Zone four was a portion of the Fervse'dra asteroid belt that surrounded the Mid Rim world Bothawui. Zone four was located between zone five and zone three. During the Clone Wars' Battle of Bothawui in 22 BBY, General Grievous of the Confederacy of Independent Systems ordered his fleet of Munificent-class star frigates to pass through the asteroid field in a push against Jedi General Anakin Skywalker's fleet defending Bothawui for the Galactic Republic. In his push forward, Grievous's fleet passed through zone four. On the bridge of Skywalker's flagship, the Venator-class Star Destroyer Resolute, Resolute command tracked the Separatist fleet's progress through the field via screens, including its movement through zone four and into zone three. That movement was reported aloud by one clone trooper monitoring one such screen. Unknown to Grievous, Skywalker had hidden All Terrain Tactical Enforcers within the asteroids: by passing through, Grievous was outflanked, leaving his fleet to be destroyed.
Zone four appeared in "Downfall of a Droid," the sixth episode of the first season of the animated television series Star Wars: The Clone Wars, which aired on November 7, 2008.
