"I had made hand mirrors that allow visual communication between other hand mirrors. Made from a small muggle mirror, I made a network for my friends and I. What I would like is to give the Unspeakables the notes and make a single network for the Aurors. Of course, I have no problem if you wish to use the schematics for the Unspeakables." I fully expect them to use it themselves. How nice would it be to talk to one another through the mirror while working on projects?
