Dabrin, a male admiral of the Republic Navy and a Human, served during the Cold War and the Galactic War against the Sith Empire. He commanded the Valor-class cruiser called the Valiant. Due to his vast understanding of the Republic Military, the Dark Jedi Warren Sedoru made him a target, seizing the Valiant, capturing Dabrin, and questioning him to get Republic fleet codes. The Jedi Knight known as the Hero of Tython rescued Dabrin by defeating Sedoru. Dabrin wanted Sedoru to be executed before he could leak the codes to the Empire, but the Jedi refused, believing Sedoru could be redeemed. As Sedoru taunted the Hero for their compassion, Dabrin knocked him unconscious, promising to keep him sedated until the Jedi returned to take him.
Following the Hero's victory over the Sith Emperor, Dabrin himself presented the Hero and their companions with the Cross of Glory as a reward.
