Disclaimer:I do not own Artemis Fowl or Harry Potter. I do, however, own the plot of this story and any OCs I may introduce at a later date.

Before anyone points it out: yes, I know Gringotts was founded in the 18th century and Hugo de Folé was alive during the Norman conquest of England in the 11th, but please just roll with it. Continuity can get messed up in crossovers anyway, just assume that the timelines merged irregularly or something like that.

It came as a relief when Artemis dropped a knife on his foot.

Since the Bezerker's Gate incident, he had been unbelievably bored. Nothing exciting had happened for over a year. It had taken him less than a month to recover all his mental faculties – he was a genius, after all – and after that, he'd had nothing to do. The Lower Elements were surprisingly peaceful for once. Holly, as one of the LEP's best and brightest, was given so much to do that she barely had time to talk to him, let alone visit. The only contact Artemis had with the supernatural for twelve long months was his customary hacking duel with Foaly.

It had been early in the morning, and he had stumbled down to the kitchen, bleary-eyed, to find Butler cooking breakfast. As he lumbered to the table, he accidentally knocked into the chopping board and dislodged a knife. He saw it fall towards his foot. Butler was, thanks to his rather strenuous magical healing, too old to catch it in time, and Artemis' physical capability was certainly not up to scratch. He could only close his eyes and brace for the impact which never came.

Hearing Butler gasp, he opened his eyes slightly, then very quickly a lot wider as he saw the knife floating in midair, spinning gently. Examining it, he found that he could almost… feel it in the back of his mind. Concentrating, he made it move, floating up and down, left and right. It quickly drained his energy, but he brushed off the tiredness as he sprinted – actually sprinted - for his fairy communicator. Needless to say, he'd been on the first express flight to Haven.

Artemis Fowl was in trouble again. Currently, he was in the middle of a fairy lab with all manner of machines hooked up to him. Naturally, he knew what they were, having hacked the blueprints from Foaly's computer almost as soon as the centaur had come up with them. The demon warlock, No. 1, was examining him closely with a worried look. His eyes were glazed slightly with a magical sheen as his awareness delved into Artemis's mind, following the pathways of magic. After a few moments more, he surfaced, and sighed.

"It's just like you guessed, Artemis. The fairy magic you stole in the time tunnel kick-started your human magic."

Holly, sitting on the other side of her human friend, frowned. "But humans don't have magic."

Artemis gave his customary smug smile. "Not any more, but where do you think all those legends of wizards came from? Humans used to have magic, but somewhere along the way, we lost it. I assume it went with our connection to nature. However, the fairy magic reactivated the old pathways."

No. 1 grimaced. "And we have no idea what you can do now. There are no records of what human magic is capable of."

The genius smiled wider. "I guess I'll just have to find out."

#~#~#~#

Artemis sat in the middle of his room, meditating. He'd found that the exercise focused his mind wonderfully, and he had made vast leaps and bounds. At first, just lifting the knife had tired him, but now he could juggle ten or twenty small objects in complex patterns without breaking a sweat. His upper weight limit was significantly more than he could lift physically – he could bring the kitchen table or his bed clean off the ground, with some effort.

He had discovered other capabilities, too. He could communicate with animals, albeit in a very basic manner, passing images, simple concepts and emotions between them. Small wounds could be made to heal significantly faster – not a fairy level healing power, but enough to get rid of quite a nasty cut in a few hours instead of a few days. This, and other small things, gave Artemis a thrill he hadn't felt since he first discovered the existence of the People.

The process hadn't been easy. The first time he'd consciously tried magic in the house, he'd fried all the electronics near him. Fortunately, he hadn't been close to his computers. Experiments quickly revealed that electric currents were disrupted and short-circuited by magic. He worked out a way to incorporate magically conductive patterns into circuitboards, and upgraded all the manor's technology on the sly. It had been difficult, getting it done without his parents or brothers knowing, but he'd managed it.

Unfortunately, he wasn't free to experiment as he wished. The fairies, understandably, had put a guard on him, to be by his side at all times and report back on his magical status. His only consolation was that it was Holly, and the pair of them enjoyed being together again under more normal circumstances than their usual escapades. Comparing their magics helped Artemis greatly, as he often came up with ideas based off of fairy magic. More often than not, they didn't work – the two types seemed fundamentally different – but occasionally something worthwhile was produced.

It had been a few weeks since the arrival of Artemis's magic. The young man had recently perfected a new device – a magic scanner tuned to detect energies similar to his own. He hoped to pinpoint any others who had his gift. What happened next, he would never have expected.

Having launched the scanner on a satellite, with the People's blessing, he proceeded to link up to both it and Foaly, and initiated the scan. Hotspots showed up all over the world – there were large concentrations in nearly every major city, and smaller readings dotted everywhere, even on the most insignificant of islands. Commander Kelp was stunned. Foaly was stunned. Holly was stunned. Artemis was elated.

A whole new world to explore… this was going to be fun.

#~#~#~#

Dublin had registered quite highly on the scanner, but Artemis had chosen London as his first destination for the simple reason that it had shown a stronger concentration but was still within easy reach. Once he, Holly (in human disguise) and Butler had disembarked from the private jet at Gatwick, they followed Artemis's handheld scanner. It took them three hours, but they finally found the spot they were looking for. Artemis saw a strangely out-of-place building, with a sign proclaiming it to be the 'Leaky Cauldron Inn'. Holly and Butler saw only the shops to either side of it.

"Curious. Even though elves are inherently magical, you can't see through the illusion like I can. Perhaps it's keyed to human magic only…"

Holly frowned. "I'm more than happy to take your word for it, Artemis, but how do we get in if we can't see the door?"

