Hello and surprise!

This one has been sitting on my pc for a bit but I can't wait more! Wanna get it out!

I wanted to take a bite at this crossover and now the first chapter is done (it had been for a while, but I didn't know if I should publish it until after OSaB2 was done).

This first chapter is mainly set-up and introduction to the story.

I don't know when the next chapter will be out since I'm working on the next chapter for OSaB 2.

Well, I hope you like it and if you don't. Well I'll probably try my hand at it anyway.

So here we go!


Chapter 01 - The fall of the wizarding world

They say you don't dream in cryosleep.

It's probably true, but for one Harry Potter, now known as Harry Black, it wasn't.

From his own research, it seemed that even though he didn't sleep, it did slow everything down, making days seem like minutes, or at least he hoped so. Damn this cursed body of his. At least he didn't need to be trapped in his own mind for six years straight… He hoped… That would drive anyone mad…

If day's were minutes then six years would be 2191 days. 2191 minutes is… around 36-37 hours, so one and a half day-ish? He could survive that.

If anyone had told him back when he arrived at Hogwarts in 1991 that he would be traveling to a different planet in the year of 2124 he… might actually have believed you. Now if you asked him in 1990, he might not, since he didn't know about magic then.

Oh, Hogwarts… His first 'real' home… filled with friendships, magic, learning, psychopathic madmen, adventures, monsters that want to eat you, sports and… and… it all seems so long ago.

After what became known as The Battle of Hogwarts in 1998, Harry had enough of the wizarding world in general. Being an 18 years old war hero wasn't as fun as it sounds, except that it didn't sound fun at all. Magic and fighting was all he could remember and he felt paranoid most of the time. He had talked with Hermione and Luna about it and with their help he sought out a psychologist to get the help he needed. With their help he found one that knew about the wizarding world, who he could speak freely to.

The sessions made him realize that he needed a plan in life, to ground himself and be able to look forward into the future, instead of only living day by day, since he'd never knew what the day brought of horrors, and plan he did.

He decided to get an education, but being far behind wasn't fun, so he banded together with Hermione to study up to other muggles at their age, which was not a fun couple of months.

Harry had removed himself from the wizarding world during this time and didn't keep in contact with others. The Weasleys were grieving, Andromeda Tonks seemed to have disappeared also and everyone else seemed to be rebuilding. He still talked with Hermione and Luna, but it wasn't much since Hermione was set on going back to finish her year and help rebuild and Luna was busy editing and printing the Quibbler, which was now the foremost newsmagazine in the Wizarding World.

When it came to documents, certificates and ID they relied on Luna, who had learned the printing craft from her father and so with the help of Luna they printed, or more like forged papers, so Harry were able to take the GCSE. Yep, not a fun time, but it did make him curious about what the world had to offer outside the narrow view of not just the wizarding world but Great Britain in general.

.

.

.

In 1999 as others were preparing to go back to Hogwarts to finish their education, Harry was standing at Heathrow Airport ready to leave Great Britain behind for who knew how long.

He had made a deal with the goblins, gotten his inheritance, but had to promise not to darken their doors again, or spread the story of his accomplishment of robbing them. Apparently they respected what they had done, but it was still an unforgivable act, so they had given him what was his and nothing more. Honorable creatures in their own weird ways. Not had he could complain. Using an unforgivable and riding a dragon out of their bank after stealing from a vault. Honestly, he got lucky.

But here he was, ready to travel into the world on his own. To figure out where he was going to go he had wanted to use an atlas and a dart, but Hermione had hit him upside his head for even thinking of doing anything of the sort. What's a boy to do?

So when Hermione wasn't looking he picked his nose, rolled the booger between his fingers and flicked it at the atlas and when it landed he quickly flicked it away, closed the book and told Hermione that he knew where he was going.

So here he was, at Heathrow, looking up at the screens, looking for the TT423 flying to Kaunas, Lithuania.

"Laba diena dėstytojau."

"Laba diena." Harry said to the student on his way to the principal's office to deliver his resignation.

It was interesting how the world turned. He had only planned to visit the country of Lithuania and move onwards to the next country, but he had stayed.

It wasn't that many years since 1991, when Lithuania finally gained independence from the former USSR and the country was still establishing itself.

He had then traveled around the country, but had somehow ended up in the Kaunas, where he had worked a bit at a cafe, close to the local university. The place was a popular student cafe and he had helped quite a few students with their English homework and they had taught him Lithuanian as thanks. Interestingly, the university had heard about this and invited him to come to the university for a job offer as an intern in English since they were lacking one, which brings us to today, Harry working as a full-time English professor and it was here that he found a new love, a love for learning languages.

