Star of the Tion The Star of the Tion was a modified YT - 1300 freighter assigned to members of the Alliance tasked with delivering updates for Alliance cell networks during the oppressive rule of the Galactic Empire . The ship was white with green striped markings . History . Upon entering the system of the industrial world of Lianna , the crew of " Star of the Tion " encountered a sizable Imperial fleet congesting the space lanes leading to the planet . There was no combat at the time for a war fleet of that size to be displaying such a presence , which meant that the Empire was looking for something . The Rebel crew were able to use their ship ' s modified sensors to detect a small vessel about the size of a two - person escape pod " flickering " in and out of view as it went . The sensors were good enough to help the crew ascertain that the vessel was actually a probe droid that the Empire had outfitted with a small cloaking device . This led to the discovery of the Empire ' s secret cloaking shield project called NOVA , and their regular mission being diverted to retrieve and disable the plans from the Santhe / Sienar Technologies Corporate Headquarters located on Lianna . Escape from Lianna . After disabling the NOVA project , the " Star of the Tion " was pursued by two " Lianna " - class picket corvettes — the " Reliant " and the " Audacious " — who attempted to cut off the Rebel ' s escape to hyperspace . Unlike most pursuits in space , where there is only emptiness between the pursuer and the pursued , the area surrounded Lianna was clogged with small freighters , pleasure yachts , cruise liners , bulk freight cruisers and many more kinds of ships . The " Audacious " tried to herd the Rebels toward the " Reliant " , and the picket ships nearly caught the Alliance craft between them . They were unsuccessful in trying to corral the " Star of the Tion " , however , and left it for the waiting " Victory II " - class Star Destroyer " Warlord " , an older class ship assigned to sector patrol . Though competently commanded , the " Warlord " had its best TIE squadron reassigned to a sector with more Rebel activity to be replaced with inexperienced pilots , thus allowing the " Star of the Tion " to maneuver and fight through the blockade to escape . After entering hyperspace , the Rebels checked the plans to see if they were still intact . However , the Liannan engineers were quite capable in programming copy - protection protocols into their work . Five hours after the plans were stolen from the computers , a virus hidden deep within the software was activated . The program code succeeded in wiping all data from the storage device it was downloaded onto , leaving no viable copy of the plans for the NOVA project to continue . Weapons Upgrade . Among the modifications later made to the ship were the replacement of the standard laser cannons with a light - duty turbolaser upgrade . This may have been a discreet contribution made by Lady Santhe ( who was secretly allied with the Rebels ) of Santhe / Sienar Technologies Corporation as reward to the crew of the " Star of the Tion " for sabotaging the NOVA project , a most difficult Imperial entanglement for her on Lianna . Behind the scenes . In the WizKids ' game , Star Wars Pocketmodels TCG : Base Set , the ship appears as a game piece called " Star of Tion " featuring turbolasers .
