Prologue
Rose Weasley felt the spell coming before she saw it and spun around. Mandy Crabbe, the slytherin princess, was standing there pointing her wand straight at Rose.
"Look Crabbe, it's the first day of term just leave me alone." Said Rose, exasperated already.
"I don't think so Weasley," replied Crabbe, smirking as she threw an expelliarmus at Rose, who deflected it easily. "You better watch yourself this year, things are changing around here."
As she walked away Rose sighed and continued on her way up to the common room. It was the first day of her seventh year and she had already had a less than pleasant encounter with a Slytherin, the rivalry between them was ridiculous. You would think that since the war things at Hogwarts had changed for the better but it seemed that no one could get over the millennia old rivalry between the houses. If you were a Gryffindor then you automatically hated all Slytherins and vice versa, otherwise you were labelled a freak. The only people that seemed to get around this unwritten rule were Albus Potter and Scorpius Malfoy, who had early on become fast friends and due to their parents status and their personalities were extremely popular.
As Rose climbed in the portrait hole she saw her best friend Mary Longbottom sitting in front of the fire reading a book. "I'm so excited to be sitting here, finally we get the best seats in front of the fire! It's about the only good thing about being in seventh year though… What's wrong?" Mary asked as she finished her rant.
"Nah, I'm fine I just ran into Crabbe down in the dungeons." Rose replied, while deep in thought.
"Those slimy Slytherins," Mary grumbled under her breath "don't let it bother you though Ro"
"It's not but I think I have an idea," said Rose slowly. She loved her family but she always felt somewhat overshadowed by them. Having a family like she did this was understandable, both parents were prominent war heroes and she had so many cousins it was hard to count. She didn't want to be just another red head anymore she wanted to be Rose Weasley. "I'm going to get rid of the rivalry between Gryffindor and Slytherin."
"I'm sorry Ro, are you sure Crabbe didn't hex you?"
"Yes Mary! Come on, look what our parents did at our age, I want to do something, to be remembered for something." Rose said.
"Look Ro, I get you, I really do but how are you going to do that? Seriously the Slytherins and Gryffindors hate each other." Mary said.
"But Al and Scorpius are friends! If a Potter and a Malfoy can do it then I'm sure everyone else can. How hard can it be?" Rose said to a sceptical Mary. "I've got it all planned, I was thinking about it on the way here through patrols. So I'll go to McGonagall and ask for her help, she should listen to me, I'm head girl after all."
"I guess you've got a point"
"I'm going to do it! I am."
"Hey Ro, one question, can we call it Operation Slythendor?"
Laughing, Rose said "If you're going to help me then we can call it anything you like."
