Zaarin led his Imperial - class Star Destroy " Glory " to destroy the station . Loyalist forces managed to retrieve the remaining TIE Defender prototypes , Proto 11 and 12 onto a freighter " Mharsup " and the scientist onto a shuttle " G ' nabgib " . The shuttle would rendezvous with 3 modified corvette " Hashim " to place a TIE Defender in each corvette , with Maarek Stele ' s being in Hashim 3 . After fending off Rebel forces trying to capture the prototypes , Hashim arrived to find itself in a trap laid by Rneekii Pirates . By the time Stele was launched to fight of the pirates , transport Ibutho 1 had already boarded the shuttle and kidnapped the scientist along with the data . Not long afterwards Proto 11 was stolen by a Nami team while Stele was engaging Rebel raiders . The Rneekii decided to ransom the scientist to highest bidder , which was the Empire . Unfortunately , the pirates underestimated the Empire and after negotiating the ransom near the planet Kiilimaar , the Empire used Maarek Stele to outwit and trap the pirates with a Interdictor " Red Claw " . After the scientist was on another shuttle , the code " Full Speed to Kiilimaar " was sounded and Stele engaged the pirates and the " Red Claw " arrived preventing their escape , when another Nami strike team disabled the shuttle and damaged the " Red Claw " disabling its hyperdrive and Gravity Well generators stranding both ships .
