Chapter 1
It was late night at Canterlot High School, and everyone had already abandoned the building for going back home, including Twilight and her friends. Principal Celestia had asked Vice-Principal Luna to check everything at the different rooms inside the school, which Luna accepted to do. With that, Celestia left for going home as well.
"Ok, it's time to be the security guard. I wish this was a museum, it would be fantastic." Luna said, as she got prepared for her surveillance.
Before heading towards her office, she locked the front doors, just in case someone tried anything. The most likely scenario was a robber entering for stealing one or more computers, but Luna feared something even worse could happen. Because of that, the front doors would stay locked. She also disconnected the lights, but not all of them. For the hallways, she would have to use a flashlight.
Upon arriving at her office, Luna got the flashlight and went to check the rest of the rooms.
She started by the cafeteria. Nothing certainly interesting besides one slice of pizza on one of the tables.
Having checked the kitchen, she only saw a hamster eating some lettuce.
She also looked on the library. Books stayed there, and the computers were all disconnected except for one. Luna noticed a lot of pages were open on that computer, and they all were about science.
"Twilight Sparkle is sure a good student. I don't think she ever got bad grades." Luna said.
Then, she looked inside the gym. Rainbow Dash had left some things out of their boxes, like some balls, jumping ropes, etc. Luna took some time to get everything back on its place, which she managed to do.
"I will have some words with Rainbow Dash tomorrow." Luna told to herself.
At the music classroom, she found nothing unusual, and the instruments looked well, so she didn't touch anything else and went to look at other places.
Finally, she checked the different classrooms. Normally, a few students left something forgotten, like a pencil or a book. And usually, those students happened to be Snips and Snails.
After a while, Luna went to check the labs. Almost everything was on its place, with a few exceptions. Science books, flasks and more things filled the shelves waiting to be used.
On top of a desk, Luna saw a flask, the content of which was a green liquid.
"This doesn't look like any experiment the students have done." She said, as she grabbed it to look at its content.
To make sure the liquid wasn't dangerous, she made one or two drops of it fall over her arm. It did nothing, so there wasn't any problem.
"If it was an acid, it would have left a few wounds on my arm." She said, looking at the flask once more.
Just then, she made a clever movement: as nobody else was there, Luna drank some of the liquid.
"It tastes... good, I have to say." She thought. The flask fell to the floor when she realized something: her entire body was getting... bigger? And her hair was also getting longer.
Also, the belt and the buttoned shirt she was wearing had started to change. The belt bended down, and the shirt's neck two ends fused together, the moon standing on the front of it. All of that while that buttoned shirt was also growing bigger and the sweater was modifying its design, slowly turning into a dress...
"This feels rather good! Wait for when Celestia sees this, cause she is going to be jealous!" Luna said, happy because of what was happening.
On a mirror, she stared at her reflection, looking at her body as it constantly changed.
And then, something strange took effect: her skin color started to go darker and darker each passing second, and her nose turned into a snout. A pony snout.
"Huh? I don't think this should be part of the experiment." She said, still looking at her reflection.
Canterlot High School, a place where magic events are common, from Sunset to Wallflower, from Midnight to the Dazzlings, from Twilight to her friends, etc.
Well, another one of those things was happening at the labs right now.
Vice-Principal Luna kept staring as her body didn't stop switching: her clothes were creating some sort of dress; her skin was getting even darker; her hair was growing longer, also turning as a dark as a
night sky with stars; and her human head transformed into a pony one as her ears and snout got bigger. Finally, a horn appeared on top.
"I must admit I am feeling rather good with this." Luna said with a smirk on her face.
While her body shape-shifted, two extra things formed on her back. She identified those as a pair of wings, which were slowly opening as the transformation kept going.
Meanwhile, the buttoned shirt she was wearing also had another detail: sleeves were forming around Luna's arms, and they covered everything from forearm to her hand, like two long gloves.
"This sensation... I feel the power!" Luna said.
Her skin went totally black as her long hair flowed like the wind. Her clothes finished changing, with a few details here and there, as the belt and the neck bended themselves, with another moon appearing on the belt. At the end, her head looked like the one of a real pony. And her fingers seemed to turn into claws or, at least, pointy fingers.
And those changes on her body made her look even taller than before.
Vice-Principal Luna was liking this. In fact, she was enjoying it. Although the vice-principal wasn't there anymore. Taking her place, was a dangerous being.
A being feared because of her bitterness and jealousy.
A being whose origins were a thousand years old.
A being known as "a wicked mare of darkness".
The transformed Luna laughed evilly as her wings fully opened.
"Everyone will bow before me! The mighty Nightmare Moon!"
