Alchemy: the science of understanding the structure of matter, breaking it down, then reconstructing it as something else. It can even make gold from lead. But alchemy is a science, so it must follow the natural laws: to create, something of equal value must be lost. This is the principle of equivalent exchange.

A small house in the town of Resembool

"Ed, do you think that we should be doing this. I mean all the books say that this is forbidden." A little blonde boy asked the only other occupant in the room.

Two boys were currently in what appeared to be a basement. The room was outlined in several suits of armor. But at the time, that was not the most interesting feature of the room. In the center of the basement, there was a large circle filled with strange markings made out of chalk, and several ingredients piled in the center.

"Al, the only reason they say that it's forbidden is because no one has ever done it right before." The taller of the two said condescendingly.

"All right, all ingredients are here. Water, 35 liters. Carbon, 20kg. Ammonia, 4 liters. Lime, 1.5kg. Phosperus, 800g. Salt, 250 g. Niter, 100g. Sulphur, 80g. Fluorine, 7.5g. Iron, 5g. Silicon 3g. And fifteen other elements. The ingredients for an adult human body." Edward Elric turned to his little brother. "Are you ready to bring mom back?" he asked.

"If you're sure." He handed his brother the knife that they brought with them. He was already holding his own.

They both held their hands over the pile of ingredients, knives inside the palms of their hands.

"The one ingredient that science has never been able to reproduce. The soul." And with those words, they sliced their hands and let the blood drip into the pile.

They both then walked over to the outside of the circle, got on their knees, and placed their hands on the outside of the chalk.

Outside, you could hear a large storm going on. Lightning was striking, thunder was rumbling, and rain was pounding the side of the house.

"Ready Al?" Ed asked his brother.

"Ready brother." Al replied.

"And… Start!"

All of a sudden, the chalk lines started to glow gold, and lightning was striking the pile in the center. The ingredients were mixing and swirling, and forming into something that was starting to look humanoid. Then the golden light grew out from the chalk line, and swirled around the center of the circle.

Outside the golden storm, Ed and Al were grinning like maniacs.

"Finally, she's coming back!" Was the only thought running through Edwards mind.

Suddenly, the gold light turned purple, and the blue lightning turned red. The smiles were no longer on the boy's faces.

The next few moments were a blur for Edward. All that he remembered was seeing a large gate in a pure white expanse, the pain of feeling his leg disintegrating, his brother disintegrating, seeing a pile of what should have been his mother in the center of the circle, binding his brothers soul to a suit of armor, the pain of knowing everything for a few moments, and a pure black figure with a creepy voice saying "Try this again and not only will your brother be lost, but you as well." And then, nothing.

Earth 16, December 13th, 2007, New Orleans

There was a certain appeal for the December air in New Orleans. The normally hot and humid environment was cold and it made for a lot of fun in the snow for the children. It also helped the scenery for a nice walk. This is where we find a past member of the justice society, the precursor for the justice league, Kent Nelson.

After he retired from being Dr. Fate, he would usually take these long walks that sometimes lasted for days, weeks, or even months. New Orleans was his favorite place. He liked to go to the fortune telling tents, and see if there were any people who could be good candidates for the Helmet of Fate.

It was on this particular evening that he would get the first bit of action since the etrogan incident of 1997. He was walking towards another tent, the 5th of the day, then he sensed a powerful energy surge, maybe a block over.

He started to run towards said surge, moving at a pace that betrayed his age. The scene that the retired sorcerer came upon in the ally that the surge came from was, to say the least, horrifying. In the alley was a blonde kid, with a red shirt. He was missing his right arm and left leg. Blood was everywhere.

Kent knew he had to help this boy, not just because he was bleeding out, but because now that he was at the source of the surge of energy, he could tell that it was a type of trans-dimensional portal. That meant that this kid was not of this reality, and as the house keeper for the tower of fate, it was his job to help this boy return home.

The first thing he did was use his magic to cauterize the wounds that he had, so he would stop bleeding. Then he did some stasis magic to keep him in his current state until he could transport him to the tower. He then levitated the boy, and started his trek back home.

2 days later Inside the Tower of Fate

Edward had some strange wake ups in his life. When he trained with his brother for one year, they were both woken up in many different ways. Once was by teacher transmuting their beds into a slide, and having the ending point slam them into each other. Another was by filling the room up with fire ants. Another was by dumping hot coffee into their faces. Another was by…. You get the point. But this had to be his strangest wake up yet. When he woke up, he could feel the ghost pain in his leg and arm. His vision was fuzzy. And he was sure that his room wasn't this fancy. Four post bed, sheets made of linen, Victorian aged wardrobe, etc.

