1. Flight From Privet Drive

A/N: Alright, so its been god knows how long since my last update and this isn't even a proper chapter update! The infamous chapter 17 is still in the works, however I'm hoping to get it done soon, as in within the next few days. Currently I have about 3000 out of my desired 6000-8000 words written. That being said, this update isn't without its changes. The majority of the story has been completely and utterly stripped and remade, with the most changes occurring between chapters 1-6 and 8-14. The other 4 chapters are relatively untouched except for grammatical changes and improvements.

That being said, this new story is going to eventually become an amalgamation with another FanFic idea I had a while back, which is why you'll now see the introduction of more supernatural themes and unfortunately (or fortunately) the introduction to some almost classic Hinny FanFic staples. However, this story will not become one of those quintessential pieces of work in which Harry ends up as some deity with a harem of sexy babes behind him. This story will continue to have some darker themes placed into it, especially as the story progresses into the later years. Fluff will still be a highlight of my writing though, as at the end of the day, Rose and Harry's relationship is a vital part of this story.

With that all out the way, there are two people I'd like to dedicate to this new and improved Once a Potter always a Potter. Firstly, to fellow author Breanie, the brilliant author of the equally brilliant Second Chance fic (Which is now over 1 million words long). I thoroughly recommend anyone to go and read this marvellous work. And secondly, I'd like to dedicate this to Ella, my roleplaying partner who has been my muse for a year now. She's stuck with me throughout this entre process and has been there for me to bounce idea's off no matter how absurd they were. So here's to you Ella and to another year of fantastic imagination!

The flight from Privet Drive: Chapter one

So it begins…The way the world ends…not with a bang, but with a whimper.

Once ago, there lived a boy. The boy had unruly black hair and piercing, deep green eyes. His face was bespectacled by a pair of broken old glasses which barely allowed him to see. He was shorter then he should have been, his ribs showed clearly through his skin. Dirt and soot makeup coated his face, fresh blue bruises mixed with fading yellow. This was a boy whose life was not of his making. The boy had a little sister, with blazing auburn hair and loving warm chocolate eyes. Her face perfectly sculpted with every part of her fitting just right. And yet, her beautiful face was pocketed with the same dirt and soot the brother had. Her bruises were few and far between, but her heart bore scars deeper than any cut. Their names...were Harry James Potter, and Madeline-Rose Lily Potter. Unbeknownst to these two young children, as they slept underneath a flight of stairs, that a world unknown to them would celebrate their names until the last days of Earth.

Fate spun his thread; his work was not yet complete. It was time to set the course straight once more.

"Harry! Madeline! UP! Get up!"

Unfortunately for these two young children, their family didn't quite think of them the same way as the rest of the world. Harry and Rose Potter were orphans you see, and their only living family that they knew of happened to be their 'lovely' Aunt Petunia and Uncle Vernon Dursley and their cousin Dudley. Petunia, the sister of their mother, had a face that could have once been beautiful. Brown hair with dashes of stressful grey curls fell down her now horse-like face. Gossip was what made Petunia's dull life revolve. If the neighbour had an affair, she'd know about it before the partner. If the businessman down the road was fired, she'd know before the dismal letter had arrived. Vernon Dursley's life revolved around work for the most part, that and alcohol. The tainted breath of cheap whiskey and stout were his signature breath mints. If he only smelt of stout, then it was a good day to have him around. His manic alcoholism had caused an equal love of gluttonous, fatty foods, which culminated in the rotund figure that was one Mr Vernon Dursley. His greying blonde hair may have once made him look slightly decent, now only served as a reminder of what this man had let himself become. And as the old saying goes, like father like son, Dudley Dursley was a spitting, non-alcoholic, image of his father. A measurement of boulders would be more flattering then stones, his body suited more towards Japanese sumo wrestling then cross country.

