This is an FMA/Harry Potter cross over. No, I don't own any of the characters, blah blah blah.

Rated M for language, lemons, and limes in later chapters!

Pairings: EdxRoy, bits of AlxWinry, HarryxGinny, and RonxHermione.

Italics are the character's thoughts!!!

Summary: Ed finds a way that will take him to the gate to obtain knowlodge about the Philsopher's Stone. That plan backfires and drags him and his friends into the world of Harry Potter. He must adjust to life there, protect Hogwarts and when the time comes, decide which world he will be in to save from near destruction.

Limes/Lemons in this chapter! Most likely between EdxRoy. They're very, very graphic so if you don't like that kinda stuff, then don't read!!

On with the story, yay!

Ch. 2: A New World

Hogwarts: Ed and Roy's room, early morning

Ed sighed, snuggling into the bare chest he was pressed up against. He took a deep breath, inhaling the other person's scent…and he smelled good Ed decided. Then he became more awake.

"What the fuck? Who the hell could I be pressed up against? Let's see…I think I was sharing a room with Roy…Roy…ROY?!?"

His honey golden eyes snapped open and stared at the still sleeping man. Afraid that he would wake up any moment, Ed pulled back, only to discover that one of Roy's arms were wrapped tightly around his waist. Which drew attention to something else in his waist area. His usual morning boner. And the head of that boner was resting on Roy's arm. The arm which Roy decided to shift at that moment, moving it down a bit so that it rubbed the underside of Ed's cock.

Ed stiffened, and stifled a groan that threatened to escape those cherry colored lips. Pre cum leaked out and left a small stain near the waistband of his plaid boxers.

"Shit…I can't stay here in this position like this…what if Roy wakes up?!"

Ed concentrated on making his boner go down, but to no avail seeing as how Roy would shift every thirty seconds or so, making another drop of pre cum leak from Ed, adding to the slowly growing stain. Stifling another moan, Ed slowly got out of the bed, making sure Roy remained asleep the whole time. He grabbed a towel that had been left there for the two of them and headed into the bathroom to take a shower.

The moment the door to the bathroom shut, Roy cracked an eye open and grinned evilly.

"My my ,it seems that Edward Elric is easy to please. Those moans he tried to conceal were so fucking sexy. Feeling the stain on his boxers was even better! Damn…I don't think anything so small has ever made me so horny."

He reached underneath the sheets and gripped his throbbing boner in his hand and gave it a firm pump through his boxers and let out a moan. After meeting Dumbledore last night, he knew this was a safe place and allowed himself some pleasure. Roy slipped his boxers off and snuggled into the silk sheets, reveling in the feeling of silk sliding over his dick.

He spat in his hand and started massaging the tip very lightly, occasionally letting out small moans of pleasure. He gripped himself in one hand while the other went down to cup and play with his heavy balls. He started pumping in slow motions to prolong his orgasm. Just the thought of Ed in the showers probably doing the same thing was almost enough to make him cum right there. He held back with a groan and sped up his actions a bit. Roy was breathing heavier and there was a light sweat forming on his body. His hips started thrusting to meet his pumps and the sound of flesh slapping flesh could be heard. He started pumping faster, pre cum leaking freely down his engorged cock and running down his balls. His back was arched and a few whimpers escaped his mouth.

He was sweating now, and his fist was flying up and down his penis. He was close, very close. And then it happened. His balls contracted and he squeezed his eyes shut. Roy could feel his cum traveling up his cock and the first spurt shot up and into the hand he had moved there to catch it all so as to not leave too many stains on the luxurious sheets. String after string of hot white cum splattered into his hand. Finally, the last of his intense orgasm leaked from his slowly softening dick. He brought his hand up and examined all the cum he had collected, and slowly licked it clean, imagining it was Ed who was doing that.

At the same time, Ed was taking a scorching hot shower. He was still hard, still leaking, so he rubbed his well-developed dick slowly, up and down. In here, he could groan as he pleased, knowing the sound of the water would cover any major sounds he made. A few minutes later, he watched as his cum slid down the shower wall, with a satisfied smile. (Yeah. I decided not to go into too much detail or else I'd feel this was a complete porno xD.)

Ed wrapped the towel around his waist and stepped out the door, with the steam curling around him, framing his body.

He paused for a moment, sniffing the air. "That's odd…I swear the room smells like…nah…couldn't be. Roy's still sleeping."

He got dressed and was about to "wake" Roy up when there was a knock on the door.