Butler nodded, a grim expression on his face. "I agree with Holly. I can't let you go in there alone."

Artemis sighed, grabbed his friends – Holly by the shoulder, Butler by the elbow – and dragged them forwards through the door. As soon as they were through, they blinked at what to them appeared to be a room that had appeared from nowhere just as they walked into a solid wall. Their stunned expressions caught the attention of the proprietor, who laughed heartily. "So, you a Muggle-born then? Who are these? Dad and little sister? I'm Tom, by the way, proprietor of the Leaky Cauldron, best wizarding inn in England and the entrance to Diagon Alley!"

All three of them stared at the man in incomprehension. Artemis spoke up: "What's a Muggle-born? I hope for your sake it isn't some sort of insult."

Butler cracked his knuckles, and the man's laugh only intensified. "Oh, you must be from America, then. I think they're called… Baseline and Baseline-born over there? Baseline population, the non-magicals. It's seen as more politically correct. We call 'em Muggles here, and Muggle-born for the witches and wizard whose parents were Muggles."

Not in favour of letting anyone know just how ignorant he really was, Artemis nodded. "Ah, yes. I didn't realize you used a different term here."

This time, his accent was flawless American. "Could you please direct us to this… Diagon Alley? I haven't been here before, so I don't know how to get to it."

The barman beckoned the trio to follow, and took them out into a small courtyard at the back. Pulling a stick from his pocket, he tapped a sequence of bricks on the wall, and they rumbled, suddenly retracting backwards and opening up an archway. Through the archway was a bustling street full of berobed people and shops with outlandish names. The barman beamed. "Welcome to Diagon Alley, England's premier wizarding hotspot!"

Nodding his thanks, Artemis quickly led his companions through the streets. Glancing around, he wondered where to go first… until a large, white marble building caught his eye. The sign outside read 'Gringotts Bank'.

#~#~#~#

Things had gone remarkably swiftly. They had been admitted without much fuss – whatever those strange sticks were that the guards waved over them evidently didn't detect "Muggle" weapons. When a goblin had come over – at least, they introduced themselves as goblins, though they were nothing like fairy goblins (Holly nearly screamed at the thought of goblins being in charge of a bank, but swiftly calmed down when she saw how much shrewder this particular brand was) - Artemis had enquired as to the nature of wizarding currency and the exchange of Muggle money. The goblin assured him it was possible, and asked him for the name to open an account in. When the boy genius had said "Fowl", there had been a visible flinch. "Er… excuse me. I… need to check something."

The goblin had scurried off, and returned a few minutes later with an older and much more senior-looking colleague. This new goblin looked up at the young human with a hint of nervousness, and asked if the name Fowl was in anyway related to Hugo de Folé. Artemis, surprised, replied that it was, and the goblin had swallowed, going pale, before turning to the junior and telling him "take them to Vault One."

A terrifying cart ride later, Artemis was even paler than usual, Butler was green, and Holly was grinning from ear to ear. She had quite enjoyed it, though the two humans much less so. Before them was a truly huge door, four times the height of Butler and twice as wide, ornately carved. The bowing and scraping goblin asked if Artemis would care to touch the door. He did so, and his handprint lingered on the silvery metal for a few long moments before dissipating. There was a creaking and grinding from within, and the door parted at the centre to swing outwards and reveal a huge room stacked high with gold, silver and bronze coins. Artemis's jaw dropped.

"This, sir, is the entire wizarding fortune of Lord Hugo de Folé, plus the interest collected on it over the centuries. As the Fowl heir, it is now yours."

Artemis quickly did the maths using the exchange-rate figure given to him earlier, and worked out that the equivalent of roughly three billion pounds was sitting in front of him. He swept a pile of gold coins – Galleons, apparently (stupid name) – into a bag, and went shopping.

#~#~#~#

Obviously, the wand had to come first. Artemis opened the door to Ollivander's, the wand shop (since 382 B.C.? Really?). The bell jingled, and an old man shuffled out from between stacks and stacks of wands. "Hmm… wand for the little girl?"

The young human shook his head. "No, for myself. I, ah… had something of a mishap."

That was untrue, of course, but he didn't want anyone knowing just how ignorant he was of the magical world and just how late he had entered it. The old man raised an eyebrow. "Curious."

Shuffling back into the shelves, he emerged with a box, and opened it to reveal a wand. "Maple and unicorn tail hair, fourteen inches. Give it a wave."

Artemis did, and a shelf collapsed. Ollivander snatched back the wand. "No."

Back into the shelves he went, returning a moment later with a new wand. "Yew and dragon heartstring, eleven and a half inches."

The windows exploded.

Things carried on in this vein for a while. Half the counter was set on fire. Ollivander's eyebrows vanished into thin air. Butler's gun went off in the holster, hammering the floor with bullets and scaring everyone. Twenty-two wands later, the shop was a bomb site and Artemis was still wandless. Ollivander scowled. "Well, you're a tough customer, aren't you… I wonder…"

He disappeared again, back into the shelf maze. This time, he didn't return for several minutes, and when he did, it was gingerly, carrying a black box with great reverence. "Try this. Ebony and basilisk fang, thirteen inches."

The wand inside was deep black with an intricately carved handle. Artemis picked it up gently, and felt a warmth travel up his arm. He looked around the shop, wincing at the damage he had caused, and waved the wand. To his surprise, everything repaired itself in a flash of light. Ollivander looked grim. "I see. Very well, mister Fowl, that will be twenty Galleons."

Artemis handed over the money, and it was only after he was out of the shop that it occurred to him that he'd never told the man his name.
