Eso Eso was a male Trandoshan captain of the Alliance to Restore the Republic who conducted combat activities out of a camp in the Val ' Arnos Jungle on Yavin 4 during the Galactic Civil War . Biography . Flanking the Empire . The male Trandoshan by the name of Eso was alive during time of the major galactic conflict known as the Galactic Civil War , during which the Alliance to Restore the Republic won a decisive victory against the Galactic Empire at the Battle of Yavin in 0 BBY . About 6 months later , the Rebel Alliance evacuated the moon , but Eso remained embroiled in combat against the Empire while stationed out of a camp in Yavin 4 ' s Val ' Arnos Jungle . By that time , Eso held the rank of captain in the Rebel Alliance and fought alongside several Rebel commandos , including a marine armor - clad Zabrak sergeant by the name of Yith Seenath . During his time at the camp , a recon team dispatched by Captain Eso found themselves pinned down by unexpected numbers of wetland assault stormtrooper s . Fortunately for the battle - hardened Trandoshan , an individual loyal to the Rebel cause arrived to Eso ' s camp and agreed to help him save his men . Eso uploaded the location of known Imperial forces to the Rebel ' s datapad , and recommended that a stealthy approach be utilized to quietly shoot the Imperials in the back of their skulls . While the operative did succeed in reaching the squad of Imperials , the Rebel was detected by one of the swamptroopers . After shouting that they had been flanked , the rest of the squad opened fire on the Rebel combatant , eliminating any chance of a quick and quiet solution . However , the surprised Imperial forces were no match for the Rebel ' s superior combat ability , and were eventually killed during the firefight . Although the recon team was rescued , Captain Eso derided the Rebel operative for what he perceived to have been a messy and reckless approach . Nonetheless , he ultimately commended the Rebel for completing the rescue operation successfully . Destroying the Triage Unit . Thanks to the efforts of the rescued recon team , a hidden triage camp was discovered out in the dense jungle of Yavin 4 . Eso remarked that because of Yavin 4 ' s isolated nature , the Empire did not have the time to take their stormtroopers to a fully operational medcenter . He remarked that out in the battlefield , soldiers would simply throw on bacta - soaked bandages and get back out into battle . To that end , Eso urged the Rebel operative to set out to the triage camp and kill the Empire ' s field medic . To Eso , medics were not to be seen as non - combat units , but rather active participants of war . The Rebel operative who had helped rescue the recon team was not soft to the realities of war , and agreed to carry out the captain ' s wishes . The Imperial triage camp was staffed by a single Imperial field medic and equipped with functioning bacta tanks . When the medic sighted the approaching Rebel operative , he shouted for his friends to save him . Out of the brush , a couple wetland assault stormtroopers emerged to open fire on the Rebel . However , their attempt to save the life of their field medic was in vain . Once again , the Rebel operative proved to be more formidable in combat , and all who defended the triage camp were killed . With the triage unit gone , Eso remarked that it would be easier to hunt down additional troopers , and that the Empire might now be unable to come at them with full force . An Infected Wound . Captain Eso was faced with the difficult responsibility of dealing with a young , shell - shocked Rebel soldier . Eso believed that the young kid had seen too much fighting and was about to snap . Eso likened this soldier to a rotting wound which endangered his entire body of men . He feared that if the disturbed soldier were to lash out at an inopportune time , it could result in his entire battalion being wiped out by Imperial forces . Eso recognized the sensitive nature of the situation , and asked the Rebel operative to help resolve it . The Rebel operative , who had already eliminated one the Empire ' s medics , was not the squeamish type . Eso instructed his operative to approach the young soldier , tell him , " Hey , look over there , " and shoot him with his back turned . Removing the Wound . The Rebel operative set out into the wilderness to locate the shell - shocked soldier , who was a trooper within the Alliance Military . The operative eventually sighted the young man in the thick jungle calling out for his mother to bring him home . Although Eso had instructed the operative to use subtlety in executing the battle - wearied soldier , the maddened Rebel sighted Captain Eso ' s operative brandishing a blaster , and asked what it was going to be used for . Before he could say anything more , the Rebel operative fulfilled Captain Eso ' s orders , and shot and killed the Rebel . When the operative returned to Eso to report the news , the Captain simply remarked that they both had blood on their hands , but that the job needed to be done in order to save the rest . Preparing for Evacuation . Unfortunately for Captain Eso , summarily executing the young soldier proved to be in vain . Prior to being killed , his cries out to his mother were recorded by Imperial probe droids , allowing them to pin down their camp ' s location . With their whereabouts compromised , Captain Eso had no choice but to evacuate his fellow commandos . To help buy them some time , Eso ordered the Rebel operative to take out preliminary Imperial scouts seeking to confirm the camp ' s location . In order the save the lives of Captain Eso ' s battalion , the Rebel agreed to defeat as many incoming Imperial stormtroopers as possible . When the Imperial scout force sighted the Rebel operative , one of them remarked that they were in the right place , and to start by killing lone the Rebel . Despite facing overwhelming numbers in the face of the preliminary scout force , the Rebel had managed to kill a swath of stormtroopers . Facing the Empire . Thanks to the Rebel operative ' s success in eliminating the preliminary scout force , Captain Eso managed to pull a full evacuation of his soldiers . However , the Empire still knew of their location , and was planning an offensive . Nonetheless , he curtly commended the Rebel operative who had aided him so loyally , and gave one final order to leave the camp for good . Even though Captain Eso believed that a few hundred Imperial troops were incoming , he was determined to stay behind to take care of them himself . Personality and traits . Eso had green scaly skin , and gold colored eyes . Equipment . During his time in the Val ' Arnos Jungle , he wore a gray formfitting undershirt beneath a brown camouflage spec - ops duster . He also wore brown paramilitary camo pants and a dark colored helmet which resembled those commonly worn by Rebel forces during the Battle of Endor , including Luke Skywalker and Leia Organa . Behind the scenes . Eso was a in the 2003 video game " Star Wars Galaxies : An Empire Divided " , a massively multiplayer online role - playing game developed by Sony Online Entertainment and published by LucasArts , prior to its closure on December 15 , 2011 .
