I don't own Harry Potter or Stargate.

Chapter 1

An aged wizard reminiscent of Dumbledore, but with more sensible robes, took up the cloak and wrapped it around his right arm as neatly as possible. Next he lay the stone atop the cloak on his arm before taking up the wand and tapping the stone. Harry got a sense that more would be revealed about the nature of the Hallows when he did. The instructions repeated with all the previous inflections...

Harry woke with a groan. He had first thought that the dreams were a symptom of the final battle at Hogwarts, but in the month after, it kept recurring. He had all three of the Hallows here at Grimwald Place and he knew he had to protect them, especially the wand.

The time after the battle had been busy. The ministry had offered him and his friends on the horcrux quest acceptable NEWTs and positions, except for Hermione. She had not taken that well and was resolved to finish her seventh year and accomplish outstanding scores and make it much harder to deny her without showing that they were just selfish bigots. The goblins had been much harder to smooth over but once they had explained the horcruxes, under confidentiality of course, there had been much more good will. Well, more good will than most thieves would ever get. Harry regained access to the Potter fortune but all fees were locked at 10 percent higher than anyone else but the three of them, including money changing to muggle currency.

The public had taken to calling him the Man-Who-Conquered and was dogging most of his steps when he went out, if he went out. He hoped that that would blow over for the most part if he gave it some time. His wizengamot seat was a new idea to him, and the current proxy was scared he would loose the seat as he had been appointed by Dumbledore and had never talked to Harry. He was expected to take his seat and play politics as the new defacto leader of the light because of his defeat of the latest 'dark lord' but he really did not have any idea of what he would be doing. He thought of toughing it out for a year and hiring Hermione to sit his seat for him, their values meshing for the most part.

Kingsley wanted him for the aurors and he really couldn't see himself really doing that job anymore either. He didn't want to spend his days and nights chasing Voldemort wannabes all over the British wizarding world. Ginny would not speak to him after dumping her in a noble attempt to protect her. He could see her point that he would never be able to giver her a normal relationship and she couldn't trust him not to dump her a gain if life got rough. He could obviously live without here so really didn't lover her enough to try.

He looked again at the Hallows sitting on the small table in the bedroom and made his decision. Crossing the floor and fidgeting with his glasses, he picked up the cloak and wrapped it around his arm. Thinking for a minute he picked up the wand and stone and made his way back the bed. Laying down, he set the ring down atop the cloak before using his left to tap the wand to it.

There was a flash of light and the wand dissapeared from his hand while the stone grew and broke the ruined setting it was encased in until it was large enough to just fit in his palm and situated on the back of his hand. From there there grew an interesting wooden looking metal substance that wrapped his arm to halfway to his elbow and settled as a finger less glove around his hand. He realized, no...was informed that that was what had happened to the wand. The cloak shrunk to fit under the entire thing and he could feel the tingle of the elder wand connecting to his magic.

His head began to fill with knowledge that he hadn't had before, that this was the armlet of Merlin Ambrosius and that there was much more to the history and traditions of the wizarding world than they all thought they knew. That they were all the descendants of the Lanteans fleeing Atlantis before a terrible enemy called the wraith and that magic was explainable by science just not science the muggles had reached the level of just yet.

He became dizzy as the download began in earnest and patted himself on the back as had thought to lay down instead of still be standing when he'd done what his dreams demanded. He knew now that this was an updated knowledge reppository and had been split up and hidden for ten-thousand years as the legend grew and it was a nanno-controller of lantean technological artifacts He knew that just about anyone else would die, eventually, if they had downloaded the entire thing, but his mind could handle it, however he would have a headache.

When the download was complete he realized that until he was ready and had more available resources, trinium and naquada along with other precious metals, he would need to keep most of this to himself. He needed to build a lantean computer core and constructor table and transporter and sensor and so much more if he was going to bring his people back to their rightful place. He would also need to draw and the lantean politics now imparted into his mind to guide the people to where they deeded to be to accept what he had to say. As the new leader of the light he had the pull to do so. But should he?

That question brought him pause and as he contemplated he could see where the technological know how could improve the wizarding world and ensure their continued hiding or bring back Atlantis but he would need zero point energy, magic, to power everything and he knew now on an instinctual level how to construct such things. He would need a potentia or three with his knowledge of Atlantis and the rate of decay of a potentia module that Atlantis couldn't have very long to stay hidden. The enemy couldn't be allowed to find her so this really did have to be done. His own knowledge of warfare from a muggle perspective, which he had been studying now and seeing how wrongly Dumbledore had fought and pushed the wizarding world to accept, saw that many things about the ship and fleet construction would have to change to be ready.

