A single group of Diviner pods is launched from the Cerebus. Diviner represented a team of viper probe droids that served the Galactic Empire in 3 ABY.
Diviner had its base on the Cerebus. Following the Imperial forces' triumph over the Rebel Alliance during the Battle of Hoth in 3 ABY, Admiral Holtz received orders to eliminate the Defiance Task Force, the Rebel fleet responsible for protecting the Hoth survivors. Holtz intended to accomplish this by spreading viper probe droids throughout the galaxy to locate the aforementioned task force. Diviner was among the probe droid teams given this assignment.
In 3 ABY, the Corrupter Task Force deployed Diviner; this occurred when the fleet came under attack from two A-wings launched from the Mon Calamari Star Cruiser named Defiance. Ace Azzameen, one of the A-wing pilots, was responsible for the complete destruction of Diviner.
