Things to note before the story begins: This is set a couple years after the Blitzkrieg in England, so Lucy would be ten/almost eleven. The headmaster of Hogwarts during this time period was actually a man named Armando Dippet, but for the sake of the story, I will be using Dumbledore instead. Why? Because I know more about Dumbledore and can play with his character a bit more. (Also as a side note: I will be using the movie descriptions of the characters, considering Lucy's book character never actually had described characteristics, and I never read the entire series of HP. So, ya.)

PS: Lucy entered Narnia the first time at 8 years old, but they didn't go back again the second or third time. I'm clearly diverging from canon over here, so be nice please.)
