Tarc The Tarc were a sentient crustacean species , indigenous to the planet Hjaff . Standing at around two meters tall with four arms and a chitinous exoskeleton , they appeared intimidating to most humanoids , a reputation furthered by their ruthless and emotionless behavior . The Tarc , in fact , did not lack emotions , but believed them to be private and not to be shared with others . Fiercely protective of their culture and sovereignty , the Tarc saw other species as a threat to both of these and , as a result , were extremely isolationist as a society . The Tarc colonized the star systems around their homeworld , making the area a buffer between them and the rest of the galaxy and using their navy , the Ivlacav Gourn , to destroy any intruders . That practice led the species into conflict with the Galactic Empire during the Galactic Civil War . Biology and appearance . The Tarc were a carnivorous species of crustacean that originally evolved from large sea - dwelling creatures . However , evolutionary pressures forced them to adapt to life on land , where they became well adapted to the arid desert environment of the three continents of their homeworld , Hjaff . These adaptations included great tolerance for high temperatures and the ability to go without fresh water for extended periods of time , despite their aquatic origin . Such traits derived from the Tarc being covered entirely in a chitinous exoskeleton that could store water and act as a means of controlling body temperature . The exoskeleton also provided protection from damage but made the Tarc far heavier and bulkier than Humans and humanoids of similar size . However , the added size made them more intimidating . The Tarc were hairless bipeds , possessing two legs and four arms , as well as two eyes and a pair of antenna on their head . The upper pair of arms were dexterous with three fingers on each hand , while the lower arms ended in claws used for fighting . On average adult Tarc stood between 1 . 75 and 2 . 2 meters tall . Despite their size , they had surprisingly quick reflexes , although their weight caused them to be relatively slow on land . Due to their diet of meat , the Tarc never evolved the need for lips , teeth or tongues . Instead , they possessed hollow spikes inside their mouths , which injected acidic saliva into food . Once the food was shredded into smaller pieces , it then was ingested directly through the spikes for nourishment , as the Tarc lacked stomachs . The lack of such an organ meant the Tarc could not digest tough or sinewy meat , so their diet consisted of sand mollusk s and other small creatures with soft flesh native to the deserts of their homeworld . Society and culture . Most other beings generally perceived the Tarc as cold and emotionless , since the species considered the emotions they did have as personal , rarely sharing them with others . They often came across as ruthless , only caring about their own survival , although that was entirely a product of their culture and the environment in which they lived . A Tarc ' s actions were always necessary and decisive , aiming to achieve a specific result within a set time period , often more short term than long . If an action did not achieve the desired result , another was quickly implemented to replace it . Deliberation was rare amongst the Tarc and not highly valued . The Tarc ' s society originally was divided among a large number of nations , each prioritizing the protection of their own sovereignty and culture against the others . Although the Tarc were not a particularly violent or warlike species , international disputes led to many wars when they saw aggression as a logical action to achieve their goals . The Tarc ' s tactics normally consisted of using overwhelming force to defeat and then destroy the enemy in a short period of time , with mercy never being an option . The Tarc only engaged in conflict for what they believed was truly an appropriate action to achieve the goal they sought , very rarely doing so out of anger or hatred , although they were capable of such emotions . However , during combat , the Tarc sometimes became enraged due to their pent up emotions . Whilst in this state they were incredibly dangerous , attacking anything and anyone nearby . The Tarc ' s culture developed as the nations became more advanced and came to depend on each other and the global economy of Hjaff more than that of individual states . The nations eventually integrated into a single union that sought stability . This government was politically a hierarchical system and was led by two political bodies , the continental leadership and the Keddek , an individual planetary leader . The continental leaders were three individuals , each representing one of Hjaff ' s three continents , who acted as advisers to the Keddek and assisted in carrying out the Keddek ' s rule . The Keddek was superior to the three leaders and had near full power over the entire species but had to obey the Hjaff constitution whilst ruling . If not , the continental leaders were expected to overthrow the ruler with their combined military strength and choose a replacement . All positions of leadership within the Tarc political system were held for eight standard years — the equivalent of ten of the Tarc ' s years — before a vote was taken to determine who would next hold the position . All Tarc were expected to vote in these elections ; those who did not faced punishment normally in the form of a prison sentence or indentured servitude . The Tarc possessed a zero - tolerance policy in relation to other species , something that could border on xenophobia , as they saw non - Tarc as a threat to their way of life . That was exacerbated