Mysterious Waltz:
A Gundam Wing / Fushigi Yuugi Crossover

Disclaimer: I don't own any of the characters. And the plot is loosely based off Fushigi Yuugi. I wish I owned it. Oh, I really wish I did. But I don't. So please don't sue me… or I'll write more just to spite you! *grins*

Note: at the end of each part there will be a "Characters so far" section to remind you of which character is which. Given the large amount of characters that will be introduced in this story I figured it would help a lot. Also, unless the character has shown up in the story don't expect there to be a thing for him or her yet, I'm not going to give away spoilers. :p

By: Snow Tigra (with large amounts of help from Khadaji and Jo-san and Stardancer!)

Part 1: "This is the Story…"

Quatre sighed softly as he set down the violin on the floor. Leaning forward and setting his chin in his hands he contemplated the polished wooden instrument. He had a concert in less then a month and he still hadn't managed to get that one part down, no matter how hard he practiced. He was about ready to pick up the instrument and chuck it out the window, but couldn't bring himself to do it. He truly loved the violin it was just that… just…

"Why can't I get that note right?!"

He sighed softly again and stood up. Walking over to the case he placed the instrument gently inside, deciding to give it a rest for the day. It was time to go home. As soon as he got back he planned to curl up next to the window in his room with a thick book and read until either his eyes hurt or he fell asleep, which ever came first. He didn't have any homework and he was already ahead in studying for his entrance exams so he deserved a good rest from the real world. It would be so nice to dive into a good fantasy novel, he couldn't wait.

"Onii-chan, come on! Enough practicing already, it's time to go."

Quatre turned to see one of his schoolmates knocking on a practice room door. A second later the door opened and she held it there. Quatre stood silently and watched, curious who was in the other practice room.

Soon a boy his age emerged from the room. He wore the normal school uniform of black pants and a button down white shirt with the logo over the breast pocket. That should have passed him off as normal and Quatre wouldn't have thought another moment about it or him any more… if it weren't for his eyes.

Then again perhaps eyes weren't the way to put it, because Quatre could actually only see one. The other eye was obscured by a long set of caramel colored bangs. The eye that did show, however, was the most beautiful shade of emerald green Quatre had ever seen. Quatre's first thought was that the girl next to him was his girlfriend but he immediately remembered what she'd called the boy, onii-chan. They were brother and sister? They looked almost nothing alike.

She looked nothing like him with her curled auburn colored hair and glassy blue eyes. They looked more like a couple then siblings but Quatre wasn't one to judge since he himself was an only child. Still they seemed like complete opposites since she was being so talkative and so far he hadn't said a single word.

The boy stepped out of the room with a flute case and backpack in hand then silently followed his sister from the practice hall. Quatre, before he even realized what he was doing, began to follow them. He followed the two away from the school and down the street, his earlier plans to curl up with a novel completely forgotten. Instead he wanted to know more about he silent boy, or at least learn his name. He soon realized they were headed straight for the National Library.

Perfect! Quatre thought, now he had an excuse to keep following them. Not to mention he had an explanation if he was caught in the act. But those happy thoughts were quickly shattered when they entered the library and the siblings disappeared into the crowd of people. He couldn't see them anywhere. Quatre's shoulders slumped in defeat and he sighed softly.

"Oh well, it was a stupid idea anyway."

Accepting his fate with another sigh of disappointment Quatre headed up the stairs to the fantasy section. He was at the library so he might as well get a book and return to his original plan. A good book and the warmth of sunlight from the window would easily get his mind off those shimmering emerald eyes, he was sure of it.

It didn't take long before Quatre had found a good number of books that would keep him busy reading well into the night. He was lucky it was a weekend, he'd have plenty of time to read all of them, at least once. Carrying a rather large armful Quatre made his way back toward the stairs and the checkout counter below. However as he reached the stairs, misjudging the distance, he stumbled and was sent flying.

In that single second the world around him seemed to flash into bright red. All around he was surround by dancing, leaping red flames. A large bird made of fire with glimmering green eyes screeched at him and took off into the air, sending small ashes flying from its tail. A phoenix? Quatre blinked and whirled around.

