Skirmish at the Shi ' kar Straits This skirmish at the Shi ' kar Straits took place around 21 BBY , during the Clone Wars . After the aftermath of the battle on the planet of Kiros , Jedi Generals Obi - Wan Kenobi and Anakin Skywalker were continuing their search for the lost population of Togrutas . After Grand Master Yoda indicated that the missing Kiros population of Togruta was blamed on the Jedi , Kenobi suggested that they should search the Zygerria system for further investigation . Skywalker orchestrated the mission , while his Padawan Ahsoka Tano , Kenobi and Captain CT - 7567 joined him . After departing in the " Twilight " , they journeyed into what remained from the Shi ' kar homeworld and found a " Zygerrian Freighter " - class vessel named the " Fate ' s Hand " . The group docked and were greeted by the ship ' s captain , Onyx . As Skywalker and Kenobi used Tano as " merchandise " for the Zygerrian slavers , they soon activated their lightsabers and fought them . Clone troopers backed them up and the Zygerrians were soon forced to retreat back into the cockpit of the freighter . Tano , who faked injury , was captured by the Zygerrians and was held for random . Skywalker , Kenobi , and Rex journeyed back into the freighter and rescued Tano . They forced Onyx to reveal the location of the missing Togruta population , and were told that they ' re being traded in an auction on the Zygerrian homeworld . Prelude . Around 21 BBY , the aftermath of the Battle of Kiros caused the Togruta population of the planet to disappear . Grand Master Yoda contacted High General Obi - Wan Kenobi and General Anakin Skywalker to alert them of the disappearance of the population . While the Jedi were blamed , Kenobi noticed that something was out - of - place . He then revealed that their was activity in the Zygerria system , which was brought to Yoda ' s attention . The Zygerrians were no stranger to the elder Jedi Master , and an investigation in their system would be necessary . Staging the mission to the Zygerria system , Kenobi warned Skywalker that they had to be cautious , however , the Jedi Knight declined . His reaction to Kenobi ' s statement concerned Tano . Kenobi revealed to her that her master was once a slave , and he tried to push that part of his life behind him . Eventually , Skywalker suggested that they would go around the trade routes that led to Zygerria , to avoid detection . Skywalker , Kenobi , Tano , Captain CT - 7567 , and a group of clone troopers left in the " Twilight " and journeyed to the Zygerria system . The group ventured through the Shi ' kar Straits , the remains of the once Shi ' kar homeworld . Skywalker urged Kenobi that they should have brought their battlegroup and depart to Zygerria , although Kenobi told him that with " luck , " they would be able to find a Zygerrian slave freighter . Skywalker ' s astromech droid , R2 - D2 , alerted CT - 7567 that there was a freighter approaching in the distance . After the clone captain told Skywalker , the Jedi Knight told Tano to charge up their main weapons , however , Kenobi denied the use of an attack and suggested that they negotiate with the slavers on the freighter . Skirmish . After contacting the freighter , the ship ' s captain , Onyx , allowed them to enter , under the impression that the group were " amateurs . " The " Twilight " docked with the frighter and Skywalker , Kenobi , and Tano journeyed inside the Zygerrian slave freighter . Onyx and few Zygerrian armed slaves greeted the group . The Jedi used Tano as " merchandise , " to impress the Zygerrians , although their negotiation were cut short after Skywalker activated his lightsaber . Skywalker ordered Onyz to surrender , although he declined and began to fire at the Jedi Knight . Kenobi and Tano soon followed and activated their lightsabers , which shocked Onyx and his men . More blaster fire consumed the area , and soon clone troopers approached to backed the Jedi up . Zygerrian slavers approached from behind and almost killed Kenobi , although CT - 7567 warned him of the attack . Kenobi then ordered an retreat , however , one slaver took out a missile launcher and fired it at Tano and CT - 7567 . The blast damage caused the shield door — which allowed the Jedi and clones to re - enter the " Twilight " — to fall near the clone captain . Tano used the Force and held it , allowing CT - 7567 to rejoin Kenobi and Skywalker . Aftermath . The group soon departed back into the " Twilight " , although Skywalker saw that Tano was missing . The Togruta padawan was left onboard the freighter , however , it was part of her plan of tricking the Zygerrians . A slaver told Onyx about the injured Tano and soon they brought her to the cockpit of the ship . Meanwhile , Kenobi and Skywalker couldn ' t release the " Twilight " from the Zygerrian freighter which concerned the two Jedi . They then received a comlink transmission from Tano , who was held inside the cockpit of the slave ship . Skywalker told her to unlock their rear airlock doors to allow them to enter it . She acknowledged and used the Force to open the doors , while not alerting Onyx and his slavers in the cockpit . Using pressurized space suits , Skywalker , Kenobi and a group of clones left the " Twilight " to rescue Tano . After a minor attack by a Blixus , Skywalker and Kenobi ambushed the cockpit of the freighter and killed all but Onyz , who held Tano by the neck and pointed a blaster at her head . Kenobi calmed the Zygerrian down by stating they did not wish to fight , but instead know the location of the missing Kiros Togruta population . After Onyz revealed that the Togruta population was being traded inside the Zygerrian homeworld , and soon the Jedi and clones left in the " Twilight " .
