Chapter 1: The Pure Hearted One

Snape POV

Standing with the other Death Eaters, Snape patiently waiting for Lord Voldemort apparently all the death eaters were all gathered. Snape thought that this must be urgent rather very important if all the death eaters were gathered in one place, While thinking on what the gathering of all the death eater were all about a flash of black smoke was travelling to where Lord Voldemort should be standing, as the black smoke reached it then appeared Lord Voldemort himself.

"M-My Lord what is it so urgent that you su-summoned us all here?" Wormtail said almost regretting to ask the question as almost all the death eaters glared.

"Ahh I'm glad you asked Wormtail" Voldemort said as nagini slowly made her way to Voldemort glad to see her master come back.

"Apparently other than the Boy-Who-Lived, It seems another threat is upon us" Voldemort said looking unpleased when he heard about it the first time, but saying it made him more unpleased.

Noise errupted by the Death Eaters hearing what Voldemort said "I'm sure whoever this person is no match against you my lord" Bellatrix said reassuring his Lord has nothing to worry about and shall be easily dealt with. As the noise was calming down Snape then asked "My Lord I ask to lend me the name of this threat so I can swiftly deal with it as well as giving you one less to worry about." Snape said the same time the noise calmed down.

"If only it would be that easy Severus" Voldemort said.

"Forgive me on pressing the matter my lord, but how come?" Snape said calmly, He wondered why he can't give the name of the said threat.

"For I don't know the name is why" Voldemort said flatly after a smirk can be seen on his face telling his death eaters that he did not came back emptyhanded.

"I may not know the name, Yet this threat was given the title of 'The Pure Hearted One'." He said, He saw his fellow death eaters confused on what he said.

Whispers as well as conversations were upon the death eaters thinking on who this "The Pure Hearted One" it was then followed up by why was it given the title of "The Pure Hearted One".

"I expect you wish for us to find this 'Pure Hearted One' my lord?" Snape said, and as he expected Voldemort nods after which one by one the death eaters left doing in their power to find this "Pure Hearted One".


Location: Headmaster's Office

Dumbledore was waiting for the quill to stop writing on the book, since the quill was writing those new students who were to come to Hogwarts this new school year, what was interesting is that the quill will stop midair with a harmless blue fire emitting from it signaling a powerful or rather a Wizard or Witch that have a great future ahead of him in the wizarding world, Just like when harry potter was at age to go to Hogwarts the quill stopped midair with a harmless blue fire on it then Dumbledore held the quill, he then started writing on the book which he wrote harry potter's name, Suddenly a knock came from the door.

As Snape knocked on to the Headmaster's office and went in, Dumbledore knew that snape brings important information about the dark lord since he didn't give snape permission to go in yet.

"What is it Severus?" Dumbledore said in a calm yet somewhat serious tone while eating some lemon drops.

Snape recaps to Dumbledore on what happened on the gathering Mainly on the "The Pure Hearted One" which interested Dumbledore as he never heard of such a title or the reason behind the title that was given to the person.

"Hmm.. It would seem we as well have to find this person, Though I fear it would give us a challenge to find this 'Pure Hearted One', since we don't even know it's name" Dumbledore said, it was true that they don't have a clue on who it is even a clue relating to the person would have been helpful, When suddenly the quill stopped midair as a blue fire was emitting from it, with Snape being surprised when he saw the quill as he recall the last time it did was when harry was of age to go to Hogwarts, with Dumbledore surprised aswell, he took the quill and let it control his hands to write who was the wizard or witch was it about to write.

When Snape was watching Dumbledore write on who the new student that will come to Hogwarts he noticed Dumbledore's eyes widen as if he what he wrote was an important person to him, Snape asked on who it was Dumbledore turned the book so that Snape could read the name written on it and what he saw written was not he was expecting.

Oliver

The Pure Hearted One

"It would seem Luck is on our side Severus, Wouldn't you agree?" Dumbledore said with a smile on his face.

"Severus can you inform the Order that there will be a meeting tonight and that it is urgent we must tell the order about your report and to send escorts to pick up Oliver as we never know when one of the death eaters will know the whereabouts of this boy" Dumbledore said.

After which Snape then Stood and hurried out to go inform the order about the meeting that will take place tonight, While Dumbledore took out a quill and parchment to write the Hogwarts admission letter to Oliver along with it for Dumbledore to know where Oliver lived.


Location: 12 Grimmauld Place

"The Pure Hearted one huh, Looks like my godson has a rival now" Sirius said smirking.

"This isn't something to joke about Sirius, who knows what would have happen to him Oliver I mean, Another is explaining to him that magic exists along with his parents explaining to them that their son is in danger." Molly said as she was worried for Oliver and knowing how he will take it all in.

