Filtered Network Post: Minerva McGonagall to Magic Folk [FILTERED TO WIZARDING WORLD AND ALL OTHER MAGICAL PEOPLE]
Last month, people were compelled to voice the truth and their every thought. We have just seen people reversed in time.
I would hope that no one intended such widespread results, but nevertheless, I believe we need to have an open, frank discussion about how we're using our magic given the extreme side effects we have seen, and about communicating when the unexpected happens so that we might help to correct it.
For instance, I am creating wizarding chess sets for use here. If anyone should feel a compulsion to move to E5 or capture a pawn, I expect to be informed promptly so I can cast the relevant counter-charms.