And these three individuals had been Harry and Madeline-Rose's family for the last 10 years. Some days were better than others, at least they were fed the measly ration of bread and water. If they were lucky, they were blessed with the burnt fond of dinner. Rose was rather devious in being able to sneak food out of cupboards whilst they worked, earning her brother and herself a snack of stale biscuits or even fresh ones. Then there were the bad days. The days which resulted in Harry being punched, slapped, kicked and thrown against the wall. The ones where Rose would be stabbed with vicious words of self-loathing and hatred. No, life wasn't good for the Potters. The only escape they had were the dreams that kept them sane at night, the dreams about a big red brick house, about a man with dark hair and Rose's eyes and a woman with auburn hair and Harry's eyes. A gentle song sometimes sprung up in Harry's memory, lulling Rose to sleep as he hummed it to her, his arms wrapped protectivity around her. One day they could leave, one day they could ride off into the sunset, hand in hand, and find a new life together.

Fate thought that day…was today. So, he made it be.

The sudden banging at their cupboard had woken Harry out of his slumber. Slowly, Harry opened his eyes, rubbing the sleep from out of them before rolling over to wake his little sister up. Rose slept there, tiny compared to him. He smiled as he took in her sleeping state, glad that she was safe here with him, and that at least they got some time to be together before they embraced another day with the Dursleys.

"Rose, it's time to get up." Harry softly nudged his little sister awake as he turned on the light in their tiny, dingy cupboard under the stairs.

"Mmm, five more minutes, I swear I'll be up." Unfortunately for the both of them, Rose was not a morning person.

Harry had to suppress a snort. "Rose we have to get up, it's Dudley's birthday, and you know how they get when everything isn't perfect for their little Duddikins."

Rose slowly opened her chocolate brown eyes to meet her brothers deep emerald eyes. "Good morning dearest brother of mine, has it really been a year since the fat lump had his last birthday cake?"

Harry chuckled lightly at his sister's comment. "Yeah, I'm afraid so. Come on, don't want to make Duddikins wait any longer."

The two siblings slowly got up out of their cupboard, sharing a kiss on each-others cheeks as they did every morning. Walking into the kitchen they spied Dudley's overtly large pile of presents and the scent of burning bacon in the air. Nothing good ever came from burnt food.

"Hurry up you two! Get breakfast going! Madeline, Go get the mail!" Shouted Aunt Petunia as she thrusted a pair of cooking tongs into Harry's hands.

Perturbed by his aunt's shouting, Harry set about trying to salvage breakfast as Rose went to get the mail, sending Harry a comforting warm smile, letting him know that everything would be okay. Meanwhile, Dudley Looked up from his plate of early morning birthday cake, mouth full to the brim. He looked up at his mother, shovelling another large piece into his mouth before asking.

"Mummy, where's daddy?" As he spoke, pieces of cake fell onto the table to keep their brethren company.

Petunia turned to him with a pale face and looked him in the eye before stating "I'm afraid daddy hasn't come home yet Duddikins, he said he'd be here though so don't worry."

Just as Petunia finished her sentence the front door slammed open and shut as Vernon Dursley walked into the kitchen reeking of alcohol, dragging Rose along with him from the front door. "Woman! That breakfast better be ready! BOY! WHERE'S MY COFFEE!"

Roughly shoving Rose off towards Harry, Vernon plumped himself next to Dudley and ruffled his son's hair. "Happy Birthday Duddikins! Enjoying that cake?"

Dudley turned to look at his father, rather sheepish as he responded to his intoxicated father. "Yes dad, but the freak is taking too long with breakfast!" The accusatory look Dudley sent Harry's way was met by an equally distrustful stare. Harry knew he'd pay for that later.

The glare his Uncle sent was a small relief to Harry. No beating this early. "Hurry up with breakfast boy! And you, Girl! Did you get the mail!?"

Rose looked up to Vernon cautiously before answering him, "Yes Uncle Vernon, the mails on the table for you." Her voice was meek, afraid of saying the wrong thing. Vernon didn't even acknowledge the fact, instead his attention went to sifting through the pile of bills and letters that Rose had kindly fetched.

Rose shuffled closer to her brother, his presence a minor comfort. A security blanket. She remembered she had to tell him something. Her fuzzy mind thought for a moment before the odd-looking letter came into the front of her mind. Her whisper was almost too faint for Harry to hear. "There's a letter for you in the cupboard for afterwards, don't say anything."

Harry shot her a puzzled but thankful look as Rose started to dish up breakfast for the Dursleys. 'Who would be sending the freak a letter?' The small voice at the back of his head reminded him that freaks don't get letters. So, Harry pushed it to the back of his mind.

