That was absolutely awesome. This story is really very well written. So much exposition, and it just all made perfect sense. And it was even somehow brought back far more in line with the original novel than I thought possible.

And I guess the '"Power the dark lord knows not" really is love, which is kinda awesome.

It's still kind of obvious how to defeat Voldemort though. Simply permanently disable him without killing him. Some magical prison, or a coma, or a permanent transfiguration into a stone. This is in fact so obvious that Voldemort himself should realize it as well. Maybe he just figures he is so far above Harry's power level that he has nothing to fear. Or he has some defenses against even this.

Another way to get rid of him: Destroy all his horcruxes on earth, then kill him. He'll live on on pioneer, but that's fine. You can pick him up again in 10000 years when humanity has progressed far beyond him, and can probably even cure him. Heck that'd even be a nice ending. A epilogue set 10,000 years from now, with Harry recovering the Pioneer 11 and curing Voldemort.

The sequel could then be a Harry / Voldemort slashfic where Harry and a redeemed Voldemort rule the galaxy as father and son.
