Duel on Kiffu The Duel on Kiffu occurred after a failed meeting between Count Dooku , Head of State of the Confederacy of Independent Systems , and Tinté Vos , Sheyf of the Kiffu Guardians . The failed meeting . When Dooku arrived on Kiffu , he met with Sheyf Tinté Vos , proposing that the former Guardian side with the Confederacy . Refusing to be swayed by Dooku ' s firebrand rhetoric , the Sheyf did not side with the Confederacy , revealing her belief that her people would rise to power after the Galactic Republic and the Confederacy had exhausted each other . Dooku , admitting that he feared as much , ordered his acolytes to engage the Sheyf ' s guards and kill her . With that the battle was on . The battle . Though they fought valiantly against Dooku ' s acolytes , the Guardians were sorely outmatched . With a path to the Sheyf cleared , Quinlan Vos advanced on her . However , his hesitation to kill his aunt compelled Kadrian Sey to attempt to do it herself . However , when she leapt at the Sheyf , Quinlan swung out with his saber and killed her . By that act he revealed himself to be a Republic agent . With that , Vos scooped up his aunt fled deeper into her palace with a burst of Force - assisted speed . Dooku pursued , ordering Tol Skorr to finish off the guard . The Sheyf ' s secret . As Tinté Vos screamed for him to unhand her , Quinlan came to a stop in a deserted room deep within the palace . Revealing to her that he was a Republic agent , he only received accusations of being involved in a Republic scheme to subjugate and control Kiffu and Kiffex . As Vos and his aunt argued , Dooku suddenly appeared , claiming to have known all along that Quinlan was an agent . As Vos took up his lightsaber and charged at the Count , Dooku parried the blow , and stated that Vos didn ' t know what he was protecting . Before the duel could continue any further , Dooku caught Vos in a Force grip and lifted him off the ground , while depriving him of his lightsaber . As Dooku dropped Quinlan , Tinté accused him of being a liar and warned Quinlan to disregard anything he said . Dooku countered by telling Quinlan to not believe what the Count said , but what the Jedi saw . Vos realized Dooku was referring to the psychometric abilities possessed by the Kiffu people . Vos stated that this ability couldn ' t be used on a sentient , living being , only inanimate objects . But Dooku told Quinlan to augment the ability with the dark side of the Force to allow him to do so . Quinlan did so , and proceeded to forcefully ' read ' his aunt . First he found out that Tinté had murdered her brother so as to usurp his position as Sheyf . Then he found out that she made a deal with the Anzati journeying to Kiffex , following the call of Volfe Karkko . However , to seal the deal , the Anzati required ' blood of her blood ' , i . e , a relative of her ' s to feast on . Finding out that Tinté had sacrificed his parents to the Anzat , Quinlan broke the connection and angrily questioned her as to why . Tinté Vos revealed she did so to gain custody of Quinlan , so as to mold him into an heir . She also explained why she murdered her brother , considering the former Sheyf too friendly with the Republic and the Jedi . Quinlan declared her a murderer who deserved to die , and Dooku encouraged this sentiment , stating that justice demanded it . The Count proceeded to return Vos ' lightsaber so the Jedi might ' deliver justice ' himself . Quinlan Vos butchered his terrified aunt , at last gaining full acceptance into Dooku ' s cadre of acolytes , as it was clear now his conversion was no deception . Aftermath . Following Dooku ' s and his acolytes ' victory , the CIS proceeded to subjugate Kiffu . Zac ' ryah Vos , also a Guardian , was killed in the process .