"Hey Ed! Get your slow ass up! McGonagall is here to take us to Dumbledore's office!" came Winry's voice. She never was a morning person.

"Coming!" Ed replied.

He turned back to the bed and was startled to see that Roy was awake and looking for his clothes.

"Y-you! How long have you been awake?! You better not have been spying on me while I was dressing!"

"Calm down Ed. Even if I was awake to see you dress, I wouldn't have been able to spot you anyway, shrimp," replied Roy with a smirk.

"WHO'RE YOU CALLING SO SHORT HE COULD BE COMPARED TO BITE SIZED SEAFOOD?!"

He was just about to charge him when a familiar item collided with his head, making a familiar thud. Winry walked into the room, stooped down to pick up her wrench, and stalked out. She was not a morning person. Ed sat up, grumbling and rubbing the sore spot on his head. He cast Roy a glare, who chuckled, before walking out the room. Sitting in the common room was Al, Winry, and McGonagall. They chatted while Roy showered and got dressed.

"Ed, Dumbledore would like to talk to you and the others, about your stay here and what will happen," said McGonagall.

Ed nodded, he had the same thoughts himself. He needed to ask Dumbledore a few questions about the magic in this world. They chatted idly until Roy finally stepped out into the room.

"Follow me please."

The group followed her through the vastness of the school, once again completely lost. By now, it was around breakfast time, and there were quite a few students in the hall.

"Hey! Are those the strangers that dropped in?…"

"Look at that guy with blonde hair!"

"Damn that girl is hot!"

Those students were quickly silenced by a look from McGonagall. However, they continued to point in stare, marveling at the simple beauty of the group. Finally, the arrived at the same stone gargoyle which leapt aside when McGonagall said "Lemon Drops".

She waved them in saying, "Go on, he's waiting for you guys. I need to get down to breakfast. I'll see you there." And with that, she left.

They stepped into Dumbledore's office and was once again amazed by the sight. In daylight, the office was even more spectacular. Items gleamed and sparkled, the sunlight filtered into the room, lighting it up. Fawkes was bathing in the light, which lit his feathers up in colors of flame and cold, as if he was actually burning. At last there was Dumbledore, sitting behind his desk, looking serene and calm.

"Ahh, good morning, I hope you all had a good night's sleep," he said.

A chorus of "yeah's" and "excellents" were his reply.

He smiled and waved his hand, "Have a seat."

Like last night, four plush looking chairs appeared in front of them. They sat down and Ed immediately began to bombard Dumbledore with questions.

"How did the Gate take us here? How will we get back? CAN we get back? Just what is this place? What am I, we, supposed to do here?…"

Roy, Al, and Winry all had exasperated looks, they knew that once Ed started asking questions, they won't stop.

Dumbledore laughed, a small tinkling sound, "Calm down, I'll answer all of your questions in due time. I don't know how the Gate bought you here, I'm guessing an alchemic equation went wrong. If there is a way here, there must be a way back, though I've heard of no such feats. If you can get back, I'm guessing it would be the same way you got here. This is Hogwarts, in England, where we teach special people magic. And, what you are to do here, is exactly what I wanted to discuss with you this morning."

For once, someone had answered all of Ed's questions without appearing angry. He looked surprised and stopped his rush of questions, eager to discuss what the group was to do at Hogwarts.

"Now, Al, Winry , and you Ed, will not become official students, as I'm sure you will only stay with us until you find a way home. However, if you like, you may take lessons with our students here, after being first evaluated for your skill levels. Roy, if you're interested, you may teach a course on Amestris, for those students that are interested."

Ed nodded, considering this before turning to the other three, "Well, what do you think of that? I personally can't think of anything else we could do."

Al and Roy agreed, Winry however, was unsure. "Um…I've never done any alchemy in my life. How will I be able to do magic? All I am is Ed's mechanic, and from what you tell me, there's not much that I could do."

"Winry, this world seems much more advanced than Amestris, you could research all the materials here to make Ed better automail!" suggested Al.

Winry was extremely enthusiastic about that idea, and spent the rest of the meeting dreaming of all the things she could make.

"Ed, Winry, Al, Roy, there's something else I need to ask from you. You remember that boy I told you about last night? Harry Potter? It would be nice if the four of you could, perhaps, watch or guard him during your stay here. Voldemort has returned last year and I fear for his safety."

Ed scowled at that, he didn't like the thought of being someone's babysitter.

