It has been now a week after the defeat of Nightmare Moon and life went back to normal in Ponyville. Well almost. A few were still scared about Antasma and wondered when he would attack. Celestia was told about him but was impressed that there was a being, which was able to overpower her once evil sister in a battle. She tried to locate him but he was good at hiding himself. She didn't gave up but it was geting harder for her to get along with her business as a princess and trying to locate a threat to her little ponies.
Meanwhile Antasma was spying on the Mane Six to find out any weaknesses but so far he only found out that all of them were crazy. That Pinkie Pie was crazy was something everyone already knew but Twilight was supposed to be the smart but she acted sometimes like an idiot. He remembered when she got two golden tickets but instead asking for more in the first place, she just let everyone in Town do things for her; even she didn't wanted them do these things; and asked for more when it already turned into a 'desaster'.
Taking a break from the spying, he noticed an Antasmunchie that held the spirit of an familiar evil alicorn. Even it can't be seen, she glared at him. "You will not get away with this bat." She hissed, her voice coming out of the Dark Orb. The Bat King only smirked before he replied, "I don't think so. I told vou that you could be of use und vhile vee are talking thee changes are taking their effect on you."
"What are you talking about, my King?" She asked before the shock came. "Wait what did I just say?"
"That's vut I mean. I put a spell on that Antasmunchie to change you und it slowly erases your vishes, your desires und maybe your memories und personality."
"W-what do you mean with that?" She asked with a bit fear.
"I mean that you vill become my servant. You vill think that you vere destinied to serve me, SCREEP!, und you vill listen to every of my commands...und don't think I mean commands vhere you vould do things that you vouldn't vant to do. I'm not that kind of bat."
Nightmare was horrified. The thought that someone would change her was scaring her but she didn't wanted to accept it. No. She is Nightmare Moon, the Queen and true ruler of Equestria! She would never be someponies servant. But she called him her King. It was just to confusing for her. "I will never be a servant or slave to somepony like you."
"Vee vill see. The Antasmunchie will give you your own body vhen your transformation is done. It vill look und be exact the same body you had vhen you used the body of this 'Luna'. Goodnight Nightmare Moon."
Nightmare fought against the changes after Antasma was gone. But she wasn't strong enough to beat them. Slowly her thoughts began to change to exactly what Antasma told her. She still tried to fight but the thought of serving her master was stronger. She closed her 'eyes' before she saw only darkness.
After hours, she woke up and found out that she was back in her old body that she had now only for herself. She didn't had her armor anymore but she didn't care. All she now cared about was serving her master and do everything he commands her to do. She saw her mirror image in the nearby window and for some reason, the thought to look good for him came into her mind. She went into her old room and brushes her mane. When she went out of it, Antasma came into the room and she instantly bowed. "Good morning my lord. What can I do for you?"
"Hm looks like the transformation vas a success. Good. Now I don't vant anything. You can go." He said.
"As you wish." She said but for some reason, she wanted to be close to him. She felt so safe being near him and she is happy to have him as her master. But she noticed that she stared at his chest for a few minutes. Antasma didn't said anything, he neither didn't notice her staring at him or he didn't care. She began to ponder these thoughts but then it hit her. She still knew Antasma changed her into that way but she didn't mind that. It was that he had by accident made her having a crush on him. 'But this isn't important right now. I need to be a good servant, that's what matters.' She thought to herself. She went back to her business and tried to guard the castle if an intruder gets there, even though it would only be the Mane Six.
Antasma then continued his spying with a bored exprission. This is going to be a loooooooooong day.
