The Stars Ascendancy, also known as the Tauren Ascendancy, or simply the Ascendancy, was created shortly after the fall of the Seresian Confederacy at the height of the war known as the Great Tauren War between five warring factions and resistance groups within the Midtaura Sector; the Aiurlan Imperium, Gadian Sovereignty, Kal-Mari Protectorate, the Seresian Confederacy, and eventually the Tauren Ascendancy. It is a stellar empire of seventy-six planets, five core worlds called the Nexus Worlds, seventeen mid-worlds called the Prime Worlds, and fifty-four frontier worlds known as the Terminus Worlds. It is ruled by the Diadem who resides on the capital world of Taura.
