"Make some friends?" Twilight almost shouted. "Nightmare Moon is going to come any moment, there's no time for friends!"
"Well, I think it was good advice. Really, Twilight, it's just an old pony's tale." Spike replied.
They had already checked on all the preparations for the Summer Sun Celebration, and now they were heading back to the Golden Oaks Library, where Twilight was staying. When they entered, it was strangely dark and quiet.
"SURPRISE!" The lights flashed on, and almost all the ponies in town popped out of their hiding places. Pinkie Pie was among them, a party hat upon her fluffy pink mane. Lavish party decorations were strewn around the room.
Twilight was very confused and surprised, but not in a good way.
~oOo~
"No!" Celestia shouted. "I won't let you!"
"Stop fidgeting, Celestia. You know you're making this worse for yourself." Sekhmet said. Ah, Celestia was bound to find out Sekhmet's plan. And she definitely didn't want to be a part of it.
There was a blinding flash, and Celestia was no longer Celestia.
She was a Nightmare.
~oOo~
"And now, Princess Celestia will raise the sun!" Mayor Mare announced. The curtains behind her opened, and, the crowd gasped. Because nopony was there.
"Oh, my beloved subjects. It's been so long since I saw your precious little sun-loving faces." Nightmare Moon crooned.
"What did you do with our princess?!?" A pony from the crowd shouted.
Nightmare Moon chuckled. "Why, am I not royal enough for you? Don't you know who I am?"
Nopony dared to answer her.
"Does my crown no longer count, now that I have been imprisoned for a thousand years? Did you not recall the legend? Did you not see the signs?"
Twilight Sparkle stepped forward. "I did, and I know who you are."
Nightmare Moon raised an eyebrow.
"You're the Mare in the Moon, Nightmare Moon!"
"Well well well, somepony who remembers me. Then you also know why I'm here." Nightmare Moon smirked.
"Ummm... You're here to..." Twilight started to sweat nervously. What was Nightmare Moon here to do?
Nightmare Moon laughed again. "Remember this day, little ponies, for it was your last. From this moment forth, the night shall last FOREVER!" Nightmare Moon laughed and laughed. All was going as planned.
The ponies all fled from the building. Then a slender, somewhat beautiful, but cruel mare trotted in. Her fiery mane whipped back and forth, casting long shadows along the walls.
"This wasn't the plan, Nightmare." Solar Flare said icily.
"What do you mean? There wasn't any plan, Flare. I just did what I thought needed to be done."
In an instant, Solar Flare was upon Nightmare Moon's throat. "You knew the plan! You always think you know best, but you don't!" She eased of of the black mare's neck, and regained her composure. "But... I know you. You're not one to act with such foolishness. You... Wanted this." Solar Flare laughed menacingly. "You double-crossed me. Used me. Just so you could get what you wanted. So, are you going to dispose of me? Are you?" She mocked.
"Of course I was using you, fool! You and I had different goals. You were an idiot to think we could work together." Nightmare Moon shook her head. "But what else can I expect from you?"
Solar Flare just laughed in response.
"What's so funny?" Nightmare demanded.
"It's just, I was using you as well! Oh, the irony. So, I guess it's your turn to be surprised." Solar Flare smiled in a way that was far from friendly. "So, you and I both are traitors. And we both know what happens to traitors."
Nightmare Moon scowled as she fly toward her sister, a deadly scythe in hand.
~oOo~
Luna was horrified as she saw herself... (Was it even her anymore?) She was fighting Celestia. Her sister. But she couldn't stop herself, and worse, part of her wanted to. They clashed and lunged. Celestia, or whoever she was now, was skilled at magic, but Luna was better at combat overall. But whoever had taken over Celestia was also very skilled in combat.
The two alicorns' horns lit up, collided, and created a blinding flash of light.
