Fullmetal Alchemist

The Bridge Between Two Worlds

By: Serenity

Ch. 1: The Arrival

------------

In an abandoned building: Central, Amestris

"Are you ready guys?" a breathless Ed asked.

This was it. The moment of truth. He had finally found a way to get to the gate in a safe manner to gain more knowledge about the Philosopher's Stone. This was a last resort, he had no other choice, unless he wanted to sacrifice humans to make it. Pushing his golden locks out of his honey colored eyes, Ed surveyed his handiwork. It was perfect. It had to be. The symbols, the formulas, he had checked everything three times. There could be no mistakes, no way to know what could happen. Ed was kneeling in the middle of his transmutation circle. He stood up, and glanced at the people in the room, his supporters, if anything, god help him, should go wrong.

A blonde girl fidgeted nervously on the outskirts of the circle, "Ed, are you SURE this is going to work?"

"It will, and besides Winry, since when did you show concern for me??"

"That's not it! I just don't want to imagine you having to get MORE automail, which means more to break, more for me to look after, and overall, more work for me!" fumed the blonde, Winry.

"Calm down Win, Ed's work is flawless here. I've helped him check over it. Be careful brother. You don't know what the gate could want from you this time as equivalent exchange," proclaimed a suit of armor.

It wasn't really a suit of armor. It was in fact, Ed's little brother, Al, whose soul was attached to the armor as the result of a disastrous attempt to bring their mother back to life all those years ago. He was 16 now, making Ed 17, though many were still mistaken that Ed was the younger brother and that Al, was the famous Fullmetal Alchemist.

"He's right Winry, there's nothing we can do to change his mind, you know how stubborn he gets. The best we can do now is support him and pray for the best," said a raven-haired man.

This man, Colonel Roy Mustang, was the love object of Ed's life, though he didn't know it…yet. He really was a beauty, also known as the Flame Alchemist, his skin was fair, and he had onyx black eyes, which could captivate anyone, male and female alike. He was also Ed's superior, which was another reason he didn't know about the young alchemist's feelings towards him.

He nodded at Ed, "Go on. We're here for you."

Ed nodded back and took a deep shaky breath. He did not want to lose any more limbs to the Gate, but was desperate to find a way to restore Al's body and his arm and leg of metal. He kneeled back down in the center of his creation and motion for the rest of the group to step back, which they did.

He clapped his hands, and touched them to the ground, activating the transmutation circle.

A bright, electric blue light filled the room, tracing everything that was drawn on the concrete floor. Ed was in the center, engulfed by it. For a moment, he felt a feeling of elation.

"It's working! I'll finally be able to find an alternate way of making the stone without human sacrifices!"

But then, like the first time he wronged the natural laws of alchemy by trying to raise the dead, the blue changed to a dark red tinged with purple.

"Shit, no! Not again! This can't be happening again! Everything was right! I can't die! I can't leave Al, Winry, and Roy!"

He screamed. It was a scream that they would all remember, blood chilling, yet determined at the same time. Al, Roy, and Winry could only watch from the sidelines in horror as the transmutation began to take its intended effects.

Ed thought of the three standing there, watching him go to the Gate, knowing that he could never come back.

"No! I'll never leave them! NEVER!"

Then all was black, as three other screams joined Ed's.

Hogwarts: Quidditch field, match between Gryffindor and Slytherin

The cheering in the stands were deafening. Three-quarters of the fans were clad in red and gold, the rest in green and silver. Slytherin was clearly not too popular here. This was one of the most talked about matches of the year. It was the first match between Gryffindor and Slytherin, long rivaling teams. Nearly the whole school had shown up, despite the freezing rain and chilling wind. This would indeed one interesting match, where Madam Hooch would be unable to call all fouls committed.

"Keep looking for the Snitch Harry! If Malfoy finds it before you, we'll lose!" shouted a girl from below the stands with bushy brown hair. A boy with flaming red hair sat next to her, screaming similar things at their friend Harry, seeker for the Gryffindor's.

The score was 70-40, Gryffindor in the lead. A bludger whipped past Harry's head, narrowly missing him and heard a solid smack from behind him as Fred beat the bludger right back.

"Concentrate Harry, you can't afford to let Malfoy win this game. He'll give us endless shit if we lose the first rival game to them!" thought Harry, slicking his hair out of his eyes.

The Snitch had been spotted several times throughout the game by one of the Seekers, but was quickly lost again in the storm. Malfoy was not far from him, watching Harry's movements in case he spotted the Snitch.

