History and background
During the Pacification Campaigns, Emperor Artemsus divided space into six regions, labeled them domains, and appointed an archduke over each of them. To each archduke, he assigned the continuing pacification of the domain’s many systems and their integration into the Imperium.
The domains were: Sylea (Core, Fornast, Massilia, Delphi), Vland (Corridor, Vland, Gushemege, Dagudashag), Gateway (Ley, Glimmerdrift Reaches, Gateway, Crucis Margin), llelish(Ilelish, Zarushagar, Reaver’s Deep, Daibei), Antares (Lishun, Antares, Mendan, Amdukan), and Sol (Dispora, Old Expanses, Solomani Rim, Alpha Crucis). Most of the domains were never totally absorbed into the Imperium
In 589, during the First Frontier War, a seventh domain was established-Deneb (Spinward Marches, Deneb, Trojan Reach, Reft) The intent was to appoint an archduke to be responsible for their supervision. However, the Civil War broke out before an archduke was appointed.
Following the civil war, the emperors expressed concern about individuals with powers equaling their own, so they moved to lessen the power of the archdukes in the Imperial government Because of this, no archduke of Deneb was never appointed. As a result, the domains came to have little practical significance. Each archduke did retain the power to create knights and baronets.
In the years after the Fourth Frontier War, and after the problems it presented from lags in communication, Emperor Strephon felt a strengthened archduke position could enable the Imperium to more quickly respond in defending the realm.
Against the protests and opposition of some prominent members of the Moot, Strephon reestablished the domain as a level in the bureaucracy of the Imperial Navy and to the Domain the ability to collect taxes. Strephon appointed an archduke of the Domain of Deneb: Archduke Norris.
The Ziru Sirka controlled most of Meshan and Mendan sectors, but they are entirely outside the bounds of the Third Imperium.
Gateway and Crucis Margin sectors are entirely outside the bounds of the Imperium and the Ziru Sirka.
