Disclaimer: I do not own Fullmetal Alchemist or Harry Potter.

Warnings: This takes place after the Incident of Laboratory but before Ed and Al are found by their teacher. Somehow they are in Central ready for a new mission and yeah Alphonse already dealt with the whole 'My memories are fake' phase. This also takes place before Harry Potter and the Prisoner of Azkaban. The only changes I made to the canon of Fullmetal at this point is that they go to Central and Mustang knows about what happened and is pissed off.

Edward Elric leaned against the wall of his superior's office with a bored look on his face looking half asleep. Beside him laid the armor suit which contained the soul of his younger brother, Alphonse Elric. The day was calm and quiet. In front of him was a desk who belonged to Colonel Roy Mustang, the Flame Alchemist. His onyx eyes moved to the boys as they narrowed suspiciously.

"Fullmetal." He said, greeting the boy by his given State name. The golden eyed boy looked at him, not flinching under the man's unwavering glare. Edward Elric was not amused by the glaring war between Mustang, but unable to do much about it, he simply glared back and refused to back down. Having to come to Central after he had been able to find out things about the Philosopher's Stone was definitely not in his agenda.

"Bastard." Ed said, exchanging the same look that Mustang was giving him. Tension rose in the air as the two men refused to give up the staring contest. Alphonse, who noticed the signs of a battle tried to begin a conversation.

"Colonel, why are we here? We need to find the stone. Why did you call us?" Alphonse politely asked Mustang, whose lips formed a smirk as he saw the short alchemist suddenly stop glaring at him and waited for him to answer the question, his golden eyes wide as he waited for Mustang's reply.

"A new mission was brought in a couple of days ago. I specifically kept it and assigned it to you." Mustang said, waiting for the reaction. He knew better than to think that the boy wouldn't say something.

Three…Two….One.

"WHAT! WE DON'T HAVE TIME FOR A MISSION! I'M NOT DOING IT MUSTANG AND YOU KNOW IT. I DID NOT JOIN THE MILITARY SO YOU CAN STICK ME WITH STUPID MISSION!" Ed exclaimed, obviously mad about the situation. Mustang however raised his hand and said.

"It's a possible lead to the Philosopher's Stone. Now if you can control your temper for a couple more minutes, I'll be able to explain. And if you can't, I'm sure I'll be able to find a suitable replacement, another state alchemist could take your place.

Immediately Ed stopped and stared at him, his golden eyes demanding an explanation. Mustang stared at Ed before giving him a folder containing his mission's requirements and task. Ed took it quickly and began reading the paper, his eyes trailing from left to right. His eyes widened as he finished reading the mission.

"Mustang, you're messing with me, aren't you?" Ed said in a monotone, " Is this your idea of a joke? And babysitting? You want to stick me with babysitting in a magical mountain? Are you serious? I don't have time for this!" he exclaimed, clearly furious.

"Castle actually. But no, Fullmetal, that mission is serious. And I can assure you, those description are not fake." Mustang told him, his own voice indifferent. Al looked from his brother's face to the Colonel's, clearly confused. Ed passed him the folder. He took it and began reading it and soon he became more confused.

"General sir, magic isn't real, it goes against all the laws of alchemy. How could it be possible that there is a school full of 'witches' and 'wizards'?" Al asked, clearly skeptical about the situation. Edward and Al Elric were both alchemist and alchemist did not use magic, it strictly used the Law of Equivalent Exchange. There was no magic or trick to using alchemy and a school full of people that performed that seemed clearly impossible.

Roy Mustang got off the seat of his desk and walked over to the two boys, his face impassive and indifferent. Catching on the message, both Al and Edward walked over to him, both knowing that the Colonel was absolutely serious about the current situation and secretive. The only person apart from the three of them in the office was Lt. Hawkeye and they all knew that she was to be trusted and she would never reveal anything without the consent of her superior and by superior it meant Roy.

Although they were alone in the room, the walls had ears too…

"Ed, this mission is undercover and very simple. You will protect a boy that is a possible target for a mass murderer that recently escaped their prison. He is attending a magic school that is hidden from the map and the view of many."

