Rio Sankt

Previously known as the leader of Aegrotan Special Organizations, he is one of the few immortalized by the Cometfall of the Pure Age. His involvement during the founding of ASO is greatly noted, as was his general success as the leader of ASO after the head founder's death. While Sankt was generally positively regarded both inside of the organization and out, there was much political friction between his brother, Jara Sankt, as well as one of his partners, Sean Truax. During the height of rising tension between the Celestinians and the Antheans, Rio Sankt was murdered by professor Jin Mancinelli.

Despite the aforementioned tension with his brother, Jara Sankt succeeded Rio as the leader of ASO.
