The Great Hall is empty, as there is no reason for anyone to be in the Hall at this time of day. The tables have been lined up in the center of the Hall, dividing it into two equal parts. Cluttered on every centimeter of available table surface, various dishes leftover from the past week's meals crowd together. From last night's pudding to a slightly odoriferous sauerkraut from lunch a week ago, the food is a vast variety of dishes in just as varied condition.
"We're going to have a food fight, but not exactly the fun sort that you may be used to. The point of this exercise is to keep yourself as clean as possible, using any of the spells we discussed as well as any spells you have learned during your career at Hogwarts. Within reason, of course... no theoretical spells you have never actually practiced and no spells that will purposefully cause harm to anyone else. I will remove you if you are hurting your peers. It is up to you whether you choose to play offensively or defensively... perhaps your best way to keep clean is to knock out the other players?"
He gestured into the room. "Please line up on either side of the table and we will begin at my mark."
ooc: As always, please do not RP the outcome of your casting/throwing. You are free to use any spell that there is a reasonable expectation your character knows, but we will definitely cry foul if you get way ooc. Please clearly indicate who you are aiming for.
