The Defenders of Hogwarts

Summary: Harry makes a friend in the muggle world who is familiar with magic. The two make it to Diagon Alley were they learn their destiny is tied to at least two others. Nadia, granddaughter of the dark lord and descendant of the four founders teamed Harry, the boy who lived but who is the one who could have been and the girl with seer's blood? Pairing will be included later.

Prologue: Before Hogwarts

A/N: After reading an article on Pottermore I decided to rewrite the story and change some of what I had planned.

5 years before Hogwarts – Age 6

Harry sighs as he sits in a quiet corner of the playground, hoping that Dudley will be distracted by the new student and leaves him alone. Just as he thinks that the new student, a girl the same age as Harry flops down onto the grass beside him. She has light red hair and hazel eyes and is just above average height for her age.

"So I've heard all sorts of ridiculous stories about you this morning but since I've learned to never judge a book by its cover I figure I will come talk to you." She announces.

"You might not want to do that, it isn't the best way to make friends around here." Harry replies.

"I was hoping you'd be my friend." The girl replies.

"My cousin won't like that." Harry states.

"And way should that bother me?" The girl quizzes.

"He has a tendency to solve things with violence." Harry answers.

"I go to lessons every Tuesday and Thursday to learn mixed martial arts, we're told only to use it in self-defence but I can spar with boys bigger and stronger than me and win because of my flexibility. Mum swears it is the ballet that makes me flexible but I do yoga as well and that helps too." The girl responds unconcerned.

"Don't say I didn't warn you. My names Harry Potter, what's your?" Harry shrugs holding out his hand.

"Nadia Cane" Nadia replies shaking Harry's hand.

2 Weeks Later

Nadia and Harry after two weeks are becoming really good friends, then in class Harry's accidental magic makes the teachers wig blue. Harry thinks that this will finally end his friendship with the girl who did indeed defend herself against Dudley and his gang though none of them had admitted that a girl more than half their weight had got the drop on them.

Harry goes to meet Nadia at the edge of the park near the trees. "So that was a pretty sweat piece of accidental magic there Harry, this is great we can go to Hogwarts together and still be best friends." Nadia grins.

"Di there is no such thing as magic." Harry corrects.

"Yes there is, watch this." Nadia argues and makes her hair a violent shade of pink.

"Ok so magic is real. Hogwarts must be some kind of school then?" Harry asks.

"Yes they say it is the best but I wouldn't know if that is true or not. It is in Scotland somewhere but you get the train from platform 9 ¾ in Kings Cross station and then off you go. There are four houses and you learn also sort of magical things." Nadia answers.

For the next four hours Nadia tell Harry about the magical world and about Voldemort and how Harry is famous – showing him one of the books he is in and newspaper clippings from the time. "You have a lot of stuff about me and Voldemort is that why you are friends with me?" Harry asks.

"No, I am your friend because you are kind and honest and I like that in a person. Honestly you're like the brother I wish I had and I have this stuff to remind me that no matter what the ministry believes that Voldemort is dead but I know he isn't since his name hasn't gone black on the family tree. I tell you this in the upmost confidence. Voldemort is my grandfather and I am a direct descendant of the four founders of Hogwarts." Nadia confides.

"Is there a way to see people's minds?" Harry asks.

"Yes but there are ways to protect yourself too, we can work on one that requires meditation and building walls and defences in the mind." Nadia answers.

From that day on Harry and Nada routinely practise meditation to begin building shields for occlumency later.

1 Year later – age 7

Harry and Nadia are sitting in the park on the 30th July. "Happy birthday Di, I am glad we went to Gringotts last month and sorted out my account. Here I got you this for you birthday." Harry states.

"Oh Harry thank you it is beautiful." Nadia grins as she opens the simple gold locket, on it is a single ruby in the centre and inside a moving photo of Nadia and Harry laughing that had been taken by Nadia's mum the week before. One the other side is a mirror.

"It is a two way mirror; I had it connected to the mirror that is in the pocket watch you got me last year for my birthday." Harry explains.

"Oh that is brilliant this means we can keep in touch no matter where we are. That is wicked because no one will think that it is anything other than part of a decorative necklace or watch." Nadia grins.

"Thanks for getting my families crest put on the watch, it means a lot to have that connection to my family. Now we both have a ruby from the other, did you know that ruby is the birthstone for those born in July?" Harry asks.

"Yes it didn't take much to find that out." Nadia answers.

"Are you looking forward to starting school in September?" Harry asks.

"Yes, mum has arranged for the two of us to attend Mahoutokoro in Japan, that's why she taught us Japanese and made sure we are fluent in it. We will attend there until we turn eleven at which point we will go to Hogwarts." Nadia replies.

"But won't my aunt and uncle be a problem?" Harry asks.

"Nope, mum got them to sign the paperwork that gives her guardianship of you so you are going to be coming to live with us. Mum thinks we should move into the Founder's retreat as it has wards as good as Hogwarts should be and it has an international floo connection which we can use to get to school." Nadia grins.

"I don't have to go back to the Dursley's?" Harry asks.

"No, you don't and since none of your important or valuable stuff is there you don't have to back there for anything." Nadia grins.