But first he needed materials to start building and knew that the wizarding world really didn't have an equivalent to junkyards so he would need to exchange money and take a horrible hit for a fee and somehow get the materials to Grimwald place. He contemplated for a moment before he realized that he could really use a house elf right about now but now that Dobby was dead there really wasn't any way for him to procure one. He didn't really trust Kreacher at the moment but there wasn't really any choice.

He rose from the bed and swayed a moment underneath his dizzying headache before checking the grounds for enough space to build.

The backyard of Grimwald Place was overgrown but large enough for his purposes. There was access to the yard from the street but it couldn't be seen by muggles so he would have to find a junkyard and hauling company run by squibs. He would need a constructor bot for sure and a constructor table but thank Merlin he could use transfiguration to reshape metals and materials now that he understood what he would need. First he needed to make crystals for control and information processing and a zero point generator to get himself by until he got his hands on the naquada to grow potentia modules. He would need trinium and naquada and iron and carbon and many other materials which he know the first two could not be had on earth so he would have to build a ship out of substandard Earth materials to find somewhere to obtain them. First for the crystals he would need carbon and silicon.

That would require a trip into London to get charcoal or coal then a transfiguration of the materials into the new molecular structure without changing what was. He went back inside to shower and prepare a minor disguise and ready himself to apparate out of the house to get the day done. He would need to find a computer store to get some parts like an empty computer case but he could use the silicon to construct his own monitors and screens. He wouldn't need wire but pure materials to transfigure his own. He needed to get started on a download capable computer terminal and thanked his ancestors for their obsession with perfecting their control of zero point energy but not that they had gotten hooked on the term 'magic'.

Getting ready hadn't taken long and he remembered that Kreacher was still in the house so called him out.

"Nasty half-blood master bees calling Kreacher?" the elf sneered.

"You will make the back yard presentable today. I have a project that I want to work on and I am going to need that space soon."

"Kreacher will do as the nasty half-blood says." with that final sneer the elf was gone.

"I could really use a new elf." Harry thought aloud.

With that done he was ready to go and Gringots was his destination.

Gringotts was busy with patrons that almost turned as one when he came in. The goblins however were not as pleased. They had forgiven him but didn't trust him anymore and he could Griphook behind the counter frown as he saw him..at least he thought it was a frown.

"Harry, how are you doing?"he turned to the voice to see Padma Patill and an older Indian gentleman approaching. Padma was wearing what Harry guessed was a traditional sarong like dress not dissimilar from what she had worn to the yule ball. It was orange and gold and made her brown eyes stand out. Her father was wearing a males version of the same and wore a slightly condescending look.

"Oh, hey Padma. I'm doing well enough I suppose." he waved off with his right hand which caught her attention.

"This is my father Suva. Dad this is my old classmate Harry Potter." she introduced, the eyes of her and her father locked on Harry's arm ornament. Catching their stares he blushed a little and responded to the unspoken question.

"Nice to meet you sir. This is part of the new project I am starting. How to bring technology into the wizarding world." Her father snorted.

"Muggle technology doesn't work around magic and no one has been able to make it work for that matter. You really aren't going to get anywhere with it, and I would think Hogwarts taught you that by now." he said patiently, as if talking to a small child.

"Daddy! No need to be rude. I'm sure he has a new approach, right Harry?" she prompted eagerly and hoping that he really did. Harry could tell that the feeling was real and knew that if he played his cards right he would have an ally in Padma.

"Yes, I have a new approach. Why try to force muggle things to work around magic when we can make things that operate using magic. We already do this so why don't we make computers and such that work on magic. Why don't we have muggle conveniences that work on magic. I know we have better transportation but we don't have things like movies, that is moving pictures that can capture a whole event and not just a few seconds. I have a way and I am about to start investing the future for as long as the goblins will deal with me." he said, motioning toward the counter where Griphook was glowering at him. He began to move toward the open counter as no one really wanted to deal with a glowering goblin. Padma and her somewhat reluctant father followed and a small crowd began to gravitate.

"I didn't know you were an enchanter Harry. You didn't take arithmancy or runes." she prodded.

"You're right that I didn't but I don't think I will need it. I'm not trying to make magic do things it doesn't want to do naturally but instead trying to make it do what it already wants to do and that is flow. The flow of magic agitates the quantum state of materials and with the right materials in the correct formats and placements will respond to the flow of energy."

"Quantum state?"

"It may help if you think of it as absolute properties of the base material." he responded as they reached the counter. Griphook growled.

"How can Gringotts help you today thief?" Griphook gruffed. Oh well, smoothed over not forgiven. His small group frowned but said nothing.

"Hello Griphook."he said drawing a surprised but unhappy expression. "I need to withdraw some galleons and change them to pounds today. Would that be possible or would I have to come by another time."

