The doors of the great hall became draped in white satin as the Grand Sentinus had commanded. Today was a great day in the History of the Family. Today, Sentinus would replace Hans as Headmaster of Hogwarts - the first stepping stone to controlling the world. The doors opened. The students stood, soldier like. There were no longer tables in the great hall.
Sentinus entered, majestic, tall and proud. His blond hair few back - there was a crystal crown on his head which blasted out a beacon of light, blinding all who dared to look at the exquisite grace of the Grand. All his robes were white, flowing with the air itself. And as he walked, the floor worshipped his mastery.
He approached the staff table. And in a moment, the table melded together and formed a great black throne of ivory and coal. He sat on it, the white and black contorting to form a twisted supernatural presence.
"This is the day, I ascend to power," he told the school. "Let a new order rule over this ancient castle. Let us together purge this school to better ourselves as one establishment, one Family." And a tear came to his eye.
