Author notes- This is my first fanfic ever...so yeah, I'm going to do the first two chapters and see how it does in about a week or two, and based off that, I'll see what I do with this from there.
It was a dark day in Equestria, there were explosions and magic shots going off everywhere. Pegasus were having aerial battles all across the sky, and there were Earth Ponies fighting it out on the ground below. Rarity was resting a bit behind a pile of rubble with a dark grey stallion. His eyes were the color of the blood that trickled down his neck. He was panting, and just tossing a rock around. "One hell of battlefield out there, eh?" He said it as if it were any other normal day. Rarity smiled a bit, and rubbed some blood off her forehead. "Yeah, how do you think the others are holding up?" The stallion placed down the rock and cracked his neck a bit, "I'm sure they're fine. Rainbow Dash is supposed to alert us if anything major happens, so everything must be alright." Rarity hugged him, "I hope so." Suddenly they heard a rumble, and the barrier exploded, the stallion jumped back without realizing what was happening, and then Rarity was blasted back, as a pile of rubble fell on her. "Shit..." The pony flew down to the pile screaming, "RARITY!"
Ok wait a second, what's going on here? Well, lets go back about two months ago....
It was a beautiful spring day in Ponyville, the birds were singing, there were only a few clouds in the sky. Twilight Sparkle was in her home, reading a book as always. It was about how there could be other universes out there other than theirs, and it was assumed that if there were, the races were hostile. "Well what if they weren't..." Twilight mumbled, turning the page. Rainbow Dash was flying through the air enjoying herself. She had pulled off a few sonic rain-booms in her time, but not in a while. "Time to fix that" she said as she preformed one almost as easily as the one at the royal wedding. "HELL YEAH!" she whooped, flying back to her cloud home. Her mane was ruffled from flying at the incredible speeds she was doing, and she was about to go take a nap, but when she looked outside, she saw something she hadn't expected. "Are those.." a group of dark storm clouds was forming above Ponyville, "I didn't schedule a storm today!" she said. "When I find those pegasus..." Rarity was staring out her window as the storm clouds gathered outside. "Well that's odd, I didn't think there was going to be a storm today." Sweetie Belle was playing outside with Apple Bloom and Scootaloo. Rarity went outside to bring them in, "Come on in girls, a storm is going to be happening soon." They stopped, and Sweetie Belle complained "But Rarity-" "No buts, get in." Rarity objected, and went back in. The kids sighed and followed her in. Twilight heard thunder, and looked up from her book. "A storm? Well that can't be right." she pondered, "I'm gonna go check it out."
By this time, the clouds had blocked out the sun, and it was getting dark. Thunder was happening more frequently, and even some lightning was making an appearance. Twilight walked through town, other ponies were going inside, and closing their doors and windows. She got to the middle of town, and suddenly a large bolt of lightning struck down only a few meters from where Twilight was standing. Her mane stood on end, and it seemed the bolt was going on forever. She looked up, and she thought she saw something travel through the lightning and hit the ground where it was striking. As suddenly as it had appeared, it was gone. She stood there for a few moments, still shocked by what had happened. She then saw that the bolt had left a good sized crater. Now, the clouds were clearing up, and the ponies were coming outside to see what happened. One by one, Twilight's friends walked up to her side, and looked down into the crater. There at the bottom, lay a dark grey stallion, he had a midnight black mane and tail, and he was lying still, not moving. "Is he dead?" Pinkie asked. "I don't think so." Apple Jack said. It appeared this pony had no cutie mark, but as Twilight looked, she saw a mark in the shape of a lightning bolt appear on his flank. She saw him twitch, "Guys! He's alive, we have to get him to the hospital!" Twilight ran down into the crater and tried to move him. "AJ, Rainbow Dash, could you guys help me?" They nodded and went to help Twilight carry the mysterious lightning stallion into the hospital.