Ed shot a skeptical look at Mustang but Mustang ignored it completely.

"About the magic thing, although I cannot name the source of the power, it is very real but can be easily manipulated. There in that school, you will have to take the subjects that you are assigned and make sure that you do not reveal your identity at will. The age group that you will be in will be a year younger than you are. I believe you will easily fit in to that so you'll be placed in the third year." Ignoring Ed's "WHO THE HELL ARE YOU CALLING SO SMALL THAT CRUSHED BY A TICK", Mustang placed his hand behind his back. He looked at all and continued with a sigh. "Alphonse, I'm sorry but you will not be able to attend."

Ed looked at the Roy, his face contorted into disbelief and if Al had a face, it would be similar.

"What! Al comes with me everywhere!" Edward exclaimed, raising his arms in exaggeration before crossing the over his chest. His eyes dead set against the cool indifference of his superior.

"But Brother can't do anything without getting into trouble! Who will make sure he takes care of himself if I'm not there? What if he gets put in danger? I can't just leave him without backup." Al said, earning a glare from his brother.

The Flame Alchemist stood straight, his face remaining impassive, unfazed by the complaints of the boys. Hawkeye remained neutral throughout the tirades.

"What about the Philosopher's Stone?" Ed asked suddenly trying to keep his temper in check as they brought the supposed 'lead' in question.

"The wizards succeeded in making something called the 'Sorcerer's Stone.' It grant immortality and has the alchemic reaction of turning metal into gold by passing all the laws of equivalency." Mustang began, sucking all of Ed's attention.

"But it was created by wizarding means, not alchemic. The man who made the stone died recently after the stone was destroyed." Ed's face shifted into one of disappointment, eyes downcast. "but,"-he looked up hopefully- "it was created without the same ingredients and sacrifices. It could be possible for you to make one at the time that you are there. That is all I know about the stone." Mustang ended the conversation in a low keyed monotone.

Hearing that the wizards were able to make a stone like the Philosopher's gave Ed new hope but to hear that the only sample was destroyed took some of it away. But still, to make a stone like that without the same despicable sacrifice that the stone required was tempting, especially if it helped to get Al's body back. But to go to a school where they use magic was too incredible to believe. He was an alchemist, he wasn't supposed to believe in magic and the junk that parents told their children to have them behave or a witch will come down and eat them or something? It was possible that magic came from the other side of the gate but no one knew what was there. He knew he was going to regret going on the mission like that, especially if he couldn't bring Al along but it was his only hope to make a stone with their current situation.

"Brother, I think you should go."

Ed looked at his armored brother sadly. By the sound of Al's voice he knew that he could not convince his brother otherwise.

"It's decided then." Mustang's voice came in.

The Elrics looked at the man, annoyed. Ed scoffed in disbelief. He was supposed to go to some damn school and pass as a thirteen year old and he was expected to actually learn the stuff that they taught there. The only thing that might actually be worth the trouble would be if he could learn the basics components of the stone, and he would be able to create a stone, without the sacrifices. But he knew that it would be equivalent exchange. Something would be taken at the end but he would leave that on the back of his mind until later.

The worst part of it he had to protect a kid from a murderer. Hadn't he gotten his share with a mass murderer before?

"How long is it?"

His voice was reluctant and renounced.

"A year or longer."

"..."

"..."

"What! What am I supposed to do for one whole damn year there!" Ed yelled.

"Your mission," Came the calm Colonel's reply.

"Brother, you could research there and maybe you could create the stone without all the drawbacks." Al said, his voice understanding.

"If it makes you feel any better, you will be granted permission to enter their library and learn their weren't so dead set against it, you might actually learn something useful."

But Ed was not fooled. He could tell that his brother was deeply disappointed that he would not be able to help or join him in the mission. He was about to talk but Roy beat him to the punch.

"Fullmetal, go retrieve your belongings and come back. You will depart for your mission tonight."

"What! But I barley got here, you can't do that!" Ed yelled, his golden eyes wide and furious.

Everyone in the room suddenly became attentive. They all knew what happened when Ed was angered or pissed.

The youngest Elric once again came to the rescue.

