Disclaimer: I do not own Artemis Fowl or H.I.V.E. They are owned by Eoin Colfer and Mark Walden.

This is my first crossover EVER! The plot is meant to start after the beginning of The Opal Deception in the Artemis Fowl series and after Dreadnought in the H.I.V.E. series. Since I'm a bit rusty with both series, the characters may seen OOC. If they do, please let me know. I may have made Butler OOC in this story since I wanted to assume that thanks to the mindwipe, he thinks he's getting older and he eventually realizes that there is more to life than just being a criminal. But hey, maybe Butler has actually had those thoughts before. Who knows? Anyway…hope you enjoy the story!

EDIT (8/6/14): So I was reading The Eternity Code again and there is a part where Butler and Artemis are at a restaurant and he tells Artemis to try being nicer to people. So I guess it is sorta canon that he thinks Artemis is too smart for his own good. Heck, Butler even mentions school dances! And of course Artemis is surprised at his remark because Butler rarely offers opinions on personal matters (which is true). It's on page 8 if you want to read it. Obviously in this fanfic it'll be more than rarely, but hopefully it won't be so much that Butler appears very OOC. As I said above, it's intentional. But let me know if I've gone overboard with it; there is a limit to everything after all, and too much is too much.

Artemis Fowl the Second was in his room, working on his laptop. What should I rob this time? he thought. Another painting?

"OK," he said to himself. "Another painting then."

But which one? There are so many famous paintings, he thought. His house was already full of stolen paintings anyway. Oh well. It wouldn't hurt to add one more to the collection. Besides, I have already inherited a fortune (and I intend to make more), and jewelry doesn't fascinate me much. He liked old relics, but sometimes they could be pretty dirty, very fragile, or sometimes pretty big, like his house. His house was already an antique, as well as most of the things within it. It was built in the 15th century by one of his ancestors, Lord Hugo de Folé.

He decided to search up American paintings instead of European paintings. Besides, he liked the climate in America anyways. It was warmer than Dublin. He also liked that place called New York. It seemed really interesting to him, especially the skyscrapers. And not only that, but lots of famous places and things were located there, like the Empire State Building, the Statue of Liberty, and the 9/11 Memorial.

Artemis went on Google and searched up "New York art museums". He peered at the results of his search with a raised eyebrow.

"Seems like there's quite a few," he muttered. "Now, which one to choose…?"

He scrolled down the list of results. Among the results were places like the Metropolitan Museum of Art (which he already knew about), the Museum of Modern Art, the Whitney Museum of American Art, and the Rubin Museum of Art. How interesting, he thought. Let's check out the Metropolitan Museum first.

He clicked on it and was directed to the website. He browsed it and then he paused for a moment. Hmm, he thought. They sure have a lot of interesting paintings.

He clicked on "Collections" and scrolled through it. Among them he saw a painting of a green fairy attempting to steal a baby on a sunny day. It was called "The Fairy Thief".

Artemis zoomed in closer and peered at the thumbnail. This is weird, he thought. I thought this painting was in the International Bank. How is this possible? He then Googled the painting just to be sure and found out that it had been recently stolen by a person called the "Wraith", and for some reason had brought it to New York, where it was then placed in the Metropolitan Museum.

He had heard of the Wraith before. This person was famous for stealing valuables (especially jewelry) in museums. The funny thing was that nobody knew the true identity of the Wraith. They didn't even know whether the Wraith was a man or female.

Hmm...the funny thing is that I haven't heard about the Wraith in a while. I wonder what happened. He then pondered for a moment on whether the Wraith suddenly disappeared from the radar or was finally caught by Interpol.

But whatever, he thought. At least I've found it again. The only problem now is how to get there…and how to steal it.


