Eithan Arelius first appears as a flamboyantly confident Underlord of the Arelius family, adopting Lindon and Yerin as disciples and personally guiding them through the Blackflame Trials. By the time of the Uncrowned King tournament, his role has expanded from local patriarch to international competitor, representing the Blackflame Empire alongside his students.
