A chronological era adopted by the Twenty-second Known Universe Standards Convention convened by order of Emperor Haereus II. The demarcation for the start of the era was the signing of the Tripartite Pact on Ventorum 4 in 16190 CE which established the balance of powers for the Imperium. The Tripartite Pact is considered by most Imperial historians as the beginning of the current Pax Galactica.
