Juul, a Human woman from Coruscant, was the sister of Jiik. Back in 3643 BBY, after the Justicars' Brigade took her brother into custody, Juul found herself in need of assistance from the Voidhound to secure his release. Her gender is female.
Living on the planet of Coruscant, the capital world of the Republic, Juul resided with her brother Jiik during the year 3643 BBY. Both siblings worked as informants, providing information to Darmas Pollaran's network. While shadowing the infamous criminal Skavak on Pollaran's behalf, they inadvertently trespassed into the territory controlled by the Justicars' Brigade, forcing them to split up to avoid capture. Jiik continued his pursuit of Skavak, witnessing him enter the Works, but was subsequently imprisoned by the Justicars. after she witnessed them meet with their backers in the reconstituted Sith Empire.
Juul then met up with Corso Riggs and a smuggler captain who Pollaran had hired to help track down Skavak. Angrily, she confronted the smuggler, placing the blame for her brother's predicament on them, and insisted that they would need to rescue Jiik from the Justicars' Tower if they wanted to discover Skavak's whereabouts. Juul cautioned the pair that they would have to disable the security cameras, which she called "droid-eyes," to prevent the Justicars from identifying them or her brother. She also demanded that they take a holocommunicator so she could communicate with Jiik once he was freed.
After the outlaws successfully freed Jiik, the siblings conversed via Juul's holocommunicator. Jiik relayed information about the Justicars' dealings with the Sith and Skavak's destination. Juul suggested he hide from the Justicars by crawling through a tunnel they had previously discovered, leading to a warehouse where she could conceal him. She asked him to take the holocommunicator from the captain so she could watch him as he crawled through the tunnel.
Her experiences in the rougher parts of Coruscant, which she referred to as 'turfer land', led Juul to adopt a stern personality. When the Justicars captured her brother, she held the future Voidhound and Corso Riggs responsible, as they were the reason the siblings were tracking Skavak, but she also showed deep concern for Jiik. She insisted the Voidhound bring a holocommunicator so she could speak with Jiik immediately after his release, and she wanted him to take it with him as he crawled through the tunnels, concerned for his well-being.
Juul understood that Corso and the smuggler needed to disable the Justicars' security cameras to avoid identification, but she showed a lack of technological understanding by calling them "droid-eyes". She also expressed negativity and disdain towards the two outlaws, calling them "cloudheads" and implying that they were not accustomed to the harsher areas of Coruscant.
Juul had brown hair, blue eyes, and tan skin. She and her brother were skilled trackers, demonstrated by her ability to lead the Justicars away from Jiik while avoiding capture herself.
