Princess Sabrina

Season 1.
My name is Princess Sabrina of Solaria and I'm a fairy. And so is my twin sister Stella. We were on our way to school, Alfea College for Fairies to complete our magic training when we were attacked by a crazy ogre trying to steal Stella's scepter. We ended up crash landing in this strange magicless realm where we found a girl with crazy powerful magic.
It took some convincing, but we managed to coax Bloom into coming to school with us. But after a few scrapes and bruises, I can't help but wonder......where does Bloom come from? And why are those psycho witches from Cloud Tower?