Harry squinted, then "Wait, is that it? Is it the-" yes, he had spotted the Snitch! It was a gold glimmer barely noticeable against the rain and clouds. He leaned forward and accelerated on his Firebolt, not looking back to see if Malfoy had spotted it or not.

"Look! Harry's spotted the Snitch!" came a voice from the stands.

Harry sped up, reaching for the Snitch, Malfoy right behind him. As his fingers curled around the tiny fluttering ball, Harry experienced a weird feeling. It was as if he was seeing things as a flip book, disconnected, jerky. There was a brief flash of white hot lightening then the loudest crack of thunder he had ever heard, as if the storm was tearing the heavens themselves apart.

A whistle was blown, signifying the end of the match, Gryffindor had won and a roar went up from the stands. As the players landed, the storm quieted, as if it were content with something. Harry landed, only to be surrounded by his friends and fans.

"That was a great game mate! That dive for the Snitch was unbelievable!" exclaimed Ron clapping him on the back. Hermione, the girl standing next to him, agreed. Fred and George, the twins, fought their way through the crowd to Harry.

"Party in Gryffindor dorms tonight!" roared Fred.

A cheer went up and Harry grinned. Those parties were…famous, for the illegal food and drinks the twins managed to somehow smuggle into the school. It was also famous for students hooking up with each other…he'd be looking forward to tonight.

"Dumbledore, Dumbledore!" shouted a large disheveled man.

"What is it Hagrid?" asked Dumbledore.

"Somthin weird just happened! I was in the Forbidden Forest, tracking unicorns when there was a flash of light and when I could see again, there were four strangers in the middle of the woods! I checked their pulses, they're still alive and they don't seem to be harmed. There are two boys and a girl, around the same ages and a grown man!" Hagrid told in a breathless rush.

Frowning slightly, Dumbledore told Hagrid to lead the way. The trio looked at each other, with the same curious, wondering look on their faces. Harry shrugged, he'd find out what this was about later, now, it was the time to celebrate!

Hogwarts: In the infirmary

"Lights…pain…a pain worse than loosing his limbs to the gate for the first time…a blackness…a whisper in his ear saying he got what he wanted…for a price…"

Ed groaned. His body felt like it was on fire. He cracked open his eyes, revealing two slivers of gold beneath his eyelids. He groaned again, shutting them to keep out the blinding light.

"Where am I? The last thing I remember was that something went wrong with the transmutation circle…Oh god…Al, Winry, Roy!"

His eyes snapped open and took in his surroundings. It seemed that he was in a hospital of some kind. He glanced around him and breathed a sigh of relief when he spotted Winry and Roy.

"Wait…why are they here?! Oh god, don't tell me that whatever happened to me happened to them too! What if…Al's circle was broken?? I don't see him! Fuck! I'll never forgive myself if something happened to him!" Ed was on the verge of panic when he heard voices. Looking for the source, he spotted an office, with two figures silhouetted against the light.

"Dumbledore, what do we do with these strangers? They don't appear to be from this area…or time period!" whispered a concerned Madam Pomfrey.

"Don't worry Poppy, after they wake up, I'll ask them some questions. Until then, treat them as guests but keep an eye on them. I'm not sure when they'll awake…it's been two days now. Though most of their injuries are healed, they're still unconscious," said Dumbledore.

Madam Pomfrey nodded, then opened the door and stopped with a surprised look at Ed, who was fully awake and sitting up by now, looking around at him.

"Oh my! You're awake! How are you feeling? We tried giving you some potions, but your body rejected them." asked Pomfrey.

"Err…" came a croak. Ed cleared his throat and tried again. "My body hurts like hell. Where am I? And where is the suit of armor??"

"You're in the infirmary at Hogwarts School of Witchcraft and Wizardry. You've been here for 2 days. I'm the nurse and I've been looking after you. There was no suit of armor…" explained Pomfrey.

"No suit of armor? No…don't tell me…I can't have lost Al! Something must have gone wrong and pulled the four of us through the gate to…this Hogwarts place! If Roy and Winry made it, then Al should have made it too!" thought Ed.

Something troubled must have shown on his face because Pomfrey ordered him to lie back down and get some rest so that he may talk to Headmaster Dumbledore later. Ed looked startled at first that he was being given commands from a woman, but complied. She gave him a drink, which was supposed to heal him in a few hours time. Ed took it once he was sure it contained no milk and promptly fell back asleep. Dumbledore settled down next to the chair and studied the strange youth…

A few hours later, now just past lunchtime

Ed woke up, feeling much better. No, he felt better than better…he felt…excellent!

