The sad part.
Luna : Canterlot hospital:Under her sleeping sister.
Luna awoke under Celestia. At first she thought she was dead, but her loud snoring proved otherwise. She gave her a pat, then promptly shoved her off. She looked outside to check for any more of that "corruption". Surprisingly the sky was clear. Was it a dream? No. The ponies lying in the street shattered that fragile hope. Most were asleep and some had injuries. But a few. A few did not get back up. They never would. She had one thing on her mind. She tucked her sister into bed and headed out.
Stone Blossom: A street corner
She jolted awake. Her chest was scarred over, but other than that she felt fine. Then she realized something. Her armor was gone. Which meant one thing. She won. It was all over. She would never see him again. The thought made her start crying. Here she was, the savior of the world, alone on a street corner.
"Please don't cry," somepony familiar said behind her. She got up and hugged him.
"I thought I would never see you again," she said through tears.
He hugged back. "I thought the same. But now, all of it is gone and we can finally be together!"
She squeezed him tighter, hoping this wasn't a dream. But deep down, she new it was real. "I love you so mu-" she gasped at a sudden pain. A spear passed straight through her chest and into him, then was torn back out. She fell to the ground, dying.
"You to have caused so many lives to be extinguished in so little time," Luna said, so much malice in her voice. "Atrocities that must be punished."
Her Guardian was lying down in front of her, chocking on his own blood. She reached out to him, and he pulled her into him. One last hug until she passed.
"You two deserve this. Though, I am sorry it had to be this way."
And with that, the black veil passed over her eyes once more.
The end.
