Jyvus
this was one of the many orbital cities established around the planet Duro. During the height of the Clone Wars, Separatist forces under the command of General Grievous attacked Jyvus and overwhelmed its defenses. This gave Grievous access to the controls for the planetary shield that protected Duro, which was prompted shut down. From this staging point, the Separatists were able to launch orbital bombardments of Duro's surface.
