Thank you!

I totally agree!

Thank you very much!  What do you want to know about the horcruxes...maybe I could tell you if you really want to know.  As for the history of dark wizards, yes, Voldie is dead, but unfortunately there will always be dark and dangerous wizards.  There was Grindelwald (sp?) before Voldemort, probably someone else before him.  I think the books say that Voldemort was the most powerful dark wizard in a century...but that implies that there have been other powerful wizards too.  SC isn't going to become a procession of one great dark lord after another, lol...I'd much rather concentrate  on the emotional aspects than an action-based story, but there are still some rather powerful DEs out there and in the sequel, probably some of the ones from Azkaban are going to escape, be released, etc.

But as for Harry thinking about needing to know the history, it's more because at this point, he's thinking he might become an Auror and he was just trying to decide which courses would be useful to him.  He was kind of idly thinking that if he knew more about how other dark wizards were defeated, it might come in handy at some point.

Thanks again!