"Damn, whatever that woman gave me did its trick. What was her name again? Pom-fry, Pomp-free? Oh well, I'll learn it later"

It was now that Ed noticed the wizened man sitting next to him. He stared into those twinkling blue eyes behind half moon glasses and was surprised to discover that they held only kindness, caring, and concern for him. Eyes with emotion that he hadn't seen since his mother was alive.

"How are you feeling? We weren't quite sure if you would make it. It seems though, that you and your companions will be okay," Dumbledore said.

"Erm…I'm feeling alright…did you um…find a younger boy maybe? The nurse said there was no suit of armor…so he would have brown hair…" Ed trailed off, fearing for the worst.

"Do you mean him?" Dumbledore pointed to a bed that Ed had not noticed before.

Sleeping in the bed was indeed Alphonse Elric. Only, he was in the flesh. Gone was the cold, hard, unfeeling metal body that was he.

"His body…he has his body back!! Wait, does that mean?…" Ed pulled out his right arm from underneath the sheets and was disappointed to see that it was indeed still metal. He checked his leg, and it was still metal.

"That's weird…how does Al have his body but I still have my automail? Oh well, it doesn't matter. All that does matter is that we're all here, safe, and Al has his body! I'll figure out what happened later."

"Have any of the others woken up yet?" asked Ed.

"No, but we suspect that they should be waking up soon. Why don't you rest a bit more and when the other three wake up, you may come to my office so we can figure out what happened exactly."

Ed nodded, fell back against his pillow, and slept.

An hour or so later, sometime before dinner

Ed woke up and was confused by his surroundings at first. Then, everything came back to him in a rush. The accident, this school, and…Al's body! He bolted upright, jumped out of the bed he was in and went to see Al, who was also awake by now, as were Roy and Winry.

"Big brother! My body! I have my body back! But how can that be?? You still have your automail! What price did you pay in equivalent exchange to get me my body? " exclaimed Al.

Ed laughed, "Whoa! Calm down Al! One, I don't know how you got your body back or how I still have my automail. But it seems that everything else in me is in working order, so I'm not sure what the price was I had to pay."

"Ed! Finally, you're awake, geez! Do you have ANY idea how loud you snore?? And look at your automail! I'm gonna have to completely repair them again! Thank god you didn't lose any more limbs!" exclaimed Winry, though it was plain that she cared for him deeply.

"Winry! Calm down geez, I hope you lost that wrench of yours in the process of us getting here! And I don't snore as loud as you!" He ducked when he saw her reach for her back pocket where she always kept her trust wrentch. However, he was saved by Roy (who woulda though that eh?).

"Fullmetal, it seems that whatever caused Al to regain his body has also wiped mine and Winry's body clean of any blemishes, scars, or old injuries that we had," said Roy, who was sitting up in bed. "It seems that anyone who was on the outside of the circle was 'fixed'. Too bad for you eh? If you were outside with the rest of us, you might not be such a shrimp anymore!"

"WHO'RE YOU CALLING SO SHORT THAT YOU COULDN'T EVEN SEE ME WITH A MAGNIFYING GLASS?!?!" roared Ed, turning red in the face and was about to rush Roy when a soft cough caught his attention.

"Damn him, no matter how hot he looks shirtless, the man is still a bastard. Yet…I…still love him…"

"Now that you're all awake, shall we proceed to my office?" Dumbledore asked, quite amused by Ed's reaction.

Ed, still grumbling, agreed. The four of them followed Dumbledore. The halls were very empty, and when he asked, Dumbledore told him it was because all the students were either still in classes or getting ready for dinner.

They continued to follow him until they reached a stone gargoyle in which Dumbledore stopped in front of.

"Lemon drops" and the gargoyle jumped to the side.

Wide eyed and slack jawed, the four of them followed Dumbledore down a winding staircase and into his office. If they were surprised by the gargoyle before, then they were stunned by the office. It was rich and lush, full of odd, silver, tinkling items. Of which some were emitting smoke, making music, or just sitting there looking pretty. On the walls of the office were paintings.

"No," thought Ed, "paintings wouldn't cover it. The people and things in them are moving! They're going from one frame to the next and talking with the people in there! It's as if they're real people, not just paintings hung on a wall. What the hell is this kind of place?? It's not any form of alchemy I've ever seen!"

A lone musical note pierced the air, sad, lonely, and beautiful. Startled, the group turned to the source and saw a crimson colored bird with a few gold feathers and a gold beak. It peered at them with knowledgeable eyes. Ed shuddered, he felt as if the bird knew all his secrets from that one glance into its eyes.