"Wicked, do you think you mum would sign us up for summer classes at Uagadou, for alchemy and self-transfiguration?" Harry quizzes.

"She'll see the merit of it and have the paperwork filled within the week I'd bet." Nadia laughs.

"We have a social event coming up that we need to be prepared for, mum's friend Lady Longbottom is coming to visit to discuss the latest politics and she is bring her nephew Neville so we need to entertain him." Nadia explains.

"That's good, a new friend for the two us if we give it a chance." Harry responds.

2 Weeks later

Neville proves to be a shy boy the same age as Harry and Nadia. "Wow your aura is really bright with lots of green; you must be wicked good at herbology." Nadia exclaims.

"You can see auras?" Neville asks.

"All my life, I use to freak my mum out before we figured it out always declaring that she had pretty colours and hiding behind her at times whispering that the person she was talking to had bad colours. You share that gift with Harry and I but it isn't active in the two of you yet. You also have the aura of one with an elemental affinity with a specialisation in earth; you might find a special interest in herbology." Nadia explains.

"I really like herbology and like the greenhouses at the Manor a lot, the plants grow really well when I tend them." Neville admits shyly.

"I've heard that the brightness of a person's aura relates to their magical strength and the strength of their accidental magic." Lady Longbottom states.

"That's true, Harry's is really bright and he does really impressive accidental magic. Neville's is as bright as his but it is calmer like someone who is really centred and doesn't do a lot of accidental magic. Harry's was all swirly and aggravated but it is mellowing now because we meditate and focus on calming and centring ourselves." Nadia explains.

"That would explain why we have seen very little to indicate accidental magic, Neville has to mediate for a half hour in the morning and also in the evening." Lady Longbottom muses.

From that day on Neville became friends with Harry and Nadia.

3 Years later - Age 10

"I think that this meeting with the goblins is going to be really interesting. I mean they asked if we are familiar with occlumency so whatever it is must be important." Harry states.

"I think we are going to learn why Voldemort targeted you as a baby." Nadia states.

"Do you know that I've stopped questioning your statements like that?" Harry asks.

"We've been friends for four years, you've gotten use to me making statements like that." Nadia responds.

"They are usually right as well." Harry grins.

"I can't help that I get these feelings about things." Nadia shrugs.

"It's cool, you're like a human magic 8 ball." Harry laughs.

"Please do not compare me to that stupid toy that people like so much." Nadia glares, her hair going vibrant red.

"You know, the vibrant red hair suits you Di almost as much as its usual lighter red." Harry offers.

"You Harry are trying to distract me from magic 8 ball comment." Nadia observes.

"Is it working?" Harry quizzes.

"Yes." Nadia groans. "You know I don't stay mad long." Nadia adds.

1 Week Later – Gringotts

Harry and Nadia make their way to the wizarding bank, both had their appearances concealed. Nadia and Harry had discovered during their summer classes at Uagadou that Harry's Black ancestry was prominent in the manifestation of latent metamorphous abilities. Nadia through the Gryffindor line also showed the same ability but had been born with the talent active and thus taught Harry to control it.

The summer lessons had taught the pair much about alchemy and both managed by the end of the course to master the animagus transformation; Harry turns into an 'adorable' ("don't call me adorable Di, I'm a wolf so I'm fierce") wolf cub and Nadia turns into a 'cute' panther cub ("I like being cure and fluffy it's a total compliment for my form.") – The pair know that their form reflects their age and will grow as they do.

Nadia's natural appearance could pass for Harry's sister with long red and hazel eye but she has changed her hair to blond and left her eyes. Harry has taken on the appearance that next to his natural appearance is his most comfortable, lengthening his hair to his chin and making it a red that matches his mothers, leaving his green eyes. The pair had agreed to only change their hair and for Harry to hide his scar - a feat possible for up to 2 hours that had been growing with practise.

"My name is Nadia Cane and this is Harry, we have an appointment with Inkeye." Nadia states once the goblin teller looks up to them.

"I will have you escorted to his office." The teller says nodding to another goblin.

"Hello Griphock, I hope you gold is flowing well today." Harry states unknowingly winning the respect of all the goblins present to hear his greeting.

"Yes, I hope good fortune has been with you since our first meeting." Nadia states after Harry which leads to her too winning the goblins respect.

"Indeed it has Mr Potter, Miss Cane, time is money let's get you to your meeting." Griphock responds -slightly stunned by the respectful greeting from two such wealthy clients.

"Then let's not waste it." Nadia agrees indicating for Griphock to lead the way.

Griphock leads Harry and Nada to the office of Inkeye, the account manager for both the Potters and the Founders (who created a joined account that could only be accessed by one of all their lines, the vault for the Founders Heir – prophesied by Rowena Ravenclaw herself). Both ten years olds greet Inkeye in the same respectful tone they used with Griphock. "Thank you Griphock may your gold flow strongly." Nadia states.

"Thank you, may good fortune be with you this day." Harry adds.

"May your enemies tremble and their souls tremble with your wrath, Mr Potter, Miss Cane." Griphock replies.

