Chapter 1

Harry Potter was not a loved child, he knew this; he wasn't even liked or tolerated. He was a Freak according to his relatives, a liar according to many others. He knew it was his family who were the liars though, he was smart and paid attention in class. He knew that the world was not what his Aunt and Uncle told him, that there were people out there with amazing abilities. Mutants some were called - and Harry did wonder if he was one - but he wasn't sure. He'd never met one as far as he knew but it didn't feel right, from what little his teachers and books said, they had one power, but he'd done a few different things, like turning the teacher's hair blue and appearing on the roof when chased. If mutants existed maybe other things did…like magic, his family were adamant it didn't exist which meant maybe it did.

His relatives did their best to ignore and belittle him which made his accompanying them to the British Museum a very odd occurrence indeed. However, Mrs Figg was out of town and there was no one else to watch him. Plus, the fancy clients had seen him and would ask too many questions if he'd been left behind. Fancy clients were the only reason any member of the Dursley Family was stepping foot in the museum. Dudley hated places like this, Uncle Vernon didn't like anything that didn't fit his worldview, which meant a lot of the things in here, and Aunt Petunia just looked down her nose at all the tourists while smiling at the clients.

Harry himself found the museum utterly fascinating, there was so much to see and do! If only he wasn't having to stay right beside Aunt Petunia. He wished he had days to explore but he doubted he'd ever be allowed to come back. It was all so fascinating, better than school! They wandered into an exhibition from the time of Knights since there was armour hung up. He was good at reading, but the signs were small and complicated, making it hard to read even with his glasses. He was only six and a half, after all.

"Enjoying yourself?"

Harry looked up at the nice lady and nodded. "Yes ma'am." He had to be very polite to clients and only speak if spoken to.

"What little boy doesn't like Knights and Castles Mary?" he asked his wife, glancing at the small - too small - boy. There was something off here, but he didn't know what. He didn't like what his suspicions were showing, but it wouldn't hurt to send in an anonymous tip to child services. "Why don't you boys go have fun at the discovery table," Alec offered.

"Go along boys, have fun." Aunt Petunia smiled tightly, and Harry knew he'd be paying for this later, but for now, he got to go play.

The lady behind the counter smiled and began explaining about the different items, boring Dudley but Harry was fascinated. His eyes widened as he saw a beautiful dagger. He hesitantly reached out and touched it. "You can pick it up, it's real but it must have been damaged over the years as it won't come free of the sheath no matter how hard we try."

Harry hesitantly reached out and picked it up, turning it in his hands. It was so light, and the sheath looked pretty new for something so old. And then Dudley grabbed it off him and Harry shifted away.

,,,,,,,,,,,,,,,

A jolt went through him, something he hadn't felt in so long that it actually stirred him into consciousness. It was power, untapped potential, a Mage and a powerful one too. He ignored being touched by another, this one wasn't worthy of his attention; tainted by greed and laziness. Over the centuries he'd passed through many hands, none worthy. This one though…this one had potential, if he was willing to risk it. He could re-join the world, have a bearer again. Or he could stay as he was and let the world pass him by, it was tempting. He'd already given so much to the protection of the world; didn't he deserve to rest? In the end he couldn't sit by and reached out for the touch of magic, ever so gently twining himself into it.

As Harry and Dudley left the museum a sheathed dagger glowed and then shimmered away, leaving nothing behind.

,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,

Harry sat in his cupboard, arms wrapped around his knees even as he bit his lip, he would not cry out. He'd paid for the clients being nice to him, just like he'd known he would. Everything hurt! Why was he such a Freak? He just wanted to be a normal boy with friends! Finally, he crawled onto his mattress and tried to sleep, closing his eyes.

,,,,,,,,,,,

He observed the nightmares for a while before reaching out to the child. He was young to bond with, but it was obvious the child needed support and training. He had never had a Mage as Bearer before, but he had known many over the millennia; he knew how they trained and what many of their skills were. The child, Harry, was old enough to begin gentle training. And so, he soothed the nightmares, pulling the boy into his mindscape, his soul.

