Harry Potter and the Goat Herd

Agatha is the only character we meet who's like I don't know man what if I lived a life without magic. She had a brother who disappeared under suspicious circumstances so they kind of had to keep her on campus and let her be the go herd but she's not trying to change or save the world. Davy thinks that Simon might be the greatest mage he certainly has the most magic of any person that anyone's ever met but of course he doesn't know what to do with it. He becomes obsessed with this prophecy of creating the greatest mages sort of uh bring balance to the force character or something.
