CHAPTER ONE

The Beginning of a Dream

. - . - . - . - . - . - . - . - . - . - . - . - . - . -

Edward looked out the window, sighing tiredly. His golden eyes looked far away in the distance, at the trees speeding up past them. "I don't get it," he finally spoke.

The suit of armor next to him that he liked to call brother looked at him. "What do you mean?" he asked while handing the blonde a piece of bread from his bag.

"I don't understand that Lieutenant Colonel Mustang. Forcing us to get this train instead of the other one..." after taking a bite of his food, he focused again in the window. "I wonder what kind of person he is."

Ed blinked twice, when his younger brother suddenly waved his hand. He noticed then that it was directed to something behind him. He turned his head to see, just in time to see a little girl quickly hiding herself in her seat.

Alphonse lowered his head. "Brother," he muttered. "Am I scary?"

"That's not-" the elder brother wanted to say.

"Hey, there's a weird person!"

"Marin, no. Be quiet."

At every word the kid spoke, Al looked gloomier. Edward was feeling a little irritated at it, and thought about telling the child something when they heard steps coming their way and stopping right next to their seats.

"Excuse me," a soft, dreamy voice said. "Could I sit here?"

They looked up almost instantly. Messy, dirty blonde hair almost covered the girl standing in front of them, who looked close to their age. Her silvery eyes were strange, though; it seemed like they were staring at them, but at the same time they weren't.

Edward looked at her... and looked. An eyebrow raised questionably.

"There are plenty of empty seats, you know."

"Brother," Alphonse whispered to him. "That was rude."

Not that he cared anyway. The girl didn't seem to mind, either.

"Yes, but as you say, these are empty seats," she smiled at them. "I don't like sitting alone," without previous advice, she sat next to the younger brother. "Thank you."

Ed was about to protest, but Al looked at him and slowly shook his head. He huffed, crossing his arms and looking out the window. The girl didn't erase the sweet smile from her face, which seemed to annoy him even more.

"I apologize for my brother, miss," the armor directed to her, politely. "I'm Alphonse Elric, and he is Edward. Nice to meet-"

"I see you are polite indeed, I like it but it's not necessary," she cut him off. "You know, I always wondered why people always say that it's nice to meet someone, if they honestly don't know if they are good or bad people. I mean, they just meet them, how can they tell?"

If Alphonse had eyelids, he surely would have blinked. He had thought that the young woman in front of him was weird when he saw her, but now that she talked he confirmed it. Honestly, he couldn't tell if that was a good or bad thing.

"I'm Luna Lovegood," she introduced herself, even if anyone asked.

"Oh," even if he was in a lost of what words to say, he forced himself to speak, to get rid of possibility of an uncomfortable silence. "That's a nice name."

"I know," she said. "So, what brings you two to Central?"

Before Al could speak, Edward did so. "Long story," he mumbled.

"Well, actually mine is kinda long as well. You see..." again, none of them asked, but she spoke nonetheless. "I was about to take a train from Rush Valley, where a friend of mine lived, to my home in central when accidentally took the wrong one and ended up in East City. I suspect the nargles changed my ticket with another one's."

"What's a nurgle?" Alphonse asked.

"It's nargle, be careful. They don't like their name being mispronounced," she told them, seriously. "They are mischievous creatures. They have fun by stealing possessions, sometimes exchanging them between people."

The Elric brothers glanced at each other, without saying a word.

"As I was saying, I had to take this one to return home instead. Then, I was surprised to see a living suit of armor in a place filled with muggles like this accompanied with a boy with automail limbs, so I asked myself; how can they be so careless? Curiosity took over me and-"

That was when Luna noticed them both staring directly at her, looking both surprised, confused and nervous.

"How do you know I'm not a human wearing an armor?" Alphonse asked.

She raised an eyebrow, still smiling. "Am I supposed not to?"

"Wait a minute, before that..." Ed narrowed his eyes in suspicion. "What the hell is a muggle?"

Her smile faded, as she realized what she had just said. "They are muggles?" she wondered. "Then, how is that this Alphonse...?"

The brothers after a couple of seconds let go, dismissing everything as just madness of the girl.

Edward then sighed. "So, this girl sat with us because of Alphonse's looks? We are not that..." he looked around, noticing that every passenger was staring at them warily, "... strange..."

He turned his head to Al for a second before lowering his gaze, in shame. The memories of what they had gone through a month ago filled his mind. In his head, flashed the blood from his now-gone leg, his brother disappearing, when he draw the rune of blood in the armor. And the thing they created, which was supposed to be their late mother. Again and again.