Al and Roy however, had no problems agreeing and Al nudged Ed who finally relented.

"Yeah, okay, we'll do it," he mumbled.

"Excellent!" beamed Dumbledore, "Now, I believe all current issues are settled. If you like I could lead you to the Great Hall where the students are eating right now. I'm sure you're all very hungry. After eating, I can have someone take you to Diagon Alley to get materials that you'll need during your stay here."

They nodded eagerly, for the first time realizing HOW hungry they were. They followed Dumbledore through a confusing number of turns to get to the Great Hall.

He noticed their completely lost looks and chuckled, "Don't worry, you'll find your way around the school in no time."

They walked into the Great Hall and was stunned once again. There were four long tables, filled with students chatting and eating. Candles floated in the air, though today there weren't lit for there was sunlight streaming in from the glass rooftop. A few heads near the door turned and looked at them. Then the whispering started, which traveled down the length of all four tables in no time.

"'Ey Harry! Did you hear? Those strangers who appeared in the Forbidden Forest are here!" exclaimed Ron.

Harry was about to look when a screech caught his attention. The morning owls are here.

Ed, Al, Winry, and Roy were standing at the door when a rush of owls flew by overhead.

"What the hell?! What's going on??" exclaimed Ed.

"It's the morning owls. Here, we use owls as our mail system. They're quite intelligent and reliable. Many students choose to keep them as pets here," explained Dumbledore.

"Jeez, this place gets nuttier and nuttier every second," mumbled Ed.

Dumbledore chuckled and pointed to one of the tables garbed in red and gold, "There. I think you'll make good Gryffindors. Harry and his friends should all be there. After you're done eating, you'll be able to go to Diagon Alley. Now, as you're not official students here, I'm unable to stop you from the leaving the school, but I advise you to stay here until you learn some magic."

They nodded, spotting the trio among the other students who were now opening their mail. They moved towards the table, ignoring the sudden hush that came about. Ed led the way, his golden eyes blazing with confidence and sat down next to Harry. The other three sat next to Ed. The table was laden down with all different foods, sausages, bacon, bread, butter, jam, croissants, pumpkin juice, orange juice, milk, and others that they couldn't identify right away. The four dug in eagerly, never having been faced with such a feast.

A snicker came from a table away, "Well, looks like we know that the newcomers are complete losers. They're probably friends of that Potter freak. Look at that kid, I've never seen such a shrimp in my whole life!" shouted a platinum blonde boy. His hair was slicked back and he sat there with an arrogant look on his face.

Ed put his fork down, slowly turning red. He got up, with a fiery look in his eyes and turned to the speaker. Al, Winry, and Roy exchanged looks, this time, no one was going to stop Ed. Harry and his friends just stiffened, used to the snide remarks of Malfoy, but glanced curiously at Ed, who had a stony look on his face.

Ed walked to the Slytherin table, all in green and silver and stood in front of Malfoy. He wasn't going to bother yelling, not this time. He just wanted to wipe that smirk off the guy's face. He drew back his right arm, smashed it into his face, turned around and sat back down next to Harry without saying a word.

A silence hung in the air, Malfoy sat up, holding his hand to his nose, "YOU! You're going to pay for this! Once my father hears of this, your whole life will be ruined!!" He stood up, drawing his wand, but was quickly intervened by McGonagall.

"Malfoy. Did I just hear you threatening someone who is not even a student here? I think that calls for 20 points from Slytherin," she said smoothly.

Malfoy turned red in the face and sat down grumbling while snickers ran down the length of the tables.

Winry sighed, "Ed, you don't even know the guy, did you HAVE to deck him?"

"Of course I did!" Ed snorted.

Al and Roy merely exchanged amused looks.

Hermione who was sitting next to Ron, rolled her eyes, "Great, looks like we got another trouble maker."

Ron and Harry however, were ecstatic to see Malfoy get punched in the face at point blank range.

"Oi mate! That was a great shot! Man, I wish I could have done that myself!" exclaimed Ron, with Harry nodding.

"RON! If you do that, not only will you earn detentions, but you'll get house points deducted from us!" scolded Hermione.

"Errr…" was all Ed could say to this exchange.

"OH! Pardon me, I'm not sure where my manners are this morning, I'm Hermione, that's Ron with the red hair and that's Harry with the black here."

"Nice to meet you, I'm Ed, that's my brother Ed, Winry's the girl, and Roy is the perv over there," Ed replied, which earned him death glares from Roy.

