She became a member of the Baran Do Sages , a Force - based organization on Dorin , and later joined the Hidden Ones , a secret sect of the Baran Do dedicated to preserving their knowledge . She was present in the sect ' s caverns in 43 . 5 ABY , when former Jedi Grand Master Luke Skywalker — recently exiled from Coruscant and the Jedi Order for dereliction of duty — and his son , Jedi Knight Ben Skywalker , traveled to Dorin to speak with Baran Do Master of the Order Koro Ziil to learn more about Jedi Knight - turned - Sith Lord Darth Caedus ' s fall to the dark side of the Force . They eventually discovered the Hidden Ones , and Ithia greeted Ben upon their arrival . The Skywalkers met with Ziil , who had become the sect ' s leader , and Ziil revealed that , in order to protect the sect ' s secrecy , no one would ever be allowed to leave the caverns . Luke eventually turned Ithia and the Hidden Ones against Ziil and defeated him in a battle of Force powers , and Ithia and the Hidden Ones returned to the surface of Dorin . Biography . Early life . A female Force - sensitive Kel Dor from the helium - rich planet of Dorin was a member of the Baran Do Sages , a Force - based organization for Kel Dor on Dorin . During her time with the Sages , she was trained in fighting technique , which was relatively rare among the Sages , and she was considered one of their most skilled combatants . She frequently dueled fellow Sage Charsae Saal — also one of the Baran Do ' s best fighters — and rarely lost to him . Sometime prior to 43 ABY , the female Kel Dor decided to join the Hidden Ones , a secret sect of the Baran Do tasked with preserving the Baran Do ' s knowledge so that if the organization was ever destroyed , it could be reinstated . In doing so , she changed her name to " Ithia , " as the Hidden Ones required their members to change their names and accept that they were dead to the outside galaxy , resigning themselves to their duties as members of the sect . During her time in the Hidden Ones ' home , a series of caverns deep below Dorin ' s surface , Ithia became resigned to her " death " and did not feel the need to practice her skills . As such , her strength of will and Force powers diminished over time . In 43 . 5 ABY , former Jedi Grand Master Luke Skywalker — recently exiled from the galactic capital of Coruscant and the Jedi Order for dereliction of duty — arrived on Dorin with his son , Jedi Knight Ben Skywalker , to find Master of the Order Koro Ziil . They hoped to find out more about why Jedi Knight Jacen Solo had turned to the dark side of the Force . Upon their arrival in the Baran Do temple , however , they were told that Ziil had died , and they decided to stay and train with the Baran Do Sages . Before long , Saal , now the Sages ' senior combat instructor , decided to join the Hidden Ones . He held his " dying ceremony , " in which a Sage pretended to die and then traveled to join the Hidden Ones in their caverns . Luke was not fooled by Saal ' s apparent death , however , and , after searching the site , he and Ben found Saal alive and well . Realizing that Ziil was also likely still alive , they agreed to travel with Saal to the Caverns of the Hidden One . Ithia was present when Saal and the Skywalkers arrived in the caverns ; she greeted the younger Skywalker and revealed to him that he would have to choose a new name , considering Ben Skywalker to be dead . There , the Skywalkers found that Ziil was indeed still alive and had become the Hidden Ones ' leader , taking the title of simply " the Hidden One . " They spoke with him , and he revealed to them that in order to protect the sect ' s secrecy , no one who entered the caverns was ever allowed to leave . Leaving the Hidden Ones . A few days after joining the sect , Saal — who had taken the name of " Chara " — dueled with Ithia in a set of three matches . Ithia had grown weaker than Chara , and he defeated her in every match . Observing , Luke developed a theory that the Hidden Ones — by turning their backs on life , energy , and vitality — had turned their backs on the Force , causing their powers to weaken . Ithia later went to Ziil ' s throne chamber when the Skywalkers announced that they would be holding a naming ceremony , in which new members of the Hidden Ones took new names . Once the Hidden Ones had gathered in the chamber , however , Luke revealed that they intended to rename some or all of the Hidden Ones instead of themselves . Luke went on to present his theory about how the Hidden Ones were weakening ; to prove it , he suggested that Ben duel Chara . Ithia provided Ben with a hardwood staff , and he and Chara , the latter similarly armed , proceeded to fight . Chara — though by far Ben ' s superior , having instructed him in combat technique at the temple mere days before — lost the duel , as he lacked the will to win . Ziil , however , refused to accept the turn of events , claiming that Luke had brainwashed Chara into believing that he was growing weaker , but the other Hidden Ones began to agree with the Skywalkers . Angered , Ziil revealed that he had told those on the surface that the Skywalkers had died when a cave collapsed ; as such , they would no longer need their oxygen - nitrogen canisters . Without the canisters , the Skywalkers would die from Dorin ' s helium - rich atmosphere within a couple of days . The Hidden Ones protested , and Ithia spoke out in support of the Skywalkers ' idea . She told Ziil that she believed that the " experiment " that was the Hidden Ones had failed . Finally pushed over the edge , Ziil attacked Luke , and the two engaged in a duel of Force powers . The duel , won by Luke , left Ziil exhausted and collapsed on the floor . Ithia was the first to rush up and check on him ; she determined that he would recover . She continued to tend to Ziil as Ben triggered a series of explosives , sealing off the tunnel that was believed to be the only entrance or exit from the caverns , and revealed the many lies Ziil had told the Hidden Ones . Although Ziil continued to be defiant , Burra , one of the eldest members of the sect , gave in and revealed the location of a secret turbolift chamber that led out of the caverns . Ithia and the Hidden Ones returned to the Baran Do on the surface , and the Skywalkers left Dorin soon after . Personality and traits . Ithia was renowned as one of the best combatants of the Baran Do Sages , and , until Chara joined the sect , she was the best fighter in the Hidden Ones . She knew that Luke Skywalker ' s theory on the Hidden Ones ' waning powers was correct , as she recognized that the Hidden Ones were weakening and realized that her own skills had diminished greatly as well . When few others would speak up against Ziil , Ithia was one of the first to confront the Hidden One with these problems and debated in open support of the Skywalkers . Despite verbally opposing Ziil , however , she was concerned for him after his fight with Luke left him collapsed on the ground , as she was the first to reach his side to assess his condition . Powers and abilities . Ithia was one of the few Baran Do to be trained in combat , as fighting techniques were not required for the Sages . She became a very skilled combatant and was said to be the Baran Do ' s best ; when dueling with Chara , she would consistently win at least two out of three matches . When she joined the Hidden Ones , however , she was forced to turn her back on life , and thus her fighting skills and her connection to the Force weakened . In 43 ABY , when she again dueled with Chara , he defeated her in each of their three matches . Behind the scenes . Ithia was created by " Star Wars " author Aaron Allston for his first novel in the nine - book " " series , " " , released March 24 , 2009 .