He was well liked by the students who felt his class was a room to breathe and have fun, since the other classes were very strict, stemming from the soviet era standards. Harry, knowing that he couldn't change the system alone and knowing that he wasn't gonna stay in Lithuania forever, so he tried to make sure that the students enjoyed, had fun and learned in his class, but he felt that it was time to go.

A loud sneeze sounded.

"Ajunngi?" One of his coworkers asked him.

"Issippoq!" Harry told him and got laughter in return.

"Soorunami!" Was the answer as he was patted on the back.

And it probably was an 'of course'. It was autumn in Qasigiannguit, a tiny town on the west coast of Greenland. He had wanted to go somewhere completely different and he did. Somehow one of the professors was related to someone working on one of the Royal Arctic Line ships that were transporting goods to Greenland and he had gotten work on the boat in the kitchen. It had been a rough trip, but he got his sealegs and after two weeks of sailing they had arrived in Greenland. He learned that the town originally was built on the other side of the bay it was located at, but the high winds from the tall mountain next to it had pushed the houses into the fjord, so the residents relocated to the other side.

He had gotten a job at the local store and did his best to learn the Greenlandic language and so far it seemed to be going well, even though he sometimes messed up and everyone got a laugh out of it. But other than embarrassing himself with his trial and error of the local language he knew, knew that he wanted to learn more languages. It wasn't only because of the way people smiled when he tried but also how a new part of the country opened up for him. It was like language was a key to understanding the culture better and he was all for it. He had gotten addicted and he needed more.

.

Harry tried to keep in touch with his friends back home but Hermione, in wanting to protect Harry from his SPS (Saving People Syndrome) convinced others to share as little as possible, which then naturally made their connection fade even more. Bonding over shared traumatic events only carries so far, especially when one wants to leave and the other wants to stay.

But what was it that Hermione wanted to protect Harry from?

Unbeknownst to Harry, unrest was stirring in the wizarding world once more.

It had happened slowly without anyone realizing what was going on and in the year of 2005 the unspeakables in the Department of Mystery realized that it was too late.

What they realized, to put it simply; magic had been disappearing. Spells weren't as powerful, less first generations and more squibs were being born, magical barriers were losing their potency and magical devices were either slowing down or shutting down.

The brightest witches and wizards all around the world were trying to figure out why but in the end there was nothing they could do and 2005 became known throughout the Wizarding communities around the world as the official beginning of the decline of the Magical World.

.

.

.

Harry learned of this predicament when he went to Spain.

He got a job in a hostel or 'albergue' in the northern province of Asturias for pilgrims traveling The Northern Route of The Way of St. James.

He liked it there and he had the chance to meet people from all around the world while still staying incognito. It wasn't like magicals were thinking about taking a pilgrimage.

It took a while before Harry learned that the small hostel's owner was a squib. When they figured out that they both knew of magic, a surprise shared over a bit too much homemade red wine and pinchos, born from the feeling of not fitting in with the family since they didn't inherit the 'right' blood, the owner Daniel, who thought Harry was a squib as well, happily shared the news that the Wizarding World was going down.

Harry had wondered if he should contact people back home but since he had to learn the news on his own and also hadn't talked with anyone from England in years he decided to let it go just as his boss slapped the table and raised his glass.

"¡Es la leche, Harry!" Daniel said ecstatically.

"Es así." Harry said as he raised his glass, downing it but not being fast enough to decline the offer for the quick refill from Daniel's two liter dark green glass bottle. He honestly didn't know what to feel about it, especially since he didn't feel like his magic was diminishing, actually it was the opposite, it felt like it was condensing and getting stronger to the point it was having effects on him.

Not only did he not need a wand anymore but… He had started to use charms on himself since he wasn't getting older.

The sound of newspaper pages turning, the year in the top corner of the front page stated 2040. It was quiet at the sea as he learned that out of the tourist season, midday in the middle of the week was the biggest change that there would be no people here next to the lighthouse Lodbjerg Fyr slightly north of the village of Agger in the northwestern part of Denmark.

Harry didn't work, he had enough money not to and here he just wanted to experience the language and the peace and quiet, so he volunteered at the cafe at the lighthouse and helped clean the place.

The last couple of years he had come to terms with his not aging. He couldn't really figure out why since there was not really anyone to ask without outing himself as both Harry Potter and possibly immortal.

Before arriving in Denmark he'd lived and spent years in Finland and Greece so now, by his account he knew seven languages and he still wanted more. Using smartphones had been nice and with the progression of apps he had a helpful tool in his hands for learning, but he felt that it still didn't beat living, breathing and talking in the country itself.

