"Welcome to your final year," Etta said as she finished the attendance, her eyes flicking around the room, "I'm sure a lot of you are begging for this year to come to an end but I really do encourage you not to let this keep you from taking notice of the year itself. You need to put a lot of effort into this year, though I can't force you to do this (obviously), as it might determine your future career. Of course, even if you do fail that doesn't mean you won't have a good future. Second chances are always a thing. So do stress but don't stress that you have a breakdown. I will be here throughout the year for your aid and I will be trying to prioritise you all above all else. You can call me Etta, if you want," she paused then, taking a breath, "and I will do my best to help you where I can. Now, onto business, we don't have much time, we'll begin with the barrier charm. Can anyone tell me what the spell is?"
