German soldier Gustav Brandt served with the French forces during the Vietnam War. While in Saigon, he met and fell in love with a Vietnamese woman named Lua, and eventually had a daughter with her. However, Lua's brother Khruul was enraged with the interracial coupling of his sister and a European man. He and his men attacked Gustav and his family with flamethrowers. Lua was killed in the ensuing battle, and Gustav lost his eyesight. He and his daughter took shelter in Pama, where he was trained by the priests, but was forbidden to communicate with his daughter. Joining the Zodiac Cartel, Gustav adopted the codename Libra, and served as a terrorist.
