Sibwarra Sibwarra , renamed from Shriwirr , was a heavily customized Ssi - ruu vi " Shree " - class battle cruiser , and was the flagship of the attack fleet on the remote Imperial world Bakura shortly after the Battle of Endor . After it was captured by the Rebel Alliance , it was renamed in honor of Dev Sibwarra . Characteristics . The Ssi - ruuk were a saurian race from the very far reaches of the galaxy . The " Shriwirr " was a formidable ship , about 900 meters long and had the Ssi - ruuvi equivalent of 24 heavy turbolasers , 24 ion cannons , 12 concussion - missile launchers , 12 tractor beam projectors . She also carried 500 " Swarm " - class battle droids which were the Ssi - ruuvi equivalent of starfighters . Since Ssi - ruuk place a very high priority on capturing enemy ships , they often used the " Shriwirr " ' s tractor beam projectors and ion cannons to capture enemy ships which they dragged into huge landing bays . They then captured the crew of the ships and used a process called entechment to draw the life forces out of their captives and then transfer them into their droids , ships and computers . The " Shriwirr " had one large entechment lab onboard where many captives were turned into Ssi - ruu slaves . Thirty more of these labs were under construction prior to their defeat . The " Shriwirr " had five meter tall ceilings since the Ssi - ruuk were very tall . There were also several tunnels and passage ways for the P ' w ' eck s , a species conquered by the Ssi - ruuk , to get around the ship and do their duties . The Ssi - ruuk used the P ' w ' ecks as slaves . Since the P ' w ' ecks could not be trusted , the " Shriwirr " had stun traps to ensure that the P ' w ' ecks followed their orders and keep out of the ship ' s sensitive areas . These stun traps could stun a P ' w ' eck and were lethal to Humans . Conductive nets were also used to stop energy surges and to maintain a stabilized gravity since the Ssi - ruuk were not advanced enough to install artificial systems onboard their starships . " Shriwirr " was the Ssi - ruuvi word for " ripe with eggs . " History . During the Invasion of Bakura , Luke Skywalker was captured , but he broke free of the entechment lab and disabled the engineering control station . Although the Jedi Knight had been weakened and infected with a parasite , the Ssi - ruuk abandoned the " Shriwirr " rather than facing him in combat . The ship was captured by the New Republic forces , who then outfitted it and made it part of their own fleet . They renamed it " Sibwarra " after Dev Sibwarra , who had saved Skywalker . Some technicians called it " Flutie " , a derogatory name given to the Ssi - ruu k because of the way they communicated . But it was not funny to the men and women who had fought the alien invaders . After the Battle of Bakura , the " Sibwarra " led a New Republic fleet into Ssi - ruuvi space to deal with the alien menace . Some of the crew onboard the " Sibwarra " were killed during the journey by Ssi - ruuvi security devices still onboard the ship . When the New Republic task force reached Ssi - ruuk space , they discovered that the Ssi - ruuvi Imperium had been attacked by an unknown species . Seeing a weakened foe , the New Republic task force retreated back to Bakura .
