It was almost time for the celebration, and Twilight was still in the library; wondering what Celestia would hide, and why? Spike had woken up about fifteen minutes after Celestia left; and was occupying himself reading Stallion and Hobbes. Twilight gazed out the window, what an amazing view. She could see all of Ponyville. It was getting dark, so most of the ponies were heading in, but there were a few still out and about. Twilight was too high up to recognize any of them, they all looked like ants. One ant was running quite fast though. It was dashing right down Mane Street, then took a fast turn towards the Ponyville library.
"Is it looking for me?" Twilight thought. "I hope it's nothing too urgent..."
"What are you looking at?" Spike asked.
"Oh, somepony is at the library, probably looking for me." Twilight responded.
"I wonder what for...did you scare the little fillies again?" Spike laughed as he went back to his reading. Twilight was so distracted by her thoughts she hadn't noticed Princess Celestia walk in.
"Do you like the view?" She asked, as she shared a similar glance, although her eyes were pointed more towards the mountains than the library.
"It's wonderful" Twilight replied, not even showing how much Celestia had startled her.
"Rainbow Dash was a big hit at the stadium today...those rich snobs seem to get a kick out of those with complete disregard for the rules" Celestia giggled a bit, and sipped some tea. Twilight hadn't even noticed Celestia had brought anything with her.
"What are you doing back here? I thought you had some 'boring diplomatic work' to do." Twilight asked.
"I finished that just in time for the celebration." Twilight's heart skipped a beat.
"Did I miss it?" Twilight said, hiding her shock...not-so-well.
"Oh, no no no. The celebration won't start until I enter the room. They need me to give some speech or something before they start." For a princess, she really seemed informal. "I noticed you weren't in your seat, so I decided to stall, and get one of my comedians up on the stage... I hope he does better than the last guy." Celestia sipped some more tea. "I went off to find you here; I had assumed you got distracted by the view like I do. Sometimes I find myself gazing out across the world for hours, when it only feels like minutes have passed by." Celestia gave a quick smile. "'Tia! Tia! It's time to raise the sun! You're running late!'" Celestia tried her best Luna impersonation, unaware Luna had walked in just at that moment.
"Oh please, I do not sound like that sister." Luna said mischievously. "Are you finished yet? The comedian is running out of jokes."
"How can you tell?" Celestia asked.
"He started singing songs by Bruno Mares..." Luna said, hiding her head.
"Oh no..." Celestia said in agreement.
"Well, it's better than having Twilight dance" Spike said, and then was greeted with a quick shove to his side by Twilight Sparkle.
"Well, I suppose I should get to the point" Celestia said. "I want you to come into the ballroom with me. You are my most faithful student after all." Twilight agreed, and Spike put his book into Twilight's bag. The four of them (Twilight, Celestia, Luna, and Spike) went to the ballroom.

They arrived in the ballroom, and the alicorns took their seats. A guard had grabbed a chair for Twilight, and another for Spike. Celestia gave her welcoming speech, and all the guests began enjoying their Apple's and Apple-treats. Although, she still never mentioned what the celebration was for. Rarity did really well with the fancy-people. Pinkie Pie and Applejack remained in the kitchen...good call. Fluttershy and Rainbow Dash never showed up; they were probably still at the stadium. The royal guards brought in special food for the royalty; however they probably mistook Twilight and Spike for royalty, because they also got some. Well, they were sitting with the princesses, can't really blame them. It all looked so good. Twilight was about to take a bite into a delicious looking pie, when Spike poked her.
"What do you want Spike?" She said a bit frustrated... she really wanted that pie.
"Do you still have that book I gave you?" Spike asked.
"Yes..."
"Can you pull it out for me? I'm bored."
"Oh fine..." Twilight pulled the book out of her bag, and a paper with writing on it fell out.
"What's this?" Spike reached down and picked it up and tried to read it. But couldn't. So he just sat there quietly.
"Well? What does it say?" Twilight asked.
"Well... There's this weird symbol on it, then a backwards 'C' an 'N' and then a 'P'"
"What?"
"Just look for yourself"

ʞɔnp

"It's upside down Spike..." Twilight said as she flipped the paper around.
"Oh" Spike blushed a little, but being a purple dragon, hid it very well.
"See, it clearly says..." Twilight got quiet for a moment.
"Twilight?"

duck

"...duck" Twilight read quietly.
"Hm? I didn't quite catch that" Spike said, curious as to what the note really said.
"duck..? duck...? duck! DUCK!" Twilight grabbed Spike and crouched down, just as the sound of a loud explosion and broken glass filled the room. All the palace guards rushed to the Princess. But it was too late, a shadowy figure had already dashed threw the broken window, jumped over Twilight (still ducking,) and snatched Princess Celestia. Teleporting away.
"W-What... What just happened?" Luna asked, trying not go go into shock.
"Your sister has been kidnapped, and we've already got the guards mobilized. We are going to find her. In the mean time, you will need to fulfill her duties of raising the sun." One of the guards said. But by the look of his armor, he must have been the general.
"But I can't do that! I don't know her spell for that!"
"Then for the time being, we will be locked in eternal night until the Princess is returned." The general then turned to the guests. "Now all of you; do not worry. The princess will be returned. Just go home, the celebration has been postponed." The guests all started leaving.
"You would think our mighty Princess, the only one who can raise the sun, the only one fit to rule us, would put up a better fight than that...Even I could have done something" A random guest murmured under his breath as he walked by Twilight; not intending for anyone to hear. But Twilight heard it. It did seem a bit odd the Princess wouldn't put up a fight at all. Too odd...

