I can only teach things I know, and it's just normal high school things! English and math and geography- those sorts of things!

[ There is absolutely no way Astoria dragged her across universes to be a teacher? Looking at Arenvald, she believes most people here are older than her and don't need that extra schooling- it's not like they have exams to worry about here. Even people who've never gone to school before, why would they need to know Earth geography when this isn't any place on Earth that she knows?? ]
