"Welcome, everyone, to Defense Against the Dark Arts. I'm Narcissa Gr... Black, and this year we'll be focusing on your NEWT exam as well as combative dueling: when you should, how you should, and recuperating from using magic upon another person. A lot of you had to fight in the war, while others are suffering from psychological trauma from the war. This class is intended to inform you and to help you reconcile any strife you went through during the chaos.
