Matriarch

Chapter 4

"Hmmmm...." Matriarch said,"I'll go for the horn!"
Avia put Twilight on the ground, then Matriarch stepped on her horn. Everything was a blur after that. Her friends screaming, Matriarch laughing manically, Celestia gasping in horror, but Avia was being completely silent. Twilight wondered why, then she closed her eyes, waiting for the sickening snap from her horn. But it didn't happen. In fact, she felt like there was nopony on her horn at all. When she woke up, she saw Avia attacking Matriarch. She was stabbing her with her horn, making a bloody welt wherever her horn was. Matriarch was screaming in agony.
"What in the hay is goin' on here?" AppleJack asked.
"I think..." Twilight started,"She's realizing she isn't the evil Princess Avia, but she's been painted in a new light. She doesn't want to be evil. She wants to be Rainbow Dash."
Matriarch flung Rainbow of her. She was gasping for air.
"What is she doing?" Rarity asked.
"I think Rainbow stabbed her in the lungs!" Twilight exclaimed.
Celestia stood over her dying sister.
"C-Celestia...." Matriarch started.
"Don't speak sister, your life will be over soon."
"I wanted to say... I'm sorry." Matriarch said weakly. Celestia blinked in surprise."About Twilight, about Luna, about the dead Equestrians. I'm sorry about all of that!"
"Why did you target Rainbow?" Fluttershy asked.
"Rainbow Dash was a lot like Avia in her youth." Matriarch said," So I planted Avia's conscience inside Rainbow Dash, hoping Avia would help me conquer Equestria, but Rainbow Dash was extremely strong-willed."
"She is the Element Loyalty in the Elements of Harmony after all!" Rarity said.
Matriarch chuckled,"Yes, I suppose that explains it."
They all laughed.
"Uhhhhh, it's great and everything, but I don't want to be an alicorn anymore."Rainbow said.
Celestia used a spell to shrink Rainbow and remove her horn.
"That's better." Rainbow said.
Matriarch coughed up blood.
"It's time for her to die." Celestia said.
"End me, Celestia."Matriarch said."Kill me, so I, you, and everyone can know peace."
Celestia nodded. She used a spell to give Matriarch a painless death."Love you" Matriarch said. Then she died.
Celestia shed a tear. "Goodbye, Matriarch."

"Have a good afterlife."
