it's not supposed to be based one-on-one on hp fandom and hp bnfs - it's parodying some stuff from other fandoms and kind of making stuff up, too. i think one of two of the characters who are supposed to be the cassie's right-hand-dudes is based partly on heidi, at least. but really, you are bound to have more first-hand knowledge of the people involved than the role-players will!
