There standing at the end of the corridor, flanked by teachers and students alike, stood a figure blazing with so much power that it was blinding to look directly at him. As he drew nearer and looked each student in the eye they flinched from the coldness directed toward them, usually reserved for those he hated.
Arriving at the middle of the corridor he waved his hand and a black sign appeared above each person's head. In a deceptively calm voice that was only belied by the fury on his face he explained the situation.
"In all my years of teaching here I have never seen students act the way any of you have acted tonight. Even those who had no part in the actual fight contributed, you stood around watching passively and did not intervene, even when it was clear that Harry was injured very badly and needed medical attention. This is a time of war, with the battle to determine the fate of the world raging right outside our doorsteps and you choose now to have this cowardly fight; this fight where one person gets brutally attacked by not just one person, but five different people, of whom he had once called friends."
Glancing at each student he noted the guilt on the faces, "Good at least they can still show some remorse for what they did," he thought to himself. Turning around to face everyone, he was a formidable sight with the ice in his blue eyes and fury directed at each one of them. He continued this time to explain the marks.
"Now I'm sure your all wondering what that black mark that I've placed above your heads is, well, first and foremost it is to isolate each and everyone of you from the rest of your peers, in other words you will not be able to communicate with anyone other than myself or the other professors. Second it is part of you punishment as it inflicts some form of physical, emotional and mental pain for the amount of suffering that you have caused Harry. Lastly, it subjects you to the ridicule you are sure to be facing for the rest of your time here at Hogwarts. However that is not your only punishment, for the rest of your time here you are at the beck and call of each and every whim of me, the professors, the caretaker, the Head Boy and Girl, as well as the prefects. None of you will be able to remain as prefects or to ever obtain the position of a prefect or a Head Boy or Girl; also you will not be able to gain any points for your house, only lose them; finally your last bit of punishment will be a particular bit of magic placed on all your clothing which identifies you as the type of person who would do such a thing."
He gave them a sneer and stalked off towards the Hospital Wing, where Harry had been immediately sent after discovery of his wounds, leaving the professors to lead all the students back to their respective dormitories and lock them in, so they could go to the Hospital Wing to see if they may be of any assistance.
At the Hospital Wing Madam Pomphrey was bustling around and giving orders to the professors to bring particular charms, potions, or a bit of magic meant for healing. All the professors looked on worriedly not just because he was the Savior of the World but rather a boy they had gotten to know rather well in the times of preparation to fulfill his destiny.
Finally about three hours later she stopped and exclaimed, "I've done all I can do, seeing as his condition is now stable, even though he is still unconscious and has fallen into a coma, it seems as though his magic is healing him so there is nothing else we can do except to wait."
She collapsed on a chair that Dumbledore conjured up for her, anticipating her weakened state; he addressed the faculty with his calm demeanor restored and his fury contained once again.
"You all heard what the woman said, there is no use for us to stay here, and so we might as well go back to our quarters and drop by once in a while to see how things are going so we do not overcrowd the Wing. Also I am giving you permission to devise whatever punishment you choose to administer to those who have contributed to this incident, we shall all contribute to the punishment for the worst offenders."
The professors glanced at each other and then at Dumbledore before they grinned at each other wickedly, as they devised the worst possible punishments that came across their mind; as if on cue everyone glanced at Professor Snape, who grinned evilly at the thought of being given free reign to punish the Gryffindors as he wished for so many times.
The gaggle of professors all trooped to one of the interior workshops after Dumbledore had given the command to lock down the entire castle, though food would still be served by the house elves at the appropriate times direct to the Common Room; as well as regular assignments from the different teachers.
After about a week of so had passed they had devised a list of the most horrible, embarrassing, and peculiar punishments they could possibly devise for the students involved they rested as they could hardly wait for the next time they saw the students.
They needed to be able to do something to help the boy who had done so much for them and the world no matter how oblivious it was to have taken advantage of the boy like so.
