The Del Zennis System was a star system that was used as a research testing ground for the Galactic Empire's Imperial Interdictor during the Rebel Insurgency. The Imperial Interdictor was a prototype warship equipped with four gravity well projectors that were capable of pulling ships out of hyperspace. Under the command of Admiral Brom Titus, the Interdictor succeeded in destroying one rebel patrol and captured a CR90 Corvette called the Liberator, the flagship of the Phoenix Rebel Cell. Among their captives were Commander Jun Sato and Jedi Padawan Ezra Bridger. During a rescue mission mounted by Kanan Jarrus, Rex, and "Chopper", the Imperial Interdictor and its escort light cruisers were destroyed, leaving the surrounding space strewn with wrecked debris and starship parts. Admiral Titus survived the devastation in an escape pod and was retrieved by Agent Kallus.
