Adnerem The Adnerem were a tall , thin , humanoid species of mammal native to the pleasure planet of Adner in the Yataga sector of the Expansion Region . Descended from scavenger - hunters , they had large triangular heads with wide eyes and a large lump in the center of the forehead called an echo chamber . Their thin arms each ended in four talons with no opposable thumb . Adnerem society was based on small , non - genetic social units known as steri , the singular of which was steris , who dwelt together in steri - house s . The members of a steris were known as sterisi , and individual couples who formed a close friendship within a steris were known as a sterika . An Adnerem ' s status was judged entirely by the status of his or her steris , and different steri sometimes battled for balance of power in a conflict known as a raid - war . As a species , Adnerem were generally antisocial and remained independent from the rest of the galaxy ' s economy , although their homeworld was a tourist trap with many theme parks and casinos . During the Galactic Civil War , the largest of these casinos , the Red Lisken , was run by an Adnerem named Etsero , who had ties to the gangster Jabba the Hutt and to various Imperial sympathizers . Those Adnerem who left Adner often remained together in their steris and found group occupations . Steri away from their homeworld usually worked as management in large corporations , criminal organizations , or mercenary agencies , such as the Interstellar Strike Force . Biology and appearance . The Adnerem were a species of tall , slender , omnivorous mammal who normally stood between 1 . 8 and 2 . 2 meters tall . Originally descended from a scavenger - hunter precursor species , they were humanoid with many features in common with the Human species , such as a bipedal gait , upright posture , and two different sexes . While they had a mouth and a nose similar to those of Humans , they had distinctive triangle - shaped heads with no ears , a narrow face and a wide brain pan , which supported a large lump on top of their skull . The lump was a firm , hollow echo chamber , which functioned as an ear for the species , although Humans often mistkook it for a tumor . An Adnerem ' s skin was wrinkled in texture , dark gray in color and completely hairless across their entire body , except for a single small vestigial patch of hair at the back of the skull . The species possessed only four fingers on each of their hands , lacking an opposable thumb . The nails on each finger could grow incredibly long and sturdy . Adnerem ' s eyelids evolved to be narrow to protect their pair of eyes — which were usually light colors such as blue or green — against the twin suns of their homeworld of Adner , in the Yataga sector of the Expansion Region . Society and culture . Adnerem culture was based upon that of their ancient scavenger - hunter ancestors , who were semi - social and banded together in tribes that ranged in size from five to twenty individuals . The Adnerem themselves upheld the same group culture with a society based around socioeconomic social units of five to one hundred individuals , with the groups traditionally consisting of sixty - four adults whom were not necessarily related to one another genetically . These groups were known as steris individually , with the plural being steri and those within a steris known as its sterisi . The members of a steris lived together in a steri - house , which normally took the form of a one or two floored disc - shaped building designed to evenly spread heat . Maintenance and housekeeping duties were shared amongst the sterisi , or another steris was employed to carry them out if the steri - house owners were wealthy enough . The building was divided into two areas , public and private , with individuals known to the steris allowed in the public section but none except the sterisi allowed in the private rooms . Adnerem were born into a steris and raised by caregiving sterisi — not necessarily their parents — within the steri - house until the age of six years old . At that point , the child was transferred into an education - steris to be broadly educated and assessed until the age of fourteen . At that point , the child chose an initial vocation . The next ten years of an Adnerem ' s life were spent training in the chosen occupation and paying back the steris for costs incurred during child - rearing . At the age of twenty - four , an Adnerem ceremonially left the steris and chose which steris to join as an adult . Most steri offered special incentives for their own sterisi to rejoin them , which resulted in roughly half of all Adnerem remaining with the steris they had been born into . Once the decision had been made , it was rare for an Adnerem to leave the chosen steris due to the fact that such a departure resulted in a forfeit of all assets associated with the abandoned steris and carried a slight stigma — although leaving was still seen as socially acceptable . Only Adnerem who had been promised far greater opportunity or status in another steris ever considered such a change . The Adnerem devoutly followed a system of systematic pragmatism such that any Adnerem who wished to increase his or her position did so by improving his or her steris . That endeavor was mainly accomplished by increasing the steris ' s influence and wealth , usually through trade with other steri . Most Adnerem worked hard at this task , although usually out of self - interest . Larger steri sometimes had smaller steri as clients whom they paid to gather resources for them , a position that the more powerful steri rarely abused . A less common way for steris ' s status to change was for them to engage in raid - war s . These were small conflicts between two or more steri , the goal of which was to weaken the enemy and so lower their status . Powerful steri engaged in such activities if they and another steris had conflicting goals , and smaller steri looking to make a name for themselves or to rise up against a powerful steris abusing its power might band together and engage in the conflicts . The battles were almost always short - lived and small in scale , with the objective never being total annihilation of the enemy , due to the fact that a weakened steris might prove useful later as an ally to the victor . Due to the steris system , the species had no social classes or social discrimination against either gender , and each individual was judged purely based on the status of the steris and his or her earned status within it . Adnerem therefore had particular difficulty understanding the concept of ranks and social positions used by other species . Despite this handicap , particularly wealthy Adnerem grew their nails to an extremely long length to show that they need not work . Female Adnerem often differentiated themselves from the males by growing their single patch of hair long and braiding it . The species generally wore clothing typical of many other humanoid species throughout the galaxy , particularly robes . Although all personality types were found amongst the Adnerem , most were cool , collected and patient , and so appeared calm and dispassionate in nature . However , internally they were far more intense but simply did not show it . As a race they were also , in general , asocial and introverted , choosing to spend the majority of their spare time on their own or occasionally in very small groups of five or less . In larger groups , it was rare for any to speak , making public areas on their homeworld almost totally silent . On the other hand , two Adnerem alone could become as active and talkative as a group of ten individuals of another species . Occasionally , a pair within the same steris formed an incredibly close friendship known as a sterika . Sterika were non - sexual in nature , but the two individuals became so close that they considered themselves one entity . The reason for such pairings was unknown to the galaxy at large , although they usually occurred spontaneously after a period of stress for one or both of the Adnerem . Sterika were not sought out by Adnerem as other species sought love ; however , Adnerem not in a sterika sometimes seemed to envy those who were . In total , only about ten percent of the Adnerem population at any one time was in a sterika ; apart from such pairings , it was rare for Adnerem to become emotionally attached or form a strong bond with other individuals , whether of their own species or others . Such social distancing often led others to see Adnerem as remote and manipulative . Long - term immersion in galactic society eventually resulted in Adner ' s technology level catching up with the galactic standard . The Adnerem kept themselves separate from the galactic economy and remained financially isolated , investing heavily in remaining self - sufficient and independent from any kind of imports or investments offworld , with only specialty goods and information being imported in large quantities . The species ' main income came from the entertainment industry they maintained on Adner , as well as a number of other planets that consisted primarily of pleasure and gambling establishments . For over two thousand years , the casinos on Adner were incredibly popular with offworld tourists , with hundreds of thousands flocking to the planet solely to visit them each year . The casinos , run by some of the most powerful steri , became adept at catering to the large number of visitors ' needs , and employed mainly highly trained non - Adnerem as workers . History . Adnerem evolved from a species of primitive scavenger - hunters on the planet of Adner . Their ancestors originally lived in small tribes of five to twenty individuals . As the Adnerem developed socially , they remained highly group - oriented , and their groups became social units known as steri . Outsiders first reached the area of space where Adner was located between 8000 BBY and 5500 BBY . Members of the Duros species were the first to encounter the Adnerem on Adner . Nevertheless , offworld contact had little effect on their culture except for slowly introducing new technology . Adnerem culture kept the same steris - based system , and major historical events on Adner continued to be simple power shifts between different steri . Adnerem in the galaxy . Adnerem generally preferred to remain at home on Adner and compete amongst themselves rather than the rest of the galaxy . Many Adnerem worked in the management of the casinos on Adner . One such individual was Etsero , who lived during the reign of both the Galactic Empire and New Republic . Etsero ran a casino named the Red Lisken , which was one of the largest establishments on Adner . He