Muggle Studies

You play as Alice Armstrong, the new Professor of Muggle Studies at Hogwarts School of Witchcraft and Wizardry in Scotland, even though you've never heard of "muggles" before and never knew magic was real until the headmaster proved it to you. But when you arrive at the school, you discover that a botched spell has made everyone disappear and you're now trapped within the castle. Is this something you can fix without magic?