While traveling around Denmark he realized he needed to do something about constantly using a charm to fake his age, so he had decided to make a new identity.

Finding out where the Wizarding capital of Denmark was located had been surprising, especially since the town had a Museum of Witch Hunt, which was run by magicals as well as being in the oldest town in the country; Ribe.

Hidden underneath Ribe Cathedral was the Danish magical government, who at the time had a lot on their hands.

The magical were suffering from their lack of magic and the Danish magical government, Trolddomsparlamentet, had started their joint effort with the non-magical government, a rehabilitation plan of either adapting or helping magicals to live in protected communities.

Because of this, his paperwork actually went fast and it seemed they didn't really look at it properly or care since it was such simple paperwork compared to rehab which was lots and lots and lots of paperwork.

So now, Sirius Peverell, was sitting outside a lighthouse in a very quiet part of the country, reading his paper and eating smørrebrød, not having to hide his age.

Since it was part of a National Park there was a lot of space and it was here, in the remote Danish moors that he finally became an animagus. There was a stable deer population and he always wondered if he took after his father, but he will never forget the first time he changed. To his surprise and great happiness the sky was calling him. Spreading his wings and taking flight he relished the feeling of the wind he hadn't felt since the last time he rode a broom, which he wasn't able to anymore since the magic in the inanimate object didn't last long. Looking out he was stumped as he saw the waves from the North Sea hit the long sandy coastline where the moors and scattered forest stretched into the horisont.

Weeks later he heard the rumor about a golden eagle being spotted, which was big news for the local ornithologists. At least he knew what eagle he was now.

He reached down into his pocket and pulled out a Danish 20 kroner coin. holding the gold colored aluminum-bronze coin up between his index and his thumb towards the blue sky and looking at the profile of the late Queen Margrethe II of Denmark he said to himself "Italy or Austria".

Closing his fist, letting the coin fall on top of his up-facing thumb he placed the tip of his thumb under his index finger and flicked.

Watching the coin spin in the air reminded him of days of playing quidditch, ages ago he caught the coin and slapped it on top of his left hand.

Lifting his hand he looked down at the image of the three lions and a decision had been made.

"I guess I'm going to the home of the Wiener Schnitzel." He said with a smile and ate the last bit of his dark rye bread topped with breaded fish, cucumber and tomato

.

"Studying both anthropology and linguistics?" The lady behind the counter asked.

"Yes Ma'am." Harry answered as he stood at the counter.

The year was 2118 and a lot has happened since he flipped a coin on the Danish west coast. He still had the coin, though it was pretty worn out by now.

In the year 2066 the planet Polyphemus and especially its moon Pandora had been discovered and only nine years later the first launch was sent its way which landed in 2084. Wasn't it a surprise when they realized that there was life, LIFE! on Pandora. A life with its own culture and own language! The age old question had been answered! We are not alone. He had followed all news he could find about it even as he traveled the world, living in many different countries on all continents, well except Antarctica, learning cultures and languages.

Curious and wanting to know more and get a deeper understanding of everything he had learned and experienced, he decided that it was about time he got his paperwork in order again and got an education and maybe even be on the frontline of any knowledge about the new world out in the final frontier.

He had used magic and made a fake birth certificate, stating Harry Black was born in 2100 at home on Tangier Island, Virginia, which explained his accent. He had chosen the date since it was also this year that marked the official end of magic and the end of the wizarding world. Harry hoped that his extensive traveling and knowledge would let him start on the two masters; anthropology and linguistics.

He was able to get a spot through an entrance exam and it was at this university he would meet someone who would be instrumental in the direction that his future would take.

They met in the library, both looking for the newest articles and papers on the moon pandora. Harry was trying to absorb anything he could get his hands on about the Pandorians, or as this paper told, the Na'vi. Finally some proper information.

After going over some survey photos of the nature of Pandora he looked up towards one of the high windows and into the sky beyond. The progress of modern tech and living in the city made it impossible for him to use his animagus form, oh how he long for the clear sky.

As he was immersed in his thoughts, someone sat in front of him at the table. He looked up to find a kind looking young woman looking at him expectantly.

"Can I help you?" He said with a friendly smile.

The woman cleared her throat and sat a bit straighter.

"I saw you looking at the paper on Pandora. I was wondering if you could show me where it's located, I'm still new to the database system here." She said as she gestured to the see-through screen at the station he was sitting at, filled with the newest information on the moon.

