Idk, Slytherin and Hufflepuff made one. I'm really bored so why not?
Helena Ravenclaw/The Grey Lady She admit that she ha rubato, stola her mother's diadom and where she hid it. She felt bad for telling Tom Riddle about it. But she told Harry which fixed a lot.
Filius Flitwick He's fair, nice, and a short little guy. In the battle of Hogwarts he didn't hesitate to help. He's the head of Ravenclaw for crying outloud!
Moaning Murtle OK, sure she's annoying. But she didn't have a very long life, o a happy life at that matter. She was crying and then the baslisk killed her. But even with all the sadness, she trusted...