"Ah…I see Fawkes has caught your attention. Well sit down now, all will be explained in due time."

"Sit where? I only see one chair old man," snorted Ed, which earned him a slap on the back of his head from Winry.

Dumbledore only smiled, waved his hands, and poof! four chairs popped out of nowhere that looked just as comfortable as the one behind the desk. Ed nearly toppled over with this new surprise and only Al holding him helped him keep his balance. They took the seats facing Dumbledore and found that they were indeed quite comfortable.

Dumbledore smiled at them and said, "Why don't I tell you everything about Hogwarts and this world, and then you tell me about your world Ed? I think it's quite clear that you're from a different time or place."

Ed considered this for a moment, then nodded. Dumbledore proceeded to tell all of them about magic, the school, the rise and fall of Voldemort, boy named Harry Potter who was the only one to survive Voldemort's killing curse, and all of the events to get him caught up to date with the wizarding world. Throughout the narration, Ed, Al, and Roy were stunned, not quite able to believe that these people could perform something similar to alchemy except that they weren't governed by equivalent exchange.

When Dumbledore finished, Ed nodded numbly and started to tell him about Amestris, with the others helping him when his memory faltered. He told of his childhood, how his bastard of a father left them, and the death of his mother. When he came to the part of his forbidden human transmutation, he hesitated, glanced at Al, who nodded, before telling Dumbledore of his grave mistake. The mistake that changed his and Al's lives forever. He told about joining the military to find the philosopher's stone to restore their bodies and make right what was wronged. He told of his adventures, the Homunculi, and the experiments he performed in order to come up with the transmutation circle that brought the four of them to Hogwarts. Roy, Winry, and Al all added in their details as well. By the time everyone was finished, it was well into the evening and the sun was starting to set.

Dumbledore nodded, considering all of this new information. "This Gate you tell me of…I believe the witches and wizards here have discovered something about it. We know it exists and it's where we get our power. For us, the Gate chooses certain individuals to be graced with its power. The power we receive are then channeled through wands to perform deed with works or incantations spoken. I'm not sure if it's the same Gate you mentioned, but it sounds that way. However, no one on this side of is has ever journeyed to it. Those that did come back either mentally unstable or only as limbs."

Ed nodded, taking all this information and storing it in his brain to be examined later. But now, he was tired. Very tired. Dumbledore noticed this and kindly suggested that they go and rest. He waved his hand again and some sandwiches and drinks appeared before them. They were startled, but dug in once everyone realized how hungry they were. Waving his hand again, the plates and cups disappeared.

"Now, where shall we be staying? You are not students here, so you have no proper house to go to. Now, there is a section of the school that is much like the dorms of the other Houses. There, you will find two rooms, with a shower, bath, and toilet in each. Joining the two rooms will be a common room with some seats, sofas, desks, and a fireplace. I'll have someone come down and lead you to your rooms. Tomorrow morning, someone will be sent and take you back down here."

They nodded, and at the same time, the door to the office opened, and in walked a woman who carried herself with dignity and commanded respect from others.

"Ahh, Minerva, I'm glad you got my message, if you would be so kind to show these four to their chambers, I'd be happy." Dumbledore said.

Minerva glanced at the four, and nodded and started a brisk pace towards their rooms. Ed tried to memorize the path, but they took too many turns and plus, the stair cases moved!

"Ignore the paintings, and don't believe anything they say," advised McGonagall.

They nodded, and stopped paying attentions from the paintings that cried out at them. After what seemed like forever to their tired bodies, they turned down a corridor and finally stopped in front of a wooden door.

"Here are your rooms. I hope you have a good nights' sleep. I'll be coming to fetch you in the mornings. I must return to Dumbledore's now, so good night." And with that, she turned and with a fluttering of robes, walked back the way they came from.

Ed nodded at her retreating back side, opened the door and gasped. The room was lavishly decorated. The sofa's and couches looked plush as if no one had ever sat on them, yet there was not a speck of dust in the room. There was already a fire in the fireplace, casting a merry glow in the warming room. There were two doors on the sides of the room.

"Big brother, if you don't mind, I'd like to share a room with Winry…" Al said, provoking a blush to grace Winry's cheeks.

Ed nodded, grinning. He was still getting used to the fact that Winry and Al were dating, even though it's been about 6 months now. He waved them off and only when did they leave the room did he realize the situation he just put himself in.

"Fuck. What'd I just do?? Now I'll have to share a room with Roy. Not that I wouldn't mind, but he doesn't know how I feel! Oh man. This is not good. He's completely straight! I can't count how many women he's had. I wonder if he's experienced?…No! Shut up! Now is not the time for those kinds of thoughts! Besides, he'd never be interested in someone like me!"

