The broad sweep of history is divided, roughly, into 10 eras. These eras are largely based upon the rise and fall of Humaniti and their empire of the stars. While other races, particularly the other Major Races, may have a differing division of eras, the Imperial Encyclopedia uses the Humaniti-centric one.
