The pirate group known as the Ravagers operated from their base of operations on the planet Rishi, and they were a notorious pirate organization. Prior to the outbreak of the Galactic War by many Years, the Ravagers participated in the well-known Ravager Raids. As the time of the Battle of Rishi approached, Coratanni, who was Ruugar's lieutenant, overthrew the Ravagers' captain, Ruugar; subsequently, Ruugar sought assistance to eliminate Coratanni.
