Sergeant Marshall,
I was told by an officer, I believe it was Lockwood, that Aseir Greycastle was the one leading the group of volunteers. I think this is probably right, because I received a letter from him that indicated he would be gone shortly before this all happened.
As far as the council notifying you: As far as I know, the Watch was made aware of things as quickly as we were. The problem here wasn't the council withholding information, but not having it.

Thanks Salina, for all your hard work.
