The separatist group known as the Bosthirda separatists consisted of Human individuals. They sought to break away from the reconstituted Sith Empire, with their target being the homeworld of Bosthirda. However, their actions were merely a facade, as they were actually controlled by the Dark Councilor Darth Xedrix, who manipulated them for his own schemes. Ultimately, in 3954 BBY, their existence was exposed, leading to their complete destruction at the hands of Sith Lord Scourge and the forces commanded by Dark Councilor Darth Nyriss.
