Matriarch

FlashBack

"Ahhh Celestia.... So many memories we put together," Matriarch said," If only you saw things my way, we could have made more memories."
"Ouch.... gee, what was that?" Twilight said to herself,"That was raw power! I never knew it could hurt so much!"
"Oh! It's little Twilight!" Matriarch said with fake glee," Have you ever wondered..." Matriarch used her magic to move Twilight until they came face to face," Why you have never met me before?"
"No, Matriarch!" Celestia said with panic," The truth could destroy her!"
"Oh shut up, Celestia! I'm not that ignorant filly anymore! You don't control me!" Matriarch said," As I was saying..."

Equestria

1000 years ago

"Sister, have you ever.... say.... gotten rid of the Equestrian failures?" Matriarch said.
Celestia's face contorted with disgust," Matriarch! Why in Equestria would you say that?!"
"I mean, we don't need them, we don't want them, so why are they here?"
"Matriarch!"
"Why don't we recycle them? Like make other uses for them?" Matriarch asked.
"Recycle? What in Equestria do you mean, Matriarch?!"
"I've been talking this over with Luna, and she seems to agree with me." Matriarch added
"We've been thinking, we ground up worthless ponies into rainbows, so we can make the ponies with worth to us happy! Celestia, it's a great plan, although, I haven't talked to Luna about it..."
Celestia stood up, and slapped the orange mare.
" I never want to hear about it ever again, Matriarch! If we did something as awful and as sinful as that, the society of Equestria would fall!"

But Matriarch went through with it...

"She did what?!" Celestia demanded.
"That's right.... she killed them to make rainbows..." Luna said, feeling sick to her stomach. When Celestia heard this, nopony had ever seen her this mad before.

Then Celestia got a hold of Matriarch...

"Matriarch, I can't believe you would do this. As punishment, you are hereby banished from Equestria...FOREVER!!!"
"You can't b-banish me!" Matriarch's voice quavered,"I'm making everypony happy..."
" I can,and I will banish you, and to make sure you have learned your lesson..."
Celestia pinned down Matriarch, then then grabbed Matriarch's left wing and tore it off her body. She did the same for Matriarch's right wing. Then, Celestia pushed Matriarch to the ground, so she couldn't get free. The she stepped on Matriarch's horn, snapping it in half.
"C-Celestia! Why would you do this to m-me? I loved you!"
"I used to love you back." Celestia said," But you aren't a part of me anymore."
Celestia walked away from the sobbing, bloody, mare.
"CELESTIA!!!!!!!"

"Ever since that day, I've wanted to do the same thing to you, but I found an even better plan," Matriarch looked at Twilight.
"Here's the deal, you cripple me, I cripple your faithful, little student."
