Post–Great Hyperspace War counterinvasion

Sometime after the second battle of Korriban, Galactic Republic Supreme Chancellor Pultimo authorized a post–Great Hyperspace War counterinvasion of the Sith Empire centered on the Sith Worlds of the Stygian Caldera and outlying Sith colonial holdings elsewhere in the galaxy.

This period of Sith history immediately following the Great Hyperspace War was characterized by internal civil conflict, rampant disease, famine, and ritual mass-suicides among the surviving Sith-blooded remnant of the Empire. These events served as the backdrop to the joint Jedi-Republic counterinvasion of the Empire, a campaign aimed at assuring the complete destruction of the Empire and any vestigial threat it posed to the safety of the Republic.

Though some Sith survivors continued to oppose the Republic militarily, most refugees fled into exile on outlying Sith colonies like Ambria, Thule, Tund, and Vjun or joined the Sith exodus as members of Vitiate's exile fleet bound for the forgotten colony of Dromund Kaas. In addition to these diasporas, a handful of vestigial Kissai and Massassi communities persisted in isolation on Korriban well into the Old Sith Wars period.
