Barosa Warren Barosa Warren was a lawman , an expert survivalist , and chancellor of the Galactic Outdoor Survival School , with a personal vendetta against those former students of his who had joined the Rebel Alliance . A long - lived Morellian , he was believed to be the last surviving member of his species . Biography . Barosa Warren was born on Morellia , a member of a long - lived Near - Human species known as Morellian s . Probably born in 167 BBY , he was still active in 2 ABY . During his youth , Warren served in the Morellian Enforcers , a police - like corps using limited technology such as the Morellian Weapons Conglomerate . 48 - caliber Enforcer pistol . He also used the traditional Morellian Enforcer uniform , including leather boots , blackstrap gloves and a long oilcoat made of leather . Afterward , Warren joined the Galactic Republic as a scout . He was known for reclaiming dangerous worlds such as Buamlon Central , Frewwil , Theal , and Dra III — where he was attacked and injured by a nashtah . This attack caused permanent scar on his right arm . During this time , he became a well - known galaxy - wide authority in hostile terrain survival . By 57 BBY , Warren was still quite young for a Morellian . However , he announced his retirement as a scout , wanting to fulfill his greatest dream . He talked with some friends trying to get financial backing , and lost their friendship while doing so , but he bought a planet in the Ollonir Boundaries . The planet , OM813 ( renamed Thrantin ) was then planetscaped to create a training camp for his survival school . Warren thus created Zero - G areas , an Ammonia Ocean and the Heavy Grav Mountainous Zones . While Warren admitted he should take students to different worlds to teach them , he also believed in having a " controlled environment " to ensure that none of his students could cheat . In some forty years , Warren had created the Galactic Outdoor Survival School , an unofficial organization training survivalists to thrive in environments hostile to their own species . Warren himself became the chancellor , dean and master instructor of the School , though he also employed a specialized staff . Many of the staff were extremely loyal to Warren personally , especially Stren Grier and Casti Tholon , who was also Warren ' s assistant , favorite , and personal friend . He also obtained several dozens of ships he used at school , including at least seven modified " Mu " - class shuttles and his personal vehicle , the " Cannibal " . The Galactic Outdoor Survival School , or G . O . S . S . , had since become a leading center . Many of the alumni became corporate , independent , or politically - aligned Imperial or Rebel scouts ; others had become instructors at the GOSS or at their own centers . Warren also had multiple children , all of them half - Morellian , half - Human ( which led to belief that Warren was the last Morellian ) . His known children included Alton Lochner , Danlea Lochner ( both of whom changed their surname due to not being on good terms with their father ) , Roland Warren and Tole Warren . Around 17 BBY , the Summit Class became the greatest class ever in the GOSS , managing to set a record in the final trek used as an exam . Warren respected the results and the performance of the Summits . Seven years later , the Twilight Class broke the Summits ' record in more than one day . Warren took the mine survivalist of the Twilights , Larq Thur , and offered him a job as instructor at GOSS ; another of the Twilights , Kiras Torla , was a close friend of Warren and his staff when she finished the studies . However , eleven of the twelve Twilights joined the Rebel Alliance after that . Warren , who held nothing but contempt for the Rebellion , considered them since his personal enemies . Some of the students believed that Warren had even sent mercenaries and bounty hunters after them . Torla , formerly a friend for Warren , was so scared of him that she disappeared from known space . Twilight veterans and Rebel officers Sisquoc , Ma ' w ' shiye and Derembus Sitnalta wrote extensive reports on Warren to warn other Rebels of the danger posed by him . Behind the scenes . The guide " Alliance Intelligence Reports " provides some trouble with Barosa Warren ' s age . He is said to be in his 110s when he began with the GOSS project , and four decades passed until he opened it ( in his 150s ) . He was in his 160s around 2 ABY ( " current age " during the reports ' writing ) . Thus , the GOSS had been open for one decade , since 8 BBY . However , the Twilight Class graduated at GOSS 12 years before the " current events " , thus 10 BBY , and they broke a 7 - year - old record by the Summit Class — which leads the GOSS being open at least around 17 BBY . The only birthdate that fits all the above facts is 167 BBY . It allows him to be exactly 110 when he begins work on the GOSS in 57 BBY , technically " in his 110s . " " Four decades later , " he would be 150 in 17 BBY , with time for Summit class to set their record later that year . Twilight class breaks it 7 years later in 10 BBY , twelve years prior to " present events " in 2 ABY when Warren would be 169 , still " in his 160s . "