"That's cool! How old are you guys?" asked Harry.

"I'm 17, Al and Winry are both 16. Roy is 21." (Yeah. I lowered his age so I wouldn't feel like a pedophile writing lemons between them xD)

They made some small talk until Ed, Roy, Al, and Winry were done eating, and wondered where they were supposed to go to get to Diagon Alley. At that moment, a giant walked up to the four. Literally. It was the biggest man any of them had every seen and they merely sat there, gaping.

"Ed, Al, Roy and Winry?" rumbled a deep voice.

"Th-that's us!" stammered Ed.

"Good. M'name's Hagrid and Dumbledore's asked me to take you lot to Diagon Alley to get a few supplies," Hagrid said.

All Ed could do was nod numbly at Hagrid, who motioned them to follow him.

"Bye guys, see you at dinner tonight?" called Harry, who received four nods in reply.

"They seem very nice, even if Ed did hit Malfoy. Where do you suppose they're from?"

"Dunno 'Mione, I don't think they came from a place that had magic though, from the looks on their faces.

The three of them shrugged and the topic was changed to Quidditch, to teachers, to schoolwork.

Al, Winry, Ed, and Roy followed Hagrid down to Dumbledore's office, only to be faced with a…thing. There was no other word to describe what was in front of them. There was no way it could be a woman, it was too short, too fat, too frog like, too ugly to be human. Sadly, it was a woman, and her features were squashed, she had small beady eyes set in a wide chubby face. Her fingers were incredibly fat, stuffed into gold rings and she wore the most ridiculous purple suit that was ever made.

"Hem hem," she croaked, "are these the strangers you were just telling me about Albus?"

"Yes they are Dolores, delightful aren't they? Hagrid's taking them to Diagon Alley today by Floo."

Dolores sniffed, looking at them, "You think you can trust this group of rascals? They ought to be apprehended and taken to the Ministry at once!"

Ed glowered at that comment but restrained himself from doing anything too rash that might mar this woman's features even further.

"This is my school, Dolores, and because I can trust them, so can everyone else. Now, if you'll excuse us, I must explain how the Floo Network works to them."

With one last sniff, she stalked out the room, tossing them a dirty look.

Dumbledore sighted, before going to one of the shelves to pick up a pot filled with a green powder.

"This, is Floo powder. All you do is throw it into the fire place and state very clearly where you wish to go. Don't hesitate! The journey will be quick, although you'll be a bit dusty when you walk out the other fireplace. Take a pinch of this powder, throw it in, step into the fire, don't worry, you won't be burned, and say 'The Leaky Cauldron'."

The four seemed a bit startled that they had to go into a fire, but were somewhat reassured after watching Hagrid do it and disappear into the green flames.

Ed was next, he took a pinch of the powder, stepped into the fireplace, threw it, and watched the flames turn green.

"Fascinating. I wonder if the flames turn green due to an alchemic reaction? I'll have to find out more about the magics of this place."

"The Leaky Cauldron!" he pronounced clearly.

He felt a weird sensation, and felt as if he was falling through nothing, spinning around. All of a sudden, he landed, in a different fireplace. He stepped out, coughing and brushing the ashes off his coat.

"I never wanna do that again," he mumbled.

He noticed his surroundings for the first time. He appeared to be in a bar, maybe an inn of some kind. There were men and women sitting at tables, drinking, eating, or reading newspapers with moving pictures. Ed knew that they were all witches and wizards. He heard a thump behind him and found Al sitting in the fireplace, looking thoroughly confused. Ed pulled him up and pulled him aside, just in time for Winry to land, quickly followed by Roy.

"Damn, the bastard even manages to look good covered in ashes."

Ed was transfixed by Roy, who was wiping ash off his face and running his hands through his silky hair to get rid of any that might have been caught. He saw Ed staring at him and smirked, which caused poor Ed to blush furiously. Thankfully the room was dim enough and Ed was still soot covered enough, to hide his blush. Roy walked over swiftly, licked his thumb, and wiped the remaining ashes off of Ed's face, revealing his crimson colored cheeks underneath.

Ed stammered, "G-get away from me! I know how to clean myself!"

He turned away, walking towards the bar where Hagrid was seated. The three exchanged amused glances behind his back, knowing that Ed liked Roy. And Roy himself knew for sure now that the younger alchemist had a crush on him.

"Hmm…tonight will be fun…" he thought with a smirk.