"Dad, are we going to the Zoo today?" Dudley asked his father out of the blue. Vernon looked up from his morning paper to look at his son. Annoyance crossed his face before his jovial smile returned.

"No Dudley, 'fraid I've got a terrible headache, how about I take you tomorrow?"

"But I wanted to go today! Take me today dad!" Dudley wasn't use to not getting his way. Only the freaks were told no.

So, when Vernon cuffed his own son around the head, the shock around the room was even more. The air thickened as Harry and Rose stood still and watched, waiting for their turn. "I said no Dudley, now eat your cake and shut it!"

Petunia simply looked on as her son quietly ate his cake in silence. She would never speak up. Let the freaks deal with the aftermath, a little scuff around the neck won't hurt Dudley. Breakfast was fairly subdued affair after Vernon's violence on Dudley, and before long Rose and Harry were back in their cupboard waiting to be ordered around for the day. The browned parchment that was Harry's letter stared up at him as he entered their domain, Rose close behind. For a moment he'd forgotten what Rose had said to him. An annoyed huffed came behind Harry as Rose pushed him forward in order for her to fit into the cramped space. Sitting on the bed, Rose passed him the letter before petting the spot next to her, beckoning him to sit and read. Obliging his sister, Harry sat on the old camper bed, a dust cloud coming up from the impact site. Rose pulled a face as her nose itched from the fine particles. Harry turned the letter over in his hands a few times, taking in the odd feeling of finally having his own letter. He distinctly remembered a time in school where his class had all written letters to John Major, he never did get a reply. The address, Harry noticed, was either a cruel joke or very precise.

Mr H. Potter

The Cupboard under the stairs

4 Privet Drive

Little Whinging

Surrey

Harry took a look at the back and noticed the emblem on the back, 'Hogwarts'.

"Well open it up Harry! Let's see whose it from!" Harry looked at the letter once again and slowly opened it up and read it to Rose slowly.

HOGWARTS SCHOOL OF

WITCHCRAFT AND WIZARDRY

Headmaster: Albus Dumbledore

(Order of Merlin, First Class, Grand Sorc., Chf. Warlock,

Supreme Mugwump, International Confed. of Wizards)

Dear Mr Potter,

We are pleased to inform you that you have a place at Hogwarts School of Witchcraft and Wizardry. Please find enclosed a list of all necessary books and equipment. Term begins on 1 September. We await your owl by no later than 31 July.

Yours sincerely,

Minerva McGonagall

Deputy Headmistress

Along with the letter came a long list of supplies and books, including all sorts of odd equipment, such as cauldrons, a wand, spell books, and an assortment of 'potions' supplies. Harry gaped at the letter in disbelief, wondering if this was all a dream or just some sort of joke, or if it was actually real. Somewhere in his mind an imagine of the dark-haired man from his dreams held up a wand and blew bubbles down on him. Rose stared at her brother in disbelief before taking the letter from Harry, looking it over herself.

"Harry, this can't be real, can it?" The disbelief was in her voice. And then fear spread through her. What if Harry left her, what if he escaped? As much as it pained her, she'd let him go. She'd never hold her brother back.

Harry stared at his sister for a bit before finally speaking. "I have no idea Rose, maybe we should ask Aunt Petunia, she might know something."

"Are you serious? That's a terrible idea! She'll tell Vernon, and then we'll...we'll get hit again." Rose started to sob against her brother's shoulder. "I don't want to get hit again Harry; it hurts so much. I don't want YOU to get hit again."

Harry wrapped his arm around his sister as she sobbed into his shirt. "Alright, we won't tell her, but we need to find out about it." An image of his beaten and bloody sister came to the front of his mind. He thought it was his imagination until Harry remembered that it was a memory.

Nodding her head in consent, Rose extracted herself from her brothers' arms and wiped her tears away. "O-Okay Harry, we'll plan tonight okay?"

So tonight, it would be, Fate mused.

