An electrostatic gun was a type of energy weapon used by the Sith Empire. A large electrostatic weapon was mounted atop the People's Tower in New Adasta on the planet Ziost, and was designed as a last resort against major civil uprisings. During the Invasion of Ziost, Theron Shan modified it to be non-lethal, allowing him and his allies to free New Adasta's population from Vitiate's control.
