Overall, an incredibly interesting story - you introduced your own new characters and societies well, and plausibly. I don't think I've ever seen anyone take the horcrux angle anywhere near the way you did, and you pulled it off incredibly well. Yes, the end was a bit off-balance, but by far it was an entirely enjoyable story.
I did notice a plotline (the Hallows) that kind of trailed off, though. I don't know if your direction in the story changed, or if you simply lost the thread of it in the overarching plot, but harry never did get the Elder wand or do anything with the Hallows, and although the Druids seem to have spread their religion fairly well in the end, there certainly wasn't anything remotely significant in Harry's part in it.
Anyway, other than that little issue (plothole?) its a great, incredibly novel story that completely sucked away my entire day. I'm looking forward to reading several of your other stories soon.