Deciding that asking Petunia was the wrong thing to do they agreed to plan a course of action into discovering this so called 'Hogwarts'. Before they knew it, Petunia had them out of their 'room' and set about doing tasks for the day. Harry was tasked with mowing the lawn, tending the flowers out front, painting the front fence with a fresh coat of paint, and lastly sorting out the garden shed so that Dudley could put whatever garden toys he received inside. Rose on the other hand was tasked with keeping Dudley satisfied food wise, bringing fresh pieces of cake and making him a spectacular birthday lunch and dinner, as well as cleaning Dudley's room in order to safely fit any and all new toys that Dudley received today. Vernon's eyes watched her hungrily, making Rose shiver in fear. She'd be a good girl and work hard today, then she wouldn't be punished. Even freaks can be rewarded.

Working in the summer sun took a toll on Harry, and Rose made sure to keep him well hydrated throughout the day, bringing fresh lemonade and even some biscuits as he worked on through the day. Before long, it was dinner time, and Harry had come in to help Rose with the dinner preparations. They sat there in subdued silence as they went about diligently to create a fine meal for their 'loving' cousin and family. They silently dished up the meal and set it about the table, only being allowed a tiny portion of their own cooking and having to sit at the other end of the table, far away from Dudley and his father. Vernon mainly waffled on about drill bits and how the Germans and French were trying to wrestle in on the competition here in England. He made some rather derogatory comments towards the two nations, stating something along the lines of one was a coward and the other was a fascist dictatorship still.

"Bloody Krauts and those Frogs, trying to take away jobs from good, hard working Englishmen! Don't they remember what happened during the war!"

As dinner came to a close, Rose and Harry went about finishing up washing the dishes, waiting for their opportunity to escape to their cupboard so that they could plan what to do with Harry's new letter.

However, their luck ran out not long after they finished the dishes. "BOY! GIRL! What is the meaning of this!" Steaming into the room was a distraught and angry Aunt Petunia, waving in her hand the very letter Harry had received earlier that day.

Fear made his stomach drop. If it wasn't for his strong constitution, Harry was sure his pants would be damp. He tried to cover it up, the wrong thing to do. "Aunt Petunia I can expla- "

"There I was, so lovingly cleaning out your pigsty of a room when what do I find! A letter from that freakish school and that freakish man who left you two FREAKS here with us!" Petunia spat.

Rose's eyes filled with water as fear planted itself in her heart. The acidic smell of urine filled her nose as she realised, she'd wet herself. "Aunt Petunia please, we don't know anything about Hogwarts! We just got the letter this morning!"

By this stage, Vernon was fuming, his face turning a bright red as he stormed his way over to the siblings, "You dare hide from us, your caring family, letters from that freakish world! Well, I think there's only one course of action isn't there!"

Petunia looked on in disgust as her husband grabbed the freshly washed iron skillet. Vernon weighed it in his hands a couple of times before he set his sights on Rose. The small grin that haunted her memory reared itself again. His hand cocked back as Vernon prepared for the strike, before it launched like a missile towards the girl's small frame. But Rose never felt the blow come. She'd shut her eyes and heard the thump, a splash of something hot and wet splattering onto her face. Opening them in shock, Rose crumbled to her knees as she looked on at her now bleeding brother. Of course, Harry would step in front. He was her brother, he'd die before she was hurt.

Fate smiled. The boy was perfect.

"HARRY!" Rose screamed She tried to shake him awake with no luck. The gash was bleeding profusely from his brow. Rose realised then that the blood on her cheek was her brothers. Stained onto her face, a memorial to his love for her. "STOP IT! STOP IT! Leave him alone!"

Vernon smiled maliciously as he reared the skillet back for another hit. 'This is it'Rose thought, 'The freaks die tonight'. The crash of the front door falling to the ground stopped Vernon for only a moment. Petunia's scream was not what stopped him thought, it was the bolt of red lightning that hit him in the back and made the skillet fly into the wall that stopped him. An old man strode into the room, his face a blaze of fury as he held a wooden stick in his hand. Midnight blue robes that someone from a children's book would wear, topped with a witch's hat with golden stars. Rose must've been hit hard, she must be dead. Maybe she'd left the gas on at the stove?

The stillness in the room was broken by the man's voice. So icy and powerful that electric lights would've flicked, let alone candles. "I trusted you. The two of you. To do these two children right, to raise them and love them. Instead, you almost murder them in cold blood." The man crossed the room to stand in front of Rose and Harry.

