I'm Luna, and welcome to my first fanfic! Just so you guys know, this story is in third person, with alternating Artemis/Percy. Enjoy!

Also, this takes place right after The Last Olympian and The Last Guardian.

Disclaimer: I do not own Percy Jackson or Artemis Fowl. One day, I will though *evil Artemis laugh*.

Chapter 1: Artemis's POV

The day was going well until they landed on his roof.

Artemis was sitting by the fireplace, browsing through websites on his laptop. There wasn't any fire in the fireplace, but he felt oddly warm. And, to add to his discomfort, Beckett and Myles were having another one of their debates upstairs. It seemed like it had caused a rumble, especially with the yelling coming from the room.

He started to go upstairs to check on the twins, and to stop the racket. Surprisingly, he ran into them on the way up.

"What were you two fighting about?" He asked them, eager to know what had caused such a ruckus.

"Myles and I were having a discussion on the quantum theory," Beckett said, "Suddenly, we heard a large crack from the ceiling, and lots of yelling. We were coming downstairs to alert you that our house is haunted and we need to move immediately."

"Perhaps it was just your imaginations playing a trick on you," Artemis suggested, "Also, ghosts don't exist. Now, hurry downstairs and you can have some biscuits."

As the twins hurried downstairs, continuing their conversation, Artemis pondered about the situation regarding the mysterious noise. Since there was no attic in his house, the noise had to be coming from the roof.

"Butler," Artemis said into his walkie-talkie as he walked back down the stairs, "Are you in the office?"

"Yes Artemis, I am." He replied calmly.

"Change the security camera stream to the one broadcasting on the roof."

"May I ask why we have a security camera on the roof?"

Artemis sighed. "It's just what came with the security package, and is helpful in case of an attack on Fowl Manor from the air."

For a minute, all Artemis heard was static and clicks. Then, Butler finally responded to him.

"How the devil are those kids on the roof?"

Artemis ran as fast as his feet could take him to the office. When he walked in, his eyes immediately darted to the screen with the security camera stream on it. Though he could hardly believe what was on the screen, he was instantly relieved it wasn't another fairy foe he had to thwart. On his roof, there were five teenagers. A guy with black hair and sea-green eyes was holding hands with a blond-haired girl with an orange T-shirt. There were also a girl with red hair, a guy with a Rasta cap, and pale boy with olive skin. Everyone on the roof seemed to be yelling at the olive-skinned boy.

"Butler," Artemis said quietly, "Could you put the twins in their room and lock the door?"

Once the manservant left, Artemis pulled out his fairy communicator and said, "Holly?"

He waited patiently for about a minute, and then heard a response.

"What, Artemis?" Holly sounded slightly annoyed.

"Where are you?"

"I'm flying over the manor right now."

"Good," Artemis said, "Can you blast the mysterious people on the roof with you Neutrino?"

"Artemis, they could be innocent civilians." Holly reasoned.

"Do most civilians just climb roofs of manors without asking?" Artemis argued. "Anyway, they just appeared there, which means these are not normal civilians."

"Fine, Artemis, I'll do it," Holly said, "But Butler better help me carry them in."

"Don't worry, he will"

"I'm what?" Butler said as he entered the room.

"Holly is hovering above the manor, and she just knocked the mysterious people on the roof out." Artemis stated.

"Why?"

"I looked through the feed, and they just appeared up there."

"So that means they were either shielded, or they just 'appeared'"

"Butler," Artemis said, "This could be a possible threat of some sort, which we need to deal with. Luckily the twins are in their bedroom and Mother and Father are on a skiing trip in Germany, or we might have to tell them about this"

Just then, Holly's voice came out on the communicator.

"Artemis," she said quickly, "Both you and Butler need to get up here right this minute."

Artemis and Butler raced outside, and Holly unshielded before them.

"Butler, I'll bring the people down from the roof, one by one, and hand them to you, okay?" Holly said.

He nodded. Then, she turned to Artemis.

"They have weapons up there that you might want to check out," she whispered.

It was Artemis's turn to nod. Once Holly saw that he nodded, she disappeared out of the visible spectrum. Then, he waited for Holly to bring down each mysterious visitor.

When Holly was done, Artemis walked up to her.

"Do you have any of the weapons they had?" He asked.

"They had a baseball cap, a blue plastic hairbrush, some reed pipes, a sword, a knife, and a pen," she said as she handed the items to him.

Holly then went to go help Butler carry the mysterious people inside to the room where they had kept Holly when they first encountered the People. Artemis inspected each item carefully, and then began to inspect the pen.

On its side, it said Anaklusmos, which Artemis knew translated from Ancient Greek to Riptide. He slowly uncapped the pen, and soon was holding a three-foot long bronze sword.

Well, he thought, this is unexpected. Nothing is as it seems.

Thanks for reading that!

Reviews are like motivation for me to write quickly and put up the next chapter.

EDIT 11/15/12: Nothing major, but I would like to say that the update should come in ... ok maybe a month. I wrote myself into a corner. It's dark. But I'm trying to work out the bumps. And I have school. I'll try to work quickly but sometimes I don't have the time.

Also, who wants to Beta Chapter 2? PM me if you do.

Cheers,
