Mission to Graleca The mission to Graleca took place during the Galactic Civil War partially aboard the " Devastator " and in the Jerrilek kan city of Graleca , as a group of Rebel operatives assisted Chel Dorat in defecting from the Galactic Empire to the Rebel Alliance . Aboard the " Devastator " . The Imperial Star Destroyer disabled a Rebel starship in a space battle , and a boarding team led by a young officer boarded it and took the surviving Rebels captive . The Rebels were imprisoned in the ship ' s detention area and subjected to an unusually mild form of interrogation by a Naval Intelligence interrogator . After the interrogation , the Rebels were given some sealed ration packets . In one of them , they found a concealed earphone with a recorded message on it . The message informed them that at 1600 hours precisely , the ship would suffer a reactor failure , causing the electronic locks in the detention area to deactivate , and leaving the ship without power for nine minutes . At 1600 hours , the " Devastator " did suffer a power failure . The Rebels took advantage of the situation and , aided by the Umarian brothers and possible some of the other prisoners , they made their way past the detention area guards , the naval crew and two R3 droids into the ship ' s docking bay where they found a ship . After manually manipulating the airlock into opening , the Rebels blasted off , escaping the " Devastator " . Upon escaping , the Rebels found an extra entry in the ship ' s log , which was a recording of a mysterious Imperial officer wearing a blast helmet . The officer informed them that the Imperial Security Bureau has sent a team to Jerrilek to arrest the Imperial admiral Chel Dorat for treason . The officer asked the Rebels to go to Jerrilek and warn the admiral . Graleca . The Rebels arrived at the city of Graleca on the planet Jerrilek . In the local starport they noticed an Imperial " Guardian " - class Imperial Customs cruiser , but were unable to retrieve any information on it from the starport securities . The Rebels then proceeded to the Dorat villa in the southeastern part of the city , where they encountered the servant droid D3S and Dorat ' s daughter Preela Dorat , who informed them that he had left with a group of historians who wanted to interview him about his time in the Old Republic Navy . The Rebels quickly figured the so - called historians were probably ISB agents , and through a pair of macrobinoculars , they could see the admiral and his abductors aboard a seaskimmer heading across the bay towards the starport . Borrowing Preela ' s seaskimmer , the Rebels pursued the ISB operatives . Being inexperienced at seaskimmer piloting , the ISB operatives initially traveled at half speed , allowing the Rebels to quickly catch up with them . As soon they realized they were being followed , the ISB operatives opened fire at the Rebels , and a dramatic seaskimmer chase ensued endangering several fishing boats and jetboarders . Having caught up with the ISB operatives , the Rebels easily defeated them , but as they explained to the admiral that they were there to rescue him and bring him to safety , Preela who was with the Rebels on her skimmer , revealed that she was with the Galactic Empire and , pulling a blaster , informed the Rebels that she had no intention of letting her father escape . The Rebels , however , managed to either defeat her or escape , and made it to the local starport where they blasted off in the ship they had stolen aboard the " Devastator " . Space above Jerrilek . The " Guardian " - class ship , which was in reality a " Warden " - class cruiser , that the Rebels had spotted in the starport belonged to the ISB , and having found learned about the Rebels ' escape , the " Guardian " - class ship ' s crew set off to destroy the Rebels and the defector . Furthermore , the ISB operatives ordered an IVP - 1 Inter - System Patrol Craft , which was orbiting the planet , to assist in capturing the Rebels . However , the Rebels managed to fight off their pursuers , and with the aid of a star destroyer that suddenly exited from hyperspace and fired at the Imperial pursuers only to vanish into hyperspace again , the Rebels and their new colleague made it into safety .
