"Welcome back to another term. The headmistress has given Professor Flitwick and me the opportunity to hold a dueling tournament for the students to showcase what they’ve retained. This tournament will run once a week for each year group. Each year group will square off against themselves; first within their respective Houses, then building up to inter-house face-offs, and sometimes along gender lines as well. Spells and charms are limited to non-lethal incantations and you are not allowed to cause serious injuries. Madam Pomfrey will be standing by to make sure no one is excessively hurt, as well as a couple of Aurors should anyone be so stupid as to try and kill a rival. This is a school, boys and girls, not a battlefield."
