The Emperor or Empress of the Terran Empire, also known as the Terran Emperor or Terran Empress, was the absolute monarch of the Terran Empire in the alternate mirror universe, serving as head of state, head of government, legislative authority, commander-in-chief of the Terran Armed Forces, and final judicial authority all in one.
History[]
The Terran Empire was formed some time prior to the 22nd century. By the 2150s the Empire and Emperor’s powerbase was at risk due to a significant uprising in conquered races, who had formed a rebellion that the Imperial Starfleet was hard-pressed to contain. Eventually, this rebellion was destroyed when Jonathan Archer of the ISS Enterprise managed to procure the USS Defiant, a Federation starship from our universe's 23rd century, and used it against the rebel forces. However, Archer was poisoned, and the Defiant, the most advanced starship in that continuum's known space, fell into the hands of Hoshi Sato , who took the vessel to Earth and declared herself Empress.
Empress Sato I later married Andorian General Thy'lek Shran in order to solidify her powerbase and appease the Andorians. Eventually, she was forced to kill Shran, forming an alliance with T'Pol of Vulcan. She released the Vulcans from bondage and gave them nearly partner status within the Empire to Terrans. As part of her ongoing mechanisms, she resurrected Archer. Empress Sato I went on to sire a dynasty that ruled the Terran Empire for centuries.
