Discord is back and he wants revenge in the Mane Six. But, he seeks help. He changes Luna back into Nightmare Moon. They have Princess Celestia trapped and she's defenseless. Will Twilight and her friends stop them before it's too late?
In Equestria the weather had been acting strange lately. It had been nothing but storm clouds all day. It wasn't any ordinary storm though. The storm clouds were really low and puffy, the lightning would only strike if anypony went outside, the rain would be normal at times, but sometimes it would be so hard that it would pierce through roofs, and sometimes the clouds would get so low that it would make a really thick fog. The fog would be so thick that it feels like its choking you. Everypony had been told to stay inside and let the pegasi handle it. But, even the pegasi are having trouble. They tried to blow the clouds away, but some of the clouds would get into their throats. Rainbow Dash would try to at least punch a hole in the clouds, but she would get all tangled up. It took them weeks to get her out, let alone a month to find her. The pegasi asked the unicorns to help. The unicorns' magic wasn't powerful enough to even make a piece of the storm go away. Twilight tried to use a disappearing spell, but the lightning struck her before she could do anything. Even Applejack tried to pull away the clouds with her rope, but mysteriously the cloud flung her into an apple stand. Everypony gave up after a while. Although Princess Celestia believes it's something more than just a regular storm. She tries to bring a letter to Twilight, but the storm interferes with her magic. She just hopes Twilight is just doing something to help.
*Twilight's house*
Twilight and her friends were having a sleepover before the storm even happened. They thought it would blow over. But, the storm has been going on for 3 weeks now. It also cut off the electricity in her house. Rainbow groaned, "This has been going on for days. I can't stay cooped up here." Rarity explained, "Please stop complaining Rainbow Dash. The Mayor said that we have to stay indoors." Rainbow sighed loudly. Fluttershy was trying to get Angel to calm down. But, the rabbit kept on throwing fits. Applejack just fell asleep; her head was lying down on Twilight's nightstand. Pinkie Pie was just jumping around. For some odd reason she was having fun. Twilight was looking for a spell to turn on the lights. When she found one her horn glowed a blinding light, a few sparks went around the lights and he flickered on. Everyone sighed in relief; well except for Applejack. Twilight sighed, "Now all I have to do is find a spell to get rid of the storm." Fluttershy got in front of her and asked, "Please don't get mad Twilight…but…uh…Don't you think you've done enough?" Twilight yelled, "Are you serious!" Fluttershy screamed and hid under her table. Pinkie consoled, "It's alright Fluttershy. Twilight isn't mad at you. Are you?" Twilight shook her head, "I'm not it's just I'm…" It seems like Applejack hear her. She picked up her head and asked, "You're what, sugar cube?"
Twilight continued, "I guess I'm scared. I don't know what's going on. I mean I haven't slept in days!" Rarity pointed out, "That would explain why your eyes are puffy." They all looked at her. She continued, "Well they are. If only the spa was open." Applejack agreed, "If only anything was open. I wonder what's causin' this ruckus. Oh sorry Pinkie, I mean fracus." Pinkie shook her head, "No. This time it's a ruckus." Applejack rolled her eyes and smiled. Twilight gasped, "You don't think it could be…" Everyone looked at each other. Fluttershy said, "Didn't we get rid of him already. We would get signs of his return." Twilight put a force field around them. Rainbow asked, "What're you doing?" Twilight explained, "If he is back, we need to protect ourselves from the lightning. I think we need to go to the Canterlot garden." Pinkie pie asked, "Won't that take like forever?" Twilight sighed, "Well we better get moving." They shared looks and followed Twilight outside.
*Outside*
When they took one step out a lightning bolt immediately hit the field. They jumped, but noticed that they were unharmed. Twilight motioned them to move forward. The lightning bolt strikes kept coming; some were stronger than others. But, they pressed forward. It took them an hour just to make it to the train station. Twilight looked back just to make sure everyone was alright. Applejack complained, "Twi, can we stop? I'm plum tuckered out." She shouted, "No! We have to keep going. Plus if we follow the tracks, it would only take two hours." Everypony groaned. They were worried about their friend. They thought that she was worried for nothing. Twilight pressed on forward and the others lazily followed.
*Two Hours later*
They finally made it to Canterlot entrance. Even Twilight had to admit it, she was tired. But, it could be too late if they stop moving. Twilight huffed, "C'mon guys we can't stop moving!" Everyone was lying on ground breathing hard. Rainbow pleaded, "Please Twilight can we stop moving. We've been walking for hours. Can't you just teleport us there?" Twilight shook her head and kept moving.