Alphonse took no time to notice what was going through his head. Then, he worried a little when he noticed Edward's hand going straight to his head, closing his eyes in pain for a moment.

"Brother?" he asked, softly.

"By the way... I..." he looked straight ahead, looking somewhat lost. Like he had forgotten what he was about to say. He let out a long sight. "Sorry. My head's kinda fuzzy..."

"Are you alright?" the metal boy asked in concern.

"I knew it," in confusion, both looked at Luna. "This place is filled with wrackspurts."

"With what?" Ed's half-lidded eyes narrowed at her.

"Wrackspurts, I thought I heard one around. They are invisible and float through your heads, making your brain all fuzzy," she explained. "They are attracted by negative thoughts..."

She stopped her speech for a second, smiling up ahead. The boys looked at the direction she was looking at, noticing the kid from before grinning while waving her hand at Al. They both smiled widely as well.

"Hey, Al, look. She likes you," Ed turned to the child. "Right?"

"Yeah!" she nodded, happily. Her wide eyes then fell on Edward's automail, who blinked twice before grinning, when he realized what was she looking at.

"Isn't it cool?" in response, she nodded again.

"Come on, Marin. Don't bother them," the mother told her daughter.

The woman then turned to the others, who smiled politely at her. Even when the women sat again, Luna kept the smile on her face.

"So, naturally, the only way to dispel them is by positive thinking," she whispered, finishing her explanation.

Only then, Edward realized he was feeling good again. That girl, maybe, wasn't as insane as he initially thought she was. He dismissed any thought at the moment as he lied down in his seat and told his brother and the strange blonde that he was going to take a nap.

But his nap was shortly interrupted when a man ran to them and stopped in his tracks. "Yes! There's one!" the man exclaimed. "He's really small!"

As Alphonse predicted, in a split of second his brother was up. Angrily waving his fists around in a hysterical tantrum. "Who did you call a shorty that can only be seen through a magnifier?!" he yelled at the top of his lungs.

Luna raised an eyebrow, turning to the armored guy. "Who did?" she asked.

"Nobody," he sighed. "Brother is overreacting... as always."

The girl giggled a little, before glancing at the man, finding him somewhat familiar. She tried to remember him, but nope. Nothing came into her mind.

The man retreated a little at the Elric's outburst, when he seemed to notice something. In a flash, he had taken his gun off and was pointing at a passenger, who also was pointing at him with one of his. The man then tensed, when he realized that the one behind him had the same weapon, ready to blow his head off. Just when he was about to put the gun down, he was knocked unconscious from behind.

In the end, the only trained soldier was tied up, leaving all the other people on their own.

There was a collective gasp, as the thugs told everyone to raise their hands. Having no more option, everyone complied.

Wait, no everyone. Guess who wasn't doing it? If you said Luna, you were right, of course. She just stood there, staring at them with a dreamy expression, the one she always had on.

"Hey, missy," one of them said. "Weren't you listening to us?"

"Yes, I was," vaguely, she answered.

"This train is hijacked by us, right now!"

"I know that already, thank you."

Edward blinked twice, turning to his brother. "What is she supposed to be doing?" he whispered to him.

"I have no idea," that was his honest answer.

Meanwhile, the man seemed to get a little annoyed, so he walked a little closer to her, placing his gun in her forehead. Everyone, but her, flinched.

"Why aren't you doing as I say?" he asked.

"Because I don't see why," Luna answered, unfazed even if she was in risk of having her head blown out. "You may kill me even if I do as you say, so what's the deal?"

The thug couldn't get it, how was she so unfazed to death? She obviously could die, she was human after all. There was something on it that made him uneasy.

Then he realized that couldn't be the exactly thing that he didn't like. The shine of her eyes, one of motivation, reminded her of something... of someone. Maybe from when he was in the military, before rebelling...

Stop it right there. Oh, that was it.

"Oh, now I got it," he spoke after a while. "You're that bastard's daughter."

"His niece, actually," she corrected. "Old friend of his, I can see," then, a smile drew in Luna's features. "Okay, then. I will hold up my hands for you."

In a swift motion, she raised her hands, and her left foot. She kicked him in his hand, making him drop the weapon. He wanted to retrieve it, but she hit the man's stomach, leaving him in the floor.

She innocently gazed at his other two partners.

"You-!" one of them said, before he abruptly stopped.

Ed's knee in the face shut him off, as Al's punch knocked his friend out of cold. The brothers grinned at the same time - or so Luna supposed about Alphonse. Little after that, the people in the train started whispering about it, with worried faces.

