This gives C'baoth a taste for power, though, and soon he's mind-controlling entire Star Destroyer crews to his will and rewriting brains from scratch. However, with Dark Jedi insight, Thrawn could park a cloaked ship inside a planetary shield and make it look like his Star Destroyer was able to fire right through the shield, causing entire planets to surrender to the Empire. In Zahn's books, cloaking was never used because it blinded the cloaked ship to anything going on outside.
For instance, Thrawn put cloaking devices on smaller ships and used C'baoth to coordinate them. He is recruited by Imperial Grand Admiral Thrawn who, himself protected by Force-canceling alien creatures called ysilamiri, uses C'baoth as part of psychological warfare against the New Republic. At first, C'baoth is thought to be simply a Dark Jedi that the Emperor was using to guard a mountain storehouse of deadly Imperial gadgets.
