A bit of a Disclaimer: I do not own Harry Potter or Fullmetal Alchemist. If I did, the Harry Potter movies would be a TV show, as for FMA, I'm happy with them the way they are.

(Also, this is kind of based off of Brothers in Arms, another FMA/HP crossover I love. Go check it out.)

Chapter One - The Gate

Harry Potter looked down at his work, it was a very complex transmutation circle. He had been working on the formula for months, with the help of Hermione. After training for so long in such a dangerous place and constantly moving, it was bound to leave scars. He got many from fights and skirmishes, but one. His left arm from the elbow down was chopped off, Hermione had used Dark Magic in order to give him a new one, much like Peter Pettigrew's. They worked and studied so many different types of magics, yes, including Dark Arts. Harry had become quite efficient using wandless magic, especially after his wand was snapped. But Hermione worked on alchemy, the formula that Harry was using was her idea, so they both worked on it, she got most of the credit though. It was her best work yet, too bad she'd never get to see it.

Hermione was killed in Malfoy manor by Bellatrix Lestrange. Ron was pissed. When the battle of Hogwarts started, Ron had attacked Bellatrix. Unfortunately, he too fell to her wand. Neville was able to take her out, getting revenge for his parents and friends, only to fall at the hands of her husband. Molly Weasley died hysterically attacking the Death Eater that killed Percy, Bill and Fleur died fighting side by side, Arthur Weasley died to Lucius Malfoy after saving Draco from being tortured by his father. Narcissa Malfoy killed her own husband, grabbed her son, and appeared away. Harry hoped they got out of England entirely and that they're save, he knew that Draco never wanted to be a Death Eater, maybe he'll get a better life. Tonks and Remus were dead and Teddy was in his care, but he knew he couldn't take care of him. With a heavy heart, he turned around and looked at McGonagall, the one who helped him set up this transmutation.

"I most likely won't survive this ritual, Professor." He said, with a tired and sad smile, "Take care of Teddy for me, will you? Yourself and the school, too, for that matter."

She nodded sadly, she knew that Harry wouldn't survive this, she could read the runes. "Goodbye, Harry Potter," she whispered, hugging him. He buried his head in the crook of her neck for a moment, forcing himself not to cry. He was basically about to kill himself, of course he was scared! Hell, he was terrified. But, he thought to himself, this must be done. With a sigh, he turned and walked onto the transmutation circle just as Voldemort walked in.

"I'm getting tired of this, Tom," He said, with an exasperated snarl. To those watching, he probably looked like he wanted to just get to the action already and end this. But on the inside, he really was tired, he looked the part too. "I've trained and prepared myself for this, let's end this the way we started it, together."

"With pleasure, Potter." Voldemort sneered, walking onto the transmutation circle, "I've been looking forward to finally killing you, once and for all."

Harry's eyes narrowed, "So have I," he smirked, "I've been waiting to test this circle out."

Voldemort looked down when Harry crouched and laid his hands on the smooth surface of the stone transmutation circle. The array lit up with a brilliant blue light, it was too late to turn back now.

"WHAT?! No! How?!" Voldemort shrieked, "Do you have any idea what you are doing, Potter?!"

"Of course I do, I'm getting rid of you." Harry said with a confident and calm air. "Even if it means sacrificing myself in the process. I will give everything I have to offer, my body, my mind, my soul, to have you irrevocably destroyed. But if I'm going to hell, then I'm gonna drag you down with me!"

The soft blue light changed to a violent, swirling vortex. Harry could feel himself being deconstructed, and welcomed it, there was no point in fighting. He looked over at Voldemort, the megalomaniac madman was desperately trying to find a way out, especially once he realized that magic was null and void in this vortex. Harry could hear someone call out his name, he panicked when he realized who it was, Luna!

"LUNA?! LUNA, IF YOU CAN HEAR ME, DON'T COME NEAR THE CIRCLE THIS MUST BE DONE! STAY BACK!!"

