Starlight was walking around the castle, checking every room. She was searching for Twilight who she hadn't seen in a few days. Starlight was about to give up when she ran into Spike. He was dusting off the shelves in the castle's library.

"Hey Spike, have you seen Twilight?" Starlight asked as she trotted on over to him.

"I saw her leave the castle early this morning, she seemed to be in a rush." Spike had answered Starlight without breaking his focus.

"What! She's just gone again?" Starlight seemed disappointed, she was neglecting Starlight once more. Twilight had been disappearing everyday for unknown reasons. Starlight rolled her eyes and sighed.

"Well what do I do now? Don't have anything to do since I expected Twilight to have some lesson planned out for me!" Starlight was frustrated, knowing it was going to another boring day.

"Thorax is coming to Ponyville for a few days, wanna just hang out with us?" Spike had stopped dusting and was now walking towards the door, Starlight following right behind him.

"Really? I haven't seen Thorax since the invasion!" Starlight said excitedly.

"Well then we better get down to the train station, Thorax's train should be here soon." Spike had made it to the castle's front doors and starlight nodded. Both of them took off not knowing that Twilight had been there whole time. Twilight watched as the castle doors closed and waited to make sure they had left. when she was satisfied that she would not be disturbed, she turned around and made her way to an empty wall. Using her magic she reveled a secret door, one she had purposely hidden. Twilight walked inside, concealing the door behind her once again. The room was quite large and held a bunch of machinery at the back side. On the left wall were cages, only the door of the cage had the classic barred look. The other sides of the cages were just walls. The right of the room sat a desk and shelves. Twilight made her way over to the desk, grabbing a book in her magic. Setting the book down, her attention went over to the machine parts scattered on the floor. Twilight stared at it before returning her attention to the book she had grabbed. The book one of the many Twilight had retrieved from the castle of the two sisters, this book held the secrets of dark magic.

"This better have something useful, it took forever to find it." Twilight had unknowingly whispered to herself annoyed. She carefully looked over each page, before stopping at one that had piqued her interest. The page held a spell that would allow her to move the corruption of one magic item to another. Twilight thought about this for awhile before she put a tab on the page and closing the book. Twilight got up and walked over to the machine and began work on each part.

"Wow. this place is huge!' Thoarx was already excited about being able to see friend and when Spike told him Starlight was joining them he was bursting of energy.

"It sure is, let's get you settled before we-" Spike cut himself off when he noticed Twilight. She had come from seemingly out of nowhere. All three watched as Twilight stopped and glanced at them. She looked over at Thorax before speaking.

"...I'm glad you found something to do Starlight, sorry I've been busy." Twilight had said that with fake concern. She didn't care anymore.

"pfft, I understand. Being a princess must be very time consuming." Starlight motioned her hoof in a don't worry about gesture while she spoke.

"I didn't know that Thorax was coming to visit...actually can I speak to you in private for a second?" Twilight had lied about what she knew, and now he was here.

"Oh uh okay." Thorax sheepishly responded. Thorax followed behind Twilight into the throne room. once the doors closed Twilight looked over at him.

"I'm sorry I had to ask for privacy, but I don't want to cause a panic." Thorax could tell that this was serious. He held his full attention towards her now.

"Oh. don't worry about that, why did you want to talk about?"

"Well I have been receiving reports of rouge changeling. We don't know who or why they are here, but I was wondering if you could keep a lookout for any strange or suspicious behavior. I figured since you are changeling, that you would know what to look out for."

"Oh, okay..." Thorax didn't want to have to turn in his old hivemates, but he knew that they were a danger to the ponies.

"Thank you Thorax. Please keep this information between us until the issue has been settled. You may leave now." Thorax bowed in respect before he making his leave. Twilight smiled as he left. There was no rouge changeling to worry about. She lied so that Thorax would be on edge. Twilight made her way to the throne room door and walked out. She saw the three make their way down one of the many hallways. Once they had left Twilight's sight she quickly trotted over to the castle's front doors, leaving without making a noise.

