Claudin Asgard (クローディン・アスガード Kuroodin Asugaado?) is known to have been one of the earliest Shepherds, as well as an exorcist, who used his powers to end the Era of Darkness, unite the central continent to form the Holy Midgand Empire, and usher in the Era of Asgard. Claudin was the mentor of Artorius Collbrande, the primary antagonist of Tales of Berseria.
