"Twilight. Twilight. Twilight!"

"Mmm."

"TWILIGHT!!"

"AAH! I'm awake! I'm awake!!" Twilight whipped her around. "Rainbow?"

"I thought you wanted to go to Ponyville, egghead." Rainbow smirked as she put on her bracers and belt.

~~~~~~

"Hey Rarity!"

The white unicorn turned around to the sound of the voice.

"Hello Applejack. Are you heading to the library?"

"Yeah. So is Pinkie an Flutters. Ah don't know about Rainbow though. Ah haven't seen her in ages." The earth pony said as she trotted to her friend.

"Me neither. I do hope she is okay."

"Hiya Rarity! Hiya AJ!!"

"Howdy Pinkie."

"Are you going to the library? Of course you! Do you know how I know? I don't know! But I bet it's something important!" She giggled.

"Umm....hello girls."

"Hello Fluttershy. Off to the library too?"

The shy pegasus nodded.

"Ah wonder what Twilight wants."

"Fluttershy, dear, do you know where Rainbow is?"

"No. She dropped off Tank a few days ago at mine. She said that she was too busy to look after him. I'm sorry that I couldn't help you."

"That's okay Flutters!!" Pinkie brought the butterscotch pegasus into a spine cracking hug.

"Err...Pinkie. Can you let me go? That is...if you don't mind."

~~~~~~

*Knock. Knock. Knock.*

"It's open!" Somepony-or some dragon-shouted from inside.

The girls cautiously let themselves in.

"Hi girls."

"Hey Spike. Is Twi here?"

"TWILIGHT!! THEY'RE HERE!!" The baby dragon yelled from the bottom of the stairs.

"I'm coming. I'm coming." Hoof steps filled the library. A lavender alicorn trotted down the stairs.

"Good day girls."

"Hi Twilight."

"Please, sit down. "

The four ponies sat on the cushions in front of them. Twilight too, sat on a cushion.

"Spike. Here are some bits. Go to Sugarcube and treat yourself. " She hovered a small bag over to her assistant.

"Oh great!! Thanks Twi! Bye girls!!" He waved as he ran out the library.

Twilight waved back to him, before turning to the others.

"I guess you are wondering why you are all here."

~~~~~~

"This is so great! I'm gonna get me some ruby cakes!"

"Hey Spike."

"Oh hey, Applebloom."

"Whatcha doing?" Scootaloo asked.

"Twilight gave me a bag of bits to go to Sugarcube Corner."

"Why?" Sweetiebelle squeaked.

"I...I dunno." He shrugged as he skipped off.

"Something is mighty suspicious here."

"Ah agree with Scoots. Let's go an see wha Twi is up to."

"Wait!" The unicorn filly waved her arms in front of her friends. "That's spying. She could be doing something private."

"Come on Sweetie. We could get our cutiemarks in spying."

"I-I guess...that would be a pretty good cutiemark. Okay."

~~~~~~

"Ya bet. Wha's goin on?"

"Yeah! And where's Dashie?"

"And what happened to your leg and wing?"

"Calm down girls. We have something to tell you."

"We?"

"Yes, Rarity. We."

~~~~~~

"Can ya see them Scoots?"

"Yes! But Rainbow Dash ain't there." The orange filly balanced on the very narrow windowsill.

"We're coming up."

~~~~~~

"You are probably wondering where Rainbow Dash is as well."

"Probably napping on a cloud. You know how tired she gets. Especially around this time of day." Rarity scoffed.

"No Rarity. I ain't napping on any cloud."

"Rainbow? Darling, where are you? I can't see you." The unicorn squinted as she searched the library.

"Right here." She stepped forward, revealing herself to her friends.

~~~~~~

"Woah! Look at Rainbow!"

"Ssshh!"

"Sorry." The pegasus filly whispered.

"Why is she wearing that?"

"It looks like a cloak."

"Yeah, but why is she wearing it?"

~~~~~~

"Rainbow, wha are ya wearing?"

"Oh! Oh! I know! She's wearing it because it's 'looking creepy day'! Or is it-mmm! Mmmm!" A set of zips formed on the pink pony's lips. Sealing the black hole of endless dribble and noise.

"Rainbow! Dear! This is magnifique! The way it flows with your body! And the way the red and gold blends with it!" Rarity gazed at her cloak. But as she lifted part of it, she saw a small dagger. Rarity's eyes widened as she stumbled back.

"R-R-R-Rainbow...d-dear. You have...a knife." She stuttered.

"Girls, I need to tell you something. Something important. The reason why I have the dagger and other weapons, is because...I am an assassin."

~~~~~~

"An assassin?"

"Ssshh!"

"She's...an assassin?"

"Isn' tha where they kill ponies."

"Eeep!"

