Karen sees through the ruse yet protects and nurtures Emma. After Catherine ruins herself with dark magic out of jealousy and allies with the dark wizard king for revenge, Emma grows strong, defends the manor alone, and gains the Goddess of Magic’s blessing. She marries Karen and becomes the respected lady of the north, while all villains face harsh justice.
