 just a curious little technicality!) for any form of magic would be so much that every Wizard in the ministry could band together and die from magical exhaustion before the system was set up. So what they did, the cheeky little buggers, is discretely set up wards over the house and neighbourhood of every magical muggleborn away at Hogwarts in first year. After all, I could practice my spells before boarding the train, couldn't I? The result is that anyone who doesn't know better tries magic and gets a warning that flies to their exact location to shout at them for the exact charm they did, putting the fear of god into whatever little sprog thought they were better than the almighty Ministry. The problem with this system is that anyone with any modicum of common sense and a little bit of smarts (me) will figure this out and promptly circumvent it. As Harry is registered as having a muggle residence he will have had those wards placed over his home, not to mention whatever unholy monstrosity Dumbledore cooked up to keep Tom out. This is why I started a few days in advance. Now, I live and die by Hogwarts: A History but whoever wrote that apparition was blocked should be put to death because that simply isn't the case. When apparition is done the common brute force way the wizard or witch doing it pops out a bit at a time rather than instantaneously, it happens in less than a femtosecond but for that time they are shattering the sound barrier, much like a whip does, hence the crack. Hogwarts blocks this displacement completely meaning they don't block the magic just the method. The problem with this is that my form doesn't do this, thanks to my buddy quantum physics and a bunch of confusing equations relating to black holes I technically appear at my destination before I apparated. I could spend hours explaining why that happens but to dumb it down I appear in my destination microseconds before I apparated and for a brief moment there are two Hemiones as we swap out and my double returns to the quantum realm. It's all very confusing but the gist is that I don't appear with a mighty crack, more of a gentle pop as my entire body appears instantly rather than becoming a whip for an insanely small amount of time. Anyways enough of my science rambling. I apparated to Dursleys and got to scouting work.