They sighed and followed their possibly crazy friend. A few hours later they reached the Canterlot Garden. Twilight looked around for his statue then found. But, she got upset knowing that his statue remained in place. Rarity groaned, "Are you kidding me? We came here for nothing! Just to see Discord still as a statue! Thanks a lot Twilight." Fluttershy interfered, "Well Twilight was scared. It's not exactly her fault." Applejack agreed, "It ain't he fault at all. It's gettin dark." She looked up and continued, "At least I think it is. We'll just sleep here. Good night, y'all." They all said, "Good night." Twilight is the only one who didn't sleep. This doesn't make any sense. Why are the clouds still like this? Why is the lightning attack Everypony? Twilight let the shield go and there was no lightning. She sighed, "Maybe it was just a normal storm. Or worse my imagination, well I have nothing to do know but sleep." When she turned around the statue smiled at her. She jumped and turned around. Twilight rolled her eyes and went to sleep.
*Midnight*
The statue shined a bright dark purple. Then Discord appeared and stretched. He laughed, "The Mane Six is trying to foil my plans again. Not this time, I hope you have a good sleep my little ponies; because in the morning there's going to be a lot more chaos." Discord laughed and went towards the castle.
*Inside*
He went into the Princess Luna's room. Her room was really dark and not as decorated as Celestia's room. It could be because; she has been on the moon for thousands of years. Discord went by her bed side. His eagle claw started glowing and he touched her head. Luna's eyes shot open. She got up and noticed her body started glowing. She asked, "Discord, what it thou doing?" Discord answered, "Bringing back an old friend." Before she could say anything her body got surrounded by the glow. A sparkling purple glowing mist twirled around her. When the final glow ceased, Luna's laugh was familiar. Her horn glowed and it got even darker out. Discord bowed and said, "Welcome back, Nightmare Moon." Nightmare Moon looked at him suspiciously and asked, "Have we met?" Discord explained, "Not formally but I've heard all about you, big fan really." She thought for a moment. She asked, "Why did you bring me back?"
They heard Celestia in the hallway. She asked, "Sister is that you? Is everything alright?" Nightmare moon mimicked her original voice, "Thou are alright. Go back to slumber thy sister." Her sister's shadow got closer. Her horn glowed and she turned back to her normal self. She said to Discord, "Leave out now! We shall discuss plan at noon." Discord left out her window. Celestia entered her room and asked, "Luna who were you talking too?" Luna answered, "No one my dear sister." Celestia raised an eyebrow. She questioned, "You aren't lying to me, are you?" Luna had a huge lump in her throat. She answered, "Tis not speaking a lie. Thou speaketh nothing but the truth." Celestia shrugged it off. She announced, "I'm about to raise the sun. I thought since you've been gone for thousands of years, maybe you want to come and watch." Luna's eyes glowed a bloody red. She shouted, "DO NOT VEX MY NGIHT!" Celestia's eyes widened.
Luna's horn glowed and she transformed back into Nightmare Moon. Celestia gasped, "What? I don't understand. I thought you were gone for good!" Nightmare Moon laughed as she wrapped Celestia in some rope. She quipped, "You can't get rid of perfection." Celestia struggled to get out of the rope. She was about to use her magic. But, she remembered that her magic is useless. She asked, "What do you want? You already tried to bring everlasting darkness." Nightmare Moon laughed, "Yes I have tried. But, now I want to rule over all over Equestria." Celestia smiled, "How're you going to do that? Twilight and her friends will wield the Elements of Harmony again. If they defeated you before, they can do it again." Nightmare rolled her eyes. She leered, "I have an accomplice. He helped turn me back to who I truly am." On cue Discord came back in front of the window. Discord noted, "Actually we are going to rule over Equestria." Nightmare Moon levitated Celestia over to the Royal Vault.
Discord went in front of her. He quipped, "Why lock her in the vault? Don't you think it would be better if she stayed with us? It would be fun seeing her squirm as her kingdom falls. Nightmare Moon smiled and nodded in agreement. She looked outside and saw Twilight about to wake up. She shouted, "We'll keep her in the vault for now. Twilight Sparkle is about to wake up. You need to go back down there. I'll greet her and her friends." She transformed back into Luna. Discord flew out the window, got onto his pedestal, and turned back into stone. Celestia shouted, "You won't get away with this." Nightmare quipped, "I was waiting for you to say that. It's going to be so much better when I do." She laughed and teleported herself outside of the castle.
What do you think should i continue? This is just a one shot thing.
