Chapter 1: Ancient Spells

Harry came down stairs some hours later, more then a little confused. Not only was the dream a point for wondering, but it was also nearly midday. Why hadn't Aunt Petunia awaken him? She always woke him, if only to make him do chores!

With a slight amount of hesitation, he entered the kitchen, to find his Aunt at work, as usual.

Upon hearing the door shut, she spun around. "O-oh! Good morning, Harry." She offered a tentative smile, "Did you sleep well?"

"Well enough..." Harry replied, frowning. What was going on? Had the Headmaster paid a visit that he wasn't aware of?

"That's good." Aunt Petunia replied, after a moment's silence, "There's some fruit in the fridge, for breakfast."

Still frowning slightly, Harry nodded, walking over to the fridge. "Thank you." He said, taking out the single, nearly overflowing plate of fruit salad, and taking it over to the table to begin eating.

"Harry?"

He looked up, swallowing a piece of melon in the process. "Yes, Aunt Petunia?"

"Would you mind going into town with me a bit, today? ... I noticed you're needing new clothes..."

"Certainly..." the young wizard replied slowly, while at the same wondering, 'What in Merlin's name is going on?!' deciding on finding out, he asked. "Aunt Petunia? ... Has something happened?"

"Pardon? ..." She replied turning back to him from wiping down the already spotless counter. "O-oh... well... no... Nothing really happened... I merely happened to remember something last night..."

"Remember something?" Harry blinked, "What?"

"H-Harry..." she sighed, "Do you remember anything of when you were younger...with your parents?"

"No... Not really..." Harry replied slowly, now more curious than ever. "Why? ... Did you remember something about my Mum and Dad?"

"You could say that..." After a pause, Aunt Petunia threw down the cloth she had been wiping the counter with, "Wait here." She said, before walking into the sitting room. She came back a moment later, holding what appeared to be one of the older photo albums... one that evidently hadn't been touched in years. She was looking through it when she stopped next to him, seeming to find what she was looking for, she set the book on the table. "That is what I remembered."

Harry looked down at the page curiously, and was surprised to see that it was a very familiar photo. It was his favorite picture of his mother and father, where they were holding him and staring into the frame, smiling. But there was something different about it... something besides the fact that it obviously wasn't enchanted to move like most Wizarding photos. 'It looks just like the painting I saw in my dream last night!' he realized with a start. "Who... who's that?" he asked, pointing shakily to the smiling six-year-old girl in the picture.

"That..." his Aunt replied slowly, with what Harry was surprised to note as affection in her voice. "...is your sister."

Now, one might think to blink, gasp, shout, or scream upon such an astonishing finding as this.

Harry Potter, however, chose the other option.

He fainted.

"Something wrong, Milady?" a hesitant voice inquired.

The young raven-haired woman did not turn her slightly over-bright eyes from the view of the vast estate outside the large bay window to the small creature in the doorway of her office. "No, Ollie, nothings wrong."

"You be wanting something, Milady?" the anxious house-elf inquired.

"No, than– Yes, actually. Yes, I do. Wait here a moment, please." She replied, walking over to her desk.

"Yes, Milady."

The young lady smiled, shaking her head as she wrote a short note informing her commander that she would be taking a leave of absence for the summer. She shook her head, 'Well, she wanted me to take a vacation...' Signing the note, she rolled the parchment up and walked over to the doorway, handing it to the small creatures. "Please take this to Amelia Bones, at the Ministry. And make an appropriate copy for the Minister."

"Yes, Milady!" the house elf replied, vanishing in a flash of pale blue light.

And then, with a small smile, the young witch Disapparated.

*Knock* *Knock* *Knock*

Mrs. Dursley looked up from cleaning the coffee table, she sighed, rising to her feet and leaving the cleaning rag behind as she walked over to the door, sparing her nephew – who was still unconscious on the couch – a concerned glance.

Coming to the door, she forced a smile before opening it. "Good Mor...."

The young woman smiled warmly. "Good morning, Aunt Petunia... It's been a long time."

"Y-yes... it h-has...." Mrs. Dursley replied, taking a step back. "Won't you come in?"

"Thank you." She replied, stepping inside, and watching as her aunt closed the door behind her. "Is Harry here?"

"Y-yes, he is." Mrs. Dursley nodded toward the living room.

