Most don't know what a nightmare force is, and all but one have no idea what it feels like... To have one feeding off of you... But I do.
My name is Luna, and this is my story.
I was unwanted, hated, no one liked my moon, they slept under it, and it made me angry, and sad. And my sister was never there when I needs her... So when Nightmare came... I was lonely and gullible, and I accepted her request. She asked for a spot in my mind, a piece of my conscience, and she got it. At first, it wasn't bad, she encouraged me, and adored me. But then, she began to grow. She stopped being a kind pony, and started harming me. I was afraid, but I was strong. At least, that's what I thought. She told me we were going to attack Celestia, alone. I didn't want too, but I no longer had the control of my body. Nightmare was me, I was now her, just a piece of my own body's conscience, with no control of my actions. Even in my powerless state, I couldn't let Nightmare kill Celestia without a fight. I would try to stop Nightmare, and give Celestia the opening to kill us, as we were one, and I could not inflict this terror on Equestria. As the day drew closer, I feared my demise, but never said anything to Nightmare, although she new I was planning something. And then, the day of the plan, as she called it, was here. I was too jumpy, I couldn't do it. She new is was planning something, and prayed on my doubt. She walked to me, not in life, but in the mind we now shared, and requested my plan. I refused to tell her, but this was her turf. The world was spinning. She did horrible things, brought out the thing I feared most, me... I couldn't let her do this! All of these years, living with this monster feeding my emotions, hurting my family through me, and I let her... I was such a fool. But, I was in this mind too, she wasn't the only one. She may have known my old plan, but I had a better one.
The fight had begun. I was trying to kill my sister! No, not me, her... I would not do this, Celestia knew I loved her, she would know it wasn't me. Right? She talked to Nightmare, calling her Luna, and fueling a new rage I felt, she didn't know it wasn't me! I was so angry, what I did that day wasn't right, perhaps I could have escaped, if I had just kept my head. Suddenly, I wasn't fighting Nightmare, I was Nightmare, Nightmare Moon, and I was powerful. I attacked Celestia, feeling not just my power, but her fear as well. I would be the one and only! Not princess, queen! They would cheer my name! They would love me! All I had to do was kill my sister. She was hurt for a while, but she had the elements, and she used them. Though it was over a thousand years ago, I still remember, when she sent me to the moon, Nightmare left my body, but I wasn't free, because the moon was just a bigger prison for me, and a sanctuary for her, and she knew it. She was too powerful, too strong, too much of me. And I was here, alone, with her.
