Arla Fett Arla Fett was the older sister of the bounty hunter and Mandalore Jango Fett , and the only daughter of their Journeyman Protector father . She was also the long - lost " aunt " of Boba Fett . Biography . Born on the planet of Concord Dawn , Arla spent her youth living on the Fett homestead with her parents and brother , Jango . In 58 BBY , when she was 14 , the Mandalorian Civil War — fought between the True Mandalorians , under Jaster Mereel , and the splinter group known as the Death Watch , under Tor Vizsla — spread to Concord Dawn . When the Death Watch began hunting down members of the True Mandalorians that escaped from a lost battle , Arla ' s father offered Mereel and his men refuge on their farm . The Death Watch tracked them to the homestead and killed her father as her brother Jango was fleeing . When they turned their attention on Jango , Arla witnessed their mother shoot and kill one of the Death Watch members with a blaster rifle , only to be killed herself . While Jango fled and would be later be rescued by the Mandalorians , Vizsla ordered there be no witnesses and Arla was to be " taken care of " . Thus , Arla was believed to have been killed on Concord Dawn along with her parents . Seemingly unknown to anyone else , was the fact that she was spared by the members of the Death Watch , and was held hostage by them . They viewed her as a prize , and branded their logo onto her back . After a while as their prisoner , Arla joined the Death Watch cause as an assassin , and only left them when she got arrested for a shooting 10 years before the end of the Clone Wars . While in custody , Arla was deemed mentally unstable and was ordered to be held in the Valorum Center — a mental institution on Coruscant — for many years . In 19 BBY , three years after Jango ' s death on at the Battle of Geonosis , the former Jedi - turned - Mandalorian , Bardan Jusik , visited the center looking for Separatist scientist , Dr . Ovolot Qail Uthan . At the time of his first visit , Jusik had walked passed Arla ' s cell , hearing words that resembled the Mandalorian language . Later , during the Separatist invasion of Coruscant , Kal Skirata and Jusik returned to the center to free Uthan from her cell and upon doing so , Bardan again heard words that resembled Mando ' a . The ex - Jedi acted on impulse and decided to free the prisoner , and when the group was picked up by Walon Vau afterward by a LAAT / i gunship , Jusik revealed her to be Arla Fett , Jango ' s lost and supposedly dead sister . Arla would go to Mandalore along with Jusik and the rest of the Skirata ' s rogue band when they fled Coruscant following the issue of Order 66 , taking up residence in an old storage room at their bastion home of Kyrimorut . At Kyrimorut , attempts were made to regulate Arla ' s medication from the regimen given at Valorum Center , but the dosages were insufficient and Arla attacked Jusik without any provocation . After hearing Arla ' s story and her insistence that she forget everything , Jusik offered to use the Force to wipe her memory of the traumatic events in exchange for intel on the Death Watch . Personality and traits . Arla Fett , after her capture by the Death Watch , was resentful of her captors , but grew to care for them . Instead of attempting to escape them , she joined their cause as an assassin . Through Death Watch intel , she found out that her younger brother Jango had survived , but made no move to reunite with him . During her arrest and incarceration at the Valorum Center , she was heavily sedated in an effort to prevent her from killing herself over the guilt she felt in her willing participation in a group that killed her family . After she was rescued by Bardan Jusik and brought back to Mandalore , her medication was changed , and while she was more lucid , her memories and the guilt came flooding back , and she ended up launching an unprovoked attack at Jusik while wandering around the compound . Later on , in a moment of clarity , Arla begged Jusik to kill her in an attempt to put her out of her misery , but he refused . Instead , the pair agreed to a compromise that involved Jusik erasing her memories in exchange for intel on the Death Watch . Arla spoke the language of Concord Dawn , which is similar to Mando ' a . By her own admission , Arla was a " good shot " with a blaster , which helped her in her career as a Death Watch assassin . Behind the scenes .
