Gaiden Shinji was the leader of the Order of Diagna. The Order of Diagna and the joint forces of Daggerfall and Sentinel attacked the Orc kingdom of Orsinium. The war is known as the Siege of Orsinium. It took thirty years for the joint armies to breach and destroy Orsinium. Gaiden Shinji was one of the casualties of the Siege of Orsinium. He was also the founder and original Blademaster of the Arena, which was completed shortly before the siege began.