,,,,,,,,,,,,,,

Harry blinked and looked around in confusion as he found himself standing in a beautiful field of flowers. A closer look showed many of the flowers were damaged, the trees withered, and he shivered. And then he saw him, a man standing beneath a tree. Harry took a step back, scared, but then the man smiled gently at him. "Who are you? Where…?"

"I am Excali'an of Atlantis and you are Harry Potter."

"Yes sir." Harry agreed politely, he was still recovering from his Uncle's displeasure, he didn't want to make this man angry at him as well.

"Perhaps there is a name you will recognise better; I am also called Excalibur." He moved slowly closer, not wanting to scare his Bearer.

Harry's face scrunched up in concentration. "Wasn't that a sword? And make believe?"

"Once I was a man, a Knight. I fought many battles to protect my home but, eventually, I fell in battle. Ancient magics and my desire to protect forged the sword Excalibur from my very soul." He bit back a chuckle as the boy blinked, trying to follow the explanation. "I am a sword now Harry, but many years ago I was a man."

"Okay." That was easier to make sense of but how could a man become a sword? Magic wasn't real, according to his family. He looked at the man, he was really tall and had dark blue hair and light blue eyes. Aunt Petunia would not like that, she didn't like 'unnatural' colours and who had blue hair? Well, other than his teacher that time but that had been an accident. Maybe magic really was real and that was why his family always insisted it wasn't.

"You wanted to know where we are?" Excali'an sat on the grass, legs crossed, and Harry slowly moved closer, sitting on his knees opposite the strange man. "We are inside your mind Harry."

"My mind?"

"Yes. This is your mindscape, also referred to by some as your soul, though that isn't fully correct."

"But if this is mine then why are you here?" Was he possessed? He'd heard of that the times he'd been dragged to church by his Aunt, his Uncle had even suggested an exorcism once and that had been very scary.

"I am a weapon, a tool, and to be useful someone has to use me. I have been sealed away since King Arthur died but when you picked me up, I found someone worthy of being my Bearer." He also wasn't used to trying to explain things to a child, even a smart one.

"But I didn't touch a sword!" Harry denied.

"I am not always a sword, sometimes it is not easy to carry one. I can also become a dagger."

"The one stuck in the sheath?" Green eyes widened in shock.

"Yes."

"Oh," Harry whispered even as the dagger appeared in Excali'an's hands. He held it out and Harry hesitated but then closed his hand around the handle and then he gasped, eyes flashing blue. "Wow."

"I am yours to Bear young Mage. My power is yours to wield for as long as you live." He stated formally even as the dagger briefly morphed into a sword. "Of course, while you are so young wielding my true form will not be possible." He chuckled at the sight Harry made holding a full-sized sword for a few seconds. He would need to grow a lot to wield him properly. "It is time for you to sleep Harry, we can speak more when you wake."

"But I am asleep?" Harry yawned, suddenly tired. Excali'an gently pulled him close, running his fingers through short dark hair and Harry drifted off into a deeper, dreamless sleep. As his Bearer slept, he began a full investigation of the boy and was not at all pleased with what he found. Things would have to change. He wondered if Emrys was still around, he would make a good teacher for the child but even if he was, Harry's memories showed a world population beyond what they had ever dreamed! Even at the height of Avalon's power they had never risen above several hundred million, and now there were billions of people! But apparently, they were all human, what had happened to the other races? There seemed to be no mention of those from other worlds either, he had hoped by now contact would have been re-established with at least their closest neighbours. He had much to learn of this modern world and limited time to do so, he had to keep his Bearer safe, but he also had a duty to the world. The next Convergence was likely approaching a world which had no defences against it.

There was something he could do now to improve Harry's life. The poor boy was borderline malnourished, his growth stunted, his eyesight was atrocious and numerous other issues were present. Perhaps he could jump start things for him. At the moment eyesight was the most important so he went to work, nudging things here and there. He wasn't a Mage, but he was a Soul Weapon and his Bearer was a Mage so one of those nudges was to the boys' magic, the tricks he knew would help his sight, adding magic to the mix would hopefully fix it. Those 'glasses' things would be a major liability in many situations. And without access to Avalon and the technology there, this was the best he could do.

