this young Jedi Knight was a Kiffar who was discovered by Ki-Adi-Mundi and allowed to leave Kiffex to train on Coruscant. Note that Star Wars: Darkness indicates that Quinlan was discovered by Master Tholme. His parents, Quian and Pethros, were members of the Guardians of Kiffu, but were killed by a group of rogue Anzati under the command of Volfe Karkko. His remaining family hoped he would remain loyal to Kiffex first, and Quin vowed to return to his homeworld as often as possible. As a Padawan, Quinlan trained with Obi-Wan Kenobi, and they fought side-by-side with their Masters during the Stark Hyperspace War. His psychometric talents were quite strong, and Quin was quickly raised to the level of Jedi Knight after being trained by Jedi Master Tholme. Quinlan had just started training Aayla Secura as a Padawan when he was captured on Nar Shaddaa by Pol Secura. His memory was erased with an intense overdose of glitteryll, although he still had contact with the Force. He lacked his old discipline, however, and came very close to the Dark Side of the Force before returning to Coruscant. He was later dispatched by Mace Windu and Saesee Tiin to infiltrate the planet Dathomir and locate a connection between the Witches of Dathomir and the disappearance of the planet Ova. He hoped to learn more about matriarch Zalem and her clan, in an effort to link the temples on Ova to those on Dathomir. Quin, distinguished by the stripe of yellow tattoo which crossed his face horizontally, was taken captive and enslaved by Vonya, and earned special notice when he killed a guardian whuffa worm singlehandedly. He was offered a chance to serve as Zalem's personal bodyguard, but he hestiated enough to be relegated to keeping wild kwi. In doing so, Quin learned that of the ancient Kwa and their Infinite Gates. He also learned that, because of his killing of a guardian worm, he was now the guardian of the Star Chamber on Dathomir. He was later recaptured by Zalem, but was rescued by his friend Yag Shushin and Ros Lai, who was herself a Dark Side adept. They were unable to prevent Zalem from unleashing an Infinity Wave at Coruscant, but Quin managed to destroy the command module of the Star Chamber on Dathomir, eliminating the Wave before it hit the planet. He also brought Ros Lai to Coruscant as a prisoner, in the hopes of returning her to the Light Side of the Force. Shortly afterward, Quinlan was recalled to Kiffu by his aunt, the Sheyf Tinte Vos, to help discover the increase in attacks by feral Anzati. Quinlan also discovered that his former Padawan, Aayla Secura, was on Kiffex, under the control of the Dark Jedi Volfe Karkko. With the help of several other Jedi Knights, including Quinlan's former teacher Tholme, Quinlan overcame the Dark Side and defeated Volfe Karkko in one-on-one combat. Instead of returning to Coruscant with the rest of the Jedi, Quinlan left Kiffu with Vilmarh Grarhk, following Master Zao's belief in letting the Force guide his path. He was later reunited with Aayla when Master Tholme was captured by Kh'aris Fenn and imprisoned with Nat Secura on Kintan. They managed to defeat the Morgukai warriors, Tsyr and Bok, and rescued Tholme and the Secura heir. Upon returning to Coruscant, Quinlan Vos was elevated to the rank of Jedi Master, for his work in freeing Master Tholme and helping resolve the upheaval on Ryloth due to Kh'aris Fenn's actions. As the Clone Wars broke out, Quinlan decided that the best way to help was to go underground and infiltrate the Separatists. He adopted the alias of Korto Vos and managed to help the Jedi in a number of arenas, specifically on Brentaal. As Korto, he worked to infiltrate the Separatist network as part of an elaborate plan conceived by the Jedi Council. In a daring move, the Council dispatched Agen Kolar to arrest Quinlan and bring him back to Coruscant for justice. Kolar was unaware of the plan, and was chosen because he would never actually kill Quinlan, despite any "crimes" he might have committed. When Kolar failed to recover Quinlan, it gave him a chance to abandon the Korto Vos alias and reveal himself as a Jedi who had become disillusioned with the Republic and the Jedi Order. After he killed Tookarti, he completed his transformation by delivering his "resignation" to the Jedi Council in a holographic message from a secure location, so as not to be traced. He then traced down Count Dooku on Antar 4, and did what was necessary to win the Count's trust. While on Antar 4, Quinlan learned that Dooku had been negotiating with Sheyf Tinte for the rights to establish a Separatist base on Kiffu. He had managed to win a measure of Dooku's trust when they traveled to Kiffu to complete the negotiations with Tinte. When Dooku ordered Tinte's death, Quinlan couldn't stand by and allow it. He killed Kadrian Sey before she could assassinate Tinte, then took the old woman and fled. However, Dooku apprehended them and forced Quinlan to read Tinte's mind. After learning of Tinte's treachery - how she had murdered her brother, of her dealings with the Anzati Jedi Volfe Karkko, how she allowed the Anzati to keep the prisoners on Kiffex quiet by allowing the Anzati to feed on them, and how she sealed the pact by giving Quinlan's parents to Karkko as sacrifices - Quinlan could no longer control his anger. Although Tinte claimed to have only wanted Quinlan to follow in her footsteps, he refused to listen. When Dooku presented Quinlan with a lightsaber, he eagerly cut down Tinte Vos, killing her on the spot and solidifying his turn toward the Dark Side of the Force. The Jedi Order feared that his turn was complete, but Quin continued to maintain that it was a necessary aspect of his cover. Some six months before the First Battle of Coruscant, Quin was reunited with Obi-Wan Kenobi aboard the Titavian IV, after Obi-Wan answered the ship's distress call. The pair barely escaped from Asajj Ventress and Skorr, and Quin then traveled to Rendili with Obi-Wan. After his brave efforts during the Rendili Fleet Crisis, Quinlan was allowed to rejoin the Jedi Order. Unknown to his friends and the Order, Quinlan's actions were all part of a much more devious plan of Count Dooku's design. After having turned Quin to the Dark Side, Dooku planned to have Quin return to the Jedi Order, as a traitorous double agent. Quin, however, finally realized that the Jedi Order was his true home, and he eventually abandoned the plans of Count Dooku. He kept this change of heart to himself, however, hoping to use his position within the Separatists to locate the second Sith Lord who was working with Dooku. Information gathered from Salje' Tasha led Quinlan to believed that the second Sith was Sora Bulq, and Quinlan agreed to serve as Oppo Rancisis' second-in-command at the Siege of Saleucami in order to get close to Bulq. On Saleucami, he was forced to assume command of the mission when Rancisis was killed by Sora Bulq. His fellow Jedi believed that he was privy to what Master Rancisis had planned, but Quinlan was ignorant of what had been done while Rancisis was in his battle meditation. So, Quinlan was forced to create his own battle plan, which ultimately succeeded in eliminating Sora Bulq. However, the loss of Rancisis weighed heavy on everyone's minds. In the wake of the battle on Saleucami, and after learning that Khaleen Hentz was pregnant with his child, Quinlan vowed to leave the Jedi Order when the Clone Wars were over. Vos later led the forces of the Grand Army of the Republic into battle on Boz Pity, during the Outer Rim Sieges. In the wake of the First Battle of Coruscant, Vos was dispatched to Kashyyyk as part of the task force led by Jedi Master Yoda. However, when Darth Sidious revealed his true nature and killed Mace Windu, he sent out communications to the various clone commanders to execute Order 66. Upon hearing the order, clone troopers opened fire on Vos, utterly destroying the defenseless Jedi Master.
