Either that or it could possibly be the Platinum Dragon Lord she might be fighting. Shalltear said something about taking down the unknown "nation" along with herself. What she would probably refer to may be the Agrande Republic since that nation have one of the Dragon Lords ruling over it and could be the person fighting Shalltear.
