Doji Hatsuo was not only the Crane Clan Champion but friend and military advisor of the Emperor. In the year 150 he became the fifth Emerald Champion. Hatsuo was commanded to develop a consistent system of law enforcement within the Empire, and alongside his principal advisor, judge Soshi Saibankan, developed the framework for the Emerald Magistrates and the Imperial Legions. To this date, there had been no radical change in the system originally laid out by Hatsuo and Saibankan.
