Colonel Quaal Tavier Catharius was a formidable warrior and a charismatic leader who served as the thirty-first leader of the m'Yalfor'ac Order, his reign lasting over a dozen years during the Galactic Civil War. A Bitthævrian male from Guiteica, Tavier proved himself a keen soldier in battle against the Galactic Republic, and was eventually promoted to the leader of the m'Yalfor'ac Order and the Guiteica Militia—two organizations dedicated to maintaining strong military forces and protected Guiteica from outside invasion. He quickly became one of the most revered and successful Bitthævrian leaders, surviving many attempts at his ouster; he wore his numerous scars as signs of his bravery and worthiness in combat.