With a smile, the witch walked into the living room, her aunt trailing behind her. She blinked in surprise upon seeing the young wizard on the couch. "What happened?"

"He... fainted."

"Fainted? Why?"

"When I... revealed who you were... it was quite a shock to him..."

"Oh... I see..." she shook her head.

"Would you care for some tea?"

"Please."

A short time later, the pair sat on opposite ends of the coffee table, sipping herbal tea from plain mugs, occasionally glancing at the boy on the couch.

"So... how are you?" Aunt Petunia asked, trying to make conversation with a person she had not seen for in years, and one who had only been a child then, now a full grown woman.

"Quite well, thank you." Vivian replied neutrally. "And you?"

"Well enough, thank you."

"And how are Uncle Vernon and Cousin Dudley?"

"They're... fine..."

Vivian smiled, "Is something on your mind, Aunt Petunia? I realize that this must all seem rather strange..."

"Well, yes... where have you been the past fifteen years? And... Why did I..."

"Not remember my very existence until last night?"

"Y-yes..."

Vivian shook her head, "It's rather complicated, but you do deserve to hear the truth... I assume you know of Harry's history?"

"N-not really... some..."

"Really?" Vivian raised an eyebrow in elegant skepticism. "I would have thought Professor Dumbledore would have told you something... Well, I suppose I'll have to summarize that for you to... A moment though, Harry should probably hear this as well."

Aunt Petunia nodded in agreement, only blinking in surprise when a wand suddenly appeared in her niece's hand.

Smiling slightly, the witch pointed her wand at her little brother, "Ennervate."

Harry woke immediately, eyes widening slightly as he saw a wand pointed directly at him.

"Hello, Harry." Vivian smiled, slipping her wand back into her sleeve so quickly that one might doubt it had ever been removed from the holder on her lower arm.

"Who are you?" Harry demanded, slightly surprised at the good humor and warmth he saw in the witch's disturbingly familiar eyes...

Vivian raised an eyebrow, "I think you already know that, Harry, if you're willing to accept it."

"Accept what?" the young Gryffindor demanded.

"Harry...?"

Harry turned to meet his aunt's nervous sky blue eyes. "Yes, Aunt Petunia?" Then, he blinked as he realized the anomaly of the situation.... Here he was, the one angry about the fact that one of his kind being in the house, while it didn't seem to bother his aunt at all! In fact, she almost seemed... happy about it... if a little nervous... "Wait... What's going on?"

"Harry, this is your sister, Vivian."

Harry stared at both of them, before blinking and shaking his head, a confused expression crossing his face. "B-but... I don't have a sister..."

Vivian sighed, "Perhaps I should begin my explanation of why I haven't been around, then? It should clear a few things up."

"Please do." Aunt Petunia replied.

Harry nodded slowly, eyeing her wearily.

"Aunt Petunia has informed me that she needs some of the background information that I'm sure you are already quite familiar with Harry, so please, bear with me..." Vivian smiled slightly before continuing. "Fifteen years ago a dark wizard calling himself Lord Voldemort began trying to take over the Wizarding World, while annihilating as many Muggles as was possible in the process... Those are remembered as very dark times... mainly because no one knew whom to trust, because Voldemort was slowly bringing many over to his side. Some went to his side willingly, either from greed or simply out of desire to be on the winning side... Others were forced over, by threat of death or harm to their families, or the Imperius Curse...." Seeing her aunt's lack of comprehension, she explained, "The Imperius Curse is one of the three Unforgivable Curses. It causes the victim to be completely under the command of the spell's caster, they have to do whatever the caster wishes, there are few who can resist it, very few..." She sighed. "At the same time, it wasn't only Muggle-borns that were in danger... Purebloods were threatened as well. Anyone of high standing in the Wizarding World who might want join the Dark Lords forces, let alone those who already had, usually ended up dead. Almost all of the people who fought against him did as well..." Here, she offered a weary smile, "With me so far?"

Both nodded.

"Good," she continued. "As the forces of the light became more and more desperate, the Order of the Phoenix, originally founded by Merlin himself, was started once again by Professor Dumbledore... Now, while they wanted to save the Wizarding World, the members of the Order needed to protect themselves as well. So one of the members came up with a theory. They could hide the members' families, what they cared the most about, by casting a spell that would make Voldemort's forces quite literally forget about them."

