Naughlen was a male Human commander of the Galactic Republic during the time of the Cold War. In 3643 BBY he was stationed on Nar Shaddaa and together with lieutenant Weggland was defending Republic Post Shylon from an Imperial attack led by General Kligton when the apprentice of Darth Baras arrived on the scene. The apprentice was systematically dismantling the power base of Sith Lord Rathari whom Kligton answered to and attacked his men when the General refused to switch sides. Weggland and Naughlen were amazed when a Sith killed fellow Imperials and even more when the Sith spared them in exchange for servitude. Puzzled, both men acknowledged that they had a debt to repay and later came to apprentice's aid in the showdown with Lord Rathari.
