The Imperator was the supreme leader of the Imperialist Party, originally only in the Kyros sector itself, but later throughout the Galaxy. The Imperator enjoyed ultimate power and dictatorial authority, albeit only within the Party (the political leader of the Independent Kyros Sector of this time was the Lord Admiral Imperial). However, for Party members, Party doctrine was supposed to supercede secular law. The title was created by Evir Daal after his takeover of the Party, and he was the only legitimate holder of the rank. After Daal left the Party, the title was assumed by various high Party officials, including Arwyl Gudrin and Garet Jax, and the Party fractured into insignificance.
