Generally I arbitrarily reject this type story. However it captured my interest in the first chapter and I can't wait for the nest. I am glad you stopped with the redundant telling of who all of the characters were as it seemed to take a quarter or more of a chapter length to do so. However, when a new character is introduced an explanation of who and what they are seems to be very appropriate to me, but you're the author not me.
Please keep up the great work on this story. I'm not a Dumbydore fan even in the cannon and never trusted the Weasleys that much either. There is much about the canon that defies logic some of which you point out. I appreciate the effort it takes to write such a story haven written four Interface Manuals and writing as well as teaching the Disc Drive Training program for Seagate in the late 80’s through 2004.
Looking forward to your next chapter.
