My hooves stomped the ground of their own accord, the clang of metal against the ground hidden by Nightmare Moon's expert illusion spell. We had split up to enter the crowd as newcomers to Ponyville. Nobody questioned us as we mingled in. I was impatient, but I knew early exposure could spell doom for our plans. It had to go perfectly. This day was a while coming, and it would be sweet as candy to me. I sighed, waiting.

The wait felt interminably long to me, but Nightmare Moon swears it happened only a few minutes after we got into position. Fluttershy, as usual, was doing music, and Rarity had outdone herself on the decorations, while apparently it took an entire weather team to do what little Dashie could've done in a few moments in an entire day. I almost broke down, knowing exactly why she couldnt've done that this year. Applejack was still doing food, and Pinkie Pie had overseen the entire thing in my absence. Somehow, that worked out, but I was too busy to question it, and anyway, you just don't question Pinkie. Ever.

Mayor Mare, obviously, gave the expected speech she gave every year, and out walked Celestia. As she walked out onto the balcony like she did every year, it wobbled once, then all the supports broke as one, hurling the confused alicorn through the air. In an instant, Nightmare Moon dropped the disguise and launched after her, teleporting them both as soon as she touched her. We had planned beforehand where we were going, so I immediately popped my own teleport spell, throwing myself instantly to the Canterlot Palace dungeons.

Nightmare Moon had already magically sealed Celestia's horn, throwing on a total magic supression ring for good measure, and popped out of the cage before I got there, and Nightmare Moon dropped my disguise as I appeared. I smiled banefully at her as the recolorings seemed to melt off my body. To her credit, she gave no outward sign of surprise until it was over, and there stood her "faithful student." I had to laugh.

"My, my, princess, you seem to be in a little bind, here. Shame you sent your precious, faithful student to the moon. Maybe she could help, if she were still around," I mocked her and her decision ruthlessly, taunting her. Nightmare Moon had taught me some torture spells, and I wanted to try one out. I looked up to my new teacher, and she gave me a nod.

"Ready for the time of your life, 'princess'," was all I offered as I channeled magic through my horn. But, just before I began, I chained her to a wall, overpowering her physical strength with my magic. She was thrown against the wall in the most brutal of manners as the manacles locked her forehooves high above her head. Any normal pony would be dangling off the wall, but alicorns had always been bigger than the average pony. She could see the blade now, knew what I was about to do, and turned to face me, a pleading look in her eyes.

"Twilight, please, rethink this madness. We can go back to the way things were, and I promise never to make any kind of advance until you're ready for it," she begged, tears already forming in her eyes. However, I just walked closer, the sword behind me swinging around with brutal force, causing wind to whip up in the room.

"You had your chance to be sorry. Instead, you banished me to the moon. Now, I've come to exact revenge, and you plead for MERCY?! Really, I expected more composure from you," I showed no remorse as I advanced, the blade coming ever closer to the bound princess. With a lunge, I slammed the blade into her chest, and revelled in the scream. Alicorns, it seemed, weren't immune to pain, either. The blade spell was a piece of work. It couldn't cut anything, being an entity of pure magic, but it did damage to something a lot more precious. Your very soul, your essence, is scarred the moment the blade touches you. Your spirit is sliced to ribbons, then pieced back together to try and hold in the pain, only to be sliced into tinier ribbons as waves of pain wracked your body.

"I honestly can't say what I love more. Nightmare Moon, or the sound of your screams. So sweet, so...rewarding. It makes my trip to the moon all worth it," I wrenched the blade through her chest, then tore it out, dispelling it before moving on to the next act I had in store. I took one of the swords from my hip and glided it over to Celestia.

"That tore your soul apart, and this will make sure nopony loves you ever again," I cried out, my pain from our relationship being severed as it had been ringing clearly through my voice. I raised the sword, then dragged it across her muzzle, letting the tip cut in a little. She was panting, still wracked in agony, as she should be. I suddenly sliced the sword up her face, cutting across her left eye.

"Bitch. I. Hate. You," I meant every word, following it up with the hilt of the blade bashing brutally into her muzzle. She seemed to realize exactly how far gone I was and lay there, against the wall, completely and utterly defeated. I walked up to her, sheathing my sword, and reared up, slamming my metal-encased hoof against her muzzle, returning the slap she had given me all those weeks ago. Then, I turned around, bracing my forehooves and gathering all the strength I possessed. I looked up at Nightmare Moon, and she nodded. However, I decided to switch tactics mid-thought. I had one more way to destroy her, and I knew just what to do. I walked over to the bars of the cage.

"Come here, please, my love," I whimpered, acting helpless. Really, I was just flaunting our relationship in front of her before I finished torturing her. As Nightmare Moon approached, I kissed her on the lips. It was all for the sake of sweet revenge, but that didn't mean I couldn't enjoy my lover's kiss. I pushed my tongue against her lips, and she opened for me. We kissed for what felt like eternity, lost in each others' eyes. We broke apart after a while, and I approached Celestia once more.

"That could've been you, dear princess. But don't worry. Nightmare Moon's taking good care of me now that you're out of the picture." With that remark, I turned again, building strength. I needed a lot of it to lift these behemoths on my rear hooves the way I wanted to. Adrenaline made it easier, but in a scenario like this, I had to work for it. I closed my eyes and concentrated. Then, as my physical power built to a threshold, I unleashed it all in one move.

It was simplicity itself. I simply bucked the shit out of Celestia's chest.

Author's Note

As I said in that comment, I hope the infliction of agonized rage I placed on Twilight is taken well. I have seen sadistic Twilight before, but never a brutal, over-the-top Twi like this one. I hope I stayed a little bit in character even as the darkness took her more and more completely. As always, reviews welcome :D
