Jon ( farmer ) Jon was a Human male farmer who lived on Dantooine near the Jedi Enclave with his daughter , Ilsa , during the years before the Jedi Civil War . Ilsa was killed by a group of Mandalorians in 3956 BBY due to her defiance against their assumed authority . In his rage , Jon demanded that the Jedi of Dantooine deliver justice , but this was denied as it was considered by the Jedi that he was only seeking revenge . Inadvertently , that justice was delivered by the former Sith Lord Revan , who struck down the Mandalorians in self defense during his trials to become Zhar Lestin ' s Padawan . Appeased , Jon returned to his farm , and resumed work . Biography . The murder of Ilsa . Jon was a well - known Human farmer who lived near the Jedi Enclave and the future capital Khoonda on Dantooine during the years before and in the Jedi Civil War . At some stage in his early career as a farmer , he sired a daughter , Ilsa . Jon was always concerned for Ilsa , as she was often given to being compulsive , and there was always the threat of the Mandalorian raiders who plagued the fields of Dantooine , looting farms at random , and leaving people with barely enough food and money to survive . Sometimes , they were known to go even further , killing farmers on a whim . Their intent was to take over the complete infrastructure of the farms surrounding the Jedi Enclave , and they were loath to stop at robbery and pillage . The Jedi , who were the only form of law on the planet , did next to nothing to stop the Mandalorians , due to the fact that they were dealing with the pressing issue of the Jedi Civil War . This led some farmers to defend themselves , which in turn escalated the problem . One day , when Jon was tending the fields with Ilsa , a group of Mandalorian raiders , led by the lightsaber - toting Sherruk , arrived at Jon ' s farm . Instead of sacking his establishment immediately , they demanded that Ilsa hand over anything of value . When she defied them , they murdered her before Jon ' s eyes . Enraged , but helpless , Jon was left with the corpse of Ilsa as the Mandalorians fled the scene . Lobbying to the Jedi Knights . Outraged and grief - stricken , Jon demanded justice from the Jedi . He ordered that they hunt down the Mandalorians and destroy them , not only to avenge the death of Ilsa , but so that the farmers of Dantooine could live in peace , and without fear of constant attack and destruction . But the Dantooine Council believed that Jon only sought revenge and so did not grant him audience . In addition , they were chiefly concerned with the ongoing Jedi Civil War . Fuming , Jon spent most of his time outside the Jedi Enclave , asking any Jedi who would walk by for help . However , like the Council , none of the Jedi obliged . Jon also sought help through other channels . He informed all of his fellow farmers of his plight , but even they did not help him in his quest . Instead , they gave him vocal support , and were quick to cite to strangers the case of Ilsa ' s murder . While , as Jon pointed out , the death of Ilsa could have been a springboard for a unified resistance against the Mandalorian raiders , the opportunity was wasted . Meeting Revan . One day , Jon met Revan , an amnesiac former Sith Lord who sought to re - commence Jedi training . Revan had made himself known on Dantooine , under his new alias , and so Jon naturally requested that the newcomer help him . While Revan did not initially rebuke Jon , he was not one for wanton violence , and so continued on his set tasks . Inadvertently , Revan was forced to kill several Mandalorians in combat , due to their ambushing him on the fields around the Enclave . Returning to Jon with the news , Revan inquired deeper into the situation . Jon told him that the carnage would not stop until the ringleader , Sherruk , had been killed . Despite Revan ' s constant avoidance of the lure of the dark side , he set out after Sherruk , with the justification that he would be helping the farmers . On the grassy plains of Dantooine , he confronted Sherruk , and urged him to refrain from his actions . When Sherruk refused , Revan killed him and his cronies in combat . Revan returned to Jon with the news , which calmed the volatile farmer down . Jon insisted that Revan take his reward of 1000 Republic credits , and , satisfied , Jon returned to his farm , a broken man . Personality and traits . Jon was a light skinned Human male with black hair and blue eyes . Following the murder of his daughter , Jon turned to violence , demanding the guilty parties be killed . Other farmers in the Enclave community did not act surprised at Jon ' s attitude towards the Jedi Council and the Jedi in general following the murder , and they were hesitant in joining any resistance movement that he might form . Jon himself avoided creating a resistance movement , as he had a complete lack of faith in his combat abilities . However , Jon lusted for the blood of the Mandalorians . He demanded their destruction , and even requested that their hearts literally be torn from their bodies . Jon would not accept the decisions of his peers nor the Jedi , and would constantly demand justice , despite Dantooine not having a fully fledged legal system . When the Mandalorian leader , Sherruk , was killed , Jon suddenly became docile , no longer abrasive and bloodthirsty . Behind the scenes . Jon first appeared in the 2003 video game " " from BioWare , and was created by David Falkner , Steve Gilmour , Casey Hudson , Drew Karpyshyn , James Ohlen , Preston Watamaniuk , and Derek Watts . He is the instigator of one of Revan ' s optional side quests in the game . " Knights of the Old Republic " is the only source in which Jon appears , but he has been mentioned in the game ' s and in 2008 ' s " The Complete Star Wars Encyclopedia " . Alternate resolutions . If Revan is attuned to the dark side , he will oblige Jon and hunt down the Mandalorians . The player , as Revan , can also demand more money from Jon or refuse his offer , but he will still give the player 1000 credits . It is also possible to ignore Jon completely , although interaction with him is required for 100 % completion of the game .