"But," Harry interrupted, "I thought the Memory Charm had to be performed directly."

Vivian nodded, "It does, but this was not the Memory Charm we know of. It was a form of Ancient Magic, which a few members of the Order had been studying, in hopes of finding Voldemort's downfall... Now, many of the members of the Order were skeptical towards this method. It was Ancient Magic after all, which most people consider unpredictable... Nonetheless, they agreed to a test run. As it happens, the Potter family was of very high standing in the Wizarding World, and it was one of the few families that was openly associated with the Order of the Phoenix, and therefore one of Voldemort's primary targets. So, mother and father agreed to the trial. Precautions were taken, of course. The Order placed an incredible number of wards around the estate, and on it. Then, mother and father moved out to the town house, taking you," she nodded to Harry, "with them. They knew that the estate was one of the things that the spell would be concealing, and they didn't want to risk it harming you..."

After a moments silence, Harry asked, "What happened?"

"I can't say I know precisely... I can only tell you what my tutors told me and the theory's we've come up with over the years..." Vivian sighed, "The most logical explanation is that the Order lost control of the spell... and it's the only thing that explains the results... No one outside of the estate remembered the estate or those on it, or anything connected to it... Mother and Father thought that the townhouse on Godric's Hollow was their actual home... And they forgot all about me..." A single tear slipped down her pale cheek.

Aunt Petunia rose to her feet and after a moment's hesitation walked over and embraced her melancholy niece. "It wasn't something they wanted to happen, love. I know for a fact that they loved you very much. Never doubt that..."

Vivian nodded, bring a hand up and wiping away any other tears before they could fall. "I know..." she glanced over at her brother, offering him a slightly saddened smile while her aunt returned to the chair across from her.

Harry was staring at her in shock. He didn't have any trouble believing her, everything she said made too much sense and felt too right for it to be a lie... What he had trouble believing was that a member of his immediate family was sitting in the Dursley's living room... Being comforted by his aunt, no less. He shook his head, "But... Why do we remember now?"

Vivian smiled slightly. "That's my doing, I'm afraid... You see, once they realized what had happened, my tutors on the estate began looking for ways to fix it. A few years ago, we finally found a way to do so. We put spells in place that began to wear away at the spell... or would have done so... The final requirement on them was the someone had to at least start recognizing it... So it began the day Hagrid delivered you your admission letter, Harry."

"What?" Harry blinked, "What'd you mean?"

"When you realized that you were a wizard, you were one step closer to me... Then, in your third year, when you started hearing Mother and Father's last moments, because of the Dementors... And when you met the Marauders..."

"Well why didn't I remember you last summer?" Harry inquired.

Vivian shook her head, "It wasn't enough."

"Then what was?" the wizard demanded.

"Unfortunately," his sister sighed, "it was the Tri-Wizard Tournament, and it's resulting events that managed to break most of the spell..."

"Why?"

"Three schools participate in the Tri-Wizard Tournament, can you name them?"

"Of course," Harry nodded, "Hogwarts, Drumstrang, and Beauxbatons."

"Right," Vivian nodded, "The first reason was because you were meeting people from Beauxbatons, some of whom, knew me."

Harry blinked, "What?"

"You see," Vivian sighed, "I never received an admittance letter to Hogwarts, because of the spell, my name will undoubtedly appear on the admissions list for several years past when the whole of the spell finally wears out and the Wizarding World remembers my existence.... Therefore, instead of going to Hogwarts - which the spell simply would not allow - I went to Beauxbatons under the name of Vivien Potier. That is technically French for Vivian Potter, but because of my fluency in French – and a few well-placed charms from my tutors, no doubt – no one ever made the connection."

"So because you went to Beauxbatons, my meeting students from there helped break the spell?"

"Partially," Vivian nodded, "Although it wasn't really the students, though they undoubtedly helped... but Madame Maxime is actually the only person you met that actually knew me as a student... And Fleur was a student of mine.... Then of course Voldemort was brought back, with some of Mother's magic protecting him, which did further damage to the spells... And now Voldemort can sense the spell, he knows that he's forgetting something... As soon as he remembers, the entire Wizarding World will."

"Oh...."

"Umm... pardon me..." Mrs. Dursley bit her lip from her chair.

