A/N: And here it is, my second HPxFMA crossover. I'm not sure why I'm starting it now when I still haven't finished my other one, but I wanted to get the idea out before I forgot. Some helpful notes:

This will coincide with book three.
If you haven't finished the manga and you dislike spoilers, you should probably leave now.
Ed might be a little OOC, I'm not sure, if he is my excuse is that he's older and more mature at this point.

Ed breathed in the scents of the Royal Gardens. He had never been to Xing before now, and was glad he had taken Alphonse's advice. Ling certainly had it good here. He'd have to come back in a few years and bring Maes and Trisha along, and Winry of course.

"Ed! Long time no see!"

Ed turned around and grinned when he saw Ling. "Ling! Or should I call you 'Your Highness' or 'Your Majesty' instead?"

"You know, protocol is to bow when the Emperor addresses you," said Ling, still grinning like a loon.

"Ah, you know me, I never follow the rules. Besides, where's your official royal outfit? I bet your councilors would throw a fit if they saw their ruler dressed like 'the common rabble.'" It was true, Ling was dressed quite similarly to when they had first met, though the pants were black instead of white, and instead of his usual slippers... "Ling, are you actually wearing boots?"

He was, in fact, wearing black leather boots, almost identical to the ones Amestrian officers wore. "Apparently so, they're actually quite roomy. I think Greed left behind a liking for them." He pointed at his foot. "I never realized how pinchy those little slippers were. Look, I can actually wiggle my toes in these things!"

"...I can't see your toes, idiot prince."

"Hey! That's idiot emperor to you. And I can wiggle them, and it feels glorious. So how have you been? Al said you finally got married."

"Yep, two kids, too. Trisha is two and Maes is almost four." He pulled a picture out of his breast pocket. 'Holy shit, I'm turning into Hughes,' he thought.

Ling peered at the picture. "He looks just like you, how cute!" He looked at Ed again. "Speaking of which, you haven't changed at all. Literally, you still look sixteen, aren't you twenty-two?"

"Of course I'm twenty-two- wait a sec'," he took another look at Ling, "You still look sixteen too, what gives?"

It was that point that everything went white, and Ed heard an all too familiar voice. "Bet you weren't expecting to see me again, were you?"

"What do you want, Truth, I already destroyed my Gate. I don't have anything to do with you anymore," said Ed.

"Getting right to the point, I see. Good, because that Gate is what I'm here to talk about. Just so we're clear, I actually liked your idea of deconstructing your Gate in return for your brother. I think it showed wisdom too many Alchemists lack. However..."

"However, what? Get to the point."

"The deconstruction of a Gate is something that's not meant to happen, and it's caused... abnormalities."

"You're still not telling me why I should have anything to do with this."

"There are two dimensions, like two sides of an equation. The anomaly here has caused an anomaly on the other side. Someone survived who should have died, and it's wreaking havoc with the balance of life. In short, I have to reconstruct your Gate, and I can't do it for free, is that to the point enough?"

Ed thoughts immediately went to his brother. "No... Al... you're not going to..."

"Relax, I'm not taking your brother. Like I said, I liked your exchange, I thought it was clever. No, for the reconstruction of the Gate," Truth paused and appeared to be mentally calculating, "You and your friend cross to the other side."

"What! Hell no! I can't just leave my family!" He actually had a family to return to now, he wasn't going to do what Hohenheim did, dammit! His children were not going to grow up without a father, not like he and Al had.

"Oh, don't worry, you'll be able to get back. Now," Truth snapped his fingers and Ed felt all feeling leave his right arm. He looked down to see that it had been replaced by automail again, "Your arm for a helpful starting point."

"What the hell! A starting point to what!"

"Your return ticket, of course." Truth favored him with a toothy grin. "You want to get home? Fix the flow. Rectify the error. Remove the anomaly. Kill Harry Potter."

A/N: MUHAHAHAHAHAHAHAHAHAHAHAHA! Am I evil or what? I know this was a little short, but the other chapters will all be longer. I just wanted end on this particular note, since it's all dramatic and stuff. Will Ed be able to do it? I honestly don't know.

And yes, I know that Harry lived because of Lily's "power of love" spell, I'm just choosing to bend that for the sake of the plot. 'Cause let's face it, this is a fanfiction here. Also, I have an explanation for why Ed and Ling still look like teenagers despite being in their twenties. I promise you, I do have an explanation, I just haven't said it yet.
