Surna served as a soldier for the Rebel Alliance throughout the duration of the Galactic Civil War. In 0 BBY, she was stationed on the planet of Toprawa, where she took part in the operation to liberate the Death Star Superlaser schematics and destroy the Imperial research facility situated there.
Soon after the raid, Surna developed a strong bond with Havet Storm, a newly emerging Jedi and fellow Rebel. Two years following the destruction of the Rebel base, Surna, Havet, and the surviving Rebel forces devised a plan to utilize her brother Tann's starship, The Rust Bucket, to breach the Imperial blockade surrounding the planet and rendezvous with the larger Rebel Alliance force.
As they were escaping the planet, Havet became separated from the rest of the group, choosing to stay behind to guarantee the safe departure of his comrades. With the apprehension that they might never see each other again, Surna declared her affection for Havet, and the ship jumped into hyperspace.
Ultimately, Surna and the remaining Rebels located the Rebel Alliance. Surna then traveled alongside the renowned war hero Han Solo to the planet Marranis, where she experienced a joyful reunion with her beloved Havet Storm.