Before Twilight could continue her possible theory, a group of masked figures--from the looks of it, they were all pegasus ponies--charged in through the main gate. The guests were all gone by now, the entire ballroom was in a wreck, broken glass was all over the place...
"What...the...buck?" one of the figures said. They all just stood there for a while, looking around. Suddenly the royal guards attacked, and quicker than a blink, the four pegasus burst into action. A few of the guards were knocked down, but nopony could have predicted what would happen next, another mysterious figure flew in from the broken window. It's horn started glowing--must be a unicorn--and suddenly the four figures were tied up, and hanging off of the chandelier. The figure turned it's head towards Twilight, there was something familiar with it's eyes...suddenly there was a bright flash, and the figure was gone. The royal guards, keeping the 'bad-guys' tied up, carefully unhooked them from the chandelier, and carried them out of the ballroom. Twilight was going to help clean up the glass, now that all this chaos was over, when Luna tapped her shoulder.
"Come with me" she said. "I have the feeling these four trouble-makers will know what's going on. Follow me"
Twilight followed the princess through the castle, and down some stairs. They arrived in a dungeon of sorts. Luna led Twilight down the hall, and pointed towards a locked cell. Inside were four pegasi; a white one, a black-ish purple one, a brown one, and a orange one. Twilight didn't recognize any of them. She was going to look at their cutie marks, but realized that may be a bit akwaed.
"Who are you?" Luna asked, with a bit of anger in her voice.
"Well," the white one spoke up, in a prideful, annoying, cocky voice. "We are none other than T.A.G, Together Against Government."
"But..." the brown pegasus began. "Didn't we agree on the Forces Against the Good?"
"Don't you remember? We changed our name because of what it spelled..." The orange one said, sighing a little.
"Nopony would tell me what it said!" the brown one interjected.
"Can't you read? Honestly, it amazes me how dumb you ar---"
"WHITE!!!! Orange is making fun of me again!" The brown one whined.
"Did not!" Orange said.
"Did too!" Brown said.
"Do I have to solve everything around here?"

The three of them started arguing, Luna and Twilight both looked at eachother...insanely confused. The blackish-purple one just sat in the corner, ignoring the squabble of the other ponies...for a while. Suddenly he burst out:
"WOULD YOU ALL JUST SHUT UP!?!?!"
It all got quiet. The three other pegasi were all staring at him.
"...woah. Did Nightmare just talk? He never talks..." Brown said, turning his head a little.
"He must be really mad now..." Orange said.
"We're so screwed..." White said.
Nightmare just sat back down in his corner, and continued ignoring everything and every one. Luna turned away, and ducked her head.

"Princess Luna?" Twilight whispered.
"I'm fine." Luna answered...obviously lying.
"What's wrong?"
"I said I'm fine...And I must be going. I need to do extensive research on the sun raising spell." Luna walked away, with a small tear streaming down her cheek. Twilight was curious as to what triggered such a response... but she was also curious as to what these trouble-makers know. She walked up to the cell and asked in a very direct way.
"Why are you here?" showing more anger than Luna had when she asked a question. Brown, Orange, and White were all going to say something, when Nightmare broke their words with his.
"We are here to capture your princess--and we would have gotten away with it too if it weren't for your stupid unicorn magic." Nightmare lifted his hoof and pointed it at her horn."
"It wasn't me!" Twilight said nervously. "It was somepony who flew threw the window!"
"Nonsense! I sensed your aura when we were attacked!"
"I was in the ballroom, maybe you miscalculated"
"I don't miscalculate" Nightmare was starting to sound agitated.
"You must have, for I was on the other side of the ballroom..." Twilight said; when suddenly, Nightmare's eyes lit up, and suddenly had his face pressed against the bars, just in front of Twilight's face. but...pegasus can't perform magic?
"You listen, and you listen good. You are underestimating my true power. The only thing keeping me from busting out of this cell and slaughtering you, Luna, and everyone in this castle is the fact that these bars are enchanted with some sort of spell-block."
"How were you captured so easily then? If you are such a powerful being?" Twilight thought she had an edge on him. It wouldn't make sense for someone as powerful as Nightmare claims to be, to get captured by one unicorn.
"You used some sort of spell-block on me. How was I supposed to do anything?" ...apparently he still thinks it was Twilight Sparkle. But rather than agitate him again, she just went with it. "I would be out of this cell by now too, if I could get some bucking concentration going... But it's impossible with these morons in this cell with me..."
"Why did you allow them to tag along?"
"You have much to learn Twilight Sparkle..." Nightmare took a few steps back, and now that he wasn't in Twilight's face she could get a better image of him...or it. Nightmare had what appeared to be the body of a pegasus pony, made of shadow. There was a slight invisibility element to it. From up close, Twilight could not see anything but it's eyes, but now that she could see all of him, she realized how dangerous it could be. His mane was long and flowing like the Princess' manes, but his body lacked substance. "But first, I may as well fill you in on why Luna left..I am the one who corrupted her"
"But--"
"As long as there is harmony in the world, there will always be discord. There must be evil to combat the good. There must always be yang to the yin. As the world gets better, it also gets worse. You cannot defeat all evil, for it will always return. With this spell-block here, I can't break out anytime soon. There is no further purpose to you staying here."
"Fine..."

Twilight turned around and began to leave. She was very confused, and she hoped Luna would be OK.
"Wait!" White called. "Where is Princess Celestia?"
"I don't know..." Twilight said. "But I'm going to find out."
