The Clan of the Hidden Terror (Revised)

I wrote this story a long time ago, but I lost the my login information for the account, but the story is too good to waste. I want to do my best and finish it. There are a lot of words here that are directly from the Harry Potter series, so I can't credit them as my own. However, all of the extra original characters in this stories are characters in a novel that I am writing. Thx!