Just as he saw a pale hand with many bracelets come through the vortex, his vision went white, literally.

He was now standing in a white void, nothing to be seen but a completely blank canvas in all directions. Except, there was a huge stone gate looming over him from behind, on it was many intricate and complex runes and intersecting lines. All things he remembered from the diagrams in this Transfiguration, Defence, and Ancient Runes classes. He wanted to examine the door more, but then a voice caught his attention.

"Hello, Harry Potter."

He whipped around and came face to face with a rather strange entity. It was a silhouette of himself with no facial features, no hair, no clothes, and was in negative. The white on white creature sat like he had been awaiting his arrival.

"Um… Hello," Harry said with an awkward wave, "Who are you?"

"Ah, yes, you wouldn't recognise me in this form. Allow me to introduce myself anyways. I am the World, I am the Universe, I am God, I am Truth, I am All, I am One, I am even yourself, I could be life, but I can also be--" His form shifted into a tall cloaked figure, a man with deathly pale skin and pitch black hair, his eyes were a shining silver. "Death."

"Death…" Harry breathed. "So, I really am dead, then?"

"Yes."

"What about Luna?!" Harry exclaimed, not out of anger, but out of fear. "She followed me into the transmutation circle after it activated. Is she dead, too? Please tell me she isn't!"

Death shook his head, "No, Harry, she is not dead, however she cannot return to the world you came from, you can only move on. Her fate rests with you."

"What do you mean?"

"I mean what I said, whatever happens to you, she gets the same fate." Death said, "I shall give you two options, move on to the next life and she will die with you, or I shall send you to a new world, but for a price."

Harry seemed skeptical, "No offence but, why are you giving me a chance in the first place?"

Death chuckled, "Because, you found, collected, and own all of my Deathly Hallows, surely you know what that means?"

"I'm… your master?" Harry said, recalling the story about the three brothers.

"Not quite," Death said, with a shake of his head. "You Wizards always have to make every achievement seem as if it's some big grandeur! No, it simply means that you are favored by me, which allows me to give you a choice in the first place. Under normal circumstances, I would have just thrown your soul, and that little girl's, back into the human reincarnation cycle, but since you collected my Deathly Hallows, I get to have a bit of fun."

Harry weighed his options. He could pass on, see his family, his friends, but Luna would have to die too. Or they both could go to some unknown world for a 'price'.

"The second option, this 'price' you mentioned, what is it?"

"Observant as always, Harry," Death said, "This price is a toll. Payment for passing through my gate to the next world and the knowledge that comes with it."

"And if I choose this option, that price will be…?" Harry prompted.

"I shall be nice and allow you to decide. Just know that once you come to a decision, you cannot go back on it. However, if we meet again before your time, I won't be so lenient with you."

Harry contemplated his warning, what did he mean by 'before your time'? As in, before you're supposed to die? Also, what was he willing to give up? Not his magic, he needed that, so did Luna. An Arm or a Leg? No, he would much rather not have to go through the whole shebang with his left arm again, and definitely didn't want Luna to have to deal with that. Besides, what if there weren't any humans around when they got there? Losing a limb wouldn't be practical. Organs? No, those were important. His sight? He was already practically blind without his glasses, so it wouldn't be much of a loss. But then again, he wouldn't be able to tell where Luna was, and neither would she for that matter. Then he got an idea.

"What about Age?" Harry asked. "You could take off about a decade of our ages, revert us back to children. It would frustrating enough for us, and I'm sure you'd love to see us struggle."

Death chuckled darkly, "Yes, that would be fitting. So, you would like for me to send you and your friend to another world for the price of a decade of age off your bodies?"

Harry nodded.

"Very well," Death waved his hand and the gate behind him opened, thousands of tiny arms reached out and grabbed him, dragging him inside. As the doors closed, he heard Death say, in his silhouette form might I add.

"Good luck, Mr. Wizard. And say hello to Edward for me!~"
