmic-spanning conflict, The Book of the War is an A to Z self-contained complete guide to the Spiral Politic, from the beginning of recorded time to the fall of humanity. This book chronicles the rise of the Faction as a renegade House, the creation of a living timeship named Compassion, some brutal battles across all of time and space and more.
