The Lost Maurader and New Identity

(Harry Potter Fanfic. Mauraders Era.)

Rome.
Rome Black.
That right. Sirius and Regulus Black's sister.
No, better than that.
Sirius Black's TWIN.
I know right!
Wait. You've never heard about The Lost Maurader, have you?
Well, here's an intro...

Rome Nikki Black was Sirius Orion Black's twin sister. No one really knew her. Except for Sirius, Regulus, and her parents, of course. In fact, no one knew there WAS a twin sister to Sirius. Her mother, Walburga Black, thought she was a pure blood maniac. Of course, Ms. Black didn't call use those exact words but.... It was how Rome was brought up. She thought that there shouldn't be stereotypes. She thought muggleborns should be given a CHANCE to prove themselves first. Anyway, as I was saying, she hated stereotypes. Everytime she met someone, everyone thought she was a snobby, stuck up, pureblood maniac. She was ashamed of her last name. So, aboard the Hogwarts Express, she wasn't going to be Rome Nikki Black. She was going to have a New identity. First she needed to talk to Dumbledore. And her family. They never knew her. At least, they pretended so. Walburga was NOT happy, but respected her favorite child's wishes. Rome Nikki Black is now Ariana Rome Dumbledore. And she's the Lost Maurader. However, I am going WAY too fast. I must start at the very beginning.
