House Praji House Praji was a wealthy Core Worlds family originally from Kaikielius . The Prajii were one of the original signatories of the Galactic Constitution , and over the twenty - five thousand years of the Galactic Republic ' s history , produced numerous military officers , politicians , financiers , and several Jedi Knights . Throughout their history , they maintained a pronounced rivalry with House Vahali , another noble house of Kaikielius . From 4800 BBY , the Prajii were established at the Praji Estate on Coruscant , where they established influence in the Bank of the Core , and in the lead - up to the Clone Wars , the Coruscant Ministry of Ingress . During the Galactic Civil War , they re - established themselves on Kaikielius at the expense of their ancient rivals , the Vahalii , from where they continued their influence on galactic politics despite the destruction of the Praji holdings on Coruscant during the Yuuzhan Vong War . History . Early history . The earliest known progenitor of the Prajii was Tyler Sapius Praji , the governor of the pastoral Core World of Kaikielius . Tyler Praji was one of the signatories of the Galactic Constitution , the founding document of the Galactic Republic , in 25 , 053 BBY . On Kaikielius , House Praji was one of the Triad , the three most powerful of the Great House s of the planet ' s aristocracy . Together , the Triad had a powerful voice on Coruscant , though perhaps owing to Tyler Praji ' s role in the foundation of the Republic , House Praji had the greatest ties to the capital . House Praji maintained an ancient rivalry with the other houses of the Triad , House Vahali and House Juoni , which was believed to date from the colonization of Kaikielius . However , House Juoni was destroyed during the First Alsakan Conflict of 17 , 000 BBY after it backed Alsakan while its rivals supported Coruscant , leaving Kaikielius to the Prajii and Vahalii . For another five thousand years , the Prajii ' s power grew at home even as Kaikielius ' galactic influence dwindled . In 11 , 660 BBY , during the Twelfth Pius Dea Crusade , Commodore Daymont " Veracity " Praji commanded a fleet in the Pius Dea - dominated Republic Navy . Daymont Praji led the bombardment of Zarracina III after the native Zarracine s refused to accept annexation and conversion to Pius Dea rule . Exodus to Coruscant . From 11 , 000 BBY , Kaikielius rivalled with Koros for influence in the Core Worlds , but infighting in the Koros system , and between the Great Houses on Kaikielius , prevented either from gaining an advantage . In 5000 BBY , however , the nine planets of the Koros system were unified by Empress Teta , putting Kaikielius at an extreme disadvantage . The Prajii ' s homeworld underwent rapid urbanisation and industrialisation in a desperate attempt to keep up with Koros , resulting in the development of the infamous " ring - cities " , which were soon abandoned to poverty and crime . Fast losing money on Kaikielius , House Praji moved much of its operations to Coruscant , and after suffering badly during the Quake Years around 4800 BBY , abandoned the planet for good , leaving rule of the increasingly - ungovernable planet to House Vahali . House Praji ceased to exist as a formal entity , and having sold their ancestral holdings on Kaikielius at a loss , the family had no real estate except on Coruscant . It would not recover economically for centuries , with many scions of the family falling into obscurity owing to financial mismanagement . However , the Prajii increased their informal influence by gaining election to high office , and eventually became the majority shareholders of the Bank of the Core . By 4225 BBY , the Prajii once again held great influence on Coruscant . Emppu Praji - Barck served as a Republic Minister of State for sixty years , while the family had produced several Jedi Knights by marrying sons to daughters of the Draay family . Derrica Praji was one of these Jedi around this time , training under Master Vandar Tokare on Ossus before , to the fury of his relatives , becoming part of a joint Republic - Jedi expedition to Kaikielius . Emppu Praji - Barck , Derrica ' s great - aunt , had continually filibustered Senate debates on intervention in the Kaikielius system : all government positions were now filled by the Vahalii , but the planet was " de facto " controlled by criminals , pirates , and Hut " kajidics " , and the Prajii were content to let their rivals destroy themselves before they moved back in to pick up the pieces . However , the Republic had discovered that the Odominic " kajidic " had been supplying weapons to both sides in the war between gangs and police on Kaikielius . Now a matter of Republic security rather than one of law enforcement , the planet ' s criminal elements were ousted in the Kaikieli Reconquista . During the course of the Reconquista , Derrica Praji discovered evidence in the capital Kesipli that Emppu Praji - Barck had committed sedition in urging the Odominic to supply both sides of the gang war . For the sake of his family , Derrica chose to destroy the evidence , though