~My Little Pony: The Dark Defender~
~Prologue~A bluish-purple pony...a alicorn with a flowing navy blue mane and tail, a necklace with a mark that matched her cutie mark, and a purple tiara was once again out on the balcony in the middle of the night. She was the master of the moon, represented by the crescent moon cutie mark on her flank. She was also the younger of two sisters. She was using her power to watch over Equestria. She has been doing this often recently because she was searching for somepony...somepony from long ago...somepony from before she became Nightmare Moon.
Little did she know that she herself was being watched as well. She was being watched by the older of the two siblings, a white alicorn with a pastel rainbow colored mane and tail that flowed like her sister's. She had a necklace that had a diamond making in it and a golden crown. She had a sun cutie mark on her flank. She was worried about her little sister. She seemed to be having trouble accepting the fact that it's been over 1,000 years. But the sun pony also understood why her little sister was having so much trouble adapting. After all, even she was having trouble letting go.
“You're looking for him again, aren't you, Luna?” the sun sibling asked as she walked up behind her.
“Big sister! I apologize if I have disturbed your slumber, Celestia,” Luna replied, “How did you know what I was doing?”
“I've been watching you for many months now,” Celestia admitted, “And I understand what you're going through. He was a good friend of mine as well...A little odd at times, but a good friend nonetheless. Of course he was more than just a 'good friend' to you, so I understand that it must be harder for you to accept. But the fact is that the accident happened before you even got your cutie mark.”
“I know,” Luna said as she managed to hold back her emotions for a few moments. But she couldn't hold it anymore and she broke down in tears. Celestia hugged her little sister in an attempt to help her feel better.
“It's almost time for me to raise the sun,” Celestia said as she wiped away a from her little sister's cheek, “Afterwords, you should go to bed and get some well deserved rest. Some sleep should do you some good.”
Luna nodded in agreement. After Luna lowered the moon and Celestia raised the sun, Luna went to her room and went to bed. She grabbed a box and opened it up. Inside, there was a dark red unicorn horn that was the size of a filly's horn. Then she fell asleep, exhausted from another night of her failed search.
“Sleep well, my sister,” Celestia said quietly, “Fate has a funny way of playing itself out. As for me, I've got a busy day today. Including introducing Twilight Sparkle to a friend of mine.”
In the shadow of a hill overlooking Canterlot was a black alicorn with a dark red mane and tail. His eyes were also dark red. His dark red horn had a crack where it appears to have broken once before. “She's getting ready for her return to this world,” the dark alicorn said in a dark voice.
