My Little Homunculi: Alchemy Is Magic

It was a bright sunny day in Equestria. A perfect day. But the law of equivalent exchange states that you can't get something without giving something in return. As Twilight was about find out, her life would be completely flipped.

A strange pony was walking down a road. He had a tan coat with a yellow mane, and a metallic right foreleg, and left hind leg. He had awoken just a few minutes ago, and was unable to recall where he was, or why he was there. Or anything else for that matter.

Likewise a pink party pony was walking the exact opposite way on the same road. Suddenly she heard a metallic clinking, and hoofsteps. She hopped towards where the noise was coming from to find a pony with weird clothes on. He also seemed to be wearing armor, but the weird thing was that it was only on his right foreleg, and left hind leg.

Pinkie let out a gasp because she had never seen this pony before, and if she had never seen this pony before then he must be new, and if he was new then he must be lonely, and that made her sad, so she decided she would throw a party for him.

He noticed Pinkie, and started to ask her where he was, but it was too late. She was already gone. He let out a sigh, would he never find out where he was? At town Pinkie wasn't watching where she was going, so she ran into Twilight which sent all of her papers flying everywhere.

"Pinkie! What's wrong?" Twilight asked, worried about her friend's frenzied state. "Well I just saw a new pony, and if he's new, then he doesn't know anyone, and if he doesn't know anyone then he must be lonely, and if he's lonely, then that makes me sad, so I'm off to organize a party for him so he can meet some new friends." she said without taking a breath.

"Wait. A new pony? What did he look like?" Twilight asked. "He was tan with a yellow mane, and he was wearing these strange clothes. He was also kinda short, and he had armor on, though it was kinda weird since he only had it on two legs." Pinkie said.

"Hmm. That does sound weird. Well by Pinkie." Twilight said to empty air, because Pinkie had already left. She shrugged, and chalked it up to being Pinkie. As she used her magic to organize all her papers again she decided to go and meet this strange stallion Pinkie saw, and she walked off in the direction Pinkie had come from.

It didn't take long for her to find the pony Pinkie had described to her. A little ways away from town he was walking on the road head down, looking a little depressed. "Hi there!" she called out to him, making his head shoot up. She trotted over to him, and stuck out a hoof. "I'm Twilight Sparkle, you must be new here." she said. He took the hoofshake, and said, "My name's Edward Elric."
