Muun / Legends Muuns were a thin , tall humanoid species from the frozen world of Scipio , though they also had a large colony on the mineral - rich planet of Muunilinst . The founders of the InterGalactic Banking Clan , the largest banking organization in the galaxy , Muuns were known throughout the galaxy for their excellent financial and mathematical skills . Seeking economic stability , the Galactic Empire exempted Muuns from their wide - spread non - Human persecution , in order to utilize Muuns and their economic finesse . Biology , appearance and traits . Muuns were tall and gaunt humanoids with thin bodies and elongated heads with hairless craniums . They also had pasty - white / pale pink to grey skin , most likely because the vast majority of the species did not like traveling , even on - planet , and usually stayed indoors . Muuns also had tiny ears on the middle of the sides of their heads . In addition they had flat noses , and slim mouths . Muun voices often sound nasally , due to their small noses . Muuns had long arms and legs , making them appear very gaunt . They also had very thin waists and long , thin fingers . Members of the species also had three hearts , one normal heart and two that were consciously controlled , a trait often used to increase blood flow in low temperatures . This also may have contributed to a longer life - span . Muuns were extremely intelligent , and both greedy and cautious when it came to business ventures . They were lured to profitable and vulnerable economic situations or opportunities , yet took long thought before committing themselves to a business deal . Muuns ' talent with money stemmed from their extremely valuable mathematical and statistical skills . Muun children were known to calculate complex mathematical formulas as quickly as most adults of other species could . In addition to being greedy and cautious , Muuns also deemed themselves to be a reserved , mature species , capable of controlling their emotions , and deemed other species as immature , and felt no remorse in exploiting them , if need required them to do so . Muuns possessed a drive to compete with other races and even among themselves , which also contributed to higher rates of economic output anywhere Muuns were located . Muuns also had a fundamental respect for fairness and justice , however , and regarded a contract as almost a sacred trust . Muuns were known to always follow the letter of the law , though often not the spirit . Society and culture . The Muuns believed in tradition and established a culture based on merit and intelligence . A class - hierarchy developed around this worldview , valuing financiers , lawyers , engineers , and diplomats as the highest levels of society . Commoners rarely left the surface of their planet as upward mobility was limited , reserved for only the most gifted of children who passed rigorous examinations . Muun culture , indeed , Muun life , revolved around economy and finance . Intense competition among co - workers encouraged economic growth , increased production , and superior work ethic . Since Muuns tended to shy away from fighting and physical pursuits , Muun society used alternative means for their planet ' s protection , using their vast financial resources to purchase massive floating defense platforms to defend their planet from attack . The InterGalactic Banking Clan ( IGBC ) , a largely Muun - run organization , was known to utilize hired mercenaries to enforce their policies and collect payments and debts . Muun reliance on mathematics leaked over into their language , which was a collection of " um " and " eh " sounds of varying pitch , similar in some ways to Binary . History . Early in their history , the Muuns founded the InterGalactic Banking Clan , which came to span not only the galaxy , but smaller satellite galaxies as well . While Muuns originated on Scipio , they colonized the planet Muunilinst early in the IBC ' s history and made it a major hub of activity . Because of its immense mineral wealth , Muunilinst was used to give weight to the Galactic credit , making its importance in galactic society almost incomparable to many , if not most Core Worlds . Throughout the time of the Galactic Republic , Muuns had a knack for funding potentially profitable enterprises throughout its sector , regardless of ethics or loyalty . Muunilinst provided much of the funding for the nearby Human colony world of Sartinaynian , which , ironically , broke away from the Republic because of anti - alien sentiments . The banking clans of Muunilinst were uninterested in these prejudices . They funded colonies , trade guilds , and corporations all along the Braxant Run . At some point in their history the Muuns also colonized the planet of Mygeeto , which , much like Muunilinst itself , would become wealthy as an important financial center . Eventually , both Muunilinst and Sartinaynian came to be member worlds in the Republic , and Muunilinst became one of the greatest financial powers in the galaxy . The power and influence of the Banking Clan was largely unchecked as the Republic fell into decline and corruption , and with the looming threat of the breakdown of law and order , the IGBC invested in thousands of " Hailfire " droids to discourage customers from defaulting on their loans . Prior to the Clone Wars , IGBC Chairman San Hill was approached by the leader of the Separatist movement , Count Dooku . San Hill helped finance the Confederacy of Independent Systems , believing it very plausible that the Confederacy could conquer the Republic . San Hill also used secret Banking Clan codes used for transferring bank statements and depositing money to clients to establish the Shadowfeed Network , a secret Confederate analogue to the HoloNet , used to distribute propaganda to the galaxy . It was also used as a means to allow Confederate leaders to transmit untraceable and untappable messages to their subordinates , making the Banking Clan an invaluable member of the Confederacy . Consistent with its reputation for playing both sides against the middle , Muunilinst simultaneously backed the Republic and the Confederacy during the Clone Wars . Alliances with the Confederacy , however , led to Separatist forces building droid factories and munitions depots on Muunilinst , over the objections of the native Muuns . Despite its economic importance , the Republic was left with no other option than to invade Muunilinst and destroy the Confederate strongholds . This led to a series of ruinous battles . During the Battle of Muunilinst in 22 BBY , Obi - Wan Kenobi , Anakin Skywalker , and Voolvif Monn retook the planet for the Republic , but at great cost . The battle devastated the Muun cities , sparing none , and led the galaxy to the brink of financial ruin . Muunilinst later became the financial center of the Galactic Empire . Emperor Palpatine harbored no fondness for non - Humans , but the mineral riches of Muunilinst were too important for the stability of Imperial credit and he even had a Sith Master that was a Muun , the last non - Human to rule the Sith Order before the Republic was dissolved . Muuns ' lending and business operations were hampered by harsh Imperial decrees and the presence of Imperial monitors stationed throughout the world ' s financial institutions . Muunilinst was no more loyal to the Empire than it was to the Republic or Confederacy , but found it expedient not to undermine Imperial power , reasoning that , no matter the outcome of the Galactic Civil War , the victor would be forced to keep doing business with the Muuns and the IGBC . It remained part of the Imperial Remnant during the New Republic years , protected by two Golan III battle platforms . Amazingly , but again consistent with their reputation , even while a part of the Imperial Remnant , Muunilinst still became the guarantor of the New Republic credit . This infuriated the Moffs , but they were powerless to move against the IGBC without destabilizing the Imperial credit . During the Yuuzhan Vong War , the alien intruders attacked the Imperial Remnant . In a coordinated strike , the Yuuzhan Vong decimated the forces protecting Muunilinst . The planet itself was bombarded from orbit , reducing it to a wasteland from which the Yuuzhan Vong plucked any survivors for use as slave labor . By 40 ABY , Muunilinst had recovered . Behind the scenes . Though the Muuns first officially appeared in " " , two previous Expanded Universe works contain characters who could easily be retcon ned as Muuns . The first , the animated segment of " The Star Wars Holiday Special " , contains two unnamed characters on Panna who look like Muuns . When asked , Leland Chee specifically stated that the two aliens may be Muuns . Another possible Muun is Lord Graemon , an Imperial - allied banker who is described as " a lean man wearing the traditional Muunilinsti banker ' s shawl and pendant " in " The Hand of Thrawn Duology " . In " " , Muuns are incorrectly depicted as being identical to Humans in loading screens .
