Sith Empire

The Sith Empire is one of two playable factions in the MMORPG game ''Star Wars: The Old Republic. ''Initially they were presented as a deadly and feared Empire, but as the game progressed, their threat level has been reduced as more powerful villains were introduced, turning the Empire into a more anti-heroic faction.

Beginnings
As the First Sith Empire crumbled at the end of the Great Hyperspace War, Darth Vitiate broadcast a message to the people of the Sith Empire ordering them to leave Korriban and flee to Dromund Kaas. As most of the other Sith Leaders were dead, they complied. The remaining Sith Ships fleet to Dromund Kaas, an abandoned and forgotton world, where Vitiate promised his people a bigger and more powerful Sith Empire that would overthrow the Republic and Jedi.

Over the next centuries, the refugees built massive cities and temples on Dromund Kaas and built a new army and navy. As their new homeworld was unknown to the rest of the galaxy, the Republic never suspected the true Sith survived. As the Sith rebuilt themselves, several rogue and Dark Jedi adopted the Sith Ways and created their own Sith Empires or factions including Exar Kun, Darth Revan, Darth Malak, and Darth Nihilus. However the Republic and Jedi defeated the Empires and factions of those Sith.

Return
300 years after the defeat of the Sith Triumvirate, Vitiate and his Dark Council decided the Empire was ready and launched his invasion of the Republic. After 28 years of war, the Empire was victorious, but they were only able to conquer half of the known galaxy. After the treaty of Coruscant was signed, the Sith began facing inner trouble, as many important Sith began fighting over power and backstabbing each other. In addition, several proxy wars were waged against the Republic.

Eventually a second war began and the Sith Empire began facing defeats and losing important political and military leaders. It soon became clear to the Sith that they were just as desperate as the Republic. On occasion, the Republic and Empire reluctantly teamed up with each other to fight enemies that threatened both galactic superpowers such as the Sith Empire of the traitorous Darth Malgus, the Hutt Cartell. the traitorous Dread Lord's and the Order of Revan. Durring the final battle against Revan, Vitiate revealed his true plans to destroy all life in the Galaxy, including those of the Sith Empire and the Dark Council declared him a traitor.

Eternal Empire
Vitiate returned however as Valkorion with his true trump card, the Eternal Empire which he had been secretly building behind the scenes while the Sith Empire was preparing for war on Dromund Kaas. Under the might of the Eternal Empire, the Republic and Sith Empires were overwhelmed and forced to surrender, with most of the members of the Dark Council killed or missing. The Sith reluctantly signed a peace treaty with the Eternal Empire that would allow the Sith Empire to remain independent, in exchange however, they had to pay heavy tribute of raw material and resources and live under arms limitation. (A similar treaty was signed by the Republic). Darth Acina, the sole remaining member of the Dark Council took up leadership of the Sith Empire as Empress.

However, neither the Sith Empire or Galactic Republic were willing to bow to the Eternal Empire and it's new Emperor Arcann and once again, reluctantly teamed up to form the Alliance, a rebel movement secretly backed and financed by the Sith Empire and Galactic Republic to overthrow the Eternal Empire and free the Galaxy.

Legacy
Eventually, by means unknown, the Sith Empire vanished from the Galaxy. It is currently unknown if it was overthrown or collapsed in on itself because of in fighting.
