Hey I’m Alastor Mad-Eye Moody Auror and member of the Order of the Phoenix and I’ll be your new Defence Against The Dark Arts teacher this year at Hogwarts pay attention because you’ll need to know what you’re up against and you’ll need to know how to defend yourself against the Dark Lord. There are 3 unforgivable curses the Cruciartus Curse, Imperio and Avader Kadavra. Use of either of these is one way ticket to Azkaban!