"Calm down molly I'm sure the kiddo will be delighted to know that magic exist I almost see all muggle children pretending to be wizards and witches because of what they watch in that big screen in those giant building" Tonks said trying to lighten 's mood which it worked as Mrs. Weasley was happy that there were muggle children dreaming of becoming wizards and witches even though they didn't know that magic do exists.

Meanwhile outside the room where the order are conducting their meeting appears to be an ear an authentic one at that attached to a thin string at the end of the string however were the Weasley Twins Fred and George, Ginny, Ron, Hermione and Harry listening intently to what the order was discussing with Hermione almost hogging the ear to herself to hear what the order was discussing.

"Blimey harry looks like their are two chosen ones then, You and this Oliver fellow" Ron said trying to entertain them as he knew harry was worried about Oliver even though they haven't met yet.

"Looks like we have to prepare a welcoming party for Oliver ain't that right George?" Fred said Enthusiasticly.

"Right you are Fred we might be able to try one our new invention on him" George exclaimed excitedly when Hermione glared on them telling them to be quiet as she was starting to barely hear the Order's conversation.

"Hmm.. I wonder why he was given the Title though I mean like what did he do exactly to be given such a title?" Ginny said which she made a valid point.

Waiting for Hermione to make a theory on the title, but even she too had no Idea why he was given the title of 'The Pure Hearted One' let alone what the title means as she was pretty sure the title wasn't anywhere on any book she read ever since she came to Hogwarts though she thought maybe there's one on the restricted section in the library at Hogwarts.

"So. When are you gonna pick up Oliver, Dumbledore?" Lupin asked

"Well I already sent his letter containing his admission to Hogwarts that is why we have to pick him up today before the Death eaters learn who 'The pure hearted' one really is, I'll be the one to explain to him about Hogwarts instead of Minerva this time and you Remus, Tonks, Alastor and Arthur will accompany me in case any death eaters do show up, and to explain to Oliver's parents about magic existing Arthur." Dumbledore said as they all stood up and reached the fireplace as they will travel by way of floo network, One by one they all stood taking a handful of Floo powder and shouted Oliver's address.


Location: Oliver's House in Motorville

As Dumbledore stepped out of Oliver's fireplace he saw Moody, Remus, Tonks and Arthur raise their wands pointing it across the house as he looked across, There stood A figure as tall as Hagrid who was wearing a mask shaped like a rooster holding what Dumbledore would assume was his wand or a staff to be precise after which a battle of staring were going on, at about after a few seconds the figure spoke.

"Put down your wands for I am not here to hurt anyone, My name is Gallus" Gallus said after a few moments of hesitation they all lowered their wands as Dumbledore spoke.

"May I ask on who and what are you doing in Mr. Oliver's House, ?" Dumbledore asked as he scanned the room he noticed there was no one in the living room granted that it was already night time, yet he felt like something was wrong.

"Like I said I am Gallus that is all you need to know, as for What am I doing to young Oliver's house I was simply protecting him in case of any to what you all refer to as death eaters comes along, all while waiting for your arrival to pick up Oliver and keep him safe." Gallus said as he saw Dumbledore's presumed escorts sigh a wave of relief.

"Well now didn't think we find a new recruit to the order here right Dumbledore?" Tonks said positively as when she first saw Gallus she thought he could overpower them as he does look intimidating and powerful aswell.

After hearing what Tonks said Gallus laughed a bit almost as if he told them that they were wrong about him, afterwhich Gallus then told them "Don't be hasty on your judgement on me yet, for yes I am not your enemy, nor am I also your Ally" from his remark Tonks, Remus, Moody as well as Arthur were now on alert they almost raised their wands again until Dumbledore stepped in and asked.

"Mr. Gallus I must ask on the reason to protect Oliver surely you must have a reason to do so." Afterwhich Gallus stared at Dumbledore and was amused with him, he then knew the young Oliver will be safe at their care.

"There are two reasons as to why I was protecting young Oliver, for one he saved my daughter the second which was a request from my daughter, she sensed young oliver will be in danger, That is why she sent me here until he was picked up by the headmaster of the school he was admitted in which I presume you're the headmaster of the said school." Gallus said firmly.

Fascinated to what Gallus said, Dumbledore thought of how did Oliver save Gallus' daughter does he already know magic exist? Who was Gallus' daughter?

"Doodle-Doo." Said a girl running down the stairs who has short green hair and blue eyes and is wearing a white dress with white shoes.

"Ahh.. young Pea, Young Oliver's Headmaster has come to pick him up, Do not worry young pea as even I put my trust in them" Gallus said to the girl.

"Yay" said the young girl happily as she nods to Gallus.