,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,

Harry woke slowly and blinked up at the ceiling of his cupboard. It was weird but…. was it a little less fuzzy today? He winced as Dudley jumped down every stair, making said ceiling shake and drop dust on him. He sat up and pulled on the cleanest t-shirt he had and then his glasses, his hair was a lost cause. He waited for the door to be unlocked and then went to work making breakfast for them. His stomach growled, he was hungrier than normal, but he knew better than to expect anything he made, especially after last night. Though, he wasn't as sore as usual which was nice. He would give anything to be able to escape, to live anywhere else but he knew it wouldn't happen.

Listening to his thoughts it was obvious the boy had forgotten his dream, not unusual for someone with no training. And the hunger was his fault, healing took energy, hopefully the child would be sent out to 'garden' or wander, and he could lead him to edible flora to tide him over. Thankfully after only two hours of chores he was kicked out of the house and wandered to the nearby deserted park. 'Harry,' he called softly, and the boy stiffened, looking around wildly.

"Who…" Harry asked aloud, he couldn't see anyone.

'Am I that easily forgotten little Mage?' he teased.

Harry froze, little mage? Who…. the weird dream…. "Excali'an?"

'Good guess. And you don't need to talk to speak with me, just think.'

'Like this?'

'Very good Harry, now let's see about finding something to eat.' He led Harry through the park, both relieved when they found some edible berries. 'Now your training begins.'

,,,,,,,,,,,,,,,,,,

For two weeks he'd gotten a glimpse of a normal life as he was moved into Dudley's second bedroom and given nice clothes plus food to eat. It confused him at first until two strangers appeared at the door to look over the house, especially Harry and his room. It didn't take long to work out they were Child Services, maybe the clients from the museum trip had called them? He knew better than to try and tell them the truth, no one ever believed, and it would be easier to get away from here one day than a strange place. The break was nice and Excali'an made the most of the influx of food to fuel the healing of Harry's body.

,,,,,,,,,,,,,,,,,,,,

Harry sat with his legs crossed hidden in the bushes, eyes closed and breathing deep. It had been a month since Excali'an had come to him and every day once he'd finished his chores he walked to the park for training. At night they trained in his mindscape, but he needed physical training too. A Knight had to have total control over mind and body and in his case his magic too. Lack of food made physical training hard as he simply didn't have the strength or stamina. It was hard, and he was starting younger than most initiates, but it was necessary for the plan. He barely allowed himself to believe the plan would work but if it did….no more Dursley's, no more slaving for a family that hated him. For the plan his magical training was the most important, it would be needed to succeed. He just wished he had somewhere to train without worrying about Dudley or his gang finding him. Harry Hunting was getting easier though, he was getting faster on his feet, not that he'd been slow before, and better at planning where to run.

,,,,,,,,,,,,,,,,,,,

Harry stood in the kitchen doorway, ignored for once as everyone was transfixed by the news on the tv. Footage from the accident at Chernobyl a few months ago was being played before showing people lying in hospital beds, bodies ravaged by radiation. Then there was an anti-mutant rally shown, the people demanding the area around the reactor be closed off in case it caused more mutants to be born. Excali'an agreed it was possible, radiation caused mutation, but would it be the kind that made 'mutants'. The footage showed fire spewing up into the air and Harry shivered at the sight, feeling Excali'an's shock and disgust. Apparently nuclear power was not something that should be played with, not at their current level of technology anyway.

,,,,,,,,,,,,,,,,,,,,

"Boy! Get the mail."

"Yes, Uncle." Harry obediently picked up the scattered letters and carried them to the table, placing them beside his uncle before he went back to finishing the meal. He plated up the eggs and bacon. He then went to work cleaning up, ignoring his stomach as he did so. His relatives left the table and he collected the plates, eating the scraps quickly before drinking from the tap. He was getting better at sneaking extra food wherever possible, but it was never enough to make him full and he refused to steal from a store. Not that he'd get away with that, everyone in the neighbourhood believed the lies the Dursley's told about him so he was watched like a hawk whenever he went into a store. He couldn't wait until he was gone, maybe he could make some friends, find people who liked him.