Twilight wandered around ponyville for a bit, before making her way over to Sugarcube corner. Walking inside she smelled the many tasty sweets. Twilight walked up to the counter, before she could ring the bell on the counter. Pinkie pie suddenly jumped out from behind the counter.

"Hiii Twilight, what can I get ya today." Twilight was not amused.

"I'll have a large slice of the double cherry cake." She answered as she put ten bits on the counter.

"ONE LARGE SLICE OF DOUBLE CHERRY CAKE!!" Pinkie yelled towards the kitchen. She then rang up the order and placed the bits in the register. Before running into the kitchen. Twilight walked over to the window looking outside. She noticed Zecora walking by. A light bulb went off in Twilight's mind, she would have to give Zecora a visit soon.

"Here is your order Twilight!" Pinkie had walked up to Twilight, holding a box in her hoof. Twilight took the box in her magic. 0She then opened it to look over her cake. Satisfied she closed it once more. She was about to thank Pinkie when she saw that her friend had ran back into the kitchen. Twilight walked out and deciding where to go next.

It was late into the evening, but Twilight had made her way over to Ponyville's schoolhouse. It was late so nopony but Cheerilee should be there. Twilight took a peek inside to make sure that Cheerilee was in fact alone. Cheerilee was at her desk, planning for tomorrow's test. Twilight made her way inside.

"Twilight! How can I help you today?" Cheerilee looked up and had a bright smile. Twilight smiled back. before grabbing Cheerilee in her magic.

"Twilight what is this?" Cheerilee was beginning to panic. Twilight walked over Cheerilee's desk and took a wooden ruler in her hoof. She looked it over for a second as she made her way to where Cheerilee was being held.

"Twilight why are you doing to do?" Cheerilee shaking with fear. Twilight was standing in front of her now still looking at the ruler in her hoof. Twilight was swift in her movements, she struck Cheerilee with the ruler over and over. Cheerilee was now crying and screaming with each impact. It didn't take long for the ruler to break. Twilight didn't care, she just started using the broken ruler to stab at her victim's skin. Blood started leaking out as Cheerilee's bruised skin was pierced. Twilight stabbed Cheerilee's shoulder with so much power that the ruler was now stuck there. Twilight still holding Cheerilee in her magic, lifted her up into the air. She then slammed the earth pony into the ceiling before letting her fall to the floor. Cheerilee was screaming for help, she begin to crawl over to the door. Twilight paid her no mind and looked inside Cheerilee's desk, inside one of the draws held scalpels for safe keeping

"You asked me why I'm doing this.." Twilight had said while lifted all the scalpels in her magic. Cheerilee tried to get up, but she was starting to become dizzy due to the beating and blood loss. Twilight walked in front of Cheerilee and looked her directly in the eyes.

"Well I need somepony to die, and you just happen to be alone. That is why." Twilight stated in calm tone. She then pressed all the scalpels in a different part of Cheerilee's skin. Dragging them back and forth, slicing her skin into ribbons. Blood pouring out onto the floor. Cheerilee was screaming her lungs out now, tears filled her eyes and her body was convulsing due to the pain. Twilight stopped and dug the scalpels into Cheerilee's shredded skin. Twilight then sat at her desk and placed the cake box that she got earlier down. Twilight ate her cake while she watched the life drain from Cheerilee. She screamed then whimpered before going silent. Twilight waited a bit longer, making sure that her victim was indeed dead. Twilight took the empty box with her when she left and headed back to her castle, humming as she walked. She knew that she was going to have to prepare for the big discovery of Cheerilee's body.

Author's Note

Note: Sorry the first chapter was short. Since this my first time writing a story on. I'm kinda just experimenting right now. Also this story is kinda a slow burn. I plan to really amp up the violence in each chapter that I write.
