The Ronin was the alias used by a male human former Sith who wandered the far edge of the Outer Rim Territories in the aftermath of the Sith rebellion. He would later be nicknamed as Grim. The Ronin had begun the rebellion as the Dark Lord of the Sith and led the Sith armies in battle after they broke away from the Jedi clans, seeking to control their own destinies and end the cycle of never-ending wars between rival feudal lords and their Jedi knights. The lords formed alliances as they sent their Jedi to battle the dark lord, his witch, their forces, and the Sith demons that the witch resurrected after their deaths. However, the dark lord grew disenchanted with what the Sith became during their rebellion and turned on his followers, ending the rebellion. The dark lord renounced the Sith, shed his former identity, and became the Ronin. After the rebellion failed, the former rival lords led a revitalized Empire that ruled much of the galaxy.
