Vorknkx The Vorknkx was a CR90 corvette in the service of the Galactic Empire during the Galactic Civil War . History . The " Vorknkx " was the prototype vessel used in an Imperial scientific project of the same name , which had the goal of developing a cloaking device for a small - sized craft . It would become the mechanism by which Imperial traitor Grand Admiral Demetrius Zaarin was finally defeated by his archenemy and Imperial successor , Grand Admiral Thrawn . Though Zaarin and Thrawn had skirmished for months and Zaarin ' s forces had slowly been whittled down by the larger loyalist force under Thrawn ' s command , the former Admiral was irritatingly good at keeping his flagship , " Imperial " - class Star Destroyer " Glory " , and therefore himself , out of harm ' s way . Thrawn used his assignment to defend the " Vorknkx " project from Zaarin as a chance to change this pattern and end Zaarin ' s rebellion against the Emperor once and for all . Thrawn knew that Zaarin ' s core weakness was his desire to possess new military technology for himself . He also had received an exclusive report from the scientists in charge of the project which suggested that the experimental cloaking device aboard the " Vorknkx " could produce a catastrophic power overload if used in conjunction with the craft ' s hyperdrive . Both of these weaknesses became a critical part of Thrawn ' s plan to ensnare his enemy . Zaarin ' s forces had attacked the station where the Vorknkx Project was being conducted , but had been repulsed by Thrawn ' s fighter patrols , led by Maarek Stele . When the project was moved to a hollowed - out asteroid some time later , Thrawn allowed the " Vorknkx " s new location to be discovered by Zaarin . When Zaarin inevitably threw all of his remaining transports at seizing the project , Stele easily destroyed them . A double agent planted by Zaarin attempted to steal a shuttle and flee in the chaos of the battle , but was also shot down by Stele . With his transports gone and unaware that his spy had been eliminated , Zaarin joined the battle himself aboard " Glory " . Using the remote device which the spy had planted on the " Vorknkx " , Zaarin was able to guide the ship into his own hangar bay . He then quickly fled the scene , thinking he had triumphed . In actuality , Thrawn had already learned that the spy had compromised the " Vorknkx " and had ordered a homing beacon to be placed aboard the ship . When the " Glory " disappeared into hyperspace , Thrawn ' s entire task force followed . Thinking that he had already outsmarted Thrawn , the overconfident Zaarin was caught off guard by the appearance of so many Imperial ships . Thrawn ' s forces quickly cornered ' Glory ' , which was overwhelmed and doomed . With his flagship crumbling around him , Zaarin fled in the " Vorknkx " , assuming that , having cloaked immediately , Thrawn ' s forces would be too caught up in the destruction of the " Glory " to notice his escape . Gloating about having given Thrawn the slip once more , Zaarin activated the " Vorknkx " hyperdrive . The resulting explosion completely tore the ship apart , killing Zaarin instantly . Thrawn , grinning from the bridge of his Star Destroyer , had finally won the day . Emperor Palpatine ordered the project mothballed soon afterwards , as the sole intention of the research had been to achieve the final defeat of Zaarin and that had been accomplished . It is not known if the technology used in the Vorknkx project survived in another form after the " Vorknkx " was destroyed .
