Tren The Tren were a species of sentient humanoids with tough , hairless , blue - purple skin and simple facial features . Members of the species sought order in their society , a pursuit that sometimes impeded their judgment of right and wrong . The Tren colonized three worlds , including Nopsin . During the Galactic Civil War , the Tren were initially divided over whether to support the Galactic Empire or the Alliance to Restore the Republic . As the Tren colonies swore their allegiance to the Empire one after another , a resistance movement sprung up to oppose the New Order . When Nopsin voted to join the Empire , the species had become completely integrated into the Empire . Nevertheless , the resistance continued , at least at the individual level . One such Rebel sympathizer was the Tren Opit - Wenbruh , who finished his commission in the military and joined the Rebel Alliance . He served as a member of Scandium Team and Brace Team as a heavy weapons specialist . Biology and appearance . The Tren were sentient humanoids with stocky builds and thick , bluish - purple skin that was resistant to injury and damage . Each member of the species was completely hairless and had five - fingered hands . The species was divided into males and females . The Tren head was largely Human - like , with two eyes , a nose , a mouth , and two ears positioned like those of a Human . Nevertheless , their large jaw and angled forehead , coupled with their pupil - less eyes , made Tren seem to have " simple " faces in the eyes of other species . Society and culture . A strong desire for order permeated Tren society . That impulse was so compelling that it sometimes superseded the species ' sense of morality . The Tren had access to space - travel technology , and they founded three colonies . At least one of those , the planet Nopsin , had a military during the Galactic Civil War . Soldiers on Nopsin were forbidden to pursue other occupations until they had completed their tour of duty . History . The Tren colonized three different planets , the last of which was Nopsin , a world in the Mid Rim that they reached sometime before the outbreak of the Galactic Civil War . During that galaxy - spanning conflict , the Tren found themselves unsure whether to declare their loyalties to the Galactic Empire or the Alliance to Restore the Republic . Resistance movements sprung up to oppose the New Order and agitate for the Tren to support the Alliance , but a strong desire for order compelled other Tren to back Emperor Palpatine ' s new regime . Eventually , two of the three colonies officially threw their support behind the Empire , criminalizing the pro - Alliance fighters , suppressing the remaining fighters , and wiping out much of their support . Only Nopsin remained undecided on the issue . Nopsin eventually held a vote over the planet ' s allegiance , a vote that the pro - Imperial Tren won in a landslide . The remaining resistance fighters realized that theirs was a lost cause and gave up trying to convince their fellow Tren to join the Rebellion . With that , the Tren colonies became voluntary member governments of the Galactic Empire . Tren in the galaxy . As Nopsin threw its support behind the Empire , a young soldier in its military named Opit - Wenbruh found his loyalties divided . As one of the few Tren who valued morality over orderliness , he wanted to finish his tour of duty . However , the many actions of the Empire that he felt were immoral made him sympathize with the Tren resistance and the Rebel Alliance . Opit - Wenbruh waited for his term of service to end and then began a campaign against the Empire in retaliation for the evils he felt that it had perpetrated . Opit - Wenbruh eventually joined the Rebel Alliance as a member of the Scandium Team , one of the Rebellion ' s earliest Special Operations units . The Tren used his military experience by filling the role of a heavy weapons specialist . With the dissolution of Scandium after it suffered heavy losses in various engagements , Opit - Wenbruh served as a weapons technician and designer . He later joined Brace Team , an Alliance group that specialized in using heavy weapons to create a barrier between Alliance and Imperial forces . Behind the scenes . The Tren were created by authors C . Robert Carey and Trevor J . Wilson for the article " Cracken ' s Rebel Operatives , " published in the " Star Wars Adventure Journal " 11 in November 1996 . The Tren character they introduced , Opit - Wenbruh , was illustrated by Kathy Burdette . Years later , in 2011 , an update to " " included an entry for the Opitha Tren system . Comments made by Jason Fry , one of the authors of " The Essential Atlas " , indicate that several new star systems have been introduced as part of the " Atlas " project to represent the homes of species , based on context implied by their names . Opitha Tren thus may be intended to represent the home star system of the Tren species .
