RWBY/HARRY POTTER: Part II

Earth

Albus Dumbledore was not a man who was accustomed to being confused. He was one of the most well-learned Wizards in the world and counted among the most intelligent beings alive. His vast network of contacts and his own positions in education and politics meant he was privy to more secrets than any individual on the face of the Earth. It had been decades since he'd been so thoroughly lost.

He stood in the wreckage of the Potters' home, scanning for magical traces. His scanning spells—combined with general observations—told him three things: Firstly, that Tom had attacked the Potters, apparently having been told of their location by the treacherous Peter Pettigrew—just as Albus had planned. Furthermore, James Potter had apparently been killed in a duel with Tom. A pity, but an acceptable sacrifice nonetheless. The next thing Albus' investigations told him was that Tom had been defeated. Not killed, even without his magical scans, Albus knew his former student had grown too strong and given up too much of his humanity to be killed by any mere explosion. Still, from what little Albus could tell—the nature of the magic was very peculiar and was mixed in with another spell—Tom had lost a great deal of his power and would remained weakened for some time. Lastly . . .

Well, "Lastly" was Albus' problem. He was standing where Tom had fought and presumably killed Lily Potter. He'd hit her with a Killing Curse, no doubt of that. However, rather than being destroyed by some power of young Harry—the Prophecy said Tom would 'mark him as his equal'—it was apparently the result of some magic Lily had worked, but the aged Headmaster couldn't for the life of him discover what kind of spell she'd used. The Runic Array she'd used had been badly damaged by the explosion. What little he could make out was totally unfamiliar to him. Albus wasn't as well known for his knowledge of Runes or Arithmancy as he was his skills at dueling, his accomplishments at Alchemy, or his powers of Transfiguration, but he had studied these subjects and had a better than average grasp of them. Then too were the Astrological elements worked in—a subject Albus had, regrettably, lost touch with over the years.

It would be some time before Albus figured out what Lily's mysterious array was for, and by the time he did, it would be too late; the world Lily had sent Harry to would be too far out of alignment for Albus to follow after. Combined with the struggles of rebuilding the Wizarding World (in his own image, of course) the old Wizard's plans would be put on hold for almost ten full years before he could try to make contact with The-Boy-Who-Lived. This would require them to be greatly modified, as Harry would likely not be the weak-willed, innocent lamb he had planned for him to be.

Remnant—10 years later

Harry woke to the sound of a bird scratching at his window. Blinking, the boy opened his eyes and put on his glasses. About eleven years old—his parents couldn't tell his exact age—he had seen many strange and wonderful things in the world of Remnant. An owl scratching at his window, with a note tied around its leg was a new one, though.

The bird looked very annoyed: its feathers were all ungroomed and looked a little . . . singed? It was still very obviously a regular, tawny owl; not a small Grimm. Hesitantly, Harry opened his window. The bird jumped in and held its leg out for Harry. Untying the string that held it in place, Harry took the small scroll.

"Hey, Harry," his Mom asked, poking her head in. "What do you want for break . . . fast?" The silver-eyed woman paused. "Harry . . . What's going on?"

"I don't know," the boy said. "It was scratching at my window, and it had this tied to its leg." He held up the letter.

Harry's Mom—Ruby Rose—looked at the scrap of paper. It had been almost ten years since she'd seen anything like it, but she would never forget the night her son had come into her life. "Weiss!" she called. "Wake up! Now!"

"Dear Mr. Potter, we are pleased to inform you that you have been accepted at Hogwarts School of Witchcraft and Wizardry. Please find enclosed a list of all necessary books and equipment. Term begins on the September 1st. We await your owl by no later than July 31st. Yours sincerely, Minerva McGonagall, Deputy Headmistress," Weiss finished reading the first page of the letter aloud.

"Do you think it's from . . . my world?" Harry asked. The boy was well aware of his status as a reality-hoping orphan. Ruby and Weiss—his Mom and Mother—had been forced to explain it when he was seven and . . . things began to happen.

"Possibly," Weiss answered. "The question is, what do we do about it?"

"Beats me," Ruby said. She was examining the list that came with the letter. "I don't get half this stuff, and what did the letter mean, 'our owl?' Do they expect us to use a bird too?"

"Apparently," Weiss muttered. Given how little they knew of Harry's world; perhaps using birds as message-carriers made perfect sense to them, or fulfilled some symbolic purpose. "There's a bigger question we need to answer: should we consider sending Harry to this school at all?"

"Of course not !" Ruby yelled, throwing her arms around Harry. "How could you ask that Weiss?"

