Corruptible

A/N: A small side project. Updates will be in a period of every two weeks enjoy.

Summary:

Twilight knew she needed to stop Nightmare Moon, but what she didn't know was all the knowledge Nightmare Moon had about her mentor and friends. Inspired by The Element of Corruption by Fyronarion.

,.,.,

Twilight went to face Nightmare Moon, she didn't want her new friends getting hurt so she went alone. As she entered the Castle, she could feel Nightmare Moon's presence watching her, studying her. She shuddered at the feeling and continued on, looking for the mare of darkness. Her new friends suddenly rushed in and she gasped in surprise,

"Girls what are you doing here, this is dangerous," she said,

"We couldn't let you face Nightmare Moon alone, darling," Rarity said, "so we decided to come help,"

"Thank you," she said, her confidence boosted tenfold. They entered a long hallway to see Nightmare Moon herself at the end,

"Please stop this sentimental nonsense," Nightmare Moon said, annoyed, "I learned you can't trust even your own siblings 1000 years ago,"

Twilight lit up her horn and said,

"It's over Nightmare Moon, the night will end, we're bringing daytime back,"

"Oh yes, Twilight Sparkle," Nightmare Moon said, "my sisters next plaything. But you are different, you are the element of magic. Your ordinary magical abilities are powerful enough but fuelled by the element of magic, you would be undefeatable,"

Twilight lowered the power in her horn,

"What are you saying?" She asked, unsure. Rainbow Dash interrupted,

"Twilight can't you see she's toying with you, just whoop her flank so we can get out of here,"

Twilight turned her head towards Rainbow but said,

"Continue," to Nightmare Moon,

"Only in private, and I know things about Princess Celestia and your friends that you would not believe, I've been studying you over 1000 years. I know a lot,"

Twilight was stuck between what to do, she could get it over with and defeat Nightmare Moon or she could hear her out, in private. Before she could make her decision, Nightmare Moon's horn lit up in a blue aura and she uttered an ancient spell. Twilight heard a creaking, cracking sound. Twilight turned around to see all her friends were turned into stone statues,

"CHANGE THEM BACK!" She yelled at Nightmare who replied,

"Oh don't worry, that's only temporary. Now listen to me, Twilight Sparkle,"

Twilight gulped and said, "okay,"

Nightmare Moon looked pleased and said, "My sister, Princess Celestia has an awful habit of using ponies for a while and then completely forgetting about them. She even partly did this to me. She would make sure she would get what she wanted and if they didn't want to do what she said, she would never help them again. During mine and her rule, she would often use me to cover her own financial and political problems, then blame me face to face for doing it anyway when she knew it was her. She then decided to take on pupils to train in magical arts to get what she wanted quicker, she used so many innocent ponies this way, including one who's now in jail,"

"You're lying," Twilight said, confused. Why would Princess Celestia do such things?

"I am not," Nightmare Moon said then continued, "Celestia then decided to look into the future to see and hunt down the best ponies to train and use. She found you. She made sure you two would cross paths and you would have your magical overflow in your entrance exam so she could use you do defeat me and any others seeking to destroy her. She sent you to Ponyville as she knew you would meet all your 'friends' who are all in league with Celestia and her schemes," Nightmare Moon explained.

Twilight wanted to deny it, she was so confused. She broke down, sobbing and looked at the statues of her friends in hatred. Celestia used everyone to get her way.

Nightmare Moon saw her confusion and knew this was the time to break her, to get her to join her in her efforts to dethrone Celestia. She said,

"I can help you. I have been part of Celestia's schemes too and I know how it feels to be a puppet under her control. If you join me, we can overthrow that demon and restore true harmony to Equestria. Your so called friends only ever talked to you because of your status I. Canterlot. Remember what Rarity said about being so happy about you having a status in Canterlot and saying you were going to be great friends talking about it? Such a great friend, all your friends only followed you because they knew of your status,"

"You're lying," Twilight said through gasps and sobs,

"I never lie," Nightmare Moon said, "I stand firm in belief that false words are true evil."

Twilight was next to crying and in a mental battle with herself;

They only liked you for your status…

Shut up, they're your friends…

They wouldn't be if she was just a commoner…

Yes they would…

I doubt they'd even talk to her…

Twilight looked at her 'friends', burning and bristling with anger. Nightmare Moon held out her hoof,

"Join me and we can stop Celestia's tyranny and rule Equestria fairly, together!"

Twilight knew what the right decision was now, she knew who the real problem was. She grabbed ahold of Nightmare Moon's hoof and a blue cloud passed from Nightmare Moon's horn into Twilight's. Twilight underwent a shocking transformation. She turned blackish purple and gained a red chest plate with the starburst from her cutie mark engraved on the middle. She wore red shoes and her mane turned a purple shade with pink swirls, and where the stripe was down the middle, had turned black and white. Her element, now on her head, changed colours to red. Her eyes turned into like Nightmare Moon's, except they were purple not blue. She grew a tiny bit. Her mane and tail had grown and both had stars twinkling in them. Nightmare Moon said,

"You are now my apprentice, Twilight Sparkle. I will teach you the ways of magic and you obey me alone. Prove your loyalty to me,"

"I will do anything, mistress," Twilight said,minister checking out her new body,

"Anything… Hmmm," Nightmare Moon thought then said, "kill one of your false friends, this will be hard for you but they never liked you anyway, they only were around you for your status, pay them back,"

Twilight gulped and Nightmare said, "use your magic,"

She complied, activating her horn and approaching Pinkie Pie, who was still petrified in stone. As Twilight did her business with Pinkie Pie, Nightmare Moon thought to herself,

'With the most powerful element on my side, taking down Celestia alone should be easy but she has an army of guards. Good thing I know someone with an army too. Twilight will be the best apprentice ever.'

Twilight finished her job and asked Nightmare Moon,

"did I do well, mistress?"

"yes," Nightmare Moon replied, "and call me Moon, not mistress. We want to be friends, correct?"

"yes Mis-I mean Moon," Twilight said,

"good, your new name is Nightmare Twilight, you are my apprentice and are 100% loyal to me alone,"

"yes Moon," Nightmare Twilight said happily. Nightmare Moon was so much nicer then she'd originally thought,

"what are we doing next, Moon?" Asked Nightmare Twilight,

"we are visiting and old ally and friend of mine," Nightmare Moon replied. She had fully convinced Twilight to join her without brainwashing her. She was incredible.
