One day, news arrived that the emperor of Saulverka, the mysterious empire to the north, was seeking a wife.

Even as she laments her own life, it is only after leaving her country that Amelia learns the truth of how her mother had been treated, and she burns with fury. To avenge her mother, she swears vengeance upon her homeland.
