"Please, ladies and gentlemen, just a few minutes more.  This being a masquerade does mean you are strongly encouraged to wear a mask, and you are welcome to disguise yourselves in any manner you choose.  Portkeys will be provided to each attendee to the Great Hall on the night in question.  Miss Brown will be heading the team to organize and design the event.  Please see her or myself if you have any questions.  Enjoy your evening."  She nodded to the student body before stepping away from the podium.
