More over-the-top dramatic than I'd write, but that's fine.
This got rated down for being a Mary Sue, which seems unfair at this point. It's just at its beginning, so far as I can tell, we don't know anything about the main character, and the (maybe, I'm guessing) supposedly Mary-Sueish name was one that Voldemort made up. If the message is that only Voldemort would name a kid something like that, I hardly think that fits into the traditional Mary Sue mold.
