Born and raised in Liverpool by a wealthy pureblood family, Rhea Bishop was raised to be the best of the best. The best social skills, the best grades, the most sophistication, whatever her parents asked of her. She was the perfect puppet - I mean, daughter. Her standing and raising hasn't affected her much (that she knows of and acknowledges); she's never noticed the benefits or disadvantages of being raised by a family of her standing. But now that she's attending Hogwarts, out of the grasps of her parents, things are bound to change.
As described by Kaegan Deathmote
Rhea is a kid who is honestly just a real sweetie but she has like this background presence of pureblood that makes you look twice.
She's the kind of friend you love to hang out with, but you wouldn't want to hang out with her friends.