"Let's go pack your things brother. The hotel is around the block, it won't take that long." said Al, trying to keep a big commotion from happening. True, he was beyond sad that he was going to be useless for an entire year and that he wouldn't be able to help his brother but if it could help his brother get his arm and leg back he couldn't say no.

As they both walked out the door, the other alchemist's voice came in.

"No Al, I need you to stay so we could talk about your arrangements with staying here." Mustang told the armor case. Killing intent could be felt in the room coming from the youngest alchemist in history.

"It's fine Ed." Al said before Ed could explode.

Edward threw his brother a slightly reproachful gaze and the walked the hallway muttering profanity about 'the damned bastard.'

As soon as his brother was out of view he steeped into the room again. He walked right in front of the desk that belonged to his superior.

He heard Roy sigh and pinch the bridge of his nose as he let go of the emotion that he bottling in. That was when Al noticed there was more to the story that met the eye.

"There's more isn't there?" he asked as Mustang nodded. Mustang opened his eyes and began explaining the situation to the youngest Elric.

"I sent him on the mission because of where it is located. The school is hidden from view, including alchemists. Unless they are taken in by a wizard it is impossible to place. The mission is just a front for sending your brother in for a long amount of time."

Mustang sighed, placing his arms in front of him.

"I want to make sure you are aware of the gravity of the situation and the danger your brother has been in. Both homunculi and a murderer are after your brother, one to kill him and others to force him to create a stone. I don't know why the homunculi want the stone but from we know they are powerful and as powerful as they are and the power of the stone it would be catastrophic, both to Fullmetal and the State. You've seen what large-scale powerful transmutation does to average men. To your luck, Edward might actually be powerful enough to pull something like that off, but we can't let it happen. There aren't many people in the state that could survive that type of alchemy. That's where we have an advantage."

"If we can keep your brother away long enough, then we could find out what they want it for and keep them from doing so."

Alphonse sat still through the whole talk. He shifted uneasily but nodded understandingly.

"So this whole magical world Ed is going to, is there really a chance he'd be able to create a stone? Or was it just to persuade him into leaving?"

"The lead I spoke to your brother about was not made up. I was told there was little chance to actually create one, but there was also a slim chance of surviving human transmutation. If there's a chance, Fullmetal will take it."

This seemed to cheer Alphonse back up. His hunched shoulders (of the armor) rightened up and he stood straighter, paying close attention to the man's words.

"But- will he be safe?" His voice was reduced to a squeak, full of worry and sadness.

"Like I said, that school is one of the most safest and protected places in the world and I doubt Scar or the Homunculi will be able to simply waltz in there." Mustang told him, his eyes narrowed. Al began to understand.

"So you're sending him there so he could be protected?" Al asked.

"Yes. But you can't tell your brother." Roy said.

Al noted how distressed and tired the alchemist looked at and how his eyes were tired. There were light bags under his eyes and his desk was a bit of a mess with all the paperwork.

"There's one more thing." Mustang whispered, then clearly wished he hadn't.

"What is it?" Al asked, clearly intrigued by the question. Hawkeye looked at the Colonel with mild surprise and once she recovered from it, she stood straight again and waited for any instructions that he might give.

"Nothing, I was just babbling." the Alchemist said suddenly, making it obvious that he was hiding something.

Before Alphonse could say anything Mustang continued, "There is a dorm that was prepared for your stay. You're is going to be next to Havoc's so you could just ask him for the directions." Mustang said, trying to ignore Alphonse's stare.

There was a sudden crack.

Surprising both Alphonse and Hawkeye, a man with blue robes and long white hair came into view. He wore half moon glasses and he had a great amount of wrinkles in his face that promised long age while his blue twinkling eyes betrayed it. His stature was tall and slim and his beard almost reached his torso. His nose was long and crooked as if it had been broken a few times. He looked at Mustang and at the armored boy.

"Did I come a tad early?"

A/N: Edit: August 12, 2012:

I am semi-rewriting this story, tweeking little part but the basis of the story remains the same. I think I was fourteen when I started writing this story, I am almost seventeen. I needed to get my ass into gear and I will hopefully finish this story before I'm eighteen. So there you go :DD