All around him stood dozens of figures dressed in different colored robes. There were twenty or so in all, standing in four equal sized groups. Each group had its own color and as the bird disappeared from sight all of the cloaked figures turned to look at him. Then, as suddenly as it had started, the illusion stopped and Quatre found himself flying through the air toward the bottom of the stairs.

He let out a cry of surprise as a hand latched tightly on to his arm and yanked him back to his feet, preventing his fall. Quatre dropped to his knees to catch his breath and regain his balance. His mind immediately dismissed the strange vision in favor of seeing who had helped him, so he looked up… and froze.

"Are you all right?"

Quatre swallowed and nodded slowly. It was the same boy from the practice room, the one who'd had the flute and the bright green eyes. Quatre quickly adverted his eyes to the floor to hide the small blush of embarrassment crossing his cheeks.

"A-arigatou."

"No thanks necessary." The boy said quietly. When Quatre looked up he found the boy offering him and hand to help him to his feet. Quatre took it and stood up. He glanced down the stairs quickly to avoid meeting the other boy's eyes and gave a start. He noticed his books lying scattered down the stairs with a small amount of one he hadn't picked out. That's when he realized the other boy must have dropped his books to catch him.

"Gomen!" Quatre hurried down the stairs and began to pick up the books. I must look like such a fool! He scolded himself miserably.

The boy leaned down to help and soon all the books were picked up. One book was left lying on the ground and neither reached for it.

"Is it yours?" Quatre asked quietly, he didn't recognize it.

The boy with the emerald eyes shook his head. Slowly he reached forward and picked up the book. Raising an eyebrow he read over the title.

"The Universe of the Four Gods," he muttered softly.

"Never heard of it." Quatre murmured. He took it from the boy and opened to the front page and began to read the first paragraph.

"This is the story of a young girl who, after she came to possess the stars of Suzaku, made all her dreams come true. The story itself is a spell and whoever reads it becomes the girl. For the story comes true and the spell is cast as soon as the first page is turned." Quatre paused and glanced back at the emerald eyed boy in confusion. "That's strange."

The boy frowned. "We should take it to the front desk, it's possible someone might have dropped it."

Quatre nodded and stood up, closing the book in his hands. As they stood up and headed for the front desk the girl Quatre had seen with the boy earlier appeared at the top of the stairs.

"And just where do you think you're running off to?" She mock demanded.

The boy turned to her and offered a light smile. "Just bringing this book back to the front desk. I'll be back."

The girl nodded. "All right. I'll be up in the manga section if you need me."

The boy nodded and turned away, meaning to head with Quatre to the front desk. Though, strangely as soon as his sister disappear a strange red light began to emit from the book. Quatre immediately stopped walking and his eyes grew wide.

Quatre gave a small cry as the book seemed to come alive in his hands. It shone brightly with a blinding light and grew burning hot, causing Quatre to drop it to the ground. The book landed with a loud crack on its spine and snapped open to reveal two pages. One was covered with words, ancient letters; while the other page held the picture of four figures dressed in long flowing robes.

"What's going on?" Quatre whispered in a shaky voice.

The boy opened his mouth to respond but all of a sudden a bright red light burst from the book, shooting straight through the ceiling. Quatre and the boy both threw up their arms to protect themselves as Quatre let out a small cry. The air around him turned warm and for a moment he found himself and the boy standing in a world made of bright red flames. Then there was the face of a huge bird made of fire, a phoenix. It gave a loud piercing cry and Quatre was suddenly falling.

Darkness swallowed him before he had a chance to cry out again.

**

Trowa was the first to wake up. He opened his green eyes and blinked with surprise, where were they? He found he was lying on a hard ground of dry sand and his arms were wrapped protectively around the blond boy. For a moment he didn't dare move, afraid this was all some strange dream from which he did not wish to wake. After a few minutes he silently scolded himself for being irrational and gently nudged the boy until he began to show signs of waking up.

Quatre blinked his eyes open and glanced around in question. His eyes widened at the sight of Trowa lying next to him and he tensed up as he discovered Trowa held him in a loose but protective embrace. Trowa noticed him tense up and quickly pulled out of the embrace as Quatre's face grew slightly red. Sitting up he glanced around at the arid and relatively dry landscape in confusion.

