Prelude . After stealing one of the Empire ' s TIE Defender prototypes from the Imperials and , with the help of Rogue Grand Admiral Zaarin , abduct the Chief Scientist of the TIE Defender project . The Nami leader and Crime lord Ali Tarrak , had managed to gain the ability to manufacture and produce her own TIE Defenders . After showing a demonstration on an Imperial Cargo area , with a Rebel cruiser as a observer , it became apparent that she intended to proliferate from this by selling TIE Defenders to various parties , the Rebel Alliance in particular . Admiral Thrawn was tasked to counter this threat and had begun his own starfighter ever since the Rneekii had originally kidnapped the Chief Scientist . Now with the discovery of a Nami Strike cruiser planning to rendezvous with the Rebels to arrange purchase of 8 TIE Defenders . Thrawn decided to let the Empire ' s best Imperial Ace Maarek Stele test his new project , the Missile Boat on its first official combat mission . The Battle . First stage . Two Missile boats escorted by Assault Gunboats arrived at the rendezvous site and started engaging the Nami T - wings , Gorgg Squadron . The Strike cruiser " Nuance " launched more T - wings one squadron at a time , while launching 3 stormtrooper transports " Miner " to deploy mines around the ship . As the T - wings were taking heavy losses a Rebel Carrack - class light cruiser Prism arrived . Stele managed to finish of the remaining T - wings and destroyed all 3 transports deploying mines . He then helped the Assault Gunboats disable the " Nuance " . Not long afterwards the Imperial - class Star Destroyer Grey Wolf arrived to deliver a Assault transport to board and capture the " Nuance " , recovering 8 TIE Defenders , and with the help of the Gunboats destroyed the " Prism " before it could retreat into Hyperspace . Stele ' s sensors picked up a probe called Yey nearby and destroyed it . Thrawn would later learn of Tarrak ' s manufacturing factory where she was building more TIE Defenders . But first he decided to make a stand , knowing that the Rebels weren ' t going to give up the TIE Defenders without a fight . Second stage . As predicted , the Alliance sent 3 Carrack cruisers " Kingdom " to attack the " Grey Wolf " . Stele launched from the Hanger in a Missile Boat to engage the X - wings that were attacking the " Grey Wolf " , followed by engaging the A - wings as they were finishing of the TIE Fighters , Stele then had to fend of two Y - wings Squadrons that were also making torpedo runs against the " Grey Wolf " . The Carrack cruisers finally launched Z - 95 Headhunters , which were also dealt with by Maarek Stele . He then began launching Space bombs at the Cruisers . During the run a Escort Shuttle " Black Box " launched from one of the cruisers , carrying Rebel Commanders , Stele inspected and then destroyed the Shuttle before it could escape .
