Dal, a male Cathar, held the rank of Captain aboard the Daybreaker throughout the duration of the Cold War.
Back in 3643 BBY, while the medical frigate was being assaulted by an Imperial boarding party, a Jedi Knight made their way to the vessel. The Knight, along with Kira Carsen, boarded the ship to provide assistance to Dal, Doctor Senessa, and the other crew members in repelling the Imperial forces. After reaching the bridge, Dal and Senessa revealed that Darth Angral had merged the Planet Prison, Shock Drum, and Death Mark laser into a single weapon known as the Desolator, which he then used to obliterate the planet of Uphrades.
Senessa detected signs of life on the ravaged planet, indicating the presence of survivors in dire need of assistance and supplies. Dal, however, voiced his concerns, arguing that landing the Daybreaker on the planet would result in the ion field generated by the Planet Prison component of the Desolator frying the ship's engines, effectively trapping them there. Dal admitted that he had a family to think about and tried to dissuade the Knight from landing on the planet, offering the frigate's medical supplies as a bribe. However, the Knight instead alerted Senessa to Dal's betrayal. Disgusted, Dal abandoned ship in an escape pod, leaving Senessa to prepare for navigating the debris field and attempting a landing on the remains of Uphrades.
