Raioballo sector / Legends Raioballo sector was a sector in the Outer Rim Territories encompassing thousands of inhabited worlds . These included the stormy Tertiary Kesmere , tranquil Dantooine , oceanic Shusugaunt , the industrial world Sinsang , and Anx Space , containing the Anx homeworld of Gravlex Med and a number of their colony worlds . The hyperspace route Myto ' s Arrow ran through the sector , connecting Dantooine to the Obtrexta sector . Numerous battles were fought in Raioballo sector during the major galactic wars . Fighting occurred at Dantooine during the Clone Wars , the Galactic Civil War , and the Yuuzhan Vong War . The last major fleet battle between the New Republic and the Imperial Remnant occurred within Anx Space . History . For many years , Raioballo sector was represented in the Galactic Senate by Horox Ryyder , an Anx renowned for his level - headed impartiality . On his retirement , Ryyder was awarded the Royal Chalcedony Shield , typically only given to Alderaanians . Ryyder was replaced as Raioballo sector senator by fellow Anx Zo Howler and his aide Fo Kuna . Early in the Galactic Civil War , the sector was home to an Alliance to Restore the Republic base on Dantooine . However , the base was abandoned before the Battle of Yavin . Shortly after this , Imperial defector Tycho Celchu tried to hide on the planet , but his defection was detected and an Imperial strike force attacked the planet . Celchu was rescued by the intervention of Luke Skywalker and a rebel strike team . Later , when the New Republic came to power , they established a small colony on Dantooine for the refugees from Eol Sha . This was discovered by the renegade Imperial Admiral Daala who massacred the colonists as a political strike against the Republic in 11 ABY . During the period of the New Republic , the sector contained a large shipyard at Gravlex Med , used for scrapping mothballed capital ships . The Imperial Remnant paid slicers to get the " Imperial II " - class Star Destroyer " Chimaera " transferred there , and then proceeded to steal the ship which had once been Grand Admiral Thrawn ' s flagship . Years later , another key engagement between the New Republic and the Imperial Remnant occurred in the sector . In 17 ABY , the navies engaged over Anx Minor , with both sides led by their top commanders ; Admiral Ackbar and Fleet Admiral Gilad Pellaeon , respectively . The battle resulted in victory for the Republic , and was the last large scale fleet engagement fought between the two powers . During the Yuuzhan Vong War , Raioballo sector lay along the initial invasion path of the Yuuzhan Vong . As such , one of the early engagements of the war took place on Dantooine , in 25 ABY . New Republic refugees from the further rimward worlds of Dubrillion and Destrillion were being processed on the planet , when the Yuuzhan Vong launched an attack . The invaders killed as many as 45 % of the refugees and many soldiers before Admiral Traest Kre ' fey arrived , facilitating escape for the remaining Republic forces . Behind the scenes .