He sighed when he saw the list his Aunt had left for him before leaving to 'socialise'. It was the biggest he'd had in a long time and generally meant only one thing: Aunt Marge and Ripper. He shivered, he hated that dog. He felt a wash of concern and calm flow over him from Excali'an and relaxed into the feelings. He went to work as quickly as possible, wanting to get it all done so he could leave the house and get to training.

He picked up his Uncle's discarded morning paper and looked at one of the front-page notices since it was a business paper. Tony Stark heir to Stark Industries had graduated from MIT at the top of his class. He was only 16 so that was a big thing and it made Harry want to leave even more. What could he do if he didn't have to act dumb at school?

,,,,,,,,,,,,,,,,,,,,,,,,,,,,

Harry silently packed what little he owned before slipping from the cupboard to raid the kitchen, shoving food in the ratty bag. He waved his hand at the door and grinned when it clicked open. A few seconds later he was passing through the extremely weak wards that wouldn't stand up to a stiff breeze let alone a threat. Excali'an had not been impressed when they had detected them a few months ago, Harry's magic finally at the point where they could detect such things. The wards wrapped around Privet Drive, with number 4 at the centre and they were protective in nature. Blood wards that were held by him and Aunt Petunia which meant a Mage was involved. Neither of them knew anything about the Mages of this time, Excali'an had been dormant too long, the world had changed too much. Whoever had set the wards had ignored one important fact, blood wards needed more than just blood: they needed love and magic. Harry was the only Mage in the house, weakening the wards a lot, and there was no love in that house, there wasn't even acceptance. Without those two necessary ingredients, the wards were never going to be able to do much of anything. As he walked down the street, he felt the wards collapse totally due to him, he had never called that place home and now he was leaving, never to return and there was nothing to hold them up anymore. He stepped into an alley and closed his eyes, focusing on where he needed to go.

He reappeared within a stone structure even he recognised. He'd seen pictures at school, but they were nothing like being there. The stones towered over his head and he nearly swooned at the feeling of so much magic in the air and ground. Aside from the stone circle there was nothing left. Camelot was long gone, even the foundations were gone from under the ground. All that was left was Stonehenge, and hopefully the station beneath it. He walked into the centre of the circle, glad for the cover of night, as he knelt down and began marking out a smaller circle before looking up at the stars to get his bearings, he sat and began digging, grinning when he hit pay dirt. If they were still here, then the station had to be as well. How they had remained hidden he didn't know but obviously there was some sort of protection at work to keep the various archaeologists who had dug there from finding them. He found the small sealed compartment set within the metal ring and popped it open, small fingers easily slipping inside to set and then activate. He stood up and the Rings leapt up around him before he vanished in a flash of light.

The light faded, and the Rings dropped into the floor beneath him, leaving him in the dark. He didn't move though, wary of any defences as the lights slowly came on. A woman appeared before him, clothed in a flowing white gown with fiery red hair flowing in waves down her back and her violet eyes were narrowed on him. Harry bowed slightly to her, fighting the urge to bite his lip.

Morgana Le Fay stared at the child before her, at least this invader had some manners. Her usual method for dealing with such would not do this time, she was more than a simple program with no autonomy, she was an AI, a child of Atlantis, and she would not kill a child. Over the centuries since Camelot's fall, she had sent many a body out to sea through the pipes that allowed sea water in and out of the station. It was not something she enjoyed but she would not allow her domain to fall into the wrong hands. "What brings you here child?" she asked softly.

"Bringing an old soldier home, Lady Le Fay." Harry answered with a smile even as he summoned Excalibur's portable form to his hand.

Morgana stared at the dagger, she recognised the weapon instantly. How could she not? Excalibur…Excali'an…he had vanished when Arthur was slain in battle. How had he come to the child? And why bring him here? "Passcode."

Harry took a deep breath and slowly pronounced the code, not wanting to mess the language up. Ancient was not easy!