"Of course, let me show you." He said as he scooted to the side to make space for her. After he showed her basic ins and outs of the library-systems digital catalog she sat at the station next to his and started her own reading.

He doesn't remember who started but as they sat there reading, one of them struck up a conversation and they easily became friends. At first they would just share the library table and talk about the newest finds on Pandora, but soon they would meet often and talk about their interests and studies, as they were both working on masters, Harry about to finish his as Grace who just started hers.

Harry was quick to realize that Grace Augustine was a brilliant woman and that her knowledge on botany was unmatched.

.

2120… Graduation! The only one that showed up to celebrate him was his apartment-mate Grace (good apartments aren't cheap, thank you), but it was okay. He smiled as he shook hands with the dean. He did it.

On the other hand, news arrived about rising problems between the Na'vi and humans.

.

.

.

Two years had passed since Harry graduated and life was good. He got papers published, had a small teaching/lecture gig at the university and access to a lot of information.

Harry was sitting in his room, door open, working on his next lecture when Grace burst into the apartment.

Turning and rolling his backless chair in front of his bed to get a better look at her, since the last time she made an entrance like this was when some guy from her master course had professed his eternal love for her in the middle of the university's lobby. He noted the difference this time as she didn't seem embarrassed and angry, but instead frantic and extratic… frantatic?

"You okay?" He asked, which he immediately regretted as she whirled around, eying him like a tiger seeing a bunny and before he knew it she rushed him, jumping before she reached him and sending them crashing onto the bed, Harry on his back under her and Grace straddling him, grabbing his shirt and shaking him, seemingly trying to form words but even though her mouth was open, nothing was coming out.

Grabbing her wrists, pulling her down and twisting, he got on top of her and held her in place.

"I might be a polyglot, but I need a little help here!" He said to her as she tried to get herself under control. Taking some deep breath she tried talking to him in a calm manner which resulted in her shouting at him.

"They want me to go to Pandora!" She shouted, sporting the biggest smile that seemed to be on the edge of breaking her face in two.

"What?" Harry said as he released her and they both sat up.

"They want me to go because of my paper on xenobotany!" Grace shouted.

"That's amazing!" Harry shouted back at her, genuinely happy for her.

"But that's not the best news!" She continued in the same voicelevel.

"What is the best news?" Harry asked, since he couldn't think of anything she would think was better than her being offered a spot at Pandora.

"You're going with me!"

…silence…

"What?!" Harry shouted at her, making her laugh out loud.

"Yes!"

"Really?!"

"Yes!"

"You're not pulling my leg?!"

"We're going to Pandora!" She shouted.

"We're going to Pandora!" He shouted back.

"We're going to Pandora!" They shouted together as they hugged and jumped in circles on his bed.

.

.

.

When she had been called to a meeting and offered a place on the next ship out as a xenobotanist she had been ecstatic about it.

She had wanted to go since she learned about the moon and to be given a chance was like a dream come true and she had said yes immediately.

As she was about to leave the meeting she had heard them talk about needing a xenolinguist as well.

Now Grace had known that Harry wanted to go to Pandora as well, maybe even more than her and jumping at the chance she excused herself for listening in and offered her advice on who she thinks would be an asset.

The meeting then ended up taking much longer time as the board brought up his CV and papers while Grace adding her own reasons why he would be the best candidate, which culminated in them telling Grace that if he wanted the spot, the spot was his.

Grace, feeling that she knew Harry pretty well, said that it would be his greatest wish. Hands were shaken and Grace was practically running back home, smiling like a maniac all the way.

.

.

There were countless things that needed to be done and prepared for the journey, as they both knew that it would be a one-way-trip.

They had to take tests, get acquainted with the ins and outs of the Avatar Program, do simulations and give samples for the avatars that they were gonna 'drive' on Pandora.

At first Harry was worried about this, so he did some tests on his own. Luckily it seemed that if he took blood out of his body it lost its magical properties and was just regular blood so using it for the program wouldn't be a problem, at least that what his theory and from the samples he gave, no problems arose.

This way two years went by in a flash as they boarded the transport module, entered their capsules and listened to the speaker going through what was about to happen to them.

"Six years in a capsule…" Harry mumbled, "Pandora here we come…"

.

.

.

They say you don't dream in cryosleep.

It's probably true, but for one Harry Potter, now known as Harry Black, it wasn't.

Light suddenly flickered and he opened his eyes as he was greeted by a female med-tech with the name tag 'Jen' printed on her shirt, floating around.

"Are we there?" Harry asked hoarsely, his throat dry.

"We're there, Sunshine. Up and at 'em." She smiled at him.