It was the start of Christmas vacation. It was snowing outside, and chilly winds were blowing. Kids were playing outside, making snowmen, snow angels, and snow forts, and also having snowball fights. But not young Artemis, thought Butler as he watched his younger sister Juliet make a huge snowman. I mean, I guess it's great to have a very logical mind and a high IQ, but he's only 13. Sometimes I wish he never followed in his father's footsteps. Then again, he didn't really have a father growing up. But he should still try to be a little more considerate to others. Because Artemis rarely viewed anyone else he met as an equal, he was often isolated by others at St. Bartleby's. He would constantly be typing away at his computer, doing God knows what.

As he was thinking about Artemis, Juliet snapped him back to reality.

"Hello?" she said, waving her hand in front of his face. "Earth to Butler!"

"Um…huh? What?" he said. "What do you need Juliet?"

"Come check out my snowman. What do you think of it?"

He glanced at the snowman from his chair. "Nice," he said. "But you should add a top hat and a scarf. The poor snowman's going to be cold."

"Hmm…" said Juliet as she glanced at her snowman. "You're right! It'd look a lot better on him."

She ran past Butler and went back into the house. "Wait, hold on Juliet!" he yelled as she was about to ascend the stairs.

"What?"

"I'm going to talk to Artemis about something," he said as he stood up and walked into the house. "You get your hat and scarf and go back outside. And don't get into any trouble. Mrs. Fowl will be watching you."

"Um…OK," Juliet muttered, and went upstairs to her room. Butler then walked to the kitchen where Angeline, Artemis Fowl's mother, was cooking.

"Mrs. Fowl, could you watch Juliet for a bit? I need to see Artemis about something," said Butler.

"Sure," Mrs. Fowl said. "Besides, I need to wait for this to cool down." She set the timer to 15 minutes for the chicken soup that she just finished cooking. Then Juliet came running down the stairs with a top hat and scarf (which actually belonged to Butler but she had somehow stolen it) and ran out the door. Mrs. Fowl then watched as she adjusted the scarf on the snowman.

Butler sighed and went up the stairs. She had better not get into trouble, he thought. Because that girl easily gets into trouble often...

He went across the hall to Artemis Fowl's door. He knocked on it gently and asked, "Artemis? Are you in there?"

"Butler, is that you?" Artemis Fowl's voice asked.

"Yes," he said. "May I come in? I need to talk to you about something."

"Sure," Artemis replied, and he entered the room. "Actually, I was just about to call you for something as well." Probably another plan to steal something, he thought.

"We're going on another mission, Butler. We're going to steal a painting in New York."

"Okay..." said Butler. "Go on."

"I'm going to need your help. We need to make up an excuse to my parents so they'll let us go. And don't tell Juliet."

"Of course, of course," Butler muttered. "Just tell them that we're going to check out a museum for a school project. Or that you wanted to visit friends in New York. You can pick one."

"Hmm..." Artemis thought for a moment. "But obviously we're going to go by plane, although a cruise would be nice. However, that would take took long and we might get seasick..."

"You can get planesick too," Butler pointed out. "The only problems about flying to New York is that one, it's the holidays, and two, it's snowing. There would be a higher chance of having delays on our flights. And do you also know which hotel we're staying at?"

"That's true," Artemis agreed. "And I already know which hotel we're staying at. By the way, here are the plans."

He showed Butler the blueprints of his plan. "I'll be working on this. Meanwhile, you can use the computer to plan our flight."

Artemis opened his drawer and took out a remote. Then he aimed it at one of the walls and pressed a button. The wall flipped over to reveal an office desk, which also had a computer on it. Artemis walked over to the desk and continued working. Butler instinctively took his own chair and moved it over to where Artemis had previously been working. He looked at Artemis for a moment and wondered if he should tell him about his misgivings, but decided not. Instead, he started planning their flight route.

"Hey, Artemis," he said. "What day do you think we should leave?"

"Umm..." Artemis said, and took out his smartphone. "Well, today's December 14. We should leave on the 18th."

"All right, that sounds good," Butler answered, but he was still unsure about Artemis's plan. I wonder how this is going to work out...

What do you think so far? Please R&R! I will be working on my other stories as well and so I am not exactly sure when the next chapter will be up so feedback would be gratefully appreciated :)