House Praji ' s objective of seizing sole power on Kaikielius had come to naught . Derrica cut all contact with his family in the aftermath and returned to Ossus to be named Jedi Knight . Plutocrats . Despite the failure of their strategy on Kaikielius , the Prajii expansion continued apace from 4225 BBY as they accepted Coruscant as their home and increased their influence in the Bank of the Core . Following the abolition of the aurodium standard the Bank of the Core became a key backer of the Republic Treasury Reserve , and for millennia a Praji would always sit on the BOTC Executive Board . Over the centuries , the Prajii increased their ties with the rest of the patrician class through intermarriage : centuries before the Battle of Yavin , Lithio Motti married a Praji heiress to secure startup capital for his megonite moss - mining enterprise on Phelarion . The Motti family would dominate that industry for centuries , and during the Galactic Civil War , one of their number , Thalassa Motti , even married into the Eriadu Tarkins . The Prajii ' s financial influence resulted in a political scandal sometime prior to 60 BBY : Supreme Chancellor Vaila Pecivas attempted to appoint Jideon Praji as her Minister of Finance . However , since Jideon was also Executive Board Chair of the Bank of the Core , the appointment was seen to create a conflict of interest , and holomedia uproar and a Senate inquiry forced him to resign after just days in the post . By the start of the Clone Wars , the Prajii had grown to such wealth that the Praji Estate , near the Bank of the Core Plaza in Coruscant ' s Financial District , dwarfed provincial capitals on Outer Rim planets . Thousands of offices for the family ' s employees encircled a park large enough to land a " Venator " - class Star Destroyer , which was maintained by its own chapter house of Ho ' Din gardeners . The Rise of the Empire . By the last century of the Galactic Republic , House Praji ' s patriarch was Tannon Praji . Tannon was a great patron of the arts and built his own fortune separate to House Praji ' s while continuing the investment in the Bank of the Core . When Palpatine became Supreme Chancellor in 32 BBY , one of his first appointments was to make Tannon Second Minister of the Coruscant Ministry of Ingress under First Minister Zelebitha Effhod . Both were soon forced to deal with the pressures of large numbers of refugees displaced by the Separatist Crisis , and Tannon took the decision to close Coruscant ' s borders to new immigrants indefinitely . Tannon soon became First Minister after Effhod ' s death from Quannot ' s Syndrome just as the Clone Wars began . Tannon was troubled by the decisions he had to make as the war progressed , though the Refugee Relief Movement cast him as an uncaring elitist , particularly after he denounced the destruction of art treasures in the Museum of Light on Tandis Four as an atrocity . As First Minister he oversaw efforts directed by COMPOR to deport " en masse " Aqualish , Gossam , and other species whose homeworlds had sided with the Confederacy of Independent Systems . This led him to be the target of numerous assassination attempts , once by Aqualish , and another by Zarracine s . Consequently , he took the Bank of the Core ' s Special Agent Ottegru Grey , who had already foiled a number of Separatist attempts to destabilise the bank , as a bodyguard . Other significant Prajii during the Clone Wars were Tannon ' s brother Griff , whose son Nahdonnis would become a prominent Imperial Military officer , and Tannon ' s wife Maree and their daughter Onnelly . While many of the Coruscant Prajii in this era were stereotyped as idle rich or career bureaucrats , a number did military service during the war : the Kalandar Installation was renamed " Fort Praji " in the honor of Colonel Collin Praji , and Moff Praji rose to command the GAR ' s Fourth Outer Rim Army . Following Operation Durge ' s Lance , which saw Kaikielius conquered by the CIS , Tannon was forced to deal with refugees displaced from the Core Worlds itself . Shortly afterwards , Palpatine declared the foundation of the Galactic Empire . In the new Imperial hierarchy , Tannon oversaw the transfer of prisoners from captured CIS worlds and the movement of transients into new construction projects . Maree and Onnelly Praji were resettled at the " Emerald Splendor Estates " on the Deep Core world of Byss . The relocation was nominally part of a much broader " recolonization effort " intended to attract the wealthy and powerful . In reality , the world was Emperor Palpatine ' s private retreat . While there , Onnelly , Maree , and others like them were kept entertained , but unknown to them , Palpatine was secretly draining their Force energy in order to sustain himself . Later history . Many of its members used their money and influence to enter into the higher - levels of the Republican and Imperial governments . The family donated a genetic template for the Imperial stormtrooper development program . Behind the scenes . " Tinker , Tailor , Soldier , Praji " uses " Prajii " as the plural form of Praji .