"No we can do this now and I couldn't help but overhear your conversation. Will this new business venture of yours be producing new funds. As your account manager, dead end job it now is, you could use some new income over the silent partnership with the Wizarding Wheezes joke shop. You no longer have interests in goblin investments." his tone was surly indeed.

"Yes that is the plan. The first will do calculations faster than any arithmancer on the planet and without errors unless the error is in the original equations. The other may change travel for the wizarding world. Imagine no more port key sickness."

"And, thief, would this new travel be able to get through goblin wards? Trying for a second attempt?" Griphook growled.

"No. The goblin nation will get what will block it free of charge." Harry quickly added.

"Good. Key?" already tired of the conversation.

"Harry, do you mind if I hang out with you for a while...I'm finding this idea of yours fascinating. If you're funding and running this you may need some kind of help and I know that Hermione will be in Hogwarts so..." she looked between her father and Harry with pleading eyes. Her father didn't look completely convinced but he nodded. Harry wasn't sure but he could use the extra pair of hands but didn't like that she would see how the goblins would treat him.

"Okay Padma. And I'll try to explain my ideas while we shop. Oddly enough your clothing won't raise too many eyebrows in London."

"Whats odd about it?" raised eyebrows from both of them this time.

"I'm just saying that if you were wearing traditional wizarding robes I would have to say no." he scrambled.

"Yes, all very entertaining, but if you could follow me please?" Griphook was getting impatient.

Padma gave a quick goodbye nod to her father who told her in Hindi to be home by eight and the two of them were off. The trip down to the vault was uneventful and the money changing was painful, with reminders that he was a thief to the goblin nation and he would forever have to deal with the unfairness or keep his own money...for a fifty percent withdrawal fee.

Padma found the purchases he made confusing and his descriptions required a background that she just did not have. However it was still early when they arrived at Grimwald Place and it was time to get to work.

Breaking out the coal he'd purchased on the trip and dipping into the sand bag he made a small pile of materials and held his new ornament over them whispering the incantation for focus. He didn't really need the incantation anymore as the knowledge to do what he was planning had been in the download as well but it didn't hurt. The material slowly came apart and began to reassemble into the new control and power crystals he would need and the computer case that Padma had carried was set to the side waiting for what he would need it for. The crystals took shape one at at time with him chanting out the incantation for each one as they first finished.

Soon he had enough for what he was planning and got to work on the case. This transfiguration was much easier because molecular deconstruction wasn't required just a basic shape change while leaving the main material unaffected. Padma asked questions all throughout the process and now that she could see the finished product coming together she could finally see what he had been trying to describe to her. It was late afternoon by the time the computer was finished with a glass display and silicon crystal input station along with a magic crystal power core, a small substandard potentia that was the hardest crystal to grow and the largest crystal of that type that could be stably made.

Once all the pieces were arranged he touched the activated project with his ornamented hand, the screen only showing that it was ready for programming and dumped on a basic Lantean operating system. It was cheating and he knew it but he really didn't want to spend the next several years building the programming from scratch when he could directly program it in this way.

Now that it had an operating system he could store at least some of the knowledge he had in the repository on his arm and in his head in the storage crystals. Again he wished Earth had access to naquada and trinium and that he had access to much more material but this would have to do. He began to pour on information on transporters and star ship designs programs from the ancient repository and lists of materials and design limitations for an Earth material ship. He would need a scanner and full sensor suite and of course a cloaking device and he mentioned all of this to Padma.

"So you're saying that this thing can do the calculations to build and deconstruct anything from more of itself to spells and this is just the beginning..." she looked at his affirmative nod and made a decision. "If you're going to make more of these then you are going to need an assistant...a better supply line, better quality materials and so much more...if you're paying then I'm in, but you're going to have to teach me to use it so I can write a manual."

He could see her point and it helped that she was easy on the eyes as well. He of course didn't say the last part out loud. Smirking he began picked up the control crystals he'd made early, the spares she had thought, and began on another project, not really slowing down for the day. An hour later he had a substandard constructor table. Running one of the computer wires that he'd transfigured for the interface he plugged it into the computer with an hour to spare for her visit before dumping the rest of the raw materials onto the table. Back at the computer he pulled up the plans for the sensor and sent the build command.

The table hummed and slowly the pile began to diminish while above it a sensor array began to form. Being made from softer substandard materials it would only see about six light years away from here but it would be enough for his purposes. When it was finally complete Padma turned to him.

"Ok. Where does all of this knowledge come from. You suddenly know how to do all of this and make a table that automatically transfigures multiple things at once from raw materials and a , what did you call it ….computer and magic crystals and the thing on your hand seems to have all sorts of information in it...what's going on. My helping isn't contingent on a good answer but the ravenclaw in me would really like to know." she waited patiently. He looked at her and sighed.