"Hey, what are you two going to do now?" one of the passengers asked, in worry. "What if the other members come to get revenge?"

"If you hadn't resisted, maybe we could've gotten to Central City, safely..."

"Yes..."

"That's right..."

Luna lowered her head a little bit, troubled over the idea of spreading panic on people she didn't know. Among them people with family. She even frightened little kids!

Alphonse and Edward seemed to be in a similar situation, looking at each other once again. Luna opted to not think about it anymore, and walked over the fallen soldier. Helping him was a little more useful, she through.

"Thank you," he said to her, once she helped him to sit.

"Uh, it's nothing really," she replied, after a few tries of undoing the knots, in vain obviously. That's when she noticed something, and looked at him straight at the face. "Wait a second, could you be Mr. Farman?"

"Yes," he looked at her, still confused.

"You work with my uncle," she grinned from ear to ear.

His eyes fell on her, and stared for a long time before opening. He smiled politely. "Luna," he recognized her. "You've grown."

"Have I? Thank god," she sighed. "I was worried that I had been seen by a pink eyed owl without noticing..."

Farman had no idea of what she was talking about, and choose to keep that to himself. Probably, that was the wisest option that he could have taken.

They both heard a slam and a shot, almost in the same second. Their heads snapped towards the sound, just to see Al's feet right in a thug's back, keeping him down, and Ed holding a gun, probably stolen from the same man.

Same blonde turned around to talk to the little girl from before, smiling at her and bending over.

"Sorry," he told her. "We'll do something about it."

With still watered eyes, the girl clutched even more in her mother and gave him a slight nod.

"Luna," Farman turned to the teen behind him. "We should hurry."

"Right, right," she tried to untie him once more, but it was useless. Discretely, she pointed her hand at the ropes - or the stick of wood under her sleeve, more likely. "Libero."

"Huh? Did you say something."

"Oh, nothing. You know, speaking nonsense to oneself keeps mischief fairies away. I'm pretty sure I saw one around," even Luna believed that mischief fairies didn't exist, but it kept Farman silent and confused. That was good enough, "Oh, look. I did it."

The ropes fell over at the same time that the Elric brothers walked closer to them. Al stretched a hand to him, and he thankfully took it.

"I'm ashamed. I'm the one supposed to do something about this," he sighed. "Who are you two?"

"Oh. We are just plain alchemists," Edward replied.

Luna hummed to herself. That explained a little about how a living armor was walking around a place that muggle-infested. But she still couldn't get what made Alphonse to have to live like that. Let me rephrase that, Luna deep inside knew what was going on. The other thing was that she didn't want to believe it.

"A military personnel?" Ed's voice brought her back to reality. He was still talking to Farman. "You don't look like one."

"Wait," Luna suddenly said. "I wanted to ask you before; what's the military doing here?"

Whispering, he told them all the truth behind the mission. About General Hakuro, the State Alchemist that had rebelled against the military, who is the mastermind behind all of this... Everything.

The elder alchemist didn't like they way of getting civilians involved, letting everyone know by knitting his eyebrows together. "Al, I'll go from above," he told his brother, before nodding him to the soldier. "You go from the bottom with this person."

"What...?" at first, the metal boy wavered, but then nodded. "Okay."

"I'm going with you," Luna decided, looking straight at Al.

"..." none of them said anything, just looked.

"What? If I went from above, I would fall. I preffer going from the bottom."

"..."

Luna was wise. Wise indeed... When the door opened, she decided to stand right behind Al for protection. She looked as the man with the machine gun opened his eyes widely.

"Ah, you shouldn't fire-!" the armor tried to warn.

He didn't listen, he just began to shoot until he hit his own leg. Alphonse shook his head, he was trying to tell him that the bullets were going to ricochet.

"What's wrong?!" another one appeared and pointed his own gun at the boy, in fright.

"Ah, you shouldn't fire-!"

"..." more shoots were heard. "Aaargh!"

"Ugh," Alphonse groaned in frustration.

"That's what they call a deja-vu, I think," Luna commented, while Alphonse held his head down, palm in his face. She then realized something. "You keep going, I'll help the passengers."

Alphonse nodded, and Luna ran towards the first door. She closed it behind her back, as the first men pointed the gun at her. The Lovegood girl grinned, as she took her wand out of her sleeve.

"What's that?" he asked, in confusion.

"A wand," she answered as if it was the most common thing in the world. "It's my big secret, you know. Do you have any idea of why I'm telling you this?"

He let out a laugh, thinking that she was just nuts. "Because you will kill me?"