"We must take our leave" Gallus then gesturing to Dumbledore and his escorts "Young Oliver is in his room upstairs in the first door, He has already received his letter from Hogwarts though I doubt he already read it as he was very tired, I must ask of you to let him rest and just carry him to your headquarters" Gallus said as he turn his back, he noticed that the girl wasn't coming with him he asked "Young Pea is there a problem?".

The girl Shooked her head as she said happily "I wanna help Oliver because he helped me".

"Very well, Do take care of yourself young pea" Gallus said as he disappeared from the room.

As the girl waved back goodbye to Gallus she then turned to Dumbledore and happily said "Hello my name is Pea."

Dumbledore Smiled and said "and My name is Albus Percival Wulfric Brian Dumbledore, and these here are" Dumbledore gestured to the other four who introduced themselves one by one.

"Young Pea do you know that magic exists?" Dumbledore asked as he was curious of the child.

"Yes" Pea said Happily as Tonks, Remus, and Arthur were surprised not only she was underaged how come the ministry never detected that underaged magic was being used here.

"and as to why we are here, we came here to get Oliver as he was admitted to Hogwarts a School to train a person's magic capabilities" Dumbledore said calmly to Pea.

Pea nodded and said happily "I know" after a moment Pea's Smile faded and said "Please protect Oliver, The evil wizard is coming".

They were now on high alert on what pea said, is Voldemort coming right now? If he is how did Voldemort found out that Oliver is The Pure Hearted One? As they were on high alert Dumbledore kneeled to Pea to meet her eye to eye.

"I can Assure you young Pea that Hogwarts is the safest place here in the wizarding world as I casted multiple protective charms on Hogwarts you can rest assure Oliver will be safe." Dumbledore said calmly to pea after which pea was smiling again.

"Now do you know where Oliver's parents are, Young pea?" asked Dumbledore yet pea's smile was gone again.

Pea Shooked her head as she said "Oliver's Mother died 2 years ago, and I couldn't save her".

"I am very sorry to hear that young pea" Dumbledore said as he lower his head.

Pea Shooked her head again and smiled as he said "Don't worry Oliver's fine now he's made lots of friends already, Here" she gave a letter to Dumbledore as he tore it open he was surprised to see it was a permission slip to go to Hogsmeade for Oliver as it was signed by Gallus claiming to be Oliver's Guardian, Even though he hadn't sent it yet with Oliver's Admission letter to Hogwarts he can see that it was the official permission slip they had back in Hogwarts he wondered for a moment on how they got the letter, but was put to a halt when pea said

"Bye-Bye" she as she took off running leaving Oliver's House.

"Wasn't she going to go with Oliver to Hogwarts? She did say she wanted to help Oliver" Tonks said with a perplexed face, as Dumbledore got up and face them

"well then that was interesting, Looks like this Oliver knows how to use magic" Moody said as he drank from his flask.

"You don't know that maybe those two were just actually guardians of Oliver" Arthur suggested

"No Arthur pretty sure Oliver might already know magic exists and I'm even sure he can use them aswell" Remus said quickly shutting down arthur's idea.

"hm.. Yes that Gallus did say Oliver saved her daughter along with the girl pea saying the evil wizard is coming which I'm sure was referring to Voldemort" Tonks said which Moody and Remus agreed.

"Whatever the case is we should get to Young Oliver and bring him to Grimmauld place before the death eaters know of his whereabouts" Dumbledore said as lead them to Oliver's Bedroom.

As they were approaching the stairs they came across a portrait of a boy who they thought is at the age of 9, The boy had blue eyes with brown hair with a tiny tint of redness on it and was wearing a yellow shirt and blue trousers which are held up by suspenders.

"I reckon this boy here is Oliver" Tonks said holding the portrait as Remus approach her.

"hmm.. yes, and his mother I presume" Remus said as he pointed the woman next to Oliver who also had blue eyes with brown hair.

As they reached supposedly Oliver's room they found Oliver sleeping quietly in his bed holding a bag on his left hand while holding a Book on his right hand on top of the book was a letter, As Dumbledore looked closer on the letter it was apparently the letter of admission to Hogwarts, It wasn't opened yet as Dumbledore saw the seal on it was still intact.

"So this is the Pure Hearted one" Moody said as he looked at the sleeping Oliver "I Suggest to not wake him seeing as he didn't open the letter yet and be confused to who we are, I assume he must have been really tired" suggesting the idea as he took Oliver's bag and saw that Dumbledore approved of the Idea.

"Oh! This seems to be a wand don't you think?" Tonks said pointing at Oliver's side what she thought to be a holder of the wand, The assumed wand was different than they usually use as it has this three round balls attached to it she thought.

"Don't you reckon maybe it's a toy Arthur? You did say Muggles are capable of making a toy maybe this is one." Moody asked Arthur but was cut off by Dumbledore.

