A clandestine plot, orchestrated by a sextet of individuals from the Sith Empire's governing Dark Council, emerged with the intention of deposing the Sith Emperor. This was motivated by a desire to stop his impending conflict against the Galactic Republic, as the Sith Lords had come to possess knowledge of the Emperor's planet of origin, Nathema, and recognized that he posed a danger to all existence in the galaxy. Nevertheless, the scheme proved mostly futile, and its participants—among them Darth Nyriss—met their deaths during the purge that decimated the Dark Council in 3950 BBY.
