Venku is the brother of Verd'rik Sondar and is part of an elite fighting unit known as the Mandalorian Executioners. The Executioners are known for fighting very dirty in combat, even using berserker tactics. Venku and a fellow Mandalorian Executioner named Darman Viulf have formed a romantic relationship during the Yuuzhan Vong invasion of known space. The two men fought side by side when the Vong attacked the planet of Mandalore and both of them received Jag Eyes on their helmets as a sign of valor after the conflict ended.
