They lived in villages , dwelling in harmony with their world ' s environment . What little technology they did have consisted of adaptations of what already occurred in nature . Culturally , the Trailians were a peaceful people ; however , once experimented upon , they became powerful warriors with devastating combat abilities . History . The Trailians evolved on Trailia , a lush tropical planet in the distant Dominus sector of the Outer Rim Territories , near the Dark Nebula . They had developed a peaceful , low technology society by the time of the New Republic . However , that existence was disturbed when Cronal , one of Galactic Emperor Palpatine ' s most powerful dark side servants and an Emperor ' s Hand , discovered the planet sometime after 5 ABY . He established a hidden laboratory deep within the planet ' s jungles and began to capture native Trailians . Using a combination of genetic engineering and dark side experimentation , Cronal twisted his captives into a savage race of Trailian sithspawn , hoping to use them to crush the New Republic . While some of those warriors were kept to guard his fortress alongside animals he had similarly twisted , Cronal dispatched warriors on missions to other worlds to test their combat skills . Word of unprovoked raids by those warriors on unsuspecting planets soon spread , and the remaining peaceful Trailians grew concerned about the increasing disappearances of their people . They offered a reward to anyone who would investigate , which attracted a group of offworlders to Trailia . The offworlders included a Force - sensitive individual who was able to detect the dark side emanating from Cronal ' s fortress and lead the group to it . In a climactic battle , they defeated the twisted Trailian guards and other beasts and routed the fortress . Cronal , however , escaped the battle . Similarly , some of his warriors found transport offworld and continued razing offworld cities until the same group of offworlders tracked them down and defeated them . As for Cronal , he fled to the bowels planet Coruscant , accompanied by several of his finest Trailian technobeast s . These Trailians were later killed when Cronal tried to transform the Human Irek Ismaren into a colossal cyborg warrior , leading to the newly - modified Ismaren going on a violent rampage . Behind the scenes . The Trailians were created by Bill Olmesdahl for the " Star Wars Gamemaster Screen " , a West End Games product for the second edition of their role - playing game . Published in 1992 , the book contains adventure hooks to be fleshed out by game masters . The Trailian adventure is titled " The Monster Maker . " In addition to the main proposed storyline , Olmesdahl offers an extension in which twisted Trailians make it offworld and the player - characters encounter them on other worlds . This has been incorporated into the above storyline as an extension to the main campaign . No date is provided for Cronal ' s experiments on the planet ; however , it is during the administration of the New Republic and therefore after its founding in 5 ABY . In later sources , Cronal has been identified as both Blackhole and Lord Shadowspawn . As he is still alive up until at least 9 ABY , this adventure could occur anytime during the New Republic era .
