The Ruler of the Night;Equestria's True Queen

           Nightmare sulked in the back of Luna's mind. She was plotting ways to take over Luna's mind and body again. It would be easier, since Celestia would return soon and she's weak. Luna will be easy to corrupt when she's weak. "Don't even think about it Nightmare. I know what you are planning. You cannot take me over. I may be weak in power, but I am quite strong in will. I will not be as easy prey as you think," Luna said. Nightmare scoffed. Luna still underestimates the darker alicorn of herself. Does Luna not remember how much power she had as Nightmare Moon? Apparently not. Nightmare searched in Luna's memories, but finds no trace. I know just how to show her how much power she can have, Nightmare thought. Luna was sleeping so she could think freely. Nightmare had a secret ability, though. She may be trapped inside Luna's mind as a shadow, but she can still manifest herself as she once was. Nightmare decides to do that. Nightmare summons her power, temporarily stripping Luna of it, and flows through Luna's magic mane out into the chambers. Nightmare doesn't think it safe to manifest here, so she went out on the balcony into the moonlight. She used her magic to manifest into a body. When she was complete, she stretched her wings and popped her neck. Then, she hid in Luna's closet until morning, when Luna would take a dress from the closet for her birthday.

           Luna stretched and got up. She set the moon with ease, but felt a pull on the sun. Like it was telling her something. Luna looked at it, confused. She gasped. She looked all over the surface, but it was gone. Celestia must be free!! Luna jumped with joy. She ran to her closet to get a dress, because it was her birthday after all. When she got there, she stopped. Oh no.... Nightmare got free?! How did she escape my head?! Luna thought. She went into Celestia's old chambers instead and got a dress from there. Then she ran down the stairs and was beaming. The maids had never seen her this happy. Luna went to Spike and told him to take a note. "My dearest Lightning Shine, come to Canterlot at once. Celestia has escaped her imprisonment and must be defeated. Bring me the Elements. I must fight her alone. When you bring the Elements and I have them in safe hooves, you may go back to Ponyville to your friends. Do not argue, for it is not your battle. It is mine. Your teacher and mentor, Queen Luna" Spike read it over to Luna and she nodded. "Good. It sounds like I am truly worried. Thank you Spike. Now your reward," she said. Luna winked at him then used her magic to give him what he loved. A mustache!

           Nightmare was furious. Luna didn't go to her own closet! Nightmare had no choice but to return to Luna's mind. So she became a shadow again and flowed through the castle. She found Luna by herself reading. As Nightmare was getting ready to head in, Luna turned and spoke. "Nightmare you are not allowed in my mind any longer. Celestia has returned and she and I will destroy you once and for all. Is my threat to you clear?" Nightmare gulped. She feared Celestia more than she hated her. Nightmare manifested and frowned. "I thought you wanted power? I can give you power. I can give you anything. I've given you-" she started. But Luna was prepared for Nightmare's snake tongue. Luna lashed out on Nightmare, pinning her against the wall with her wing. "You gave me nothing. You took my sister, you took my pride, and you took my joy of being home. I had joy before I knew you were still there, and I've known since a year after she was freed," Nightmare was shocked. This wasn't Luna. This was Celestia!! Celestia used her magic to shed her disguise. "A trick I absorbed from Chrysalis. Have you anything to say before Luna and I destroy you?" Nightmare couldn't breathe. She shook her head. Celestia smirked. Then she used her magic to take the Elements from the table. Loyalty, Kindness, and Honesty. Luna came from the shadows with Generosity, Laughter, and Magic. Together they created a force so great, nothing could stop them. Except one thing... Betrayal.