The codes were correct and the last update Excali'an would have had. She wanted to ask the boy to channel Excali'an's power, but he was too young, it was too dangerous at even a low level. The passcode was enough for her to give aide but in a limited fashion; he was young, she would wait and see how he grew before revealing everything. "How may I assist, Commander?"

"I need money and a way out of the country, and there's some stuff Excali'an said we need to be in a high magic area for."

"I can aid you in all three Commander. An amount of the Royal Treasury of Camelot was kept hidden and eventually through unknowing agents was placed within one of the first banks. That money has been invested well and has grown over the centuries. I can supply you with account numbers and the passcodes needed to access it. I am limited in my ability to interact with Earth systems. This is a listening station for the solar system after all."

Harry nodded, money was good. "Have any of the other bases survived? And the…solar defence net?" That was cool!

"I am not in contact with any other AI's. Unfortunately, the defence net has degraded even further than it was in Arthur's time. I have light contact with one scanning satellite out beyond what is called Pluto in this time. There is nothing to report on its scans, an occasional ship passes at the limit of its reach but nothing actually coming here since the 1980's when several Asgardian ships came into orbit, as did an unknown ship but it left after a brief time in the atmosphere."

"Asgardian?"

"The aliens, not the gods." She answered.

"Wow." Hey, he may be old for his age thanks to the Dursley's, but he was still just a kid and all this talk of gods and alien's thing was very exciting.

Morgana couldn't help being charmed by the child. He would be a powerful Mage once he was an adult and wielding Excalibur…well perhaps the time of the Terrans was coming again. Had Excali'an told him what being his wielder fully meant? She didn't think so, perhaps that would be one shock too many for such a young child.

,,,,,,,,,,,,,,,,,,,

Morgana smiled as she watched Harry work on his lessons. It had been a long time since she had any sort of company and especially someone she could teach. His knowledge of the Heavens would be unmatched by any modern astronomer when she was done with him. The skies were her domain after all.

,,,,,,,,,,,,,,,,,,,,

The people of Privet Drive watched in shock as Petunia and Vernon were led from the house in handcuffs. The word spread very quickly, their nephew hadn't been seen in over a month and they were being arrested on suspicion of killing the child. As the people began to talk, they slowly realised that the boy had not been what his family said he was. Without the threat of Dudley, the other children were willing to admit that it had been the Dursley boy who was responsible for what happened to them, not his cousin. The neighbourhood improved, everyone beginning to look out for the children and each other more, ashamed by what they had allowed to happen under their noses.

,,,,,,,,,,,,,,,,,,,,,

Albus walked into his office, relieved to be back at Hogwarts after his time in France. He smiled as he took everything in but then froze as he stared at a particular shelf before rushing from the Castle and apparating to Surrey. What he found confirmed his worst fears, the wards were gone as were the Dursley's and young Harry.

,,,,,,,,,,,,,,,,,,,,,,,,,,,,,

Harry sat under Morgana's careful watch in the main chamber of the station. It had never been designed to house actual personnel for any length of time, but Harry was only one person and a small child at that. The rations stored within had not deteriorated and the boy actually seemed to like them, which she found strange as she remembered many a soldier's complaints over the centuries when faced with rations. Nevertheless, she had plans to bring in actual food for him for the remainder of his stay…if he survived what was to come.

Harry closed his eyes, slipping into the mindscape to find Excali'an waiting for him. He was in full armour now, holding a sword, the same sword he took the form of in the real world. His armour wasn't what Harry had seen in history books, the metal was smooth, covering all vulnerable points, but it was also very nice to look at, with swirls of colour and runes. Harry looked around and then saw what they were here for, a writhing mass of darkness locked into a small corner. "That's it?" he asked nervously.

"Yes." He placed his hand on the boys' shoulder. "I am with you Harry; this must be done."

Harry nodded. He didn't understand how a soul could be cut into parts or how one could be in him, but he wanted it gone!

They moved closer to it and slowly it took the form of a tall young man with blood red eyes. He smirked at them. "Do you think you can defeat me again, Harry Potter?"

TBC…
