Hello! Still hoping for a few more reviews…thanks to everyone who has already reviewed though! Press the pretty review button for faster updates! I'm going away in about 3 or 4 weeks so I won't be writing for the rest of the year after that, and probably not until Feb next year! I'd like to finish the story before that, but there'll be a much better chance of that if I get more reviews! I don't own Artemis

Haven City, The Lower Elements

Holly led Artemis and Minerva down the streets of Haven, towards the Haven Museum. No-one paid any notice to them, as they blended into the crowd perfectly. Just as they were a block away from the museum, Holly noticed something strange.

"Artemis?" she asked suspiciously, "How is your arm healed?"

Artemis looked down at his arm, which was no longer covered by the sleeve of a suit.

"That's because…" he began, but decided it would be better with the truth. Even if he did lie, Minerva would probably catch him out, as they both had psychology degrees. He told Holly and Minerva everything, including how he had mesmerized his parents. When he concluded, Holly was quite amazed, if not slightly worried.

"You managed to mesmerize two fully grown adults without any training?" she asked in disbelief, "I'm not sure whether to be amazed or worried…last thing we need is a magical criminal mastermind."

"Ex-criminal mastermind," Artemis said, smiling.

"I suppose," Holly responded, smiling as well.

Before they could talk further about Artemis' magic, the trio arrived at the Haven Museum.

They swiftly swept through the first few rooms, before they reached a colossal size door, which was about 3 times as high as Butler. A vicious looking pixie guarded the door, but cheerfully opened it when Holly flashed her LEP badge. When they stepped into the room, Minerva and Artemis gasped. Lined on every single wall was a book, at least 1 million of them.

"We'll need to look at history before the fairies were sent underground," Holly exclaimed, pointing at a certain section, "that part is what we need to read."

The section in question was actually quite vast. There were at least 100,000 books there, all about the size of a detailed dictionary. Artemis, Holly and Minerva immediately started reading. Being geniuses, Artemis and Minerva read at incredible speeds. Holly, although reading a little slower, was going through about the same number of books though. Why? Well, let's just say that the teenagers were getting a little distracted at times…

After about an hour of reading, Minerva found what they needed. "The Avionaters were a race of underground dwelling fairies, famous for their incredibly powers, including the ability to morph, and their attraction to number sequences," she read out aloud. Artemis came over to read too. Soon, the two teens had ripped through the book, and both had worried expressions on their faces. "That bad?" Holly asked, although not really wanting to know the answer. Artemis nodded and Holly sighed.

Before they could research any further, a voice came in over Holly's helmet.

"Holly?" Foaly said quickly, "I think you better get back here. We've found something."

LEP, The Lower Elements

Holly, Artemis and Minerva arrived back in Foaly's office out of breath. "What is it, Foaly?" Holly asked quickly, as Foaly had sounded very urgent.

Foaly started, "When I…"

"We," Butler interrupted.

"…we finished working on my Magicoder, we picked up a very strange signal."

He clicked a button and a 1000 numbers appeared on the walls. 1, 3, 7, 9, 13, 15, 21, 25, 31, 33, 37, 43, 49, 51, 63, 67, 69, 73, 75, 79, 87, 93, 99…

"It was written with a type of magic which I've never seen before…I've been unable to decode it as yet."

"It's a lucky number sequence," Artemis and Minerva said simultaneously.

"A what?" Holly asked, amazed.

"It's a type of number sequence, first discussed by Stanislaw Ulam," Artemis exclaimed.

"Well, you can tell us about it later," Butler said, "first, I think you and your girlf-, I mean Minerva, should get decoding."

Artemis and Minerva both chose to ignore Butler's mistake although they both felt tingly inside whenever someone referred to them like that. "I think I'll let Artemis crack this," Minerva said, "He's probably a lot faster and more experienced at this than me." Artemis didn't respond, for Minerva was probably correct. He picked up two pens, one black and one pink. Then he stood in the centre of the room and stared at all the numbers (AN: Think 'A Beautiful Mind'). Eventually, he began circling different numbers with his pens. He drew lines all over the place, crossing from number to number. To anyone watching, it would look as if Artemis was drawing some very obscure picture. After half an hour, Artemis stopped, with deep frown lines on his face. "Oberon's Theatre," he said, grimacing, "17-November…"

Ooooohhh, 17-November…can anyone guess what that might mean? Please review, and I'll update!
