Sluissi The Sluissi were the indigenous sentient species of the planet Sluis Van , located in the Outer Rim Territories . While their bodies above the waist were humanoid , their lower halves were serpentine , long and heavily muscled . Sluissi were noted for their calm temperament , aversion to rushing and impatience , compliance to protocol , no matter how trivial , and their technical aptitude . Like many reptiles , Sluissi could use their forked tongues to sense heat . Renowned for their ability to repair and maintain starships , the Sluissi were active in galactic society almost since the beginning of the Republic . This was because the Sluissi ' s technology was almost on par with other space - faring races such as Duros and Humans . Biology and appearance . Sluissi ' s upper torsos were similar to a human ' s , with two arms , each with four - fingered hands . Their fourth finger was an opposable digit . Their arms had almost winglike extensions of skin , which aided their movement while they were flat on the ground . The bottom half of their body was similar to a snake ' s , with a long , heavily muscled , singular tail . Their bodies were covered in fine scales which ranged in color from light brown to dark green . Other colored scales on Sluissi were not unheard of , however they were quite rare . Sluissi had round black eyes and a swooping , hoodlike fold of tough skin at the back of their heads . They had forked tongues that aided their sense of smell . The average member of the species weighed 60 kilograms . Society and culture . Sluissi were patient , sociable , relaxed , and easy - going beings , famous for remaining calm under pressure . Their patient , calm nature — combined with their seeming inability to become genuinely upset or angry — often baffled , and sometimes even infuriated other species . Extremely industrious , Sluissi loved to tinker with technology and mechanical objects , and Sluissi technicians were able to improve the engine efficiency , power output and system response in even archaic , worn out ships . The Sluissi were extremely methodical , and worked extremely slowly . To them , starship construction was an art form . Although jobs done by Sluissi always took longer than expected , most clients were willing to be patient , because Sluissi technicians could make improvements upon or salvage vessels when no other mechanics could . Even the Empire realized that rushing a Sluissi operation was a bad idea . As well as Sluissese , their native language , Sluissi spoke Basic , though they tended to slur and lisp many words , due to the snakelike structures of their tongues and mouths . Common Sluissi names included Sirlahn Alsek , Vsil Ejahsa , Usahn L ' sehl , Sekae N ' sehnor and Mektiss Risohr . History . The Sluissi joined the Old Republic when it was still relatively young . When Duros and Human scouts first discovered Sluis Van , the Sluissi had only just begun to explore nearby systems with their own lightspeed technology , and they eagerly embraced the concept of greater galactic union . An advanced people , they established a number of major space yards throughout the Sluis sector , including the high tech Sluis Van space facility , as well as on other colonies they had established to spur further interaction with offworld space travelers . They ran efficient operations , where ship crews could find all the service , expertise and upgrades necessary after long journeys . The Sluissi quickly became known as one of the best starship maintenance species in the known galaxy . However , shortly before the outbreak of the Clone Wars , they became disillusioned with the Republic , and were among the first to secede and join the Separatist cause . Nevertheless some Sluissi were aligned with the Republic . After the end of the Clone Wars , the Sluissi lived under Imperial occupation . When this ended , they became valuable members of the New Republic . In 9 ABY , the Imperial Navy launched an attack on three of the planets in the Sluis Van Sector , in an attempt to steal warships from the Sluissi shipyards . The resulting Battle of Sluis Van almost ended in victory for the Empire . However , the " Millennium Falcon " was in the area at the time , captained by Han Solo , and aided both the New Republic military and the Sluissi people . During the New Republic ' s rule , Mammon Hoole included an entry on the Sluissi in his publication " The Essential Guide to Alien Species " . Sluissi in the galaxy . Offworld Sluissi tended to work as tech - specialists , engineers or mechanics , although it was not uncommon to see a Sluissi working as something else . At least one Sluissi was Force - sensitive and served as a Jedi during the Mandalorian Wars . This individual was one of Lucien Draay ' s Covenant Shadow s , a secret force of Jedi of whom all records had been erased to allow them to work undercover . Ten Dorne was a Sluissi who worked on Shantipole Project with Admiral Gial Ackbar . The project revolved around the development of the B - wing starfighter . Shortly before the Battle of Endor , Dorne was captured by Imperials . The experience made her doubt her devotion to the Rebel cause , so she decided to defect and later sold information about the Alliance to the Empire . She was later believed to be working at the Imperial Remnant shipyards on Vosteltig . Sere Lure was an attractive , green - skinned female Sluissi engineer , who worked for Hydrospeare Corporation . Dr . Lure was a rarity ; she was one of very few aliens permitted and willing to work in the development of Imperial technology . Candobar Inglet was the ruler of Sluis Van and the Sluis Sector during the Clone Wars and for several year beforehand . Just before the start of the war , he and his sector defected to the Confederacy of Independent Systems . Other Sluissi included Hass Sonax , a female Sluissi slicer , Corlissi Ludar , the Sluissi senator who pledged Sluis Van ' s alliance with the CIS , Slith Skael , the chief communications technician of the Intergalactic Communications Center towards the end of the Clone Wars , and Secles Uslopos , a male Sluissi councilor to the Twi ' lek crime lord Abdi - Badawzi on the planet Socorro . Alessi Quon was a male Sluissi scientist who worked for the Experi - Tech department of Imperial Intelligence shortly before the Battle of Yavin . Behind the scenes . " " Statue " quo à Sluis Van " , an issue of the French RPG magazine " Casus Belli " , contains additional material on the Sluissi . According to this article , the Sluissi were a calmly methodical species who compensated for physical frailty with technological skill and ingenuity . In contrast to mentions of a Khedive in Clone Wars material , this source says that Sluis Van was governed by an elected parliament of a hundred members , known as the Council , and throughout the New Order , their political consensus was that loyalty to the Empire had brought their world prosperity . According to this material , the Sluissi joined the New Republic in around 6 ABY thanks to a diplomatic mission led by Jonas Stern and Borsk Fey ' lya . The novel " Jedi Trial " incorrectly depicts the Sluissi , Sluis Van , and the Sluis sector as aligned with the Republic rather than the Confederacy .
