Sorry for any inaccuracies with the Artemis Fowl canon, but I haven't read them in a while. And I'm not willing to reread all of them right this second just for your sake. But I'll probably reread it anyways soon.
Artemis Fowl II. Twelve year-old, straight A student, and criminal mastermind. I would say he has the swagger of an impeccable billionaire, but he no longer held that title. For nearly a year ago, the gaunt preteen's father decided to take advantage of the growing post-Soviet Russia economy. So his namesake took his bodyguard and 250,000 cans of cola into the Kola Bay, intending on selling it to the average post-Soviet citizen. What happened, however, wasn't exactly as planned.
The Russian Mafia didn't take kindly to a foreigner edging in on their business, and the bombing of the Fowl Star solved that particular issue. The supposed death of Artemis Fowl I sent his wife into spiraling insanity, and his son into denial. And the splurging of millions on expeditions to the Arctic in search of his father combined with the loss of millions of dollars of cola deprived the Fowl family of their honor and more importantly, billionaire status. Artemis II was not pleased with that, and after giving up on the expeditions and a temporary lull in his activities, he had a stroke of genius. Why not search for fortune with something completely untapped, never before touched by man? So he began investigating the histories of dozens of cultures, searching for lost treasures, myths of grandiose and luxury waiting on the bottom of the sea.
And he found an eventual trend. For every civilization had some link to things described as 'Fairies' or the 'People'. But after six consecutive failures to track his goal, he gave up. But a hidden message in a Nordic tome left a vague hint towards some kind of Equine creature, a diminutive variety, a pastel-colored conglomeration of sentient ponies with pure, untapped magical energy inside them. And he had found a way to retrieve it. After throwing nearly half his family's dwindling fortune to research, he had created a watch-type device, capable of rending reality itself.
The principle on which it worked was relatively simple. Artemis had combined varying amounts of hyper-dense elements with each other, and crafted an infinitesimal chamber with them. He then proceeded to hack a weather satellite, and divert its path into the orbit of a drone Artemis had put into the atmosphere. He simply attached a remote airlock, and contained a portion of vacuum within it. The weather satellite was then guided down onto the grounds of Fowl Manor, the chamber retrieved, and integrated with the watch's mechanism. The addition of a Pico-Hadron Collider within the vacuum completed the device. A simple combination of pressed buttons transformed the digital watch into a controlled black hole spawner.
And though it was an utter pain to calibrate it correctly, Artemis had coordinated the wormhole's energy and radiation to send an area around it into what he believed to be the location of his goal. And he was now ready for the first test with a living organism. A simple black market transaction and he was in the possession of a perfectly healthy, untampered lab rat. He affixed the generator to the rat, and set a timer on the wormhole, a short minute long duration test. He knew the watch would return on its own from a prior experiment, but he was unsure of the results of sending a living creature with it. He prepared the airlock chamber in his laboratory, and engaged the device, the rat disappearing in a vat of pure darkness, an extremely controlled black hole, singularity, wormhole, whatever you would prefer to call it. Just as instantaneously as it appeared, the wormhole disappeared. Artemis glared down at his Rolex, and began counting off a minute.
