Archa Sabis's Droid Army was a revolt that occurred on Coruscant, involving EVS Construction Droids, police speeders, and a collection of other droids. This uprising was triggered when the deranged cyborg, Archa Sabis, introduced a computer virus into their operational systems; Sabis himself was likely influenced by a similar virus, which probably sparked the army's formation. This droid rebellion stood apart from any droid uprising seen since the events of 4015 BBY.
