Hafner Hafner was a male Duros scientist who worked for the biotech company Kelen Biolabs during the Galactic Civil War . Sometime shortly after the Battle of Yavin , he traveled as part of a collection crew for the Biolabs to the moon Fex in the Deep Core Sha Qarot system to survey and find possible valuable biological samples . Once on the moon , he and two other members of the team disembarked from their starship the " Harvester " and began investigating Fex ' s wildlife . However , the trio were soon ambushed by the previously undiscovered apex predators of the moon , the Fexian skullborer s , which quickly killed Hafner ' s two compatriots before Hafner could stun them . Calling the " Harvester " to pick them up , Hafner began to observe one of the skullborers after stunning it , recording valuable information with the holocam in his helmet . Before the " Harvester " could pick him up though , the Duros was attacked and killed by the skullborers , and his recordings were returned to Kellen Biolabs . The recordings were later viewed by the rebels Luke Skywalker and Nakari Kelen after they were sent on a follow up collection mission to the moon . Biography . The male Duros Hafner was a scientist who worked for biotechnology Kelen Biolabs , a company which conducted zoo logical research in search of medical applications . Shortly after the Battle of Yavin during the Galactic Civil War , Hafner was sent by the company as part of a collection crew to Fex , an unexplored moon in the Sha Qarot system of the Deep Core region of the galaxy . Fayet Kelen , the owner of Biolabs , believed Fex might be a rich source of wildlife to research due to the star system s unusual red star . Hafner and the rest of the team traveled on board the XS - 800 light freighter " Harvester " to the moon , and while there was sent down to the surface along with the Bith Priban and a human member of the crew in order to scout and collect developmental leads . While the trio were scouting , all three recorded video of the environment from their helmets ' holocam s , with Priban leading the group and giving commentary . As the scout s moved through the moon ' s crystalline forests , Priban was attack mid - sentence by a Fexian skullborer , a previously undiscovered apex predator of Fex which was invisible to the naked eye due to natural camouflage . The Bith called to Hafner and his other colleague for aid , but the pair could not understand what was happening as Priban collapsed to the ground . The human was next to be attacked , and demanded that Hafner fire stun blast at his and Priban ' s heads in the hopes of hitting the invisible creatures . The Duros complied , but too late , as his colleague had already fallen motionless . The shot did stun the creature and reveal its form , as the skullborer was unable to camouflage itself while unconscious . Hafner then contacted the " Harvester " and reported on the incident while approaching the unconscious predator to investigate . The Duros pulled the unconscious skullborer ' s trunk from the cavity it had created in the human ' s helmet , only to reveal that the predator had been feeding on its victim ' s brain . He put down his weapon and picked up the creature , examining it closely and commenting on its various features , documenting the first information about the species . As he did so another skullborer dropped onto Hafner , who grabbed his weapon and stunned himself and the creature in the hopes that the " Harvester " would arrive and save him while he was unconscious . The ship was not fast enough to save the Duros though as the stunned skullborers soon awoke , and when it arrived the Duros brain had been eaten in the same fashion as his colleagues . The remaining crew members collected the three corpses using the starship ' s cables and fled the moon . The " Harvester " later returned to Fex with a new crew equipped with harder helmets , but all bar one of them were killed by the skullborers when five escaped their confinement . A third mission to investigate the moon was made by the rebels Luke Skywalker and Nakari Kelen , the daughter of Fayet Kelen . The pair watched the holographic footage of Hafner and his colleague ' s deaths on Fex as a way of inform and prepare themselves for the moon ' s wildlife . On the moon they found the " Harvester " and killed the skullborers onboard , returning the ship and its sole surviving crew member to Kelen Biolabs . Personality and traits . Hafner had green skin and red eyes . When Priban was first attacked by the invisible skullborers he Duros appeared terrified and could not react in time to save his colleagues life . However , Hafner remained calm and collected while investigating the creature and his colleagues ' corpses . Luke Skywalker found this odd , believing it to be a trait shared by many scientists , disregarding their own safety and personal emotions when trying to accomplish a job or analyze a problem . Hafner even went so far as to put down his weapon despite the possibility of further attack in order to examine an unconscious skullborer , a fact that Nakari Kelen found illogical . Equipment . While on Fex , Hafner wore an armor suit with heavier protection around the head and shoulders . The suit included gloves and a helmet which was capable of recording video and communication with the " Harvester " . He also carried a blaster with a stun setting . Behind the scenes . Hafner first appeared as a hologram in " Heir to the Jedi " , a canon novel written by Kevin Hearne and published in 2015 .
