Basically it is about an OC modern assassin from the Brotherhood arriving to Hogwarts to help Harry Potter to locate a Horcux which may potentially a Piece of Eden. Well, this is my first fan fiction. The story came across my mind when I read some Assassin's Creed and Harry Potter crossover fictions. English is not my native language so there are probably a lot of errors and grammar mistakes (as my lecturer always comments on my writing assignment about I should look for help to improve my English). Do correct me if you found anything wrong. I really appreciate that.

I'm a fan more toward Assassin's Creed than Harry Potter, so the story will have more emphasis on the assassin rather than HP characters. I'm trying to read all the HP books again as the story mainly occurs in Hogwarts and the wizard world, there will be familiar AC places and characters but it will take quite a few chapters to reach that point. No Yaoi, No Slash. So hope you enjoy reading it

Chapter 1: First Encounter

Harry, Ron and Hermione saw this scene when they were walking along a dark alley in Diagon Alley: A hooded figure holding up a man against the wall, ready to punch the guy on the face. It seemed the guy was already beaten badly, proven by the swollen cheek of his. The poor guy struggled in vain and discovered the presence of Harry and his friends.

"Help….Help me! Please!", he attempted to seek help in fear.

"Hey, tough guy! Leave him alone!", Ron stepped in.

The hooded man slightly turned his head to the group, staring at the interrupters. Although half of his face covered under the hood, Harry saw the striking golden orbs of the owner. The eyes of a predator. The feeling sent a shiver down to Harry's spine.

"Trying to be a hero, I see. Why don't you try and make me, then?", the hooded man said with a smirk. The voice is deep and cold, yet, young. It seems his age is likely to be just as same as them.

"You bloodly…..!", provoked by his taunt, Ron was ready to raise his wand to teach this guy a lesson. It was Hermione who stop him from being reckless.

"Stop it! We don't want to a make a scene here. Let the guy go." She turned and threw a warning look to the hooded man.

The hooded man stared for a while, and then he discovered something on Harry's forehead.

"The lady has a point", he nodded. He turns to his victim and hissed under his tongue, "You are lucky I didn't break your jaw, bastard!" He released his grip and the other guy ran in terror.

His action surprised the three; he actually gave up so easily without a fight? The hooded man simply shrugged to their reaction and walked away like nothing had happened.

"What the HELL is wrong with that guy?" was Ron's conclusion. Harry nodded to agree.

"Come on, let's go. We still have to meet Dumbledore. Let's not keep him waiting."

End of Chapter 1.

So this is the first chapter. Harry first encounter with the mysterious hooded man which seems like a bully and enjoys picking on poor, random citizen (just like when you play the game. Don't lie, I know you do that all the time!) . There is a reason for him to do so but that will be explained later on the story. Our next chapter will introduce our OC assassin friend to Harry and his friend. I'll try not to OOC but sometimes it is hard to interpret how the character will react.
