Father Matthias
In the desolate immortal world, the church holds the second most influential position in terms of authority, after the Royal family. In certain scenarios, the church even surpasses the royal family in authority, wielding power that the royal family cannot disregard. However, this doesn't imply that the church's power is greater than the royal family's; rather, the church operates under the rule of the royal family. Regardless of the specific charge, the head of the church must be a member of the royal family.