"Of course not, silly," she laughed his comment off. "I was covering my magic before because I'm not sure if the False Memory Charm affects a living armor... But with plain muggles will do."

His eyebrows frowned.

"Bombarda," she whispered.

Luna kept advancing through the rooms, kicking the men out the compartiments, leaving them unconscious in the hallway. After doing that, she would always remember to place a false memory in the muggle's head; probably making them think that she just performed alchemy or something of the same kind.

That was when Edward's voice suddenly echoed in all the train.

"Can you hear me, everyone from the criminal group?"

"What the-?" the man in front of her asked, in the middle of their 'fight'.

"How you dare to threaten everyone! Release the hostages!"

There was a brief pause. Luna supposed that Edward was having a word with someone, and they just couldn't heard it. Little after, he began to talk again.

"Oh? Looks like you are full of determination! Then... Hostages! Please take cover!"

The girl quickly looked at the man in front of him. "Well, you all the last one, aren't you?" she told him. She realized vaguely that she had let the door open. "Want to get out nicely?"

"Huh?!"

"Alright," she raised her wand. "Flipendo!" the man fell back to the corridor. "Obliviate!" Then she closed the door and remembered: "Blimey, I didn't change the memories... Oh, well."

Right after changing the hostage's memories, she heard something. Like water rushing out around the whole train.

Luna was grateful she stayed inside...

As soon as the train came to a stop, the young witch walked out the train - after, of course, almost slipping twice in the wet floor as the dumb, young witch she was. Once outside, she found all the criminals tied up, defeated. Half of them, maybe a little less, were taken down by her. It made her feel a little more proud of herself.

There also were the Elric brothers and the rest of the military, looking in shock at something. That was when she noticed that the infamous Lieutenant Colonel Mustang was also there, in front of a combusted somebody. She guessed that he was the responsible of it.

"Lieutenant Colonel! You put us on this train knowing about this, didn't you?!" Ed shouted, angrily.

"We didn't know everything," he admitted. "By the way, I have good news. The General has heard of your accomplishment. And he will be giving the two of you special permission to take the State Alchemist test."

Edward then went in shock after realizing that in reality, children couldn't take the exam in any way. Luna giggled. "Typical Mustang."

After telling him that it was his choose to take or not the exam - and receiving a no-so-gentle answer from the kid - the Flame Alchemist walked away. Luna was about to do the same thing, when she almost lost her balance.

"Luna~" a male voice said, as strong arms hugged her tightly.

Edward and Alphonse broke they serious facade, as they saw it. The girl smiled slightly, hugging the man back. When they broke, she spoke.

"Were you on the same train than me, Uncle Maes?"

"Funny long story. I'll tell it when we reach home."

The brothers just blinked at the revelation. "Uncle?" they said in unison.

"Yes," Hughes smiled to the boys. "Well, it was nice to met you guys. I guess we'll see you later."

"Same thing," Luna smiled. "Until then."

"Luna... Luna..."

The eleven year old girl opened her tired eyes and looked around the place. She realized then that she had fallen asleep on her father's lap, while they were travelling. Grinning widely, she stretched up and positioned herself in a sitting position.

"What did you wake me for, Daddy?" she asked him.

"We are almost there," he stood up. "Let's go, honey."

Luna nodded her head, looking out the window before standing up, confirming that her dad was right. Once they got out of it, her eyes widened in delight at the amount of people and shops there in Diagon Alley.

"You will make a excellent witch, Luna," proudly, his father bend down and kissed the top of her head.

Not that she wanted her parent to know, but she was already a fine witch. The thought of it made her slightly less excited about getting to Hogwarts. Still, she smiled.

"I won't let you down."

Deep down, however, she couldn't wait to go to bed once again.

AUTHOR'S NOTE

. - . - . - . - . - . - . - . - . - . - . - . - . - . -

It has been a while since I posted a fic - not that I posted that much anyway.

This is something that once crossed my mind once, and wrote it down. I know it can be confusing, but I will expand on it later in this story. This story will based in the 2003 storyline at first, but then I'll shift to the 2009. That was because I couldn't chose only one version of this powerful anime.

Romance will take a little to develop, since I strongly believe that relationships of this kind aren't bonded in a matter of a couple of days.

Luna is a hard character for me to keep. I'll still do my best. The 'libero' spell, the pink eyed owl and the mischief fairies were things I made up, trying to fit Luna in the fic. Pay no mind, please.

I don't want to bore you anymore. I just want thank you for reading this, I will update as soon as I can. Sorry if my English isn't good enough, Spanish is my first language. I'll try harder to improve that.

See you later!
