Aventius is too stubborn, but what about his guards, are they really that stubborn as well... their kingdom will die if they act, so surrender to us and their will be mercy...
Actually, my kingdom will not die. I have an heir, he may too young to rule the throne but queen Elena will rule until he comes of age... And I made a new post. Though I'm sure most of those soldiers may just let Fadril take Aventius away for fear of having him killed. (Not the risk of destroying the kingdom.)
