Sergiad

Duke Sergead (High Lord Sergiatte Cowen in the anime) is the head of clan Corwen, ruler of Maihama, and the chairperson of the League of Freedom Cities Eastal.

Personality
Outwardly, he has a commanding presence and is treated with the utmost respect by his fellow nobles. Inwardly, he is open-minded and sees the Adventurers more as equals rather than as potential members of the League. He later decides not offer them membership and instead signs a treaty with them.
