Derrica Praji was born into the wealthy and influential family House Praji during the time of the Galactic Republic and was the grand - nephew of Emppu Praji - Barck , the Minister of State of the Republic . From an early age , Praji learned of his family ' s rivalry with House Vahali , an aristocratic family from the planet Kaikielius . When Praji was twelve years old , he was discovered to be Force - sensitive and joined the Jedi Order . He became the Padawan of Jedi Master Vandar Tokare and went to live with Tokare on the planet Ossus . Tokare allowed Praji to correspond with his parents , but always emphasized to Praji that as a Jedi , his allegiance to the Republic should come above his allegiance to his birth family . Over time , Praji began to care less for the material aspects of his former life with his parents , but he continued to encounter references to his relatives in historical texts , or hear about minor Praji celebrities in the media . By 4225 BBY , Praji was close to completing his Jedi training , when trouble on Kaikielius caused him an emotional dilemma . For decades , pirate activity in the Kaikielius system had been posing a serious problem for House Vahali , but Emppu Praji - Barck had prevented the Republic from interfering . However , in 4 , 225 BBY , the Hutt Odominic kajidic began supplying black - market arms to Kaikielius , causing a war in the planet ' s ring - cities between the police and the criminals . The Republic was forced to intervene and Master Tokare volunteered himself , Praji and his other Padawan to participate in the Kaikieli Reconquista , the campaign to retake Kaikielius from the criminal factions . This posed a problem for Praji , as he realized that by participating in the campaign , he would be aiding House Vahali and so , helping to undermine centuries of plotting by the Prajii to weaken their rivals . Praji thought about his dilemma as he traveled through hyperspace to Kaikielius , eventually deciding that he didn ' t want to disobey his master and refuse to take part in the campaign just because of an inherited family vendetta in which he had no personal involvement . For three months , Praji and the two other Jedi commanded Republic troops on Kaikielius , leading attacks on the most criminal - infested ring - cities . However , while in the planet ' s capital , Kesipli , he discovered some datatape s that again put his allegiance to the Republic at odds with his loyalty to his family . The tapes revealed that his great - aunt , Emppu Praji - Barck , had caused the problems on Kaikielius , by manipulating the Odominic into supplying arms to both sides in the conflict . With the evidence he had found , the Republic could charge Praji - Barck with sedition , so Praji destroyed the tapes with his lightsaber . Afterward , Praji severed contact with his family and when the Republic was eventually victorious on Kaikielius , he returned to Ossus and was made a Jedi Knight . Thousands of years later , Doctor Gabrel Treon wrote about Derrica Praji in " Tinker , Tailor , Soldier , Praji " , a history of the Praji family that was included in the " Byblos Journal of Historical Science " . Personality and traits . While Praji trained to become a Jedi , he felt obligated to his family , but couldn ' t imagine a situation where he would have to choose between them and the Republic . However , during the campaign of Kaikielius , he fought with a clear conscience after deciding that his allegiance lay with the Republic and the Jedi . Despite this , Praji still felt some loyalty toward his family and wished he had never learned of their influence in causing the conflict on Kaikielius . Behind the scenes .
