Betrayal

Chapter 1

    Nightmare's voice traveled through Twilights mind, as the shadow filled Twilight's heart with darkness. Laughter began to fill the atmosphere. Twilight wasn't there anymore, instead; she was Nightmare Sparkle.
Twilight was still herself, she didn't transform completely, she could change into Nightmare a Sparkle whenever she wanted to. All though there was still nightmare voices inside her head.
Twilight preformed powerful magic that she practiced for moons.

The world around her swirled. It swirled in a flurry of white grey. Was this a dream? Was this death? She was faintly freed of this hell; and then came nausea. She wanted to hurl, hurl, hurl! But there was nothing. Stars exploded before her eyes, before her vision shifted before her eyes.
No longer was she on the moon. For that orb was a distant glowing one high in the sky up above.

As Twilight opened her eyes she was in the Everfree Forest, right by the exit.

  Twilight panted hard, her lungs burning for oxygen as I dashed into the woods. Pain ran up through her hooves; The ground and rocks bruised and cut Twilights hooves, the branches whipped her face as she ran towards the exit of the forest.
As Twilight opened her eyes once more after she blanked. She was still in the Everfree Forest, now right by the exit. She Trottes out of the forest, hiding herself away from the ponies.

Twilight ran behind a tree and saw her 'friends' with somepony else...
Did her friends forget about her? Did they just replace her?
Anger swelled through her heart. Darkness comforted her..

"Get revenge."

  The nightmare whispered through her brain. Tears ran down her face, she was pissed off. Why would her 'friends' do that to her?!

Twilight ran back to the forest, grabs a cloak to hide her whole pony body and face.
She walked through the town, nobody was noticing her.
As she strolled down the path, Twilight saw her friends having a great time without her. Twilight felt angry, betrayed, and sad.

Her heart was filled with jealousy, and complete darkness.
Twilight had no clue what to do. Spy on her 'friends?' Or get revenge right away.

'Why was I banished to the moon?!' Twilight thought.

"Hey are you new to town?" A blue rainbow pony asked the cloaked figure.

"Uh y-yes I-I am" Twilight stuttered.

"Welcome to ponyville!" Pinke Pie shouted, jumping up and down.

"Why are you wearing a cloak, Dear?" Rarity asked.

"I-I have to go" Twilight didn't know what to say, she didn't know what to do, she only ran.

She was right by the Everfree Forest once again.

"I'm ready Nightmare" The Alicorn said.

Twilight was now in Ponyville and started to turn the sky purple. (I accidentally deleted chapter 2)
