Undercity Ambush The Undercity Ambush was the Jedi Coalition ' s first action taken against Jacen Solo , the co - Chief of State of the Galactic Alliance and Sith Lord . At first the plan was to either a capture or neutralize Jacen , but changed to planting a tracking device on Solo after realizing that the first intentions weren ’ t realistic . The ambush was a failure , with Darth Caedus killing Thann Mithric and nearly killing the famous Jedi Master Kyle Katarn . The Legends however , were able to plant the tracking device on the Dark Lord . Prelude . Following the Devastation of Kashyyyk , Luke Skywalker gave Kyp Durron the task of planning a mission against Jacen Solo . Kyp later informed Luke that a team of 4 Jedi including a guide would ambush and capture Solo in Coruscants undercity as he was entering or leaving the Senate Building . There would be a droid piloted shuttle meant to draw away their pursuers as they were escaping with the captive Chief of State . Kyp told the Grand Master that if the capture didn ' t work out as planned ; they would kill Jacen to prevent him from causing further damage to the galaxy . Luke reluctantly agreed and then asked to meet Seha Dorvald , the teams guide through the undercity . Her loyalty was in question because she helped Ben escape out of the Jedi Temple under Jacen ' s orders as well as giving him information on the Jedi . She came forward about her actions when she heard about the Massacre on Ossus . But Luke accepted her after talking with her and learning of her actions during the Invasion of the New Jedi Temple . Kyp insisted that Luke lead the mission but he refused . Luke knew he would attack with hate and that Ben would follow his example and be lost to the darkness . He instead appointed Jedi Master Kyle Katarn team leader . The Jedi team which consisted of Katarn , Jedi Knights Valin Horn , Thann Mithric , Kolir Hu ' lya , followed Seha Dorvald as they crawled thorough the undercity ' s waste pipes to get to their positions . After several hours a convoy of three airspeeders showed up . One was a black GAG speeder , the second was a heavily armored civilian speeder , and the third was a GAG troop carrier . The convoy stopped and troops began securing the area . Then the civilian speeder opened and a YVH droid came out holding a crate containing Solo ’ s daughter Allana followed by Jacen himself . As the group headed toward the Senate Building , Katarn gave the order to attack . Attacking the Chief of State . Caedus heard what sounded like four grenade launchers firing . He told the droid to take Allana to safety and watched as dazzle grenades blinded his troops . The four Jedi then approached Jacen and Katarn offered surrender , which Solo quickly rejected . Darth Caedus nearly laughed at the Jedi as he realized that , with the exception of Katarn , they were no match for him . Katarn also realized it would be very difficult to complete their objective and told Seha to linger behind the fight and plant a tracking device on Jacen ' s cloak . At the very least , the Jedi would know of Jacen ' s whereabouts . Katarn began the duel with a strike that Caedus easily deflected as he Force Pushed Hu ' lya into Mithric . Katarn tried to strike Caedus again , but he dodged the blade and kicked Valin Horn in the chin . Katarn nearly kicked Caedis in the head but he managed to partially avoid it , catching a scrape on his cheek . Caedus retaliated by slashing at Katarn ' s leg , but his strike was blocked by Kolir . Then the Jedi escape shuttle entered the plaza closely followed by three GAG airpeeders pursuing it . Caedus attacked Horn so that he would flinch into the path of Mitric , which he did . As the two Jedi collided , Caedus force pushed Hu ' lya into Katarn , who threw his lightsaber at Jacen so he could catch Kolir with both hands . Caedus swatted away the lightsaber and threatened to torture the Jedi if they didn ' t reveal the location of their secret headquarters . Hearing this , Katarn made one final plea to Jacen to realize his actions , asking if he knew who he was anymore . The Sith Lord simply responded that he did , and it was the Jedi who had no idea who he was now . Caedus sensed Mithric and Horn preparing to attack so he yanked Kolir with the force so he blocked their path . Katarn advanced toward the Sith Lord , but remained unaware of the many GAG speeders attacking their escape shuttle overhead . Caedus used this to his advantage by yanking down a speeder and launching it down toward the Jedi Master . Katarn expected another force push and realized too late that a speeder was flying towards him . The speeder hit Kyle in the back and knocked Kolir to the ground . Katarn flew forward and slammed into Caedus as he buried the hilt of his lightsaber into his chest . Seha used the chaos to her advantage and merged the patch with Jacen ' s cloak as the three remaining Jedi charged Solo . As Seha left , she pulled Master Katarn to safety . The GAG troopers ’ sight had begun returning and fired at Mithric and Horn . Valin deflected the bolts at Jacen , grazing his leg . Mithric then charged Jacen as he fell and began to beat down his parries . Caedus then realized that he was losing focus and hadn ' t fully recovered from his duel with Luke . Also , Mithric sent more and more blaster bolts towards him . Caedus waited until another bolt flew towards him and deflected it into Mithric ' s chest . Caedus decapitated him with a single lateral blow . After sharing a few words with Horn , Caedus watched as the Jedi fled . Aftermath . Seha , Horn , and Hu ' lya carrying and injured Kyle Katarn managed escape through the undercity and made it back to the Jedi hideout . Caedus picked up Mithric ' s head and observed it before dropping it on the ground . He was disappointed that he could not find the body of Kyle Katarn . Kyp Durron later informed Luke of the failed ambush and the success of the tracking device . This device would help the Jedi locate Jacen before the Battle of Centerpoint Station , but it was eventually discovered by Patra Tebut .
