Ralroost The Ralroost was a Bothan Assault Cruiser commissioned at the end of the Galactic Civil War for the defense of Bothawui . History . The Bothans commenced the manufacture of Bothan Assault Cruiser s in the aftermath of the Bastion Accords , a peace treaty signed in 19 ABY which ended the long - running Galactic Civil War between the New Republic and the Galactic Empire . Although the construction of the Bothan Assault Cruisers in peacetime was a point of controversy , the warships made their way into the New Republic Defense Force . " Ralroost " was assigned to the command of Bothan Admiral Traest Kre ' fey of the New Republic First Fleet , who hand - picked his crew , the majority of whom were members of his own species . By 25 ABY , Kre ' fey ' s command was stationed in the Outer Rim Territories . During the Yuuzhan Vong War it was Admiral Traest Kre ' fey ' s personal flagship . The vessel carried Rogue Squadron during the initial weeks of the Yuuzhan Vong War , where they scoured the Outer Rim hunting for the Yuuzhan Vong . Its communications officer was Lieutenant Arr ' yka and its shield officer was Commander Grai ' tvo . The " Ralroost " first engaged substantial Yuuzhan Vong forces in the Battle of Ithor , where the planet was destroyed in spite of the fleet ' s best efforts . The ship also participated in the Battle of Coruscant , as the flagship of Fleet Group One . After the fleets scattered , the " Ralroost " went to Kashyyyk , where it and the ships that accompanied it staged raids from Duro to Ylesia to weaken the Yuuzhan Vong and train New Republic forces . After three months of conducting such raids , the " Ralroost " headed to Treskov 115 - W , a main - sequence star in the Deep Core , to prepare for an ambush of the Yuuzhan Vong fleet . For several weeks they trained and built up their defenses in the system , until they were attacked by an enormous Yuuzhan Vong force . The ambush was successful , destroying nearly a third of the Yuuzhan Vong fleet deployed , and the " Ralroost " went back to Kashyyyk . The path to Coruscant . The " Ralroost " remained on station over Contruum Six with the rest of the Galactic Alliance Defense Fleet . The war room of Kre ' fey ' s flagship was once again a meeting point for the military commanders who would be coordinating the strike on Coruscant . Several briefings were held before a final discussion was held 72 hours before the planned assault , at which Sovv ; Brand ; Bel Iblis ; Antilles ; Farlander ; Pellaeon and other military figures were present . Chief of State Omas and several of his advisers communicated via hologram . Once several Jedi Masters , including the Skywalkers , Kenth Hamner , Cilghal and Madurrin arrived , the meeting commenced . While Kre ' fey , Sovv and other military leaders were eager to press the attack on Coruscant , the Jedi urged caution , believing that the presence of Zonama Sekot in the Coruscant system along with the heretical uprising playing out on the capital ' s surface could bring about the defeat of Shimrra without the need for a fullscale battle . The military approach was prioritized , with the Jedi agreeing to use Zonama Sekot as a diversion for Warmaster Nas Choka ' s fleet . Elements of the Defense Fleet began moving out . For the time being , the " Ralroost " remained on station over Contruum 6 . Generals Antilles , Farlander , Bel - Iblis and Celchu was dispatched to recapture Corulag , which would allow the Defense Fleet a platform from which the assault on Coruscant could be launched . Kre ' fey waited on Antilles ' signal that Corulag was secure before moving " Ralroost " and elements of the First Fleet to the system . Contacting Antilles , Kre ' fey informed the Human general that he had one hour to secure Corulag , as he feared that Nas Choka might strike at the Contruum staging point . To prevent the plan from falling apart , Kre ' fey moved elements of Third and Fourth Fleets toward the Coruscant on different approaches , while ordering Antilles and his fellow generals to travel to Muscave , one of the outer worlds of the Coruscant system . In the following hours , the massed Contruum fleet separated as Kre ' fey ' s orders were carried out . While Antilles formed a line at Muscave , Pellaeon and the Fourth Fleet led the attack on the Yuuzhan Vong defense fleet arrayed over Coruscant . Return to Coruscant . " Ralroost " , grouped with forty other warships , emerged in the Coruscant system in between Muscave and Coruscant . The bulk of Nas Choka ' s armada was arrayed at Muscave combatting the forces of Antilles and Farlander , while simultaneously launching attacks on Zonama Sekot . On " Ralroost " < nowiki > ' < / nowiki > s arrival , Kre ' fey formed up his battle group and advanced rapidly on Coruscant to reinforce the Third and Fourth Fleets . Seated in his command chair on the bridge of the Bothan Assault Cruiser , Kre ' fey reflected on the battle , which was fiercely fought both at Muscave and Coruscant . Despite the reported death of Supreme Overlord Shimrra , the fighting showed no signs of abating . While Kre ' fey was pondering whether to retreat the Galactic Alliance Defense Fleet or press the attack despite the losses he would incur , the captain of " Ralroost " reported that Nas Choka ' s personal battle group had entered hyperspace and were expected to emerge imminently over Coruscant . " Ralroost " remained in the thick of battle ; once Nas Choka ' s flotilla arrived , however , the situation became more complicated . Supreme Overlord Shimrra ' s personal warship entered orbit and began moving toward Choka ' s battle group . As it did so , " Ralroost " suddenly became the target of Choka ' s entire flotilla . All of the warmaster ' s warships converged on the Bothan Assault Cruiser and subjected it to a punishing assault . " Ralroost " sustained significant damage , losing much maneuverability . When Shimrra ' s warship suddenly detonated in a fiery explosion , however , the Yuuzhan Vong surrender soon followed . The assault on " Ralroost " ceased — the Bothan Assault Cruiser had fought on the frontlines of the Yuuzhan Vong War since its commencement , and had survived the four years of conflict . Commanders and crew . " Ralroost " operated as the flagship of Admiral Traest Kre ' fey , a Bothan who had entered one of his species ' less prestigious military academies and received a more open - minded education in consequence . Kre ' fey ' s rise through the ranks of the New Republic military was rapid , in part due to the resignation of several senior Bothan military figures following the political debacle that was the Caamas Document Crisis .
