War Era universe

The Book of the War described the state of reality during the War in Heaven as the "War Era universe", viewing it as distinct both from the pre-War version of reality, and what would follow it. However, it did not correspond to a single state of history, but to an entanglement of them: the timelines of all the planets in the Spiral Politic were constantly rewritten for as long as the War lasted.
