Coldstone waved his wand and the Great Hall became empty apart from a dueling platform in the centre. Students were already in groups around the hall, waiting for his arrival. It was to be the first ever Dueling Lesson, and who better to teach it than the legendary Coldstone Harshing.

He stepped up onto the platform. The hall fell silent.

"Welcome Hogwarts, to your first ever Duelling session." Someone was talking, he waved his wand and the student was flung out of the room by magic. He coughed and waited for order.