"I don't like it either, Ruby," the white-haired woman answered. "But, you know as well as I do that Harry needs training. And now that Professor Goodwitch is no longer with us . . ."

Ruby bowed her head. It had been difficult losing Glynda Goodwitch. The blond-haired Huntress was a tough teacher, but a good one and a wonderful ally. She was also one of the few remaining spell-casters on Remnant. She'd agreed to take Harry on as an apprentice when he was older. Unfortunately, she'd died a few years ago on a mission. Her students and friends took solace in the fact she had died protecting innocent lives. It was a good death for a Huntress.

It did, however, leave the Rose family with a problem; Harry now had no one to provide him with magical training. Considering the last time Harry's powers had activated they'd teleported him to the roof, that was a problem. One they couldn't solve on their own.

"Well, I have to learn to use these powers. Don't I?" Harry asked.

Earth

Dumbledore sat in his office, smiling as he read the reply the school owl had brought him. It looked out of place in Hogwarts, being written on crisp, white paper rather than parchment, but its contents were written in English at least. And they were pleasing to read indeed.

Dear Professor McGonagall (Who hadn't in fact read this letter or the previous. Dumbledore had acquired a copy with Harry's name on it, attached it to the owl, and sent the bird through his own portal. Then, he sat back and waited for its return),

We are pleased to hear of our son's acceptance into your school, despite not having applied to it. We have spent the last few days discussing this matter with our closest friends and relatives who are knowledgeable about these matters, as sending our son to a boarding school an entire universe away is not a decision to be made lightly. At length, however, we conceded that it would be wrong to impede the growth of Harry's gifts. Harry will arrive at King's Cross Station on September 1st to begin classes.

Sincerely,

Weiss Rose

Director of the Rose Dust Company and Huntress of Team RWBY

It was stamped with an unusual symbol, a rose blossom within a snowflake. The letter brought the old man both satisfaction and concern. On the one hand, it was pleasing to know that young Harry would soon be in his hands. On the other, the reply raised a number of worrisome questions. Firstly, the very wording of the letter suggested this Weiss Rose was not someone to be underestimated; the letter clearly spelled out that he or she was already suspicious of him and was capable of calling upon considerable resources should things go south. Ms. Rose had taken pains to highlight that Harry's new family and acquaintances were quite numerous and about as well informed as their world could be and implied that they were concerned about their adopted member's well-being. Possibly concerned enough to fight for him, if it came to that. Secondly, Rose was the head of some business or other. Dumbledore had no idea what the Rose Dust Company was, but he imagined it would at least provide Rose with considerable financial—if not militaristic—resources, and the aged wizard knew the value of money. Finally, Rose had claimed to be a Huntress of Team RWBY, another name Dumbledore could only guess at along with a title, but they were evidently of some import to include them with her signature.

But, most frightening of all was the fact that the woman had suggested that they would bring Harry to the Express by their own means, rather than rely on the Hogwarts staff to pick him up. How was such a thing possible? Did Harry's foster parents perhaps know how to transverse realities?

Dumbledore didn't know. He had sent the owl alone as a test; to see if his methods of travel into the other world and back were safe. When the bird had taken so long to return, the old man had presumed it dead and began double-checking his notes. When it did return, Dumbledore had to decide whether or not to risk a visit himself or send someone in his stead—McGonagall, perhaps, or Hagrid. On the one hand, he couldn't risk himself—his whole plan would fall apart if he were to die, and where would the world be without his guidance?—but he didn't want awareness of young Harry's whereabouts to become common knowledge. However, after sifting through the owl's memories of the affair (not easy to do with animals, but Albus was a rather gifted Legilimens) he had concluded that before releasing the bird to make its return journey, Harry's family had abandoned their home for a new venue. He wasn't certain where; they didn't take the owl with them when they left the house and were careful what they said in its presence, not that Albus had any knowledge of the local geography.

Albus could respect Weiss Rose as a tactician, but he wasn't fond of her for it.

Still, there was some comfort to be had in the fact that Harry would soon be in Hogwarts' halls. More to the point, in a few months' time, he would be trapped in his home world. Hopefully, alone.

It would be some time until Albus got the answers to his questions, and by then, it was too late to do anything about it.

Stonehenge is one of the most popular visiting sites in England. Every day, there are countless visitors eager to get a look at the much-vaunted ruin. Most are muggle and consider it either a curiosity, or admire it as a work of primitive engineering. Or as proof to any number of conspiracy theories, some more accurate than others. Alongside them, however, are visitors who know a touch more of the truth.