"No, this is indeed a wand Alastor I can feel magic from it, But to how young Oliver obtained it is a mystery indeed" Dumbledore said as he further examine the wand.

"Nevertheless we can ask young Oliver about it once he wakes up, for now we ought to get him to Grimmauld place" he said as he put back the wand to where it was.

Remus carried young Oliver while Tonks and moody carried what supposedly were Oliver's things (The book and the bag) while Arthur made sure that there were no muggles approaching since they didn't want them to find out that magic exists. As they reached the fireplace Dumbledore turned around to face them telling them he has business at Hogwarts to attend to and to make sure Oliver gets to safety. As he left Remus, Tonks, Moody and Arthur left one by one by the use of Floo network back to 12 Grimmauld place.


Location: Grimmauld Place

As they exit the fireplace they were met by Molly and Sirius with molly immediately taking a liking to Oliver as if she had another son to take care of. She lead Remus and Tonks to a room she prepared for Oliver where they laid Oliver on the bed. They all left as they put down Oliver's bag and letter from Hogwarts, after which Remus asked Tonks on where was Oliver's book and apparently Moody said he'd examine it first but will give back to oliver once he wakes up.

"Harry, Harry, HARRY!" Harry suddenly woke up looking around to see on who woke him up, He was ready to give the person an earful until he saw ron beside his bed which was apparently the one waking him up.

"Breakfast's ready mate c'mon Hermione and Ginny are waiting for us" Ron said who waited for harry to dress up was craving for eggs and bacon.

As they made their way to the table he saw Fred, George, Sirius, Remus, Tonks and Mr Weasley having breakfast, yet what Curioused him was that there were a lot more food than usual on the table granted the order has a lot of members in it but the amount of food on the table were overwhelming as if they were having a feast, when harry asked why there were more food than usual whipped up 4 plates for them then answered.

"Well there's someone new I wanted all of you to meet" Not sure what Mrs. Weasley meant he Thought Maybe there's a new member joining the order? Yet he shutdown the idea since Mrs. Weasley never made this many food when a new member joined in, Seeing so many food on the table he then decided on not thinking about it as he too was very hungry.

"Ah this is Impossible" looking around on who said that was Moody coming down the stairs holding a book, as he reached the dining table he put down the book on the table, then grabbed himself a plate and helped himself with the food that was set on the table.

"Um Prof- Moody where did you find that book and can I read it?" Hermione said nervously as Moody looked at Hermione then to the book.

"Bloody Hermione you already have a lot of books to read this summer and you're gonna add one more?" Ron said as he stuffed himself more of the food.

"Well it's better than doing nothing almost the whole day Ronald" Hermione replied as he glared at Ron.

"it's no problem granger.. if you can open it that is" Moody said while drinking from his flask.

Perplexed at what Moody said Hermione hesitated but reached for the book and tried opening it, as she was about to flip the cover of the book flames were then emitting from it, shocked at what happened she quickly dropped the book on the table there was a slight burnt on her hands but was nothing too serious when she looked at the book again there was a flaming text written on top of the book that was not there before she read:

The Property of the Wizard King none shall be able to open Unless given Permission

After a while the flaming text then disappeared, looking around she saw the people other than moody were surprised to what they saw.

"Are you hurt Hermione?" Ginny asked as she took a closer look at Hermione's hand.

"Don't worry its not serious" Hermione replied.

"I've been at it all night you know tried everything even turned in to a stone tablet then reverted back to the book after a while" moody said as he reached to get more bacon.

"Wizard king huh, D'you reckon it means Oliver?" Tonks suggested, yet regretted saying it at the end as she saw Harry, Hermione, Ron, Ginny, Fred and George look at her clearly ready to ask her a lot of questions.

"Yep, that's why I came down thought he would have already awaken by now" Moody said before the kids can ask Tonks about Oliver.

"Is that why there are a lot of food than normal?" Fred Asked.

"Yes, I expect you all be on your best behavior too" looking at Fred and George "Oliver got here just yesterday though he was asleep apparently, and He hasn't opened his letter from Hogwarts yet so we have some explaining to do when he wakes up" Molly said though she felt like they wouldn't listen either way when she looked at them.

"Right what about we wake him up shall we?" Sirius suggested and saw Harry, Hermione, Ron, Ginny, Fred and George nod since they do want to meet Oliver since he is 'The Pure Hearted One'.

As Sirius got up he picked up his plate and was about to give it to when suddenly a bolt of light came hitting the plate out of Sirius' hand surprised as to what happened everyone in the room looked at the source of the projectile only to find a boy almost same age as him harry thought, the boy has blue eyes and brown hair with a tiny tint of redness wearing a blue vest over a white shirt and white pants with a red cape as well and what seems to be some kind of locket around him while holding what he presumed is his wand? An odd one he thought.

"Wh-who are you?" the boy asked?
