Black Knights

The Black Knights were an alliance of Sith forged together by the Dark Underlord on Malrev IV. The organization was created roughly 250 years after the death of Darth Ruin, and suffered the defeat of their leader at the hands of Jedi Master Murrtaggh. The Underlord's Zeltron general lead the defense against a simultaneous assault on the Black Knights Malrev IV fortress, a diversion staged by Mandalorian mercenaries to distract from the Jedi assassination attempt on their leader. The diversion was a success and the Black Knights' leader fell.

The group's fate in the aftermath of the battle is unknown, although it can be assumed that the organization dissolved, most likely violently, after their leader's death.
