Neo-Sith Empire

The Neo-Sith Empire, also known as the Last Sith Empire, was an Empire that existed during the waning years of the Old Republic and the dawn of the Galactic Republic. It was the last incarnation of the Sith before the near-permanent destruction of the Order in 1032 BBY.

Formed by four dark-side sisters after escaping Mandalorian imprisonment at the end of the Mandalorian-Jedi war. After their escape, the sisters formed the Sith Quadrumvirate and began the final Jedi-Sith war sometime before 1054 and 1048 BBY. The Empire managed to bring the Republic to the brink of destruction, however, a temporary alliance formed between a fringe group of Mandalorians and Jedi led by Tarre Vizla. The alliance pushed back against the Empire and, in 1032 BBY, the final battle was fought on Moraband. However, the alliance's work would be done for them as Darth Syto and Darth Echdys would betray Darth Kaenus in a power grab. The Sith would then dissolve into chaos and infighting while the alliance would eliminate the remaining Sith

The only Sith that would survive would be Darth Bane, who would live on to create the Rule of Two.
