Rhinnal Rhinnal was a planet in the star system of the same name in the Darpa sector of the Core Worlds . Orbited by two moons and located in the Ringali Shell , the region of space along the Perlemian Trade Route near the Ringali Nebula , Rhinnal possessed almost no axial tilt and a near - circular orbit , giving the planet very little seasonal variations . Encased in a planet - wide ice age tens of thousands of years before the Galactic Republic ' s collapse , Rhinnal had begun to thaw by the time it was one of the Core Founder s of the Republic in 25 , 053 BBY , having been settled by Humans from Notron . A colony of nearby Esseles for much of its history , Rhinnal soon gained a reputation as a medical wonderworld , with a Jedi chapter house and the Rhinnal State Medical Academy in the capital of Rhire producing some of the galaxy ' s best doctors . Renowned for its beauty and pristine environment , Rhinnal also developed a textile industry in addition to its pharmaceutical and cybernetics industry , and the native Rhinnalians were known for their fierce loyalty to their clans . Freed from Esseles ' control with the rise of the Galactic Empire , Rhinnal eventually overthrew its governor Phadreas Kole in 7 ABY and joined the New Republic , supplying its doctors and medical expertise to help halt crises such as the outbreak of the Krytos virus and the Death Seed plague . Rhinnal willingly accepted thousands of refugees during the war with the extragalactic Yuuzhan Vong species , though transports full of some of those same refugees were used as ammunition against the capital of Coruscant ' s shields by the Yuuzhan Vong during their capture of Coruscant . Description . The fourth planet in orbit around the star Rhinnal in the Rhinnal system , Rhinnal was located in the region of the Core Worlds known as the Ringali Shell , a string of star systems along the Perlemian Trade Route that were near the violet - colored Ringali Nebula and whose night skies were lit up by the same nebula . Situated along the Perlemian between the planets Esseles and Ralltiir , Rhinnal was located in the Darpa sector , and it was orbited by two moons . The terrestrial planet ' s diameter was 12 , 900 kilometers , and it had a 27 - hour day and a 357 - day year , with standard gravity , a breathable atmosphere , and a climate that ranged from chilly temperate to arctic . Tens of thousands of years before the fall of the Galactic Republic , Rhinnal was experiencing a planet - wide ice age that slowly faded over the course of centuries , with the glaciers exposing the planet ' s landmasses and leaving behind mountains , valleys , and crystal - clear lake s as they retreated . Rhinnal ' s rocky continents were marked by the narrow finger - like bays that split the high cliffs along their coasts , giving the shorelines a fringed appearance when viewed from above . The planet experienced virtually no axial tilt and had a particularly circular orbit , resulting in very insignificant seasonal variations , and much of the planet was covered by glaciers , tundras , and frozen river s . The equatorial regions of Rhinnal were home to mossy slopes and evergeen forests , and the planet ' s ambient temperature was significantly lower than other worlds to the point where every visitor was advised to bring a jacket . Snow fell frequently during the night on Rhinnal , but the reduced amounts near the equator typically melted by morning . Rhinnal was also prone to electromagnetic storms that swept across the equatorial regions several times a year , and engineers had begun to use terraforming to increase the planet ' s self - sufficiency by the time of the Galactic Empire , since all attempts to farm share crops on any part of the planet never succeeded . The wooly gabal , the rare snow falcon , the limbed fish known as firehead s , and the fireheads ' predators , the tenticulon s , were among the creatures native to the world . History . Early history . Tens of thousands of years before the rise of the Galactic Empire , Rhinnal reached the end of a planetary ice age ; by the time sleeper ship s carrying Human colonists from the planet Notron reached the Ringali Shell sometime after 27 , 000 BBY , the planet ' s glaciers had retreated from the equatorial regions , leaving Rhinnal habitable . Sometime before the Galactic Republic ' s founding in 25 , 053 BBY , a warship from the planet Dellalt crashed near the planet ' s southern pole , and it became buried in the ice over the following millennia . Rhinnal was one of the Core Founder s of the Republic , but for much of the planet ' s history , it was a colony of the Esselian Empire and ruled by a governor from its neighbor Esseles . When Rhinnal ' s capital of Rhire was still only a supply outpost on the banks of the Frieste River for hyperspace explorers heading out along the Perlemian , the Jedi Order established a chapter house to the west of the city , a simple , spired structure that could hold almost a hundred patients . By the time of the Cold War between the Republic and the Sith Empire , Rhinnal ' s native snow falcon was on the verge of extinction , and hunting the birds was a crime that was punishable with life imprisonment . The planet also had a thriving textile industry by that point , though a transport carrying Ayelixe Fabrico textiles once exploded in the atmosphere over the planet and scattered its cargo for kilometers . However , during the Cold War , the Sith Lord Darth Ikoral returned to the larger galaxy and embarked on a series of attacks against both the Empire and the Republic , viewing neither of the governments as acceptable due to his extreme belief that the Sith pureblood species was superior . Ikoral ' s flagship , the " Red Reaper " , attacked the planet and destroyed a enclave of the Jedi Order on Rhinnal . The enclave ' s destruction was sensed by Grand Master Satele Shan all the way on Tython in the Deep Core , and the Republic patrol frigate " Toron Voq " was destroyed by the " Red Reaper " when it was sent to investigate Rhinnal . The Jedi chapter house was expanded decades before the Clone Wars between the Republic and the Confederacy of Independent Systems , and Qui - Gon Jinn was one of the Jedi who delivered building materials to the chapter house because none could be procured from Rhinnal ' s ice - covered surface . The Corellian Zahara Cody was one of many who attended the Rhinnal State Medical Academy in Rhire , and the diagnostic database of the 2 - 1B surgical droid model was programmed by a team of surgical experts from the Academy . In 33 BBY , the Jedi Master Adi Gallia was grievously injured on Esseles , and the Jedi Knights Vel Ardox and Noro Zak brought Gallia to Rhinnal for treatment . The Knights arrived at Rhinnal just after an electromagnetic storm had knocked out Rhire ' s power grid and all of the planet ' s communications satellites , preventing the Padawan Obi - Wan Kenobi from making contact with Rhinnal over any of the standard channels , so his Master Qui - Gon Jinn decided to travel to Rhinnal to investigate . The Talz pilot Bama Vook brought the pair to the Rhinnal system , but when the chapter house did not respond to their hails , the two Jedi descended to the complex . However , when they learned of the storm , the two were also prevented from leaving , as another storm was due in three hours . In 22 BBY , the Allied Tion Historical Society ' s " Cradle of the Galaxy " exhibit of pre - Republic artifacts began a tour of the Core Worlds on 13 : 4 : 1 on Ralltiir , and it arrived on Rhinnal five months later on 13 : 9 : 1 . The exhibit was showcased in the Rhire Concourse of Humanity and History for five months before it moved on to Esseles on 14 : 2 : 3 . Two weeks after the tour ' s announcement on 13 : 3 : 14 , the State Medical Academy released their findings on the status of air pollution in the middle - class districts of the galactic capital of Coruscant , and two months later , the Academy ' s staff were among those health officials who criticized the high - gravity planet of Columus ' s marketing campaign towards the severely overweight . The Empire and beyond . The Clone Wars ran from 22 BBY to 19 BBY , and at their end , Supreme Chancellor Palpatine reformed the Republic into the Galactic Empire and eradicated the Jedi Order . However , because of the planet ' s reputation , the chapter house on Rhinnal was spared from destruction unlike the other chapter houses across the galaxy , and it was taken over by Rhinnal ' s doctors . Under the Empire , Rhinnal was granted marginal independence , as the Esselian Empire had collapsed shortly before the Clone Wars due to financial difficulties . The Moff of the Darpa sector , Jander Graffe , reined in Esseles ' power and overturned Rhinnal ' s classification as an Esselian colony , installing Phadreas Kole as an Imperial governor . Kole was largely off - hands in his leadership , leading Rhinnalian opposition to the Empire to be muted until 4 ABY : six months after the Alliance to Restore the Republic killed Palpatine at the Battle of Endor , the newly - formed New Republic captured the nearby planet of Brentaal IV , rattled Rhinnal ' s citizens . An organized resistance