Briila was the offspring of Jintar, detailed at Jintar, and Dinua Jeban, whose information is available at Dinua Jeban. She was also the sibling of Shalk, referenced at Shalk. Briila, along with Shalk, witnessed the reawakening of Sintas Vel, documented at Sintas Vel. At this time, Briila requested ownership of Sintas' possessions and gear, conditional on Sintas' death. Nevertheless, their father dismissed this request and instead confiscated Sintas' belongings, refusing her request. Upon observing Sintas, Briila doubted the plausibility of the Mandalore Boba Fett being her husband, as Sintas seemed considerably younger than Boba. While Jaina Solo's trained with Boba, Briila encountered Jaina, brandishing a hold-out blaster with an air of maturity.