These visitors are aware of its Arthimantic layout, its secret runes, its location on one of the strongest ley lines in the world. All of it was designed to work as an enormous magical focus, a giant wand.

Except, it was a wand no one had ever managed to work. At least, not on public record. Rather than a wand, it was better to think of Stonehenge, and other such earthworks, as more akin to Portkeys or other enchanted objects; it had a single function, and you either used it for that function or you left it alone. What Stonehenge was made to do was still up for debate, and it was too popular amongst tourists, both Muggle and magical, to do any in-depth research.

Of course, sometimes the tours are interrupted. Such was the case one day, in mid-August, when a tour group saw an explosion of energy in the center of the ring as their bus was driving them to the location. The tour guide immediately turned the bus around and began yelling in his radio. Various Muggle tourists chattered among themselves about what could have caused it and what would be done. Magical visitors silently wondered when the Aurors or Unspeakables would arrive to investigate.

Actually, it would be some time before the Ministry of Magic could send a proper response. While the Ministry could monitor magical activity, it was not an omniscient Big Brother. Detecting underage wizardry in Muggle areas was easy, but put enough magical people together and all the Ministry could tell was that there was a lot of magic being used in that particular area; in this way, they lagged behind Muggle satellite surveillance. This meant that, because of all the magical tourists visiting Stonehenge coupled with the huge amounts of energy that ran through the ley line it was built on, the Ministry was never able to set up any real monitoring system for the site. Oh, they had agents in the tourist offices who checked and double-checked everyone who applied to visit, but that was it. Given that Apparating to or from Stonehenge was suicidally dangerous (old records reported those who tried either disappearing without a trace or blowing up in a spectacularly gory fashion) this was considered a workable solution.

Therefore, it was some time before the Ministry had even heard of the incident at Stonehenge, and when it did, the Ministry, being the Ministry, wasted a good deal of time arguing over proper procedure for a situation that had (a careful search of the records showed) never happened before. As such, by the time a team of Aurors had Apparated as close as they could to the site, then trudged the rest of the way there, they had precious little time before the local police came to investigate. In fact, they only got the time they did because the managers of the tour group wasted so much of their own first arguing over whether or not to call the police at all, and then arguing with the officers who arrived at their offices after being called in by panicking tourists.

Afterwards, both law-enforcement agencies would set up a quarantine around Stonehenge, calling in all manner of experts to investigate. The Muggle investigators found nothing, and were left with the hypothesis that a vicious, isolated lightning storm had gone off, or that some person or persons unknown had been fooling around with some manner of electrical device whose nature and purpose were unknown. The Unspeakables did slightly better, informing their superiors that Stonehenge had—somehow—been activated. That was all that was reported to the Minister, and that was all Fudge reported to the press. Some individuals (such as Xenophilius Lovegood of The Quibbler and Madame Bones of the Department of Magical Law Enforcement) thought there was more to the story, but Unspeakables remaining silent on their work, even to the Minister, was par for the course with the Ministry's most secretive agency.

Thus, no one knew that on August 1, 1991, Ruby and Weiss Rose and their son, Harry Potter, were teleported from Remnant to Earth, appearing in the middle of Stonehenge, becoming the first people in more than a century to properly utilize the ruin for its original purpose: a gateway to transverse universes.

Unlike the ritual Lily Potter had used ten years previously, Stonehenge—and its opposite in Remnant, a certain ruined temple located in the Emerald Forest—was not reliant on the movements of universes relevant to each other. Like an enormous, ancient telephone rotary, a would-be traveler "dialed in" the world they wished to visit, hit the "call" rune, and then were transported to the desired world's corresponding gate.

(Though the Rose family didn't know this, at the same instant they stepped through Stonehenge, two American filmmakers were hard at work shaping a feature that was built on this very idea, only with inter-stellar travel instead of trans-universal. They called their creation Stargate.)

"Hey, it worked," Ruby said, looking around. Instead of the ruined temple located in the Emerald Forest, she, her wife, and their adopted son were now standing in a ring of stones in the middle of a grassy plain.

"Professor Goodwitch's notes were accurate," Weiss remarked, looking around. "Hopefully, Mrs. Potter's will be the same. Now, it looks like there's a city that way," she pointed to a settlement that looked to be about ten miles away. Not a problem for two seasoned Huntresses and their child.

So, who likes the SG-1 reference? That was one of my favorite shows in college. I still haven't watched the original movie, but the DHD was a thing from the show, so meh. For those of you wondering why I was comparing Stonehenge to a movie I haven't seen, it's because the movie came first and didn't come out until 1994. I doubt anyone involved with the project was really thinking about doing a TV series based off it at the time.
