The death of Palpatine and the destruction of the Sith Eternal had prevented both the rebirth of the Sith Order and the establishment of the new Sith Empire. A number of uprisings took place across the galaxy, causing the rapid collapse of the First Order. After Palpatine died, the remaining Sith Eternal both on the surface of Exegol and the Sith fleet were decimated.

Valkorion used the Empire's large fleet to battle both the Galactic Republic and Sith Empire on multiple worlds, a war in which, he sought to reshape the entire galaxy. The Emperor was eventually defeated by his secret granddaughter Rey and suffered his final death when she directed her grandfather's Force lightning back upon him. The Eternal Empire, also known as the Empire of Zakuul, was a dictatorial government founded by emperor Valkorion on the planet Zakuul sometime before the Galactic War of 3640 BBY. From the shadows, he formed the First Order through his creation Snoke to antagonize the New Republic and distract from his real plans, to build up an extremely large fleet of Xyston-class Star Destroyers, the Final Order, and use them to swoop in and conquer the galaxy once more, in an attempt to restore the Sith Empire. Following the defeat of the Galactic Empire at the Battle of Endor, which saw the destruction of the second Death Star, the resurrected Sheev Palpatine retreated into the Unknown Regions with a collection of his followers to rebuild his fleet.
