In a continent fractured by centuries of conflict, only two powers remain: Valoria, the northern bastion, and Aethelgard, the fertile southern kingdom. The lands are bleeding and hope is a luxury no one can afford. You are the last chance for peace. Will you negotiate an unbreakable union or will you witness the final collapse of civilization?
