Magic Mirror

Twilight walked into the thrown room of the her mentor and princess. She looked at princess Celestia, who seemed nervous.

"What's wrong, princess?" she asked worriedly. Celestia sighed. She slowly walked towards Twilight, quietly. With every step, she regretted having to do this to her faithful student.

"Twilight, I have an..... assignment for you. It will not be easy, but I am confident you can do it..." she said. Celestia's star student looked up at her, and she knew that Twilight would do anything she asked of her, no matter what the cost. At least, as long as her friends were okay.

The assignment is for you to go into another world. I know you are not familiar with this, but you have the power of friendship to aid your journey. The world is one of Luna's old favorites, and she used to venture there years ago, before Nightmare Moon. But, now that Nightmare Moon existed in our world, it exists in the other, too. In the other world, Nightmare Moon rules over Equestria in eternal night. The Elements of Harmony are lost, and the evil of the world grows stronger. It threatens to seep through the cracks and take over this world. I need you to go in and stop it." she finished explaining.

Twilight was more confused than she ever had been in her life, but she had one question on her mind.

"How do I get there?" she asked. "Its some magic spell or a secret door or something, right?" she asked.

Celestia nodded. " Actually, its a mirror. A magic mirror. In it, it holds the reflection of your world, the way it isn't and could never be. When the wars in Equestria raged against other nations, the mirror would be at peace, and it tended to stay that way. Luna would always use it to escape the evils of our world, because there, she could be happy and wouldn't have to fight. When Discord took over and we fought him, she would go into the mirror. In that world, he didn't destroy harmony, only annoyed it. Everyone was happy. Even Chrysalis and Sombra weren't evil. Luna spent most of her time there, but then she became Nightmare Moon, the evil of her was so powerful that Luna's love for the mirror was corrupt. The Luna of that world was 10 times as bad. She killed that world's Celestia. She killed everypony who disobeyed her. When I sent Nightmare to the moon, the other world's Nightmare moon grew more powerful. She made sure that there could be no Elements of Harmony to stop her, and that meant killing me, the original Element bearer. You and your friends never met, and therefore could never stop her. I need you to fix that world." she said, sadly.

Twilight was sure this mirror was the most dangerous, evil, magical thing owned by Princess Luna. Speaking of Luna, where was she?

"Um... Princess, where is Luna? Shouldn't she be helping you explain? It is her mirror after all." Twilight wondered aloud.

"I am over here Twilight." spoke Luna. Suddenly, Luna appeared out of no where. She had been using an invisibility spell to listen. "I wanted to be sure you didn't scream or run away from the thought of having to go in there. No worries, though. I am going with you." she announced. Celestia gasped.

"You are not going in there Luna. I will not have you going to that world. Twilight is perfectly capable of doing it on her own." she commanded. Luna sighed.

"Sister, you and I both know Twilight is still young, and she has only just become a princess. I know that world, and I know what it can do to somepony. I am going with her." Luna insisted. And she was right. Twilight was too young to be able to do it on her own. Luna has more experience with this world than anypony else. Plus, she knows how Nightmare moon thinks.

Celestia couldn't deny that her little sister had a good point. Twilight would need somepony to guide her. Luna was their best bet.

"I guess I can't stop you. Just be careful then." Celestia said reluctantly. She didn't want Luna or Twilight to go, but she had no choice. No other pony can do it, not even herself. She didn't know anything about it other than what Luna has told her, but she would never understand Luna's love for it.

Princess Luna led Twilight and Celestia to the room where the Mirror is kept. No pony can go in without her permission, not even Celestia. Only Luna can open the lock. She closed her eyes and focused on unlocking the door, but it took some effort. She hadn't gone into the room since she became Nightmare Moon. The spell wasn't difficult, but only she could do it. Finally, the lock gave in and the door opened. Inside was a giant cavernous space filled with nothing but the mirror. The walls were made of stone and crystals. The floor was shinning and the entire room was beautiful. Luna was all too familiar with the room, and took little notice to its beauty. All she was focused on was the mirror that lay in the middle of the floor. It had a sheet covering the glass. And she clearly remembered why.

Twilight approached the mirror with excitement and fear. She wanted to get this over with, but at the same time, she wanted to see what was in that world, and where she was. Knowing herself, she was probably working out a way to defeat Nightmare Moon. She grabbed onto the sheet and pulled.

"Twilight, wai-" Luna was too late to warn Twilight. The reflection in the mirror was one of Twilight Sparkle, but she was sad and broken looking. She wasn't an alicorn, nor was she powerful. She looked as though she never seen anything better than a pile of dirty hay, and to her, that was a highlight. The alicorn Twilight cringed at the image of herself. It was depressing and worthless. Luna walked behind her. As she did, the image of Nightmare Moon showed up on the mirror. As Luna placed her hoof on Twilight's shoulder, the mirror was Nightmare Moon striking Twilight and beating her down, laughing at the broken mare. Celestia would have comforted Twilight, but she was afraid of what she would see. In the other world she was dead. Her image would be a skeleton or a corpse, rotting.

Twilight took and deep breath. "I'm ready." she said. Luna nodded and slowly, she began to cast the spell. The glass of the mirror turned to a liquid and spilled down from the sliver and black frame. Inside was darkness and smoke. Twilight slowly walked into it, unknowing of what was on the other side. Luna followed, but Celestia spoke first.

"Be safe, sister. I love you." she whispered.

"I love you too, Tia." said Luna, smiling sadly. With that, she galloped into the mirror after Twilight, as the liquid mirror turned solid again, setting itself into the frame.
