Queen Valanice was proclaimed as a compassionate soul to just about everyone she met. Her loving heart relayed to her own daughter, and when she was sadly kidnapped, Valanice leaped into action to save her in King's Quest VII.
Being the protagonist of the seventh entry in the series, Valanice braves harsh climates and environments in order to be reunited with her daughter. A face of beauty couldn't quite cut it when going up against giant scorpions and other nasties, but Valanice's sheer love and desperation to see her daughter again won the day.
It's a clichéd term, but love does conquer all. In Valanice's case, it allowed her to courageously venture across dangerous lands for the sake of her child. Would your mother do that for you? You may be inclined to say no, but when push comes to shove, you'd be surprised at what a mother would be willing to do to keep their child out of harm's way.