"Yes, Aunt Petunia?" Vivian asked, turning to her.

"What did the spell do to me?"

Vivian sighed once again, "Well, for one, it made you forget me, and just like with Mother and Father, who it adjusted to living without the manor, it adjusted you to your life as well, a life where I didn't exist. Therefore the happy times you had with my parents and I didn't exist either.... You see, you had met Uncle Vernon two years earlier, and stopped contacting us because he didn't want to have anything to do with us. Then when the spell hit you, you forgot that you weren't just pretending to dislike and distrust the Wizarding World, you actually though that was your own view on the matter."

"Y-yes," Aunt Petunia sniffed, a tear slipping down her cheek, "I remember now..." she sighed, shaking her head, "It's funny really..."

"What is?" Harry asked curiously, still not used to, but unquestionably preferring his aunt like this.

"The timing... I was actually considering leaving Vernon at the time, because I missed you all and I wanted to meet you, Harry." She shook her head, "Had it been cast a week later, everything could have been so different..."

~ * ~

The Hogwarts Professors were seated in the Headmasters office. Snape sat in an enervated silence. McGonagall was reading from the Daily Prophet, a look of disgust on her face. Trelawney was babbling about some prophecy of another. Flitwick and Hooch were discussing the last Quidditch match, while Sprout was reading from a book of garden remedies. They quieted down as the Headmaster himself entered.

Dumbledore smiled, "Well, it seems–"

Suddenly an orb on his desk released a burst of orange light.

They all turned to stare at it.

"What was that?" Snape inquired.

Dumbledore walked over to the desk, picking up the still orange orb, and frowning.

"Albus..." Professor McGonagall's eyes were wide. "Isn't that...?"

Dumbledore nodded, before turning his attention to the other – now curious – Professors. "This, is a ward auditor, set to watch over the wards I have placed on Mr. Potter's summer residence. Thankfully, since it is not red, we can assume Mr. Potter is in no immediate danger, but there is an unknown member of our world on the Dursley property..." he sighed, "For sanity's sake I shall go see who it is, if only to guarantee that the boy is safe..."

"I'll go with you, Albus." Professor McGonagall said, rising to her feet. "He is in Gryffindor, after all, and I'll worry myself to death sitting here."

"I will come too, sir." Madam Hooch said, also rising.

"Oh for Merlin's sake, why don't we all just go?" Snape snapped, "As it appears you all want to."

~ * ~

Vivian looked up, and blinked, "Oh dear..."

"What is it?" Harry asked, looking to his sister in concern.

"It seems I've overstayed my welcome."

"Oh, no!" Aunt Petunia gasped. "Please, you must stay at least a bit longer!"

"I would love to," Vivian sighed, "but I'm afraid you're going to have company rather soon... And I'm afraid that as long as the spell holds on them, I can't possibly explain why I am here."

"I don't understand," Aunt Petunia shook her head, "Who's coming?"

"Harry's teachers," the witch replied.

"Oh, that's right," Harry gasped, "I'm sorry, I'd forgotten." Turning to his aunt, he explained, "The Headmaster placed a bunch of protection wards on Privet Drive, so that Voldemort and his followers couldn't attack me here."

"Therefore, I must go." Vivian murmured, rising to her feet.

"Then we're going with you." Aunt Petunia replied, also rising.

"What?" Both Potters demanded.

"Harry would be better off with you anyhow, and I haven't seen you in years." Petunia murmured, meeting her niece's emerald eyes. "Plus," she sighed, "I can't stay here any more, it doesn't feel right... I would have left Vernon years ago if that spell hadn't made me forget I was intending too."

"But what about Dudley?" Harry asked.

Petunia shook her head, "He's his father son, I tried, but... He'd be better off with Vernon anyhow." She looked at her niece, "Please?"

Harry also met his sister's eyes, his own as hopeful as his aunts, if not more so.

Vivian sighed, "Very well, we have a small amount of time, do either of you have anything you want to take with you?"

Both nodded.

"My school stuff is in the cupboard under the stairs, and my owls up in my room." Harry replied, "I'll go get her, but the cupboard's locked, and–"

"I'll deal with that." Vivian interrupted, waving him off. She turned to her aunt as her brother ran upstairs, "Aunt Petunia?"

The blonde nodded, "I'll be back in a moment." She hurried up the stairs.

