Quite the interesting introduction to what portends to be a fascinating story. I'll admit the title had me looking up some old Sergio Leone theme music though, given the situation, 'twould seem that perhaps "The Outlaw Harry Potter" might be a better title; but that's as may be. It's rather interesting that there are more factions out there than the three we normally think of/know about and that two of them are collaborating to help train Harry. I find it interesting that the party watching Hermione for Dumbles didn't realize the import of that telephone conversation and I'm looking forward to seeing how that comes back to bite some folks. I really don't think Dumbles realizes just how much ill will he's accumulated and I suspect it's going to drive him to distraction as he deals with the consequences this.
I'm very definitely looking forward to following chapters.
