Serrena operated out of an abandoned building of the Brushlands of E'ronoh with her partner, fellow Kage and Path member Abda. Though she had failed, Serrena later intercepted an EX droid containing a message of two Jedi Masters, so she informed the Mother that the Jedi had arrived in the system.
Later, Serrena confronted Queen Adrialla of Eiram aboard the Galactic Republic Longbeam cruiser Paxion, where a peace summit was being held to end the war, confronting her about her breaking her deal with the Mother to manufacture poison for them. Adrialla refused to start up production again, and Serrena was shot with a blaster by Adrialla's wife, Odelia, but escaped in an escape pod and returned back to Abda. Angry at her for failing, and being emboldened by being chosen by the Mother to be one of her Children, Abda secretly put the same poison in Serrena's blaster wound while treating it, killing her.
