AN: This fic was the result of some drawings I did where I took the Elric brothers and drew them in Kingdom Hearts inspired outfits. It inspired me to actually write a cross – over story, so here it is, and you may notice that I edited the FMA designs a little based on my drawings, but they still look basically the same. This story is set after KH 2, but before Coded, in the KH timeline, and I've treated the FMA characters like Final Fantasy characters and basically removed them from their own timeline. So you might see some people who are dead in FMA alive and well here (On the basis that: if Aeris can live, so can Hughes!) and some stuff might not make chronological sense. Like, Al has his body, but Ed still has automail. And I'm also using the FMA Mangaverse, so there may be some spoilers for people who haven't read it or watched Brotherhood.

Also, this is my first fic, so go easy on me! Advice and critiques are welcome, but don't flame! And don't get mad if I don't listen.

The darkness was swallowing the world. A typhoon of shadows was closing in around the edges of the city while a second column rose from the center into the clouded sky. Purple lightning flashed behind clouds of pure darkness and strong winds pulled trees and buildings right out of the ground. The laws of physics seemed to vanish as the debris was drawn upwards towards the menacing sky. As the ring of darkness tightened around what was left of the city, the ground began to break apart, revealing a chasm of darkness and ominous light. The strange shadowed creatures that had brought this destruction with them began to vanish as the city crumbled. The keyhole had been opened. The world was lost.

"Sora? Sora!"

"Ugh…"

Sora's vision slowly came into focus and he was hit with immediate confusion. He was staring up at the sky and he could feel the grainy sand of the island underneath him, there was also a dull soreness running through his back. He pushed himself up into a sitting position and dusted some of the sand off. He looked up to see the tree he'd been sitting on only moments before, bent into an awkward horizontal shape, making an excellent bench. This tree, and the tiny island it grew on, was where they had first spoken of leaving their world and where they had been reunited. He would always come here with Riku and Kairi after school to talk and look out over the ocean, as they did that afternoon. But he had no memory of getting up or moving, one second he'd been sitting on the tree trunk, and the next he'd been laying on the ground.

"Sora, are you okay?" Sora turned to see Kairi on his right side, looking very concerned, she'd put her hand on his shoulder as if to support him and keep him from falling back into the sand.

"Uh, y-yeah, what happened?" Sora responded, turning to see Riku on his left with an equally concerned look.

"Well, you kind of…fell…" was Kairi's response. Sora turned to her with wide eyes; he couldn't possibly be that uncoordinated, could he?

"More like fainted." Added Riku, he was looking at Sora in a very serious manner, "You were saying something, then your voice trailed off and you just fell backwards off the tree."

I guess that explains a lot thought Sora but why… "Sora, how do you feel?" Kairi asked cautiously, still looking very concerned. Sora blushed, he didn't like making Kairi worry, and he hesitated for a moment before he answered.

"I-I'm fine! See?" He stood up to prove his point, "I probably just haven't had enough to drink ya'know?" He tried laughing to lighten the mood but it didn't really help. Riku said nothing and Kairi didn't look very convinced. He took her hand to try and comfort her and helped her onto her feet, "Really, I'm okay."

Kairi just stared at him, "If you say so…" she finally said, but she didn't look like she believed him. She gazed out over the water, avoiding looking him in the eyes, "We should go, it's getting late." She let go of Sora, grabbed her school bag and started down the wood bridge that connected the small outcropping with the tree on it to the rest of the island.

"You sure you're okay?" Riku asked, he looked less convinced than Kairi. Sora just nodded. Riku took his own bag and followed after the girl. Sora waited a moment before following. He looked out towards the sun as it began to set. The truth was he wasn't feeling okay, not that he would tell his friends, he didn't want them to worry. But there was a terrible pain in his heart, and a feeling of emptiness and foreboding. He looked up at the sky as the stars began to appear. There were too many to count, and yet he got the feeling that one was missing.

"Has a world fallen to the darkness?" he asked himself quietly. But that didn't make sense, he'd defeated Xehanort and the Organization, so the heartless shouldn't be much of a threat. They couldn't destroy a world unless somebody unlocked the keyhole, and why would they do that? But no matter what he told himself, he couldn't shake the feeling that something big was about to happen.

The next month was very awkward for Sora. Riku and Kairi must have known that something was up because they were constantly keeping an eye on him. They would always walk him all the way home after school, even though their own homes were in different directions, and any time he suggested they go to the island, they would come up with some excuse or reason not to go. They must have concluded that it was somehow connected to his fainting spell. Then again, all the weird stuff that happened to them would usually begin on that island, so there concerns were valid. But Sora was slowly discovering that he wasn't particularly fond of being baby sat all the time, it wasn't like he was in any danger, he hadn't fainted once since that day, and the foreboding feeling had more or less vanished…kind of. His friends were just being paranoid.

And today was no different, as they approached his doorstep he turned to try and talk them into believing that nothing was wrong, for the millionth time. "You guys really don't have to walk me home like this all the time…" his words didn't seem to have any effect on the mood; they were obviously thinking the opposite. He decided to try something else, "How 'bout we go hang out on the island tomorrow?"

