What does it mean? That was an excellent question. I had no doubt in my mind that Tobias was attacking London for some reason. Maybe a ritual of some kind? It had to have something to do with the Deathly Hallows. The clouds above and swirling deathly green energy was proof of that. It also meant that the Statute was currently in the process of being broken, but I didn’t really care about this. That led to one one conclusion.
