Nice, I've been wanting to see some "Harry takes over to finish the job" type stories for years.
Stories where after defeating Voldemort, Harry winds up having to conqueror the magical world to end the bigotry. Even if that means becoming a dark lord in his own right. The only thing I've seen that comes close is "Burning Day" by Kinsfire.
Nice to see somebody else with the idea. I used to post about this mainly on CaerAzkaban.