Ed's groin had started tingling when he though of how experienced Roy might be. Lucky for him, Roy too was thinking and didn't notice the slight swell in Ed's skin tight leather pants.

"Hmm…so I'm sharing a room with Ed am I? This definitely has its possibilities. I'm not quite sure how he thinks of me, so I'll have to keep acting like a superior to him until I'm positive. I wonder if he's gotten any ass? Or does he prefer pussy? Actually, I'm not quite sure…guess I'll just have to find out…hehehehe"

Roy had no trouble accepting the images of him and Ed flashing through his mind. He stood there with a glazed look in this black eyes of his, growing horny from the thoughts. His thoughts were interrupted by Ed, who cleared his throat and indicated that they should probably get to bed. He followed him to the other room, admiring Ed's ass and the way it moved in those tight, tight leather pants of his.

Ed flung open his room, and for the god knows how many times it is now, was surprised. There was one king sized bed in the middle, draped lavishly with midnight blue silk sheets and an array of pillows arranged on the top.

He gulped, "What the fuck? Only one bed?? How the hell am I supposed to hide my feelings now when we're supposed to share ONE bed?!"

Roy saw this and snickered quietly to himself. He'd have fun alright…oh yes he would…

He cleared his throat, "Ed, do you plan on standing there until morning gaping at the furnishings, or do you plan on going to bed?"

Ed mumbled something that sounded like "…take the bed, I'll sleep on the floor."

"What the hell are you talking about? We can share a bed, it's not a problem with me."

"Fine, whatever, just try not to molest me while you sleep."

Roy laughed and moved to the opposite side of the bed, pulling the sheets down. He laughed because, that was exactly what he had intended to do. Ed did the same thing and removed his boots, socks, his red coat, gloves, and state watch and placed them in a pile by the foot of the bed. He turned around and was shocked (surprise surprise) once again by an image of Roy in his boxers, and only his boxers.

"Close your mouth Ed, this is how I sleep. I hope it doesn't bother you," Roy snickered, flashing one of his trademark smirks that could make women melt at his feet.

Ed blushed furiously, which Roy found incredibly cute. Mumbling, he unbuckled his leather pants and slid out of them and then removed his tight black tank top. He turned back to Roy, facing him in only his boxers as well.

He smirked at Roy's surprised look, "Well two can play at that game Mustang. I know now that you must feel SOMETHING for me, from the looks I've seen you giving me, no matter how many women you get."

Roy was surprised by the boy, he hadn't been expecting that from Ed at all.

"Hmm…this could be interesting…very interesting…"

With a casual shrug, he climbed between the sheets, marveling at the feel of pure silk against his bare skin. He turned to look at Ed, who was taking his golden locks out of his customary braid.

Ed tugged the elastic out and ran his fingers through his silky hair, ruffling it up a bit. His hair fell in layers down to his shoulders, and his bangs framed his milky, porcelain like face. His hair was slightly wavy from being in a braid for so long, he noticed. His eyes were closed while he ran his fingers through his hair, enjoying the feeling, and completely oblivious that Roy was watching him with lust burning like flames in those onyx eyes. Ed opened his eyes, saw Roy staring at him, blushed and licked his lips, which drew attention to how red, soft, and shapely they looked. Embarrassed that Roy had caught him primping, he quickly jumped into bed, witch his back facing Roy. He had completely missed the lust in Roy's eyes.

Roy was entranced by the sight in front of him. He had watched Ed take his hair out and imagined it was he running his hands through that hair when Ed was doing it. He stared at his body, memorizing every line, every curve, because he was still unsure if he would ever see Ed in that state again. When Ed licked his lips, Roy couldn't help but notice how amazing they looked. Ed had climbed into bed and turned the light off that was attached to the wall by his side.

"Goodnight Roy," was all he said.

"Goodnight Ed," Roy said as he too turned the light off, plunging the room into darkness. Roy watched Ed, heard his breathing become more relaxed and deeper, until he was sure Ed was deep asleep.

"I guess he must be very tired from all the events that had happened. I can't blame him. God knows what thoughts went through his mind as the Gate pulled him through."

With the knowledge that Ed was fast asleep, Roy pulled Ed into his embrace by his waist, until they were spooning in the middle of the bed, surrounded by silk and pillows. Ed sighed and snuggled into Roy, which prompted him to tighten his grip around Ed's waist. It was in that position that Roy finally fell asleep, curled around the one he loves.
