A Tactician was trained in both the theoretical and practical aspects of massed warfare, and had great knowledge of the works of the great military leaders of the Empire. The quintessential adherents of the Tactician trait were the students of the Lion Clan's Akodo War College. The teachings of the Akodo school were based on the writings of the Kami Akodo, who founded the Lion Clan at the dawn of the Empire. His treatise on tactics, called Leadership, formed the basis for the school's curriculum, although they also studied the works of the Empire's other great commanders throughout history, such as Sun Tao. ^{[citation needed]}