"Can't", they responded at almost the same time. Jeez, can't they at least be more subtle Sora thought.

"I got a lot of work to do" Riku said. He was looking off into the distance, or rather; as far down the road as one could see from Sora's front path.

"And I promised Selphie that I'd go shopping with her!" was Kairi's excuse. She smiled innocently, "You can come with us if you want." She offered.

Sora made a face, "Thanks, I think I'll pass. No offense but watching a couple of girls squeal over clothes isn't really my idea of fun." She acted offended but failed to hide her smile. Sora smiled and nodded he turned to open his front door, "It's fine, I'll call Tidus or Wakka and see if they can go." But he knew by the time he called, they would have been talked into saying they couldn't go either, Riku and Kairi were determined to keep him off the island. "I guess I'll see you later then…" They waved goodbye and then turned to leave. Sora ducked into his house and shut the door. He let out a heavy sigh as soon as he couldn't hear them anymore. When were they going to lay off? Even if something did happen, he was the Keyblade Master; it wasn't like he couldn't defend himself.

"Sora? Is that you?" came his mother's voice from the kitchen.

"Yeah, hey Mom."

"Dinner's almost ready, why don't you go change."

"'Kay…" Sora halfheartedly dragged his feet up the stairs to his room. He changed out of his school uniform and lay down on his bed. He let out another sigh. He looked at one of his gloved hands, these clothes had been a gift from the fairies in Twilight Town, and he'd worn them when he'd saved the world. He sighed and put his hand back down. It kind of sucks… he thought, he'd done so much and been a real hero, but so few people knew about it, and almost none of them lived on the destiny islands. And the only ones who did seemed to have forgotten because they were treating him like a helpless child. He turned his head to gaze out the window.

He almost jumped when he saw the sky. It was streaked red and pink by a setting sun, which would have been normal, except it was way too early for the sun to set. He leaned out the window to get a better look; other people on the street were pointing and staring too, so he definitely wasn't imagining this. What was even freakier was that the sun was setting in the wrong place, instead of dipping over the horizon out over the ocean; it seemed to be setting behind the island where he'd fainted all those weeks ago. The island where everything always began.

Maybe it's nothing Sora thought maybe it's just some weird weather phenomenon, or a volcano or something… he remembered seeing an odd sunset as a kid, one that had been caused by volcanic ash. But that didn't really explain the odd timing or location; his arguments weren't holding their ground very well. Then he saw it, a star fell across the sky in a bright streak of white against pink. The people on the street were stopping to make wishes on the shooting star, but he knew better, he knew what it meant.

The foreboding feeling suddenly returned along with a feeling of urgency, he leapt off the bed and dashed out of the room. He took the stairs two at a time and stopped only long enough to open the door before he bolted out of the house. "Sora? Where are you going?" he heard his mom calling after him, but he didn't stop to answer, he couldn't stop. It was as if an invisible force was pulling him, forcing him to go to the island, and he could feel that something bad would happen if he didn't make it in time. When he got to the docks he leapt into his boat and took off without even observing that Riku's and Kairi's were already missing. His arms ached as he paddled at top speed, and he desperately wished that he'd taken the chance to upgrade to a boat with an engine. But the closer he got to the island, the less he had to paddle; the ocean itself seemed to be pulling him towards his destination.

When he pulled up at the island he climbed out of the boat and ran across the beach, toward the secret cave that was hidden under overgrowth and tucked beneath the great tree at the center of the island. That was where the heart was, that was where he had to go.

He ripped the vines out of the way and stormed into the small cavern. The walls were covered in hundreds of drawings, scratched into them with rocks by the island children over the years, and a whole in the ceiling let in enough light to illuminate the decorated walls in an eerie manner. In the back was a large and mysterious wooden door. Many children had tried to open the door over the years, but Sora and his friends knew that it could only be opened in a very specific way, and that it never should be.

Sora was out of breath as he stared at the door in disbelief, the wood was solid, and the keyhole was not there. Was it a false alarm? No! That can't be right! Sora felt confusion and then frustration, what was the island trying to tell him? He turned and left the secret place, trying to understand what he may have done wrong. He was so lost in thought, that he didn't notice the giant black shape hurtling towards him until the very last second.

Donald pushed the gummi ship to go faster. He could hear the engines moan as they pushed against their limits. But they couldn't take their time, they had to get there and they had to get there now. He heard Goofy mumble something from the passenger's seat and turned to look at him. Goofy was sitting uncomfortably and staring at the back seat out of the corner of his eyes. Donald turned to look at the back seat and their new companions who were riding there. One was staring out the window in total awe of the sights, but the other was staring at Donald and Goofy, and had been since they'd met. He looked like he couldn't wrap his mind around their existence and was trying to figure out exactly what they were. Donald turned away from the scrutinizing eyes and focused on driving. It didn't matter that the staring was making him angry or that he wanted to tell the guy off, all that mattered was getting to their destination on time, because if they didn't get their soon, it would be too late.

AN: There's chapter one, not very exciting, I know. There's some action in the next chapter! Hope you liked it.
