Y ' bith The Y ' bith ( or " Ghost Bith " ) were a subspecies of the Bith . The ancestors of the Y ' bith were merely Bith who occupied the domed city of Nozho on Clak ' dor VII , but a civil war between that city and the planet ' s capital , Weogar , would inadvertently create the subspecies . Weogar launched a biological attack against Nozho , destroying most of the wildlife and killing many of the citizens . Those who survived suffered from mutagenic irregularities , leading them to be branded as " Ghost Bith . " The Y ' bith eventually left what remained of Nozho , and relocated to Clak ' dor IV . Bioengineers were able to stabilize the mutation of the Y ' bith , but the beings took some time to adapt to their newfound genetic features . Developing their own culture , the Y ' bith were never fully embraced by the Bith , who cited the volatile biochemistry of the subspecies which made them violent and aggressive . Nevertheless , the Y ' bith strove to be accepted by the galactic community as a whole , and their city of New Nozho became a notable trade port . The Y ' bith also aided in the rebuilding efforts that took place in the wake of the Yuuzhan Vong War . Biology and appearance . The physical features that were unique to the Y ' bith and not possessed by the Bith themselves were a direct result of the biological attack on the city of Nozho . The Y ' bith featured orange , sensitive skin , poor eyesight , strong hands and feet , thicker bones , and ductile mouth structures . In addition to that , they possessed volatile biochemistry , making them prone to violence and aggression . Society and culture . The Y ' bith always strove to be accepted by their Bith cousins , even when faced with harsh refusal . As a whole , they resolved to not be satisfied with anything but acceptance from the Bith . They saw their story as one of success , and hoped that the galaxy as a whole would agree with their point of view . As a result , the Y ' bith were constantly trying to prove themselves as a people . History . At some stage in the early history of the Bith , a bitter rivalry brewed between two prominent cities on Clak ' dor VII : the capital city Weogar , and the domed city of Nozho . In approximately 300 BBY , relations between the two cities broke down over a dispute pertaining to a stardrive patent . As a result , the Nozho - Weogar War broke out , causing insurmountable damage to the biosphere of Clak ' dor VII . During the war , Weogar launched a biological attack against Nozho , effectively destroying the city , as well as causing mutations in both the populace and the nearby wildlife . Those surviving Bith that had suffered mutations were in a minority , though ; most of Nozho ' s populace had been killed in the attack . The irregularities that were a result of the mutations were consistent amongst all the survivors , leading to the creation of what was essentially a subspecies of the Bith . In the wake of the devastating attack , the survivors , dubbed " Y ' bith , " or , in Galactic Basic Standard , " Ghost Bith , " lived in domed , hermetically sealed cities that had been built in the ruins of Nozho . In time , they departed the ruins , and Clak ' dor VII altogether , instead choosing to settle on the world of Clak ' dor IV . There , the Y ' bith established the city of New Nozho . While the bioengineers amongst the Y ' bith were able to stabilize the mutation , the populace found it difficult to adapt to their new physical features and traits . The Y ' bith were tolerated by the Bith , but they were never openly embraced by them . Although some would claim that the Bith ' s reluctance to accept the Y ' bith was borne from guilt over the Nozho attacks , the Bith themselves denied the accusation . They instead cited the volatile biochemistry of the Y ' bith as their reason for apprehension . Nevertheless , the Y ' bith strove for acceptance not just from the Bith , but from the wider galactic community . New Nozho itself would eventually become a thriving trade port . Y ' bith in the galaxy . As they were constantly striving for acceptance from the galactic community , the Y ' bith spread to worlds other than Clak ' dor IV . As a result , they formed notable minority presences on worlds , such as Nar Shaddaa , and the galactic capital , Coruscant . During the Galactic Civil War , Graven R ' ube , a member of the race , was present at Chalmun ' s Cantina , in 0 ABY . Later , on both Nar Shaddaa and Coruscant , they aided in the rebuilding efforts in the wake of the Yuuzhan Vong War . Behind the scenes . The species of the Y ' bith first appeared , albeit unidentified , in " The Star Wars Holiday Special " " Cantina scene . " They would go unused for several decades , save for scant appearances in the non - canon computer game " " , where they were used as generic non - player characters . In 2006 , the species was identified and fleshed out by Evan Burger ( writing as " ShadowCultist " ) through the StarWars . com feature , " What ' s The Story ? " Burger , noting the visual similarity between the species and the Bith , decided to make them a mutant offshoot of the latter , and in doing so based their name , " Y ' bith , " on the original . Looking for a way to explain the mutation , Burger searched Wookieepedia for a suitable catalyst . He found one in the Nozho - Weogar War , which had originated in Troy Denning ' s " " , originally published in 1989 . Burger continued to build upon established elements in the Expanded Universe , including mentions of the Ghhhk from , and the Yuuzhan Vong War from R . A . Salvatore ' s " Vector Prime " . While the mention of the Ghhhk was cut from the final entry , the Yuuzhan Vong War reference was kept . Burger ' s intentions in mentioning the war had been to tie the Y ' bith into the modern Expanded Universe . When describing the physical traits of the Y ' bith , Burger wanted the mutations to be both a blessing and a curse to the species , giving them positive and negative traits . In order to further differentiate the Y ' bith from the Bith , Burger wrote them as violent and temperamental beings , far removed from what he perceived as pacifist tendencies in the Bith . He made even more ties to the Expanded Universe with his mentions of Clak ' dor IV , originally mentioned in " " , and Nar Shaddaa , from " Dark Empire " . Burger originally named the capital of Clak ' dor IV " Nozho II , " in reference to Nozho from " Galaxy Guide 4 " . The name was later changed to " New Nozho " by StarWars . com staff . Burger ' s entry was later used , with a few minor alterations to change the tense , in 2008 ' s " The Complete Star Wars Encyclopedia " . In the Star Wars Blog article , " " , the unidentified Y ' bith that appears in " The Star Wars Holiday Special " was finally given the name of " Graven R ' ube " .
