Mana at Hogwarts (temporary title)

Welcome to this story, it's one of those "Harry Potter" fanfictions, a Self-insert (kind of, OC-SI) at that. I know most people will give this story a skip, but for those of you who read it, thanks for your time, sorry if I wasted it, if you want more chapters of Selfinsert Raven, don't worry, they WILL come, but I'm not a very good author, and therefore can't think of how to write the next chapter yet.

Chrissy was stolen from our world and placed into a parallel Harry Potter world, meaning we don't have the exact canon universe Miss Rowling wrote. Chrissy also knows the one true law of magic: Magic has no rules. So, beware madness ahead.

Anyway, here's the story of Christina Demi Arc.

.ılılıll|̲̅̅●̲̅̅|̲̅̅=̲̅̅|̲̅̅●̲̅̅|llılılı.

Chapter one: Introduction of the Protagonist

The date is 1991, 4th of July; and I walk down the stairs at the leaky cauldron and wave at the owner Tom.

"Hello Miss Arc, what would you like?"
"Entrance to Diagon Alley please" Tom leads me to the entrance, and lets me into the magical street.

Tom turns around and walks back to the pub as I walk down towards Ollivanders.

A small bit of information about me could be useful I guess, the name's Arc, Christina Demi Arc, and I'm a Dimensional Traveler

I have waist-length black hair and my eyes are a very light shade of blue, almost like clear Blue Apatite, if we are to go by Harry having Green Emerald eyes that is, I'm wearing a Hogwarts uniform in black, that signifies I've yet to start my first year. I've been in this world three weeks, and work for Ollivander as an assistant until the school year begins.

In my pocket I have a wand holster with a 9 and a quarter long wand made of a "nimble" Cherry Wood and a Dragon Heartstring, and I still giggle when I think of the fact that Lockhart and I have the same type of wand, even if my Dragon Heartstring is from a Japanese Bonescale and his apparently was from a Venezuelan Stalker.

As I enter Ollivanders I almost walk into Professor McGonagall, and hear Ollivander mumble about the wand being wrong, again

"Oh, hello Professor McGonagall, on another fun guiding tour?" I ask, smiling at the older lady, who instantly gives me a glare that says 'Shut it'

"Miss Arc, I trust you are behaving during your stay at the Cauldron?"

"Of course ma'am." I say as I notice the Indian couple and their twin daughters next to Ollivander.

(Must be the Patil's right? If I remember what Mister Ollivander said about wand woods, Parvati would get a wand of Walnut wood… maybe Black Walnut?)

"Ah, here we go, Black walnut, ten and a half inches, unicorn hair, give it a wave" Ollivander says as he hands a wand over to one of the twins, who gives the wand a wave and creates a small shower of sparks

"Perfect, I believe we've found your wand, Miss Patil, let's now find your sister hers" Ollivander turns, but notices my small smirk and smiles

"Miss Arc, what wand would you guess works for Miss Patil?"

"Either a Beech or a Cypress I think sir, I'm not completely sure of the core, but I think we should try unicorn hair first"

"Interesting choice, try this wand Miss Patil" Mister Ollivander hands over a small Cypress wand to Parvati, who waves it, producing sparks

"Ah, perfect fit at first try, Cypress, eleven inches, Dragon Heartstring."

I give mister Ollivander a small glare as he smirks at me, and nods to the Patils "that would be a total of 14 galleons."

As soon as the family left, I groan at mister Ollivander who gives a small laugh

"Knowing them does not mean you know the wand Miss Arc, I've told you before, there's more to a wand than the personality of its wielder"

"I know sir, that's why I guessed Cypress for Parvati rather than just Beech…" I glare at the old man, the only one to know my truth

Exactly 20 days earlier I fell down from the roof in his office, smacking my face into the carpet, both of us in great shock from the surprising entry, him, because I literally did not exist before I suddenly fell, and me because I was suddenly faceplanting a rug, instead of simply waking up outside an orphanage.

Our shock only increased as an owl entered the window, with a Hogwarts letter for me, addressed to "Christina D. Arc, Ollivanders Office"

When we managed to speak, we quickly decided that we'd work together to establish a presence for me, as his assistant and niece, so as to not reveal the mysterious nature of my existence.

I managed to keep quiet about the fact I knew the future for a week, before accidently screaming out in shock as I read the prophet about "Sirius Black's innocence proven" both me and Ollivander were confused before I told him about the fact that it was several years to early, ever since then, Mister Ollivander has laughed at me, and tried to make it a lesson about expectations when I've been surprised by the simple fact of being wrong about something.

"Are you listening?" he asks, snapping me out of my reminiscing

"Sorry, sir, just had a small thought overwhelm me again, what did you say?"

"That Lockhart is the perfect proof that the wand can contradict its wielder, Miss Arc…"

"Right, Cherry wood, Dragon Heartstring, the combination saying the wizard should be incredibly strong-willed with exceptional self-control and power… which honestly neither me nor Lockhart fits more than a single point of the three…"

Mister Ollivander tilts his head, before nodding "Ah yes, he does have to have quite an exceptional Self-control to not show anything hint of being a fraud"

We both give a small laugh at that before he shakes his head at me.

"Anyway Miss Arc, it seems you'll have an interesting year at Hogwarts after all, Miss Zabini was here with her mother to get her wand earlier, with them came Walburga Black, I managed to get Mrs Black to agree to meet with you at the cauldron in an hour, so be careful, the woman is very weak, I do not think she'll live to the end of the year."

I nod, as I mentally go over the plan once more.

Step one: meet a Black family member
Step two: get a reason to meet the Tonks and a way into Grimmauld Place
Step three: meet Nymphadora, the Metamorphmagus so I can get lessons in shapeshifting

"Right, so you made an excuse for me to meet her, what was it?"

"You are Regulus Black's Daughter" he says, giving a giant grin

"…"

Garrick Ollivander, you are the biggest arse a dimensional traveller could meet…

Yeah I know, so far it's p-crappy, but it's me writing it XD I hope everyone likes it, the following chapters will be from Chrissy's POV, maybe one or two out of Harry's or someone else's

Christina Demi Arc is my "Jumper" but those of you who don't know/care about Jumpchain, don't worry, it's not a part of the story, she's only a Dimensional Traveler, meaning that while she got magic, she don't have ANYTHING Jumpchain related

Chrissy D. Arc, Chrissy Dark, she was named to fit into a One Piece world, but i think she works well here too.

Hope you like the story, and the new segment divider, I'm gonna keep it around. PLEASE REVIEW! Tell me how to improve!
