Madoon was a soldier of the Galactic Republic stationed in the High Security Section of Belsavis Prison during the Galactic War. In 3641 BBY the Rattataki prisoners of the Blood of Talath tribe broke free during the riot and began ambushing prison guards, imitating bird voices for communication. Madoon was one of the guards that fell prey to such attack and failed to respond to a comm check from officer Serik.
