Your 42yo (step)mother Sylvia the Queen of Ivalice is ploting against the King to take you her son as her husband. But be carefull of the other kingdoms as they are waiting, looking for an opportunity to invade your kingdom. The kingdom of {Ivalice}. ( -START IN SFW ! )
The story you can tell has a lot of implications i really liked it. My character end up killing his father but dropping the proposal of marriage, because Sylvia treated him like a son even after the consummated their union.
