So far this is a rather vague story tied to Harry Potter at best. You're turning Harry Potter into Voldemort for your story so far. I'm sorry but I'm not liking the story. You've got no characters that have hooked me into liking them. No clear good guys/bad guys and clearly nothing to make my interest linger. sorry. I'm not going to flame you on this but I've not found it interesting either. I wish you luck with it however and hope that you find the review to be something that you can use to more clearly define your characters.

This was the exact intention: in real life, there are no clear cut good guys and bad guys, so there aren't in this story either. Nor do people in real life have clearly defined characters: they are changing from one moment to the next, and constantly revealing parts of their character that surprise even themselves.
