MY LITTLE PONY: Repercussions of Banishment

Twilight Sparkle waited. The light above her blinked and sparked out of the air. There was Nightmare Moon in the castle. She didn't see her, but had expected her now for days. Her warnings to Princess Celestia were not listened and now it was too late. Far too late for now, anyway.
Twilight was a student for fourteen years. When she was young she watched the sunrise and she said to dad "I want to be magic daddy."
Dad said. "No! You will be KILL BY NIGHTMARE MOON"
There was a time when she believed him. Then as she got oldered she stopped. But now in the ancient ruins of the Royal Castle she knew there was Nightmare Moon.
"This is yourself" the spark crackered. "You must fight Nightmare Moon!"
So Twilight gotten the Emelents and magicaed up the vortex.
"SHE GOING TO KILL US" said Nightmare Moon
"We will gallop at her" said the moon mare and she charged. Twilight teleportaled behind her and tried to activate the Elements. But then the Elements broke and they were stalled and not able to kill.
"No! I must use the Elements" she shouted
The spark said "No, Twilight. You are the Elements."
And then Twilight was friendship.
