Deceptively centralized, the Gallant Dominion is, on paper, a sub-confederacy inside the Union itself. Consisting of a network of aligned worlds ruled by noble houses and merchant families and connected by marriage alliances, the reality is that the entirety of the Dominion is fundamentally controlled by the house of Keita, with its cadet branches holding prime place on individual worlds. Though the Gallant Dominion is the smallest of the Union Astartes regions it boasts one of if not the strongest economics of them, being the dominant power in interplanetary shipping and mercantile ventures, a fact that gives them power despite their relatively small size. Individual worlds are left mostly to their own devices, shipping is patrolled by the swift and large Corsair fleet, and even tributes and taxes are kept low, loyalty enforced via marriage and coin. Tension between the Gallant Dominion and the other Union factions has always been high, and are often kept because of the so called Corsair Secessions, a number of worlds that lay officially beyond the borders of the Union and also that are not ''de jure'' parts of the Gallant Dominion, instead existing as merely ''de facto'' holdings. These are varied worlds, some of which that still claim public allegiance to the Imperium, but they are isolated and fall under the sway of distant merchant princes with ease. Even with these worlds, though, the Corsair's holdings remain the smallest of the Union, and they rely upon their economic might to give them outsized say in the the political realm.