Then he noticed he was alone. Where was Al? Where were his limbs? Where was he?

As if someone heard his questions, the door opened to an elderly man, wearing a 3 piece suit. He held an air of authority, but also looked like he didn't have a care in the world. It was very soothing to Edward.

The elderly man then held up his hand that had a glass of water in it. Edward then realized that he was extremely thirsty.

He reached for the glass automatically with his right arm, then realized that it was not there.

"Forgot about the lost limb?" The elderly man asked.

Edward got mad and made a swipe for the glass with his left, but the old man brought the glass back before he could reach it.

"You also forgot to say please, and thank you." He reprimanded.

Ed looked down. He then reluctantly asked for the glass. When handed the water, Ed took small sips. When finished, the strange old man took the glass from him, then took a chair that was in the corner of the room and sat down, waiting to see if the boy would talk.

After a minute, Edward looked to his apparent savior and asked "Where am I?"

Kent took a deep breath and told him "I don't think I can tell you where you are without telling you that you're not in a place you will recognize first. My name is Kent Nelson. When I found you, you were in an alley bleeding to death. I took you home and helped you heal."

"If you don't mind my asking, and not to sound ungrateful, but why was I in an alley, and why did you help me?" The eldest Elric didn't understand any of this. "How did I end up in an alley? What does he mean I won't recognize the name of this place?"

It seemed the man could read him like a book "I should explain further. I am a sorcerer of the planet earth. When I was taking a stroll through my favorite place, I felt a surge of energy. When I got to the origin of said surge, I found you. I then realized that the surge of energy had to have been a portal from another plane of existence, meaning that you aren't in your own reality. That is what I mean by you won't know the name of this place."

He paused to make sure that the blonde was keeping up. After he deemed he was, he kept going. "But you are in the tower of fate, the central point of magic, and cosmic power of this dimension. As the keeper of this place, it is my duty to make sure that you get back home. So, what's your name, and the name of your country?"

Edward was skeptical, but told him. "My name is Edward Elric. I come from the country of Amestris."

A look of recognition appeared on Kent's face. "Oh! Then that means you come from the dimension that has all those alchemists, right?"

Edward nodded his head. "Does that mean you can take me back to where I come from?" He asked, hope filling his eyes.

"Yeah, it'll just take me a few moments." Kent replied.

"That's…." Edward was about to say great, but then remembered the words of that strange black creature.

"Try this again and not only will your brother be lost, but you as well."

He snapped back to reality, and looked up to see Kent looking at him expectantly.

"I can't go back. I think if I try, then not only will the person who sent me here take my soul, but my brothers as well."

Kent looked surprised. "What would you like to do, then?"

Edward looked up at Kent, and thought. "I guess try to live a life here. Maybe try and find a way home that won't upset the laws of equivalent exchange."

"The laws of equivalent exchange? Does that mean that you are an alchemist?" Kent asked, intrigued. He hadn't seen an actual alchemist in decades.

Edward at first had a look of pride on his face, but then it fell as he said "Yes, but without any books on alchemy, I can only go by what I know now. And without automail limbs, I can't even walk right."

Kent started laughing.

"What's so funny!?" Edward asked angrily. This man was laughing at his misfortunes.

"Oh, I'm not laughing at you, calm down kiddo. I'm just amused how you think that the books of alchemy are only held in your dimension. In my retirement from being a superhero, I like to read from the vast library of this tower, and let me tell you, this tower has books from every reality, including books on alchemy and the art of making automail."

At this, Edward felt that glimmer of hope that he was starting to get used to, and then it turned to suspicion. "I don't understand one thing though. Why would you help me?"

Then Kent got a serious expression on his face. "Don't get me wrong. I still expect something from you in return."

"What's that?"

Kent smiled. "What do you think about helping people?"

End chapter

I got the idea for this story after wondering what character from anime's would be perfect for the Young Justice team. I just wanted to read a good crossover fic. Then I thought of alchemy. Great power for this world. And great concept with equivalent exchange. But when I went to go read some FMA/YJ fics, I found out that there was almost none.

Then I talk with my brother, and he talked me into writing my own fic. I did steal a concept from Black Phoenix Risen's 'Shinobi Rising' in that the person that finds the dimension traveler and introduces them to the justice league is Kent Nelson.

To me, it just makes sense. How else is Ed supposed to get information that he needed to become a great alchemist. He did study in anime for months before taking the state alchemist certification exam.

I am contemplating the idea of having a homunculus join the story, but that is just an idea.

This is not my first story attempt, but it will be the one that I will put my all into.

In the meantime, I'm justchillin,killin.
