CHAPTER ONE - ENEMIES OF THE HEIR, BEWARE

"So the seven Millennium items are the horcruxes?"

"It makes perfect sense! Spirits and souls become sealed inside them. So we must gather and destroy them all. We already have the puzzle, of course, but finding the others will be hard," said Atem, tapping his twig against the ground thoughtfully. "Bakura has the ring and the eye. Mark has the rod... Shadi has the key and scales and then Ishizu has the necklace.

Yuusei nodded thoughtfully and leaned back in his seat. "How do you think we'll get them?" he asked. "I mean, I get the impression that it's going to be hard. Where should we start?" Yuusei leaned forward onto his knees, toying with the twig in his fingers. He couldn't help but appreciate the fact that Atem had gone through all this trouble to make him a Gryffindor quidditch uniform he would wear on his duel runner. He loved it. They pair also had matching robes now along with scarves. Yugi had a pair, but he never wore them which really upset Atem.

"Well... Uh..." Atem frowned. "I think we should start with Bakura. He might be easiest to deal with." Atem glanced around the room, looking at all the posters and drawings he'd done. "Aibou is meeting Kaiba today. He wants us to go," he said with a small sigh. "We can't duel later, sorry." He flicked his twig, the one leaf stuck on it trembling helplessly for a moment. "Bakura is in Slytherin. He might know about He Who Must Not Be Named." Atem stood when Yugi called. "You haven't met Kaiba yet, right? He's an okay guy, but if I had to sort him... he'd be in Slytherin. So we're sworn enemies, of course. And I see the resemblance between snakes and the Blue Eyes White Dragon." He nodded again thoughtfully, fingers running along his deck. His Gryffindor deck, though he'd let some Ravenclaw and Hufflepuff cards join. They were fine, after all. "I hope he isn't as mean to you as he is to Aibou."

"Atem. Yuusei. We're going now."

Yuusei nodded to Atem and then grinned. "Hey, let's take my runner. I repainted it." Atem nodded eagerly and followed him and Yugi outside. Atem gasped when he saw the brilliant red and gold runner, with the Gryffindor house crest painted on one side. It was perfect!

"Yuusei! It's like... It's like we have a Gryffindormobile. No. A wizardmobile!"
Yugi groaned. He wanted to look up and ask if he was being serious. But he knew he was...
Yugi looked up to the sound of screeching tires. Atem and Yuusei had driven off in their excitement.
Well, at least it didn't fly, right?
Oh right... He guessed he was walking now.

"The only thing that would make this better would be if it could fly," said Atem.
"I'm working on that," replied Yuusei, following Atem's directions to the KaibaCorp tower. "I keep going back to my time to get supplies. It'll fly eventually. Then we can work on making those Quidditch balls," he said with a quiet laugh. He pulled up the KaibaCorp tower and parked, waiting with Atem until Yugi arrived. He looked over at the pair, Atem still holding that ridiculous wand and Yuusei in his scarf. He scowled. This was embarrassing.

The trio made their way up the Kaiba's office after passing through security. Atem has talked the entire time about how muggle screenings were foolish and would not stop them. When they got to Kaiba's office, Yugi's cheeks were burning. What would Kaiba think of all this? He expected the glare, the sneer, the look of disinterest...

But then there was something else. Some kind of look he'd never seen before as he saw the scarf. "Who's the punk?" he asked, nodding to Yuusei. "Gathering more nerds?"

Yugi sighed. "This is Yuusei. He's visiting from... somewhere. Anyway, why did you call me here?" he asked, sliding his hands into his pockets and ignoring the whispering behind him.

"Look at this place."
"This is where the Slytherin common room is."
"Could he be...?"
"Seems like it."

Yugi sighed. "Is this about the finals again? I will be entering this year; I just need to get around to registering." He looked down at his feet. He missed the look Kaiba gave Yuusei when he saw the pair snickering.

"Yuusei, right?"

Yuusei looked up, expression unchanging and neutral. It gave away nothing. "What of it?" he replied, touching the end of his scarf.

