Dark Magic

Twilight woke up in cold sweat. It was early morning, and the sun was barely peaking over the horizon. Twilight took a moment to calm down before looking around her bedroom. Spike was asleep, a Power Ponies comic covering his eyes. Giggling to herself, she got out of bed, almost afraid to go back to sleep. She laughed when she saw her mane. It was a mess! After brushing it out, she looked over to her bed. That was a mess, too. Sighing, she folded the sheets and straightened the blankets.

***Later that day***

Twilight grabbed her book and snuck down into her basement. As long as her friends or Spike didn't come down here, she was good. She would have waited till night, but all the things she could use this magic for made her want to practice. Opening the book once more, she flipped to the second spell. 'Imitation'. After reading through it, Twilight realized this was identical to the spell Queen Chrysalis and the Changelings used. And now that she thought about it, didn't King Sombra use the Dark Crystal spell? Did using these spells make ponies evil? No! Twilight thought. I'm using these spells for good! Looking back to her book, she continued reading. The spell seemed quite simple. All she needed to do was think about the pony she was imitating while casting the spell on herself. So who should she imitate? Spike would be the least suspicious, should she be caught. Concentrating on the image of her assistant, she closed her eyes and set her horn alight.

Twilight almost screamed as a burning sensation overtook her body. Then she burst into green flames, and the burning intensified. Twilight felt herself shrink, and her horn disappeared. Her mane formed four emerald scales. and her tail transformed into a dragons. Spikes popped out of her spine, and claws emerged from her hooves. Scales grew out of her body, replacing her coat. Her ears shaped into the light green fins and she felt her muzzle shrink. Then finally, the green flamed disappeared.

She was on all fours still, but she felt it was more appropriate to stand on two legs. She looked at what would have been her hooves, but they were claws. She looked over to her book and attempted to levitate it over. Then she realized: She didn't have her horn. How was she supposed to turn herself back? Franticly reading through it, she found her solution. 'If you happen to be in the body of a Pegasus, Earth Pony, or other non-magical creature, to return to your body, say Eurt Mrof while concentrating on what you look like.' Relived, Twilight did just that.

The green flames engulfed her once more. She felt the purple scales fall off, revealing her violet coat. Her tail turned back into hair, and her mane grew out of her head as the green scales fell to the ground and were devoured by the flames. Her muzzle grew slightly larger, along with the entirety of her body. Her claws melted into hooves, and her horn sprang out of her forehead. As the burning sensation diminished with the green flames, Twilight was pleased to find herself in her own body again. And just in the nick of time. Spike came rushing down the stairs. "Twilight! Me and Rarity are gonna go- wait, why are your eyes green? They look like mine." Twilight gulped. Her eyes were still Spikes! "Its, um, a side effect. From a spell. Yeah, the, uh, Transfiguration spell, heh." Spike raised an eyebrow, but didn't ask any more questions. "Anyways, me and Rarity are going Gem Hunting. I'll be back in an hour or two." Twilight giggled. "Are you?" Spike blushed slightly. "Okay, you can go." Spike smiled. "Bye Twi! Hope you fix your eyes soon!" Once he was gone, Twilight let out a sigh of relief. He suspected nothing. "Eurt Mrof." She muttered and closed her eyes. Her eyes flashed green and were back to normal.

There was a knock on the door. Twilight rushed upstairs and pulled open the door, expecting there to be pony wanting to check out a book. Instead, there was a tall white alicorn. "P-Princess Celestia?!"