Ed was talking to Hagrid, who motioned him and the other three to follow. They went out a back door and entered a tiny backyard with a metal garbage can next to a brick wall. Hagrid walked up the wall, pulled out an umbrella, and began muttering to himself, tapping the bricks as he went along.

They stared at him, wary of what would happen next. Hagrid tapped one more brick and stepped back, with a pleased smile on his face. The bricks then began to fold back on themselves, creating an archway big enough for Hagrid to walk through without having to stoop. Their jaws dropped as they stared at what lay beyond the arch. It was a street, packed full with people and the sides were lined with colorful shops with things whizzing, banging, and moving in the windows, advertising that store's goods. Hagrid motioned them to follow and led them through the crowd of people. They kept up with him easily, for he parted the crowd wherever he went. A few people greeted him before going on their way. He led the group to a building, with a sign that said "Gringotts Wizarding Bank".

"We'll have to stop here to withdrawal some money from the account that Dumbledore set up for students," explained Hagrid.

They followed him inside, and gazed at the marble decorations and statues that lined the hallway. Hagrid went up to one of the counters manned by a creature that none of them had ever seen before.

Hagrid whispered, "The bank is maintained by goblins, never try to steal anything from this place. You'll get lost in it and most likely will die from starvation while you try to wander your way out."

To the goblin he said, "Yes, I would like to extract some money for Edward and Alphonse Elric, Winry Rockbell, and Roy Mustang from the Hogwarts safe for students."

With that, he reached into one of his numerous coat pockets, searching for something. However, something the goblin said stopped him.

"Edward Elric eh? Hmm…" he glanced down at something, back at Ed, and back at whatever he was looking at before, "Yes, I have instructions left here for you, Fullmetal Alchemist. This key will get you into your vault, where you will be able to make withdrawal and deposits. Try not to lose it, now, if you'll follow that goblin over there, he'll take you to your vault, number 723." He handed a shocked Ed a small glittering key.

Ed looked alarmed, he turned to Al, Winry and Roy, "Who could have left me this? And how do they know I'm the Fullmetal Alchemist?? They were obviously anticipating me coming to this bank…but Dumbledore said no one has ever successfully traveled between worlds using the Gate!"

They looked alarmed as well, but none had a reasonable solution.

"Whoever it is, they know too much about you brother, we'll have to learn the magic here in case we need to defend ourselves. We should keep an eye about for anyone suspicious looking that might be from Amestris."

They nodded, and looked at Hagrid, who seemed just as perplexed as they did.

"If I were you, I'd have a talk with Dumbledore when we get back," Hagrid said.

They agreed to that and went over to the goblin that was to take them to Ed's new vault. They got into a train cart and with the push of a lever, they were off. They were plunged into a dark tunnel, riding on tracks. The only light came from torches that lined the walls of the rock tunnel. They accelerated to a frightening speed, making sharp turns every 30 seconds or so. The ride lasted bout 5 minutes, but in that time, they had taken enough turns to make Ed lose count.

"Hagrid's right, someone would have to be insane to try and rob from this place."

The cart slowed and stopped in front of vault 723. The five of them got out of the cart, wobbling a bit, and Hagrid looked just a slight shade of green.

"Never did like riding those carts," he mumbled.

The goblin hopped out of the cart with a lantern and landed nimbly on his feet.

"The key," he said, holding out his palm.

Ed gave him the tiny key and the goblin inserted it into a hole on the door of the vault. There were a series of clicks and the door opened slowly. The goblin waved his hand and the torches on the inside wall were lit. The light revealed a magnificent sight. There were small mountains of gold coins, heaps and mounds of silver, and piles and piles of scopper coins. Ed's jaw dropped, he had never seen this much money before in his life, and with a start, he realized that it was all his. Roy, Al, and Wnry were just as shocked as they stepped into the vault.

"Ed, now you'll just HAVE to buy stuff for me so I can make more automail!" Winry squealed.

Still shocked, all Ed could do was nod numbly. "Who would leave this must money to me?? Someone must have been to this side of the Gate before…"

Hagrid handed him a soft velvet bag and Ed filled it to the brim with the coins. He asked Hagrid how the money here worked, explaining the values of each. Ed realized that the amount of money he had in this vault was more than some wizards or witches made in a lifetime. After he filled the bag, they took the cart back through the dizzying maze of tracks and back to the lobby of the bank. The goblin bid them good bye and they stepped out of the bank, into the blinding sunlight.
