Nightmare Moon's POV
I use my blue magic to unlock the Canterlot castle doors, smirking as a soft click could be heard. I flick my black ears as I walk through, my icy shoes clicking against the smooth marble floor. A few guards come at me, but I simply blast them away with my long horn. I soon arrive at Luna's door, knocking on it like a maid would. Soon, a small voice calls out, "Come in!" I opened the blue doors, and stepped inside. "What is it?" Luna asks without looking. "I want to prove I am worth something," I reply with an icy voice. Luna turns around to look at me and gasps. "But... But you're me!" She exclaims in shock, her pretty blue eyes wide. "Oh no, I simply took over you. Funny how forgetful some ponies can be," I say, lifting a hoof and looking at it. "Tia! Tia help me!" She cries out desperately. I chuckle. "Nopony will hear you now, don't you think I cast a spell? A soundproofing spell?" I ask, almost challenging her. Luna whimpers, and I chuckle. "Oh, poor little Lully, so scared, so... Pathetic."
Chrysalis's POV
I try changing into many figures, testing my abilities before my raid. I then take a few other changelings to go with me on my attack. They change into royal guards, and I change into Celestia. I teleport to Canterlot, and head up to the castle. I open the large doors, and find some guards, dazed and burnt, laying on the floor. I raise an eyebrow. Somebody had beat me here. I motion to my companions, and they run along with me through a large hallway. I reach a blue door, and open it to find a tall black Alicorn confronting Princess Luna. She had the same cutiemark, just different colors. Something about her, the way her eyes sparkled with the knowledge and love of night, like me. "Who are you?" I ask her. She turns around with a questioning expression on her face. I sigh, and change into my true form. "Nightmare Moon," she replies. I smile as I hear the cold glint of evil in her voice. "Queen Chrysalis," I reply. She smiles back, and I could tell she knew I was on her side.