Griphock departs and word spreads through the goblin nation not to be shared with the wizarding world that Mr Potter and his friend Miss Cane are respectful and are to have the respect of the nation should their behaviour remain as it is.

Unaware of this wildfire news, Nadia and Harry sit across for Inkeye.

"I have much to discuss with the two of you, some pertains to individual inheritances which you both have so I shall ask if you wish to discuss those matters individually or if you wish to be present anyway. Another matter pertains to prophecy and potentially involves two other, one we believe is Neville Longbottom and the other we have been unable to determine. Lady Longbottom wishes to test this and will be here this afternoon giving us all morning to cover you inheritances." Inkeye explains.

"Sir, Nadia is like a sister to me and I would like her to be here when my family estate is discussed as I may need her council on matters that I am unfamiliar with." Harry responds.

"Sir, l agree with Harry that we are like siblings and as such would like him here." Nadia agrees.

"Please call me Inkeye, Miss Cane, Mr Potter." Inkeye requests.

"You may call me Nadia." Nadia states.

"You can call me Harry." Harry adds.

Inkeye nods at the request and from there they discuss Harry's family estate and sort out details, no outgoing transactions are flagged as none have been added since the death of Lily and James and the current ones are standing transactions for the maintains of the estate.

At Nadia's advisement, Harry becomes financially independent and requests that all withdrawals not made by Harry and not related the maintenance of the estate be questioned and denied (being stated as a stipulation of his parents will which after reviewing the document should be in place with the exception of Sirius Black, Harry's godfather who may withdraw money towards the care of Harry).

Inkeye informs the pair that there was never a formal trail and that legally Sirius is still Harry's legal guardian. The will also explained about the switching of the secret keepers and that Harry is not under any circumstances to end up in his aunt's care. Intending to keep their independence to themselves (Nadia's mother having given her that independence when they learned of the inheritance) they decided that they cannot act directly and must find a way to get a trial for Sirius with the use of Veritaserum and or the use of a pensieve to view memories.

A well written untraceable letter to Rita Skeeter consider carefully illusions to the lack of trial records and implications that there are rumours that he is still recognised by magic as Harry's godfather (a right with would have been lost had he acted to betray the oath of protection and care that comes with being godfather to a magical child) and the letter is good to go. However the pair agree not to send it yet and decided to wait for an opportunity to do so.

Nadia's inheritance takes less time to discuss and much of what is said is merely a review of the actions taken now that Nadia has claimed her inheritance. The pair then arranges to return to the bank at 3 O'clock and head into Diagon Alley after withdrawing money from their vaults. They go to the Leaky Cauldron where Nadia's mother is waiting for them and the three have lunch, after they then get ice cream from Florean Fortescue's. Nadia got a banana ice cream and Harry a peanut butter ice cream.

Nadia's mother accompanies Nadia and Harry to the meeting with the Longbottoms. The meeting begins with all being sworn to secrecy – a spell similar to the fidelius charm but for a secret not a location, it also prevents the person communicating the secret to someone not sworn in on the secret.

First of all I would like to have one of our curse breakers cast a modified revealing spell that will tell us if the three youngsters are indeed the children of the prophecy. 'We are' Nadia signs to Harry who is the only one to understand muggle British sign language, both also have been taught wizarding sign language which is international and with no regionally difference. The curse breaker is sworn to secrecy and casts the charm; it glows green confirming that Harry Potter, Nadia Cane and Neville Longbottom are the children of the prophecy. It shows the other is a year younger and also British in origin but does not give their name.

Inkeye the sits everyone down and tells them about the prophecy made about Harry and Voldemort (everyone flinches when the name is used bar Nadia and Harry) "Fear of a name only increase fear of the thing itself" Harry quotes. Inkeye arranges for Harry to retrieve the orb containing the prophecy without it raising any attention. With the orb of the prophecy that was made the year he was born collected it is shared, Lady Longbottom gasps, "That could have been Neville".

"We know that is why he is here. Let us share with you the prophecy of Lady Ravenclaw herself." Inkeye responds. The prophecy concerning the four youngsters is shared;

The boy marked as the dark lord's equal shall join with the boy that could have been. They shall be joined by two girls in symmetry with the Founders of Hogwarts. One shall be the Founders Heir herself and she shall have the powers of her ancestors and blood rite over Hogwarts, through her they shall learn the truth of the Founders. The fourth is a year younger with the blood of a seer and together the four shall be the defenders of Hogwarts, restoring the great school and protecting it from the dark. They shall be united and lead the fight against the dark lords, together they shall defeat the dark lords.

Everyone is shocked. "Well I it is a good think the three of us are good friends because I know you don't lead a fight with people you don't trust to watch your back." Nadia announces.

"Excellent point Di, I am glad that we are aware of this before we start Hogwarts though, gives us a chance to figure out who the fourth is and get to know them and it means that we will have a chance to figure out how to go about all of that." Harry agrees.

Soon it is a week before Hogwarts letters come out and the three meet to discuss how they will act in the coming year; it is agreed that the three will meet in the alley and 'become' friends with Harry and Nadia who will go together. Harry sends his acceptance with Nadia's using her eagle owl, Nyx.