"The thing on my arm that all of this seems to come out of and work for is actually a quantum computer and knowledge repository for the ancient race all wizards and witches are descended from. When I put it on all of that knowledge was pushed into me with the warning that I was one of the few minds that could handle it. There is something physiologically different with my mind, I think because I died during the battle, that allows me to hold all of the information without dieing. And I need you to keep this to yourself for the time being as I am just not ready to tell everyone that I have a ten-thousand year old artifact on my arm." he waited. Padma studied him for a few minutes before she nodded and pointed to the new object now resting on the table.

"So forgotten history aside, which we will get into and write a book together about it, what does this new thing do?"

Harry picked it up and added one of the 'magic' crystals into the empty slot and a projection of the solar system sprang into being. A full hologram detailing even the asteroids in the system as it was at that moment. He gave it another command and the solar system shrank down and another system with only one planet but what looked like 3 stars appeared as well. Poking new system caused it to take over the view and then he poked the planet. Strange characters, to her at least, appeared and began to scroll.

"This, Padma, is a sensor system. It just scanned the solar system we live in and the nearest neibor and found a planet without an atmosphere or any life but rich in the resources we need to build even better versions of the computer we just finished and anything else I've shown you today."

"But how do you get there? Or breathe when you do? No atmosphere no air, even purebloods know that."

"I build a star ship and go set up a mining operation for materials. I'm going to need a cloaking device and shields, a transporter and nanites, only the last of which I can build just this second. There is no helping things then, if you're still interested then I could use the help." he smiled at her hopefully.

"What about your friends?" she asked.

"Ron wants to try for a career in quiddich and Hermione is going back to Hogwarts. I'll write them about some of it but I won't go into detail. Just that I've got a working magic proof computer and that I am likely to start mass producing them."

She nodded at his answer. His friends had their own things going on and he really could use the help and it was new knowledge no one else had access to which stimulated the ravenclaw in her. Helping him with this would have a steep learning curve and take most of her newly graduated time. Her family made a living selling potion ingredients and she knew it was likely she and her sister were going to get roped into the same unless she got another job. Maybe runes could help with his technology and he would need help making his computers do arithmancy.

"Whats the pay? I'm an assistant and consultant for your little project here and keeping quiet about the lost knowledge you've proven to have so I really should get paid if I am going to help you with this and not work on the family business. If I can bring my father in we could see about getting you the things you need, raw materials and such because I'm pretty sure you are going to need a supply line and this will help my family enough that we might be able to keep me out of the greenhouse." she smirked.

"Senior auror and we would for the most part be making calculators 'magic' crystal power sources. Something like this computer is just too much power for what arithmancy requires. Best thing is they should work even under water. But its late and I bet you were given a curfew." he looked to her again.

She shrugged. "It wasn't really a curfew but a propriety thing. It is a cultural fo-pas in India for a young woman to go off alone with a man. Father recognizes that a date in this country is done that way and that the old ways he was raised in won't really work for everyone else around us. He said that considers us on a date and that I shouldn't do anything with you that could bring dishonor to the family name. We are already looked down on because we're not British."

"Oh." Then he cocked his head. Turning back to the computer to get the full readout of the constructor he checked the raw materials he had left. Then entered his request and sat back. The table once again began building but this time two items at a time. They were about the size of watches and they would actually tell time with a digital display, but they were communicators. It would go on the opposite arm from the wand arm and allow instantaneous contact, no floo or floo powder required.

"Here" he said as they completed and he handed her one. "They give instantaneous communication without the need of a floo. In a moment I'm going to build one of the calculators and send you home with it to prove to your parents, read father, that I'm not out of my mind. If those things don't work I really don't know what I can say to convince him." turning to the computer again and designing a small arithmancy calculator and pushing the build button. That was the end of the raw materials they had collected today and he still had a ten-thousand pounds in his wallet.

"This should be plenty. So how do I work this thing?" he showed her how to put it on and call him pointing out that it had a secure channel that only these two communicators had. He taught her how to call him and showed her that the display was a holographic projector that would show his face when he picked up like a communication mirror. Then he handed her the calculator.

"You have to know that in convincing my father you will release the information about the technology through my sister right? Shes going to be there when I show my family."

"That is just fine. I didn't intend to keep that part a secret. But you better get going. You can use my floo."

He got up and escorted her to the floo and after giving her instructions to simply say 'Grimwald Place' to come through they had an aukward blushing moment as they locked eyes in front of the fireplace. She tore her eyes away and tossed in bit of powder.

"Patill House." she called and stepped through.