"Obviously I was a fool to believe that any of you would be willing to change."

OAPAAP OAPAAP OAPAAP OAPAAP OAPAAP OAPAAP

Albus Dumbledore sat at his desk, a hum on his breath as he went through the latest reports on Niffler numbers. The little creatures seemed to be breeding out of control, all the spare gold that was hanging around these days. Dumbledore chuckled to himself as he thought of a couple of richer names which deserved to have a Niffler or two thrown into their vaults.

A familiar shrill chime sounded throughout the room. Fear and cold self-hatred spread throughout Dumbledore's body. He knew that sound. He'd heard it all too often. He prayed that it went away soon, it looked like another sleepless night for him. 'For the greater good' echoed in the back of his mind, and for a moment he actually believed it, until he remembered. And then another shrill chime echoed throughout the room. One he'd feared hearing for the last 10 years. He acted without thought, leaping to his feet and running towards the window of his office. He hoped he remembered the charm as he quickly vanished the stain glass window and jumped out.

A few seconds of free falling was enough time for Dumbledore to remember the incantation and wand movement he needed. In a flash of bright light, that man was literally flying through the air, a shining bright light in the dark night, like a comet streaming past Earth. He waited until the walls of stone were under him before he landed, twisting himself before he vanished with a pop. The memory was as strong as it was 10 years ago. It didn't matter that every single house along the road was the same, it was who was inside that mattered. The children that he failed. The children that he would be punished for until his last breath.

Fate's anger rumbled in the darkness.

The door was blown apart with a simple spell, one that Dumbledore didn't even need to say. The next spell was even easier. Red shot from his wand, the stick purring in satisfaction and hunger as another enemy was defeated. The woman shrieked and the man looked aghast, but they didn't matter, all that mattered was the two children on the floor. His words were icy and hard, a testament to his power.

"Obviously I was a fool to believe that any of you would be willing to change. Hence why I shall be taking the children with me tonight."

Dumbledore would've thought there would be less argument, and yet Vernon still stuttered, angered. "Now just wait a moment, I expect compensation after everything we've done for these two! We've fed them, given them clothes, put a roof over their head!"

The man turned to face Vernon, fixing him with a steely glare. "If you expect me to believe the measly food and water that you've given these two, plus the cupboard you call a room, are adequate, then you Vernon Dursley are a bigger fool then I!"

Dumbledore looked down at the small boy and girl at his feet. Lily stood over a bleeding James, her eyes full of tears, James' blood splattered on her face. 'No…not Lily and James…Harry and Rose'. "Miss Potter, if you'd please come with me. I'll take care of you brother." Rose didn't argue. She knew what happened when she argued. That and she was still too shell shocked.

And with that, the man strode from the kitchen with an unconscious Harry in his arms. The Dursleys were left stuttering as their niece and nephew walked out of their lives, seemingly forever. Dumbledore thought that was too lenient. He'd be back, there was any number of charms he could perform to make their lives hell.

Rose thought they made an odd group as they travelled out to the road. Her mind was still a daze, she could've sworn she'd been hit. "You must have many questions Miss Potter, but they shall have to wait for now. I suppose introductions are required however?" The man was talking to Rose.

"That would be rather useful, sir." Rose nodded. Rose knew how to be respectful.

Dumbledore saw through the respect. Through to the pain and hurt. "My name is Professor Albus Dumbledore." Dumbledore introduced himself, "And for many years now, I have watched and waited to see if your relatives would shape up. It appears that my waiting was all for naught."

For the first time in her life, anger and hatred flared up in Rose's body. "You mean to say that you've been watching Harry and I whilst we were abused, starved and treated with utter contempt!"

"It is my deepest regret that I must confirm your beliefs, however I did so with a reason which shall be explained once we find ourselves somewhere safe." Dumbledore needed her compliance, "Now, if you could please just trust me for one moment, and take hold of my arm, we shall go somewhere safe from your Aunt and Uncle."

