Eternal Empire

The Eternal Empire is a large galactic government based on the planet Zakuul and founded by Valkorion. The Empire possesses a large fleet capable of battling both the Galactic Republic and the Sith Empire. It serves as the main antagonist organization in Star Wars: The Old Republic: Knights of a Fallen Empire.

History
Between the First Jedi Purge and the Great Galactic War, Sith Emperor Vitiate searched through the Wild Space in search of the Eternal Fleet, a supposedly unstoppable fleet of warships operated by sentient droids. His journey brought him to Zakuul, where he discovered a culture of superstitious humans who worshiped a group of deities called "Old Gods". Taking on the identity of "Valkorion", he unified the nomadic tribes of Zakuul into the Eternal Empire and installed himself as their Immortal Emperor. He formed a new Order of Force-users called the Knights of Zakuul who would rise above the light and dark sides of the Force. Soon the Eternal Fleet was located by the Scions, a subgroup of the Knights. The Eternal Empire soon gained control of the Eternal Fleet and the GEMINI droids that controlled them.
