Izzy was on edge.  Hoping that the boys picked up on the fact that she wanted to help them, she gave them all the information they needed.  She didn't know how to help them escape thought, and she certainly didn't know what to do with the matrons.  She hadn't planned for them to be there, and she already said she'd kill them.  She hoped some of them could do wandless magic...

"But enough talking!  I've got Death Eaters stationed throughout the Castle, already rounding up students.  This school is going into full lock down.  No one in or out.  Nothing enters or leaves," Izzy continued.

"Why?  What do you need Hogwarts for?" Draco asked.  Izzy watched as realization dawned on him.  "No... you aren't going to..."

"That's right.  Ethnic cleansing, Dark Lord style.  Every muggleborn in the place will be slaughtered.  Every half-blood with more muggle blood than magic blood will be slaughtered.  And you three will be the demonstration sacrifices.  Choosing to oppose the Dark Lord gets you killed," she said with fake maliciousness.

Izzy cast Incarcerous on the Matrons and the boys and dragged them all along behind her with the ropes.  She found a couple Death Eaters in the corridor and asked them to help her escort their prisoners to the Great Hall.

When they got there, she noticed that every student was seated at their respective tables.  By now it was about seven in the morning, and so everyone looked sleepy and like they were expecting breakfast.  Except no breakfast came.

"Students!" Izzy called, magnifying her voice when she got to the front of the hall.  "I've got a special announcement to make."

Murmurs could be heard throughout the hall wondering about the whereabouts of breakfast and why Harry, Ron and Draco and Madam Pomfrey and McGonagall were tied up.  Izzy hated doing this.  She'd never be able to go back from it now.  She was in too deep.

Suddenly a tall man with long, sleek blond hair entered the hall.  Lucius Malfoy.  How the Carrows managed to get him out of his Manor (he was on house arrest due to his pending trial) was a surprise to me, but it happened.  He walked all the way up to me, trailed closely by the Carrows and Antonin Dolohov.  All four of them had survived the Battle of Hogwarts, as had Augustus Rookwood, Walden Macnair, and many other Death Eaters.

Izzy heard the gasps of students and the murmurs before Lucius reached her.  She let him walk up to her and speak to her, although she was disgusted by his very existence.

"What do you want, Lucius?"

"I would rather you regard me as Mr. Malfoy, scum.  However, I would like to tell you that the school has been scoured and not a single child isn't in this room right now.  I have Death Eaters stationed at every exit.  The lock down has been initiated."

"Ah."  Izzy exhaled, disappointed that it had worked, but she tried not to show it.  "Good.  Now get out of my sight.  As I recall, you are the betraying scum, seeing as how I am the Dark Lord's right hand man."

Lucius spat at my feet, which was insulting as I was at least a foot smaller than him.  He turned and walked behind me a few feet as the Carrows walked to the Great Hall doors to guard them.

"I'm sure you're all wondering why you're here," I began, deciding to put it bluntly.  "It's quite simple, really.  See, Lord Voldemort has returned and is working with the Ministry of Magic to complete a mass Blood Status-based genocide."
