	Twilight looked up at Canterlot and focused on her mentor through all the screams and cries, and teleported directly into Celestia's royal hall. "Hello Celestia, it was been too long since I have seen you. I learned a couple tricks while I was away." Twilight slyly said to Princess Celestia.
"Who are you, and what are you doing in my hall...Oh no, what have you done?! Why are you bloody, I demand an explanation for this! Who are you, what have you done, and what are you doing here?" Celestia shouted back at her.
"Oh Princess, you really don't recognize me? You think it would take more than Alicorn magic and the blood of my friends to make your own student completely unrecognizable. But then again, you always seemed very oblivious to what you didn't want to know." Twilight said with contempt. Princess Celestia stood up, her eyes widening, with tears starting to well up in them.
"Twilight.... no... what is wrong with you? Why are you so tall? What happened to your eyes? And why are you covered with blood?" Celestia stammered.
"Look, you disregard what you do not want to hear again. You heard me say where this blood was from. Say it." Twilight replied.
"Your friends... but who, how, WHY?!" Celestia screamed at her.
"Who: Applejack and Spike. How: a shard of crystal and a hoof. Why: Because they got in my way; you are in my way too Celestia."  Twilight casually said back.
"No, you will not hurt anyone else, and you will not take Equestia from me, or me from Equestra, I am ending this!" Celestia roared. Celestia launched a magic wave of light the knocked the tapestries from the walls and shattered all the windows. When the flash left, a dome of shadows as dark as pitch remained in the middle of the hall. When it receded into the floor it revealed the dark from of Twilight, her eyes glowing green through the shadow. 
"Surely you are going to give me a better challenge than that Celestia, or are you just angry at the artwork? To be honest, I never really liked it either." Twilight said as she crushed a shard with her old self on it. Celestia stood, shocked and angry. 
She conjured up a beam attack stammering "It isn't Twilight" and "I won't let the darkness win". She fired off a blast from her horn and Twilight did the same. Their beams clashed as they met, but Twilight's was stronger, and it began to push the beam of magical light back against the protector of the land.
"If this is all you can do Celestia, I am shocked I have learned anything from somepony so weak. I will make a better ruler than you anyway, at least I am stronger." Twilight said as her beam crept closer and closer to Celestia. "I will not let you win, I forbid you to!" Celestia shouted back, and she drew upon her own Alicorn magic; Celestia's was weak and untamed, but it managed to move Twilight's beam back. 
"The thing is Princess, you can't stop me." She put more power behind her beam, and effortlessly drove Celestia's blast back to its source, knocking her back to the ground.
Twilight looked on her fallen teacher without pity, and lashed out shadowy purple tendrils to wrench her onto her back. Celestia looked up at her corrupted and merciless student and stammered, "You are not Twilight...You can't be!" the Princess cried out in anguish. 
Twilight walked up to her old mentor without flinching, and put her hoof on Celestia's chest and said "If it any consolation, Twilight is dead along with her friends. I am Darklight."she said coldly. She began to press down on Celestia's chest, not even batting on eyelash at the cries of pain coming from the helpless Princess beneath her. Her hoof cut into Celestia's skin, staining her beautiful white coat a terrible crimson.  She continued to press down onto her chest, until she heard a piercing snap of a rib cracking, followed by a terrible scream of pain. 
She was continuing to press when she heard somepony yell "Get away from my sister!" Darklight was then struck in the back by a bolt of magical energy, pushing her to the ground.
It was Luna's voice that she heard, so she stood back up saying "Ah, Luna, I was wondering when you would show up. Fashionably late as always I see; this was one party you couldn't afford to miss, however." Darklight said, looking back over at the broken and bleeding Princess Celestia. 
Celestia began to address her sister saying:"No... Luna... she is too powerful.. don't.." In the middle of her warning she was cut off by a shadow tendril piercing through her chest, driving straight through flesh and bone into the ground beneath her. Her final word was a weak and gagged "Run...", as she passed away. Luna screamed and began to draw upon the small amount of the Nightmare Force she still contained in her rage.
"Just what I wanted." Darklight said grinning. As Luna began to transform back into the form of Nightmare Moon, she halted the transformation and drew the Nightmare Force to her. As it entered her body, she felt all the emotion Luna felt one thousand years before; jealousy, anger, sadness, and ambition. She drew upon its power, growing even larger than before, her mane dissolving into pure shadow, darker than any night. Darklight laughed as her teeth became jagged and she became even more powerful than before. "Thank you Luna, you gave me what I needed to secure my place in power; I reward anypony who helps me, sadly, the best reward I can give to somepony with the title of Princess is a swift death." Darklight said with a cold courtesy. At that moment she unleashed a vile pulse of energy, and a sickening slice echoed throughout the hall, as a splatter of blood shot from Luna's neck. Her head slipped off her shoulders, landing with a terrible thud on the ground, blood pooling around it. The look of complete disbelief still shown on Luna's face, even in death. "And now nopony can stop me. Not Celestia, not Luna, and I have even surpassed Discord in my power. This land needed a harder ruler, and the is exactly what I will give them." Darklight said as her began to laugh to herself.
