Lightning Dust has no friends. So when she finally acquires one, she wants her all to herself. But Spitfire will not tolerate that behaviour. After all, Fleetfoot is a Wonderbolt too.
Rated Teen for Nightmare Moon. Because otherwise she'd kill me. 
Joking. :)
Lightning Dust scuffed the ground with her blue hoof. Fleetfoot should be here. She search the grey-tinged clouds for a blue streak mixed with white. Thinking back on the day she had met Fleetfoot, Lightning Dust smiled. Fleetfoot was a great friend. Meeting Fleetfoot had been pure luck. She was the only pony who didn't think she was horrible, even thought she knew Dust's past. Ahh, those were the days.
Fleetfoot had been walking along the main street of Ponyville near the Town Hall when she met Lightning Dust, that fateful day where their lives would be entwined forever. She had seen a pegasus being bullied. The pegasus' fiery mane had been limp and her eyes had no sparkle. Her hooves had been dirty and her wings had dangled uselessly by her side. After Fleetfoot had rescued her, she still didn't look up, not even after Fleetfoot had said, "You need to stand up for yourself, kiddo. The world isn't a kind place." Finally, the mare had looked up and Fleetfoot had realised with a shock that the pegasus was Lightning Dust! For readers who are wondering, 'Who on earth is that?', Lightning Dust was a student at Wonderbolts Academy, and one of Rainbow Dash's friends. But one day, she went too far and created a tornado. Rainbow Dash owned up and told Spitfire. Lightning Dust was kicked out of the academy. No one has heard of her since as she hasn't been in any other shows as far as I know. Back to the story. Lightning Dust had looked surprised too.
"Do I know you? she had asked. Fleetfoot had shaken her head. "Um, thanks. You know, for saving me back there. Um, want to grab a baked chestnut or two?" Fleetfoot had giggled inwardly at Lightning Dust's pathetic attempt to make friends.
"Thanks, Lightning Dust," she had replied. "I'd love a chestnut." Lightning Dust had gasped. Fleetfoot had laughed again. "Yes, I know you. What Wonderbolt doesn't?" Seeing the look on Dust's face when she realised she may have lost a friend, she had added,"But don't worry, I won't abandon just because of one little thing. Every filly makes mistakes. Colts, too." She had led Lightning Dust to a stand of roasted chestnuts. Lightning had blushed when she discovered that they were roasted chestnuts, not baked. Fleetfoot smiled. She had made a new friend.
Spitfire groaned. Fleetfoot was late for practice. Again. Her hooves tapped as she wondered what was keeping her. "Team!" she yelled. "Start routine. I'll be back!" Speeding off, she looked at an aqua mare with an orange mane playing with a blue mare with a white mane. She suddenly pulled up. "Fleetfoot! Back to training! And you," she pointed at Lightning Dust," are banned from Cloudsdale! Remember?" Lightning Dust flared up.
"Fleetfoot is my friend, not yours!" she cried. "She would leave the Wonderbolts for me! She doesn't have to follow your orders, because she's"STAMP"not"FLAP"a"STAMP"Wonder"STAMP"BOLT!!!!!!!" Spitfire gasped.
"Is this true?" she asked Fleetfoot, her voice quavering. Fleetfoot shrugged. Then Lightning Dust dragged her away, while Fleetfoot begged her to let go. "It won't work," Spitfire mumbled to herself. "Wait and see..."
Lightning Dust dumped Fleetfoot on the floor. "Please, Dusty, stop!" cried Fleetfoot.
"Not until you leave the Wonderbolts for me," Lightning replied. She bound and gagged Fleetfoot and tossed her into the corner. "You're a traitor.You didn't say it was true, you shrugged!" Fleetfoot cowered in fear. "I'll come back in an hour and you'll tell me!" cried Dust. "I have work."
One hour later(I think)...
"So?" cried Lightning Dust.
"I would, I would!" screeched Fleetfoot. Lightning Dust nodded. Then she left Fleetfoot in the dark, damp house.
"Now, Spitfire, Fleetfoot agreed!" crowed Lightning Dust. "And I will rule Wonderbolts!" She sat at Spitfire's desk.
"No," said Spitfire. "Fleetfoot only agreed because she was afraid. Get that!"
Spitfire rushed to her old friend, Fleetfoot. "Are you alright?" she whispered. "Don't worry, not only has Lightning Dust gotten a 6-year sentence in jail, she is banned from all pegasus cities." Fleetfoot sat bolt upright.
"Jail?" she cried. "That will not hold her in, nothing can! She is the spawn of nightmares, she cannot! Nightmare moon will fetch her, be sure of that! Oh, glory, help us! We will all-" Her voice was cut short as the ambulance flew away. Spitfire was scared. What was wrong? Nightmares? Spawn? Was that a prophecy? What could possibly go wrong, what happened?
"Ah, my child, born to do wrong in the world," rasped Nightmare Moon, who had by now separated herself from Luna entirely. "It is time, and fitting, that you should take you true form. Let me help:
Midnight, nightmares,
Moon and hatred.
Mixed together
In a combination.
Throw away
The pixie dust.
Time to take
On your nightmare lust.
Storms, battles,
Lightning, moon.
Time to wreak havoc
Very soon.
Ha ha ha!" Her laugh echoed around the barren castle. "Soon, you will come, with an entire army behind you."
Miles away, in a jail cell, Nightmare Storm awoke.
I will rise, the time is now, thought Nightmare Storm. Ready, 3, 2, 1, he's coming! The jail master fell without a sound.
"Jail mates!" she cried. "I give you the chance to have revenge! All you have to do in return is let me and my mother lead. We will take over Equestria and rule forever! Wahahaha! Ha ha ha!" An uproar was made at her words and the army was formed.
"At last!" rasped Nightmare Moon. "My spawn, my child, she has made her move. She has them wrapped around her horn! She takes after me, her mummy, doesn't she? Well, who else could she take after? She has no father! Nightmare Moon created her out of magic!" Her evil laugh echoed through the dim, gloomy night. My domain. My world. And soon, my future, thought Nightmare Moon. Her new future. The words tasted good on her toungue. She could see it. Her daughter, leading them all, with Nightmare Moon as he 2nd. I've had my turn, thought Nightmare. But I'm getting another chance...
