As a hierarchical society, the Dominion is ruled by founders who are worshiped as deities by the rest of the empire. Among the founders are the Vorta, who are commanders, diplomats, scientists and administrators. The rank and file of the Dominion military are Jem'Hadar, genetically engineered soldiers bred for obedience and combat.
The Dominion's influence spans thousands of worlds, many of which are entity species. This immense power in the Alpha Quadrant was unknown until the discovery of the Bajoran Wormhole. Their introduction led to tension, diplomatic intrigue, and ultimately a full-scale war known as the Dominion War. This conflict had a huge impact on the political landscape of the Alpha and Beta Quadrants, demonstrating the Dominion's ability to be a formidable force in the universe.
The Dominion came to power without brutality. Races identified as threats were exterminated, while others deemed beneficial were enslaved. The Jem'Hadar, created as a warrior class for the Dominion, and the Vorta, who served as trustees, both contributed to the calculated expansion. Their unwavering loyalty to the shapeshifters they revered as "gods" made these races very important to the Dominion government.
After the discovery of the Bajoran wormhole, attention shifted from the Dominion to the Alpha Quadrant. Initial contact was fraught with tension and culminated in open hostilities and eventual full-scale war with the Federation and its allies. The Dominion War, famous for the Battle of Cardassia, demonstrated the brutal efficiency and military prowess of the Dominion.
The war reached a critical point when the Cardassians, originally allies of the Dominion, turned against them. The turn led to the Battle of Cardassia, a desperate show of Cardassian resistance that hastened the end of that conflict. The Dominion eventually relented and agreed to the Treaty of Bajor, marking a turning point in Dominion history and the beginning of a new era of tentative peace. This period of Dominion history was a testament to their tactical acumen, immense ingenuity, and dogged commitment to order that remains an integral part of their identity.
The Founders Planet is deep in Dominion space, hidden within the gaseous composition of the Omarion Nebula. It's a rogue planet with limited land mass, with a vast ocean in the gelatinous state of the founders.
The Dominion member worlds of Karemma and Vorta are unique aspects of the Dominion's geography. An economy-oriented society, Karemma lives on a densely populated city planet filled with impressive architecture, dominated by trade and commerce. In contrast, the Vorta's homeworld is a peaceful, forest-like planet, in keeping with the Vorta's origins as forest-dwelling creatures.
The Jem'Hadar, the primary soldiers of the Dominion, were raised on the many asteroids and heavily fortified structures scattered throughout Dominion space.
This geographic diversity reflects the multifaceted nature of the Dominion as an interstellar realm with many ecosystems, societies, and architectures.