by the Tarc mouth structure , which resulted in the Tarc language being spoken in a series of clicks and clacks from their mouth spikes accompanied by growls and grunts . Besides their own language , the lack of a tongue meant the Tarc could not speak Basic or most other languages , and so communication with other species was difficult . The space surrounding their homeworld in the Colonies was colonized and acted as a buffer between them and the rest of the galaxy , with the Tarc navy — the Ivlacav Gourn — destroying any starships that entered the region . The species attempted no further expansion beyond their defended region , and it was a crime for a Tarc to leave their home system without specific permission . History . The Tarc originally evolved in the oceans of Hjaff before beginning to move onto the shores at an early stage in their development . Once on land , they moved evolutionarily further away from their aquatic origins and geographically deeper into the deserts that made up most of their homeworld . In such harsh conditions , the species developed complex tools to help them survive , and they soon advanced and spread across the planet . The early members of the Tarc species segregated into a large number of different nations of varying size and strength across the different continents of Hjaff . These nations each sought to defend their individual cultures and sovereignty and , as a result , often came into conflict with one another . After a long period of these various international wars , in which the Tarc ' s society and technology slowly developed , each nation gradually came to depend on the others as a global economy formed . Due to such interdependence , the Tarc nations eventually ceased to fight one another and integrated into a single union , lead by a global leader named the Keddek and a body of three continental leaders . Shortly after the formation of the union , the Tarc began space exploration in the surrounding systems of their own Hjaff system . They colonized these regions , taking control of twenty systems and then encountering other sentient life . The Tarc were horrified but not shocked to discover alien life , but they interpreted such outsiders as a threat to their culture . The Tarc immediately retreated and ceased all space exploration , leaving their colonized systems as a buffer between them and the rest of the galaxy . Military outposts were built on many worlds at the edge of their region of colonized space , and the Tarc navy destroyed all intruders on sight . Such policies led to a number of skirmishes between the Ivlacav Gourn and the Imperial Navy during the reign of the Galactic Empire . The Tarc won all such skirmishes , prompting Imperial Moff Joss Leskwin , who governed the region of space containing the Tarc - controlled systems , to form a strike force strong enough to take on the Tarc navy and engage the species in full - scale war . As the conflict escalated , some Tarc suggested that the species should seek aid from the Alliance to Restore the Republic , a rebel force simultaneously in conflict with the Empire in the Galactic Civil War . Those individuals believed the Tarc culture would be preserved better under Rebel control than that of the Empire . However , such Tarc had little political representation or influence . Prominent Iyra Sentientologist Tem Eliss wrote an entry on the Tarc species in his book , " The University of Sanbra Guide to Intelligent Life " , during their conflict with the Empire . In the book he theorized that most likely the Abinyshi species , who inhabited the planet Inysh in the Inysh system close to Hjaff , were the first other sentient species the Tarc encountered . At the time of the book ' s writing , the Keddek on Hjaff was named Visacc . Tarc in the galaxy . Given that the Tarc were forbidden to leave their region of colonized space , very few were found in the rest of the galaxy . Due to the isolated nature of the Tarc and their inability to speak Basic , those Tarc who did leave Hjaff had an incredibly difficult time communicating with other beings , as almost no non - Tarc spoke their language . Given the restrictions on leaving their homeworld , most Tarc found away from Hjaff and its surrounding systems were outcasts or criminals and , as such , often came to work for criminal organizations . They usually found employment as bodyguards , enforcers , bounty hunters , and assassins , due to their intimidating appearance and strength . One such Tarc , active during the Galactic Civil War , was Fascyn , who became an assassin and bounty hunter as part of House Salaktori , the preeminent member house of the Bounty Hunters ' Guild . Fascyn was personally selected by the house ' s CEO to join the organization , as all members were . Behind the scenes . The Tarc were created as a species for West End Games ' , with a detailed description of the race given in the fourteenth issue of the " Star Wars Adventure Journal " . The article , part of the " Alien Encounters " series , was written by Trevor J . Wilson and Craig Robert Carey , and published in 1997 . The article included an illustration of a Tarc by Pablo Hidalgo and roleplaying attributes for the species that favored dexterity , strength , and perception , whilst granting the Tarc average scores in the remaining attributes . Some of the information from the article was then republished in " Alien Encounters " , a West End Games supplement book released in 1998 compiled by Paul Sudlow . The Tarc have received no other mention in " Star Wars " - related media save an entry for their homeworld , Hjaff , in " The Complete Star Wars Encyclopedia " , published in 2008 and written by Stephen J . Sansweet and Hidalgo .
