I have just recieved a letter from my father:
Dear Alaya,
I have been given orders to instruct you to collect followers of our Lord within the very walls of Hogwarts, to compensate for the foolish mistake of your brother. He feels that those still in school will be one of the greatest threats to Dumbledore. As I am currently preoccupied with your mother's failing health, I think it best that you come up with a plan amongst yourselves. Just something to remind them that their end is coming. Send a letter after you have called a meeting and tell me what it is that you plan to do. I request that you all meet me in the dungeons after dinner tomorrow night. Come in groups of twos or threes, to avoid looking suspicious.
Private to Bellatrix: Would you mind conducting the meeting for me? I would prefer not
to have to get my hands too dirty to have to speak in front of a group of people.
