Luna was the first to attack. Her horn glowed with dark power, charging. She let out a scream of hate as she fired at her false sister. Celestia dodged it, laughing evilly.
"Do you really think a little thing like that is enough to defeat me, little sister?"
Luna was distracted by her anger, and Celestia took the opportunity. She charged down at her, forgetting about her magic in her clear insanity. This threw Luna off, and she was easily knocked down, and started bleeding from one of her hooves. Luna cried out in pain and struggled to get up, giving Celestia another chance to attack. Celestia pointed her horn towards her and charged her sun magic, much to a paralyzed Luna's horror. Just then, a high screech could be heard, and Discord flew at Celestia at a speed so incredible it even startled Rainbow Dash, who was holding back a worried Pinkie Pie. Celestia fell over, giving Luna the chance to recover and get back on her hooves. While Celestia was down, Discord clawed at her with pure hate in her strikes, making them all the more powerful, as the other ponies watched from a distance with a cold sort of victory in their hearts. He struck with such speed that it was almost impossible for her to get up again. However, Luna's heart ached at the sight.
"No!"
She rushed towards Discord and shoved him off. Luna had managed to shove Discord only a bit of Celestia, because of his sheer strength, but she had put him off. Pinkie Pie screamed out to him.
"Dizzy!"
Discord looked down at Luna.
"Why in Equestria's name did you do that?"
Luna looked up at him with confused and terrified eyes as tears streamed down them.
"I want her to stop hurting ponies, but I don't want her dead!"
Celestia stood and kicked her sister away into a corner, leaving her defenseless. Celestia walked towards her, looming over her, cackling.
"Your 'love' has made you weak, Luna! It will be the end of you!"
And as Celestia raised her horn towards her, Luna prepared herself for her death.
"All hail Princess Luna!"
As Celestia and Luna looked towards the pony who had shouted that, they could see an earth pony from the crowd rushing towards her. The pony was a mare, and her coat was the colour of poppies, while her eyes were as black as Luna's coat. Her mane was short and brown, tattered by the leaves and branches she had come across. Other ponies followed her, all yelling, and they proceeded to attack Celestia. They fell on her, some biting while others kicked out at her with hard hooves. She screamed with fury, kicking numerous ponies off. Some unicorns used their magic to strike at her, but most couldn't get at her from the crowds of furious ponies. The pegasus ponies looked on from Cloudsdale, most deciding not to get involved, while others flew down and struck at Celestia with amazing speed and agility. After only a matter of minutes, Celestia stopped struggling, and stopped breathing, as the blood loss caused her heart to slow further and further, until there was nothing left of the mad dictator except her tattered corpse. The ponies stopped attacking and backed away, their coats covered in blood, some their own, some of other ponies, but mostly from Celestia. Luna stepped forward, blood still gently coursing from her right hoof.
"...C-Celestia?"
She stepped closer to Celestia, as the other ponies looked down at their hooves in shame. The red earth pony who had sounded the call started to step towards her, to comfort her, but was pushed back by a unicorn, a friend of hers, who only shook her head sadly at her, then looked back down at the ground. Luna, in shock, rushed closer to Celestia, until she was standing above her, looming over her as Celestia had done only a few minutes ago. Luna shook her gently.
"Sister?"
Celestia's head turned in an unnatural way, showing her broken neck. Tears erupted from Luna's face as she became hysterical, shaking Celestia roughly.
"Celestia, wake up! Damn you, wake up! Stop playing with me!"
Luna broke into tears, as the surrounding ponies looked down at the ground, then began to walk away. The new Celestia, the pony who raises the sun, a pegasus, walked out of the crowd and towards Luna, and gave her a comforting nudge. She turned towards him, and began sobbing hysterically on his shoulder. After he'd finished comforting her, he turned towards the group of ponies who had begun to walk away.
"Everypony! I call a town meeting an day from now, in this very spot."
He then turned towards Discord. Pinkie Pie gasped, expecting the worst.
"...Stay in Ponyville for the meeting. I have something to say to you."
With that, he and Luna flew off, leaving all the ponies to think about what had just happened.
All the ponies had returned to their houses to worry about what would happen next. Some, like the red earth pony, were haunted by guilt, while others tried to pretend that Celestia deserved it. However, they all knew that what they did was wrong, whether they had meant to do it or not. Government officials had started to clean the streets, and were about to throw away Celestia's corpse when another pegasus official appeared and whispered into the other's ear. With that unknown message, a group of unicorn officials floated Celestia's body over to a box, which was then carried respectfully towards the palace, where Luna and the new sun pony, Gallant lived. Pinkie Pie, however, ignored the scene before her, and chatted with Discord happily for the rest of the night, as she was just glad he was alright. After Rainbow Dash had seen how Pinkie Pie had run over to Discord and completely forgot about her, she was hurt once again, and flew off to her home, cuddling deep under the blanket, in hopes that the warmth and tranquility of her home would help her forget what had happened. It hadn't. Though some, like Pinkie Pie, tried to remain happy in the face of sadness, nopony slept peacefully that night, some worried about what trouble they were in, while others had their dreams haunted by the sight of Celestia's mangled, broken body, as her eyes stared at them all with a fish-like quality; large and bloated with a madness only she could possess.