"Nice scarf."

Atem's eyes widened as Kaiba smirked. He could see that look. A fan. A fucking fan. He grabbed Yugi's arm and nearly raced from the office, Yuusei following with a confused look. Once they were outside the building, Atem grabbed Yuusei's shoulder. "Kaiba knows, Yuusei. He knows what we're after. Kaiba... He's the heir of Slytherin!"

-xxxx-

Kaiba stood before his bathroom mirror, smirking into the glass. "So... A fan, huh?" he murmured, running his fingers over the chrome taps. He turned on the water and splashed water on his face, still chuckling to himself. "Gryffindor, hmm? Well, I guess it's time for things to get a little more serious." He dried his face and looked back at the mirror. All the things he could do with this... All the things he could use to toy with Yuusei and Atem. And in turn, of course, Yugi. Maybe even throw him off his game for the finals.

Kaiba pulled out a sheet of paper from his desk drawer when he returned to his room. "Time to build a Chamber of Secrets."

-xxxx-

"Yuusei, will it fly? We're going to need it to if Kaiba truly is the heir of Slytherin," said Atem. "Kaiba already has his jet. We'll need a way to keep up with him." He leaned over Yuusei's shoulder for a moment to look at what he was doing. "Do you think he's looking for the Horcruxes, too? To keep himself safe?"

"Possibly. I don't know for sure." Yuusei sat back and nodded to his duel runner. "That should work. I've done the best I can to make it fly." He then sat up fully and looked back at Atem. "I think we need to do some research on Kaiba first, though," he said firmly. "We'll test the runner later for flight."
He made sure Atem was on before he sped off, making his way toward the library. It was easy enough to sit down at the tables and pull old magazines and articles and internet sources that talked about Kaiba and his work with KaibaCorp.

"Adopted... rising to power... CEO of KaibaCorp... duelist..." Atem was scanning everything, his mouth set in a hard line. "I think he really is the heir of Slytherin. He looked up to see Yuusei scribbling something down. "What are-?"

"He has to be. Think about it. Left in an orphanage. Strange power over people. He can talk to his Blue Eyes, people fear him, he has followers, he's a powerful duelist, his past connects to the Millennium Items... He's the Dark Lord, Atem. I just know it." Yuusei set his pencil down and the pair looked at one another. "We need to defeat him."

"But we need to horcruxes. What do we do until then?"

Yuusei drummed his fingers against the table. "We fight him off as best we can," replied Yuusei quietly. "That all we really can do right now." He closed the magazine he was wearing and sighed. "Now what?"

"I'm going to look into figuring out how to get the ring and eye from Bakura," replied Atem. "I think that's the best thing to do. And we'll keep practicing our spells and whatnot. Oh! How have those been coming, by the way?"

"I just got the Latin dictionary yesterday. I'm excited to start filling out these notebooks you have." Yuusei chuckled and stood, checking out a few books they would need. "Now, I think it's time we check out that flying feature on the duel runner."

-xxxx-

"So you think this will fly?"

"Absolutely."

It had taken some work to get Yuusei's duel runner onto the roof. They had to keep twisting the wheels, moving around the hallway... It was a chore, bit worth it. They were finally going to fly! Yuusei turned on the runner. "I won't get on it yet. Just to be safe. If it can hover we'll ride it around for a bit."

Atem nodded excitedly and watched while Yuusei gave the runner a light push. It rolled forward...

CRASH!

Yugi looked up as Atem and Yuusei entered. They were both looking rather sheepish. He'd heard the crash, and he stood to peek out the window. He saw the smoke and the duel runner in a flaming heap. He frowned and looked back at the pair. "It didn't work... did it?"

"No..." they both muttered.

-xxxx-

Kaiba leaned back in his chair, smirking as he touched the engravings placed in the Chamber door. It was perfect. And so much more was coming along. He looked over at Mokuba and chuckled. "How is the tournament coming along?"

"It's going well, Seto. Soon, KaibaCorp will be hosting the first ever Tri-Duelist Tournament."

"Perfect."