came to be indebted to Jabba Desilijic Tiure , a powerful Hutt crime lord who ran his illicit empire from the planet of Tatooine . After the Hutt ' s death at the Battle of the Great Pit of Carkoon , in 4 ABY , the debt shifted to a separate party , who had Imperial loyalties . The situation led to the Adnerem being included on a document called " Wanted by Cracken , " a list of wanted criminals and Imperials sought by Airen Cracken , a general in the New Republic . Etsero was a known associate of fellow criminal , the Human Theol Dunoche , who rescued two Twi ' lek women from slavery on the planet Ryloth and brought them to work at Etsero ' s casino on Adner . Adnerem who left their homeworld almost always did so with other members of their steris . Some steri took up interstellar trading , running individual large cargo ships or fleets of smaller craft . A small number of steri hired themselves out to large galactic corporations as management teams on projects of small or medium size . One steris that left Adner set itself up as a mercenary company known as the Interstellar Strike Force . The steris acted as the command and control , while highly trained non - Adnerem were hired to act as the special operation units . Another Adnerem at large became a mercenary ; the Adnerem made the acquaintance of Bitthævrian Colonel Quaal Tavier Catharius and joined the m ' Yalfor ' ac Order — an anti - Republic military order on the planet Guiteica — that Tavier led . The mercenary became part of a four - person leading committee for the order , as well as one of only two non - Bitthævrians in the organization . Some steri turned their business skills to crime and operated small - scale criminal organizations , rarely larger in size than a few star systems . Such Adnerem criminals performed business quietly and eliminated threats and obstacles so as to draw as little attention as possible , often maximizing profit by having a broad range of small , easily hidable incomes instead of making big , risky attempts at a single large pay off , such as a bank robbery . One such Adnerem ended up on the planet Tresidiss , a haven for criminals that was privately owned by Herglic criminals who ran a large number of gambling establishments there and tolerated the illegal activities openly performed by the criminals who frequented the world . Behind the scenes . The Adnerem first appeared as a species in " Wanted by Cracken " , a sourcebook written by Louis J . Prosperi , which was released by West End Games in 1993 for their " Star Wars " . The book contained a list of individuals to act as opponents for player characters in the game , including Etsero , an Adnerem , although the book gave no details about his species apart from their homeworld . The image used for Etsero was concept art drawn by artist Nilo Rodis - Jamero for the character Bib Fortuna in . However , the design was not selected for use in the film . The same sketch had previously appeared in the 1983 concept art book " " . It also appeared in the 1993 book " Monsters and Aliens from George Lucas " , written by Bob Carrau , alongside another Rodis - Jamero Bib Fortuna concept sketch . The images accompanied a holiday newsletter from a family named the Lingsnots , in which they detailed the activities of the three Lingsnot children , Ussto , Miiliki - spoorr and Ciption , over the past year . The aliens were never identified as Adnerem , and nothing in the letter referenced Adnerem culture — for example , the Lingsnots were a " family " instead of a " steris . " Material from " Monsters and Aliens from George Lucas " is considered non - canon unless such material is referenced in later publications . The image of the second Lingsnot character was used in the book " The Illustrated Star Wars Universe " to represent a character named Po Ruddle Lingsnot , but his surname was the only link to the holiday letter , leaving the family ' s canon ical status unclear . Another Adnerem , drawn by Mike Vilardi and based on the Bib Fortuna concept art used for Etsero , was pictured in the 1994 West End Games sourcebook " " . Another West End roleplaying book , " Alliance Intelligence Reports " , written by Bill Smith and published in 1995 , mentioned an Adnerem mercenary as member of the M ' Yalfor ' ac Order . In 1996 , author Timothy S . O ' Brien gave the species an entry in his article " Alien Encounters , " published in " Star Wars Adventure Journal 11 " , also published by West End Games . The article gave a far more detailed account of the species ' biology and culture . It reused Rodis - Jamero ' s Bib Fortuna concept art and included another image of an Adnerem drawn by Scott Neely . The article provided role playing statistics for the Adnerem , which showed they favored perception and knowledge , but were weak in technological aptitude . Etsero was mentioned in another West End Games book , " No Disintegrations " , published in 1997 . The article from " Adventure Journal 11 " was republished in a reduced form in the book " Alien Encounters " in 1998 , a collection of alien species compiled by Paul Sudlow . The book also revealed that Adnerem were mammals in its appendix , which listed all species in the book by type . The Adnerem received an entry in " The Complete Star Wars Encyclopedia " , published in 2008 and written by Stephen J . Sansweet and Pablo Hidalgo .