movement soon formed and succeeded in overthrowing Kole in 7 ABY , and the planet became a valued member of the New Republic , sending its best doctors to combat the virulent Krytos virus that was ravaging Coruscant at the time . Six years later , they once again contributed their medical aid when the Death Seed plague threatened to spread across the galaxy , and when the extra - galactic Yuuzhan Vong species invaded the galaxy in 25 ABY , Rhinnal took in thousands of refugees from the Outer Rim Territories . After the planet received ten thousand refugees from Ord Mantell , Governor - General Amer Tariq was forced to reroute two thousand more to the Ruan system , and he turned down Ambassador Leia Organa Solo ' s request to land more refugees , but sent her in the direction of Ruan . The Yuuzhan Vong began to capture refugees around Rhinnal during the months before their attack on Coruscant in 27 ABY , during which they used transports carrying refugees to bombard the capital ' s shields . Inhabitants . Rhinnalians , as the inhabitants of Rhinnal were known , were primarily Human , with Humans making up 92 % of the population of 55 million . The planet ' s cities were centers of healing and business , producing doctors of great skill and renown , and Rhinnal was also a player in the textile industry , though the planet ' s Rhinnalian rugs were considered more of a luxury due to their high cost . The planet had a reputation among the Core Worlds of having an atmosphere of exclusivity , one which was reflected in manners , clothing , and decor , and Rhinnalians were considered experts in passive aggression , routinely snubbing off - worlders and aliens . Rhinnalian industry was also centered on cybernetics and pharmaceuticals in addition to their medical expertise . Rhinnalians were markedly different to other Core Worlders , as they were fiercely loyal to their ethnic clans and major governmental decisions were made by the heads of those same clans . Rhinnalians were also fond of elaborate ceremonies ; a total of eighty - four days of the planet ' s calendar were set aside for celebrations and holidays . Native Rhinnalians typically wore colorful , patterned clothing that had been hand - woven from the wool of the gabal . Rhinnal ' s medical community was more cosmopolitan , with most graduates of the Medical Academy being offworlders . Rhinnalian culture valued honor and style , traits that inspired their fascination with ceremony . Locations . As much of the planet was still covered by glaciers , the inhabitants of Rhinnal mostly inhabited the world ' s more temperate equatorial regions . Rhinnal ' s capital city of Rhire , with over seven million inhabitants , lay along the north banks of the Frieste River in the southern fringes of the equatorial band , and it was home to both the Jedi chapter house and the Rhinnal State Medical Academy . Street traffic in the city was largely light , as most of the residents used the underground shuttle network known as the Circulation Network to get around Rhire , and hydroelectric energy plants along the banks of the Frieste powered the city . The State Medical Academy covered many square kilometers in the heart of Rhire , with three working hospitals and dozens of classrooms , clinics , and laboratories . The three hospitals each catered to a different group : one specialized in treating Humans , a second humanoid aliens , and a third treated aliens whose biology was radically different than humanoids . To the north of Rhire was the Zirfan glacier and the Sennes Mountains , where native Rhinnalian clans hunted the wild gabals for their wool and schools of fireheads lived in the ice of the glacier . V - Fin submersible ice breaker s were frequently used by recreational tourists to tour the planet ' s oceans and poles , though cheaper submersibles were used when exploring the less dangerous riverbeds and submerged caves of Rhinnal ' s waterways . The clan village of Austogie was located to the south of Rhire in the territory of the Kieger clan . Behind the scenes . Rhinnal was first mentioned in the Into the Core Worlds segment of " Star Wars Adventure Journal 7 " , published in 1995 , which gave an overview of the planets in the Ringali Shell . It continued to receive mentions in a number of sources and materials , but the planet ' s first actual appearance was in " " , which was released in 1999 . The 2003 roleplaying guide " Coruscant and the Core Worlds " mistakenly used its picture of Rhinnal for the planet Ralltiir , a mistake that was repeated in the 2008 " The Force Unleashed Campaign Guide " .
