In 35 ABY, Kallie Lintra participated in the battle against the Final Order, a fleet assembled by the Sith Eternal cult, on the planet Exegol in the Unknown Regions. Lintra piloted an RZ-2 A-wing interceptor during the battle and was part of the air strike team tasked with protecting the Resistance ground forces. Shortly before the arrival of the Citizens' Fleet, Lintra engaged eight TIE fighters that were surrounding her A-wing starfighter, managing to destroy three of them before she was killed. After witnessing Lintra's death, General Poe Dameron mourned the loss and recalled that they had lost both Kallie and her sister Tallie during the war against the First Order.