Vivian went to the cupboard under the stairs, and pointed her wand at it. "Alohomora."

Instantly, the door burst open, and she muttered something under her breath and waved her wand at the contents inside, which promptly shrunk and flew to her out stretched left hand. She dropped them in a pocket of her robe.

A moment later, Harry and Aunt Petunia came down, Harry carrying Hedwig and a few photo albums, their aunt struggling with a large suitcase.

Vivian waved her wand, muttering the same incantation once again, and the suitcase and photo albums flew to her left hand, shrinking along the way.

Harry and Petunia both blinked.

After a moment Petunia grinned slightly, "Handy, that."

Vivian nodded, "Ready to go?"

Both nodded.

"How are we going to leave without running into the Professors?" Harry asked.

Vivian smiled slightly, "We're going to use their own spells against them," she replied, "Dumbledore will undoubtedly lift the wards against Apparition so that he and the Professors can arrive here as quickly as is possibly. We can then simply leave by Apparating."

"But," Harry shook his head, "I don't know how to Apparate, and I thought it wasn't a good idea to be Apparated by another witch or wizard...."

"It usually isn't," Vivian shrugged, "But I happen to be very good at it. All I need you to do is trust me. Can you do that?"

Aunt Petunia nodded immediately. After a moment's hesitation, Harry did the same.

"Alright then," Vivian smiled, "Come here, please."

They quickly obliged, and the witch continued.

"Now, Harry, just to make this a little easier, I want you to hold on to your owl's cage, very tightly, and hold on to Aunt Petunia's hand. Aunt Petunia, you hold onto Harry's hand and onto my left hand."

Both immediately did so, and waited for something to happen.

Harry suddenly remembered something, "Umm... Vivian?"

"Yes?"

"I think I should warn you, I don't react well to Floo Powder and I don't like Portkey's very much either." He told her nervously.

She smiled, "Don't worry, Apparating isn't anything like either of those, the only thing they have in common is that they're means of travel."

Harry returned a relieved smile.

As an after thought, she added, "And I have to agree, Flooing is horrible, isn't it?"

Harry nodded.

Suddenly, Vivian blinked.

And they were gone.

~ * ~

"Albus, shouldn't the Ministry workers be here, too?" Professor McGonagall asked, "I mean, didn't the Minister have the Aurors put some of their detectors and wards up around here?"

"To my knowledge, yes, he did." Dumbledore replied, as he and the other Professors hurried up the walkway of number 4 Privet Drive. "I'll have to ask him." Reaching the door, he knocked quickly. Upon receiving no response after the second knock, he pointed his wand at the door, "Alohomora," and the door immediately burst open.

The Professors hurried inside, Hagrid closing the door behind them.

After a rapid search, it became obvious that it was quite empty.

The teachers gathered in the Dursley's living room, not sparing a glance for the empty mugs on the coffee table.

"Headmaster!"

They followed Professor Flitwick's call into the hallway, to find him standing by the kitchen door, his wand pointed at the floor.

"Whoever they were, they Apparated out from here." He shook his head, "The must be very good, sir. Not only did they know when the Orders' wards were down – you just lowered them a few moments ago, after all – but they took two people with them... judging from these signatures. They're powerful, and Mr. Potter was one of the people to go with them... the other was a Muggle."

"But," McGonagall shook her head, "I thought you had to trust the person transporting you in order for them to Apparate with you correctly?"

"Not necessarily," Snape murmured, "Some are magically strong enough and adapt enough with that particular charm to perform it without the consent of the extra passenger, or in this case, passengers."

Flitwick nodded, "That is correct."

Dumbledore sighed, "Well, it seems we'll have to be talking to the Ministry sooner rather than later... Severus, do you know if...?"

"To my knowledge," Snape replied, "This is not the Dark Lord's work, but I can't be sure."

"Why not?" Hooch demanded, "You are a member of his inner circle!"

Snape smiled coldly, "A member of the inner circle, yes, but not the trusted inner circle." Raising an eyebrow, he murmured, "Now, perhaps we should inform the Ministry that the famous Harry Potter has gone missing?"



End of Chapter 1.

AN: Well, that's it for Chapter 1! What'd you think? I'd like to thank Moonlight Trickster and Evil Bunny of Doom for reviewing, and for your complements. I'm sorry for the wait.
