As you walk into the Charms classroom, the most noticeable difference is that all the desks have been pushed to the walls in a circular formation, leaving a wide, open area in the center of the classroom. In the back of the room, a large, white sheet is draped over--who knows what--, and whatever it is underneath shakes violently every few minutes. It's no wonder the desks have pushed far, far away from this object--whatever it may be.

Go ahead and take a seat. Professor Carlton, although not in the room right now, will be along shortly.