Nodding her head slightly, Rose took Albus' arm with her dainty hand and held on for dear life as she suddenly found herself being what felt like being squeezed into a tube. Stumbling to a halt, Rose had to hold back the bile that was rising in her throat after taking such a journey. The bruises on her body ached and her wet knickers and skirt chaffed against her legs. After regaining her composure, Rose looked up to see that instead of being outside of number 4 Privet Drive, she found herself looking upon a large country house.

"Professor, where are we?" Rose asked, almost afraid to.

Taking a few great strides up to the front door, Albus turned to the youngest Potter and smiled. "This, Miss Potter, is the home of your Grandparents."

Rose stopped for a moment and just stared. A range of emotions were flowing through her. Rage mixed with relief. Even fear reared its ugly head again. Albus knocked on the door of the home in front of them, the bangs of the knocker echoing throughout the twilight hour. It only took a moment before a woman with bright auburn hair, speckled with grey, came and answered the door.

"Professor Dumbledore, it's been many years, what do I owe the pleasure?" The woman asked. The smile didn't quite reach her eyes. The man had come to take something else from her.

"My dear Juniper, could I perhaps come inside? There is much to discuss." Albus gave her a tight smile.

Nodding her head, the woman called Juniper moved to the side, until she noticed the two children accompanying Albus.

"Professor, is that…are these my daughters' babies?" Juniper asked, her voice breaking with emotion.

Giving Juniper a slow nod, Albus pushed his way past her, and into the sitting room where he placed Harry onto a burgundy coloured couch. Albus' intrusion did not go unnoticed, as an older man with greying light chocolate brown hair came striding into the room.

"What's all the commotion about?" spying Albus and the Potters, the man promptly stopped and let his mouth fall to the floor. "Dumbledore, what's going on here?"

"Alexander, there are two people I think you'd like to meet." Albus said pointing to the Potter siblings.

The man named Alexander, Rose could only assume he was her grandfather, looked livid as he stared at Albus with a deathly glare. "10 years too fucking late I might add! Look at these two, you know what they look like? They look like the kids we took out of Belsen! Filthy, beaten, malnourished kids. You knew what my daughter and that bastard of a husband of hers would do to them, but no, you had to place them there! I should wring your neck!"

"Alexander please, my intentions were to save the two children from what was left of Voldemort's followers, you know this!" Albus tried to reason.

"I don't care for your petty excuses Albus, you denied my grandchildren a childhood, you should have left them here, with us!"

By this stage, Juniper had regained her composure and came to stand by her husband. She didn't need her husband becoming a murderer. "Alex, we need to hear what Albus has to say before we jump to conclusions." Juniper said, taking a look at her grandchildren, Rose lying next to her brother as he laid their unmoving. "Not just for ourselves, but also for these two."

Alex nodded his head, his anger washing off as his soulmate calmed him. "Alright, you've got one chance Albus, explain."

Dumbledore nodded his head as he turned to Harry, "I think that this is a conversation for all of us, so please, let me wake Harry up before we continue."

The older couple gave nods of consent as Dumbledore turned to the two Potters. "Miss Potter, I need to wake your brother, is that alright by you?"

Rose watched the man named Dumbledore carefully. Her anger had subsided but fear was still snaking its way through her body. 'If he hurts him, I'll bite his leg off, then kill myself. Better to be together in death then parted in life'. A decision was made as Rose nodded her head stiffly, the motion so small that Dumbledore barely registered it. Taking out his wand, Dumbledore casted an intricate spell, making Harry's body light up in different places all over, causing the old man to frown deeply. Shaking his head, Dumbledore used his wand once more to cast 'revenerate' onto Harry.

Sitting up with a start, Harry took in his surroundings quickly before his eyes came to Rose. Harry quickly grabbed hold of his sister and took her face in his hands, "Are you alright? He didn't hit you, did he?"

Rose shook her head as fresh tears came to her eyes, "I'm alright, you took the blow for me." Rose said the last part with her eyes downturned to the floor. 'I almost killed him.'

"And I would gladly do so again." Harry said as he laid a gentle kiss to his sister's brow.

A voice clearing their throat brought Harry's attention back to where he was. A new fear sprung up within him, but he knew he had to be strong for his sister. "Ah, right, where are we?"

Fate reared his head and rejoiced. The die had been cast, and he'd loaded them.