"Where are we? What happened?" Quatre asked sitting up.

"I don't know," Trowa replied softly as he stood up. Taking one last look around he turned to Quatre and offered a hand to help him to his feet. "Where ever we are we appear to be stuck here."

Quatre frowned and peered around them. The library was no where in sight, for that matter he could really see any buildings. Instead they were surrounded by dry land, and above them was a bright and warm sun. Small patches of brown grass littered the ground around them while only a few scattered trees lay in sight. Quatre swallowed and rubbed his eyes, trying to figure out exactly where they were.

The landscape was dry, there were no buildings or houses, no real sign of life. Well, except for the small outline of a city far in the distance to the south. Quatre turned in that direction and pointed.

"It looks like a city."

The boy walked to his side and nodded. "It seems like as good a place as any to start."

Glancing around at the area where they had fallen Quatre noticed that whatever had transported them had only transported their bodies and clothing. His backpack and the books he'd been carrying at the time were no where in sight. Sighing softly he glanced back to the boy. "Shall we go?"

"Yes. But, first, for the record, what is your name?"

"Quatre Winner," Quatre replied, brushing the dust off his school uniform. "And yours?"

"Trowa."

"Nice to meet you, Trowa." Quatre responded with a smile. Trowa offered a light one in response.

"Well what do we have here?"

Both boys whirled around in surprise to find a group of roughly dressed men with large weapons. Trowa immediately stepped in front of Quatre, stretching back his arm to make sure Quatre stayed behind him. His eyes narrowed as he watched the men who moved to surround them.

They were dressed in old period clothing made of tunics, sashes and baggy pants. All wore their hair tied back in long thin ponytails while the one who appeared to be their boss was the only clean shaven one of the group, and he held the largest sword.

"Looks like a couple of foreigners, boss." Responded one of the men. He snickered and leered at Quatre, who quickly took a few steps back.

"Yeah, they must be rich to afford such funny clothing."

The boss grinned. "Especially the blond one, he'll fetch a good price."

"Slave traders," Trowa hissed dangerously. He locked his eyes with the slave traders and crouched slightly into a fighting stance. "Quatre, get out of here!"

"But…"

Two of the slave traders began to advance toward Quatre, drawing their swords. Trowa jumped forward quickly dropping to the ground and kicking the first thug's legs out from under him so he tumbled backward into his partner.

"Go! Now!"

Quatre shook his head but forced himself to turn around and run away from the slave traders and Trowa, not letting himself look back. As he raced forward he could hear the sounds of the fight, but all he could do was pray that Trowa would be all right and find a place to hide until it was over.

**

"You going to take us all on boy?" The boss sneered at Trowa.

Trowa didn't answer, instead he just glared back, his hands raised in readiness. From the looks on the faces of the other two slave traders he could tell Quatre had gotten away and now they were all concentrating on him. Three on one was horrible odds but still Trowa was glad the other boy had gotten away, he didn't look like the type who knew how to fight. Better that he got out of sight.

One of the slave traders rushed forward, his sword swinging high. Trowa jumped to the side and reached back, grabbing his arms and twisting it tightly, knocking the sword from his hand and then spun around and punched him hard in the gut. The slave trader grunted and clutched his stomach as he moaned in pain. Trowa immediately turned his attention to the other two, who certainly didn't look happy at the fact that he could fight.

"He's mine," growled the second slave trader and he moved forward, slicing his sword out toward Trowa's midsection. Trowa flipped back and kicked the man in the wrist, sending his sword flying as well. Yet this time Trowa landed and caught it steadily in his right hand. Jumping up he leveled the blade at the second slave trader.

The second slave trader froze with a look of slight fear across his face, but then his lips slowly slithered into a grin. Trowa's body stiffened as a cold sharp piece of metal rested against the back of his neck, he swallowed and scolded himself for not paying attention to where the boss had been the entire time.

"You're a lot of trouble, boy, but you'll have to do." Growled the boss from behind him.

Trowa dropped the sword in his hand and sighed softly, raising his arms. Well, on the bright side at least he'd distracted them enough to let Quatre get away. He supposed that was better then nothing. But now how was he supposed to get away?
