Okay I've got two children with magical ability. They've been raised since babyhood by their grandmother, who killed their parents (because they were on the council that bound her powers, she's quite a monstrous person) and raised them as tools to attain power, not showing them any love and affection. She forced them to do everything with magic, and her own wild ideas of magical training has left them unable to completely control their powes. They have never ventured beyond her estate which is hidden from the outside world, they have never interacted with other children. One day they kill her in self defense, venture beyond her estate. They get put into foster care and have to be part of normal society for the first time. So likely psychological effects that their upbrining might have on the two?
