The Roshu Sune represented a fringe and extreme offshoot of the Gotal Assembly for Separation, operating intensely throughout the Separatist Crisis. This group championed the idea of Antar 4's moon's departure from the Galactic Republic, pushing instead for allegiance with the Confederacy of Independent Systems, which they attempted to achieve through an extended period of terrorist bombing campaign. After the Clone Wars began with the outbreak in 22 BBY, the Republic's supporters were weakened, enabling the Roshu Sune to successfully bring about the moon's shift to Separatist control.