~~~~~~

"What?"

"This is a joke...righ'?" Applejack looked towards Twilight, who in return shook her head.

"It's true. But don't be scared. She won't hurt you."

"I won't. I can't kill innocents. I won't kill innocents. I won't hurt you."

Fluttershy stepped up, and walked towards the other pegasus. She then looked into Rainbow's rose hue eyes, before hugging her.

"I believe you, Rainbow." She hushed.

"Fluttershy!"

"No Applejack! If it weren't for Rainbow, I would be dead."

"What do you mean?"

"She has been protecting me since I came to Ponyville. She saved me last night." Twilight trotted over to Rainbow.

"How?"

"Last night, there was a break in. A pony tried to kill Twilight. He only injured her. I killed him before he stabbed her again."

Applejack, Rarity and and Pinkie stared at Twilight's bandages.

"Is tha why ya leg an wing are wrapped up?" The orange pony pointed at Twilight's leg.

"The leg, yes. The wing, no."

"She fell down the stairs. But she used that as an excuse. She actually snapped her wing on purpose to find out what Celestia was doing."

Twilight sheepishly smiled. "Wait! How do you know that?"

"Like I said Twilight. I have heightened senses. I could hear you whining and the bone snapping."

~~~~~~

"That is so awesome!"

"I don't think we should have come here." Sweetiebelle sighed.

"Yeah. You say that Sweetie. But this is the best thing-woah!" Scootaloo tilted backwards, waving her forelegs in the air, before falling.

"Scoots!" The two fillies whispered loudly, watching their friend fall.

Scootaloo closed her eyes. Waiting for the flood of pain to come. Nothing. Surely they weren't that high. She cracked one eye open. There she saw the scowling face of her idol. She grinned as she leapt up.

"Thank you Rainbow!"

"How much did you three hear?" She asked with a tone of anger in her voice.

"Errr...."

"Lots." Applebloom admitted from above.

~~~~~~

"Eavesdropping is a very serious business. It's very bad." Rarity glared at the three fillies.

While the two elder siblings argued with the fillies, Rainbow Dash was sitting alone. By the window. Muttering.

"Innocentum tueri non materia quod. Innocentium nesciat, aut ad vitae leo. Per eos cognoscens, dissolvitis pars scriptor Symbolum prosmise. Viribus tueri potes ultra conferre. Omnes sumptus ad tuendos eos."

"Rainbow? Are you okay?" Fluttershy asked as she shuffled closer to her distressed friend.

"Mmmm! Mmmmm mmm mmmmm!" Pinkie tried to say.

"I'm fine." The assassin croaked.

"What are you saying?"

"It's latin." Twilight stated as she hovered a book over. "Buuut...I cannot translate what you had just said." She flipped the pages of the book.

"I cannot perform my full duties. Now that more of you know, you are more at risk."

The three fillies warily walked over to the four mares.

"We're sorry for syping on you." Sweetie admitted.

"We knew that it was wrong." Applebloom hung her head in shame.

"Yeah. I'm sorry too, Rainbow Dash. But it so cool that you are an assassin!" Scootaloo cheered. "It must be so awesome! Scary but awesome!"

The pegasus shook her head.

"Twilight! Please! You must erase their memories!" Rainbow begged.

"I'm sorry. Even if I could, it would be too dangerous."

"But we've got to do something! They are too young!" Rainbow raised her voice as she shakily stood up. "I can't....I-I..urgh!" She huffed.

"Rainbow. Calm down."

"I can't. This is too much." She sighed as she slumped to the floor.

"Rainbow, dear, when was the last you slept. You look terrible."

"Last month. I tried to sleep last night, but I couldn't. I couldn't give up my guard on Twilight. Even if Celestia did say she would stay awake, I couldn't still sleep."

"When was tha last time ya ate? Ya look really thin."

"I...don't remember. Ages ago." As if on cue, Rainbow's stomache growled. She looked up at the girls. "I'm fine."

"Rainbow Dash. Please. You've got to rest."

"Yes. I agree with Fluttershy. We understand that you must protect Twilight and everypony else, but you must eat and rest."

"I can't. You know I can't. The Creed is falling. The less there are of us, the less protected everypony is."

Twilight sat next to Rainbow.

"Please Rainbow. You are weak."

"I ain't. I'm fine." She snapped.

"Rainbow, I saw you collapse in front of Celestia the other day. You cannot go on like this. Please. Just sleep for an hour or so, and I could make you some lunch. It's the least I could do after last night."

"I could. A sleep does sound nice." Rainbow yawned as she lowered her head onto the pillow.

"Yes darling. And I could fix up your cloak. And that belt. As lovely as it is. It's in tatters." Rarity said as she took off Rainbow's cloak and belt. She stared at the dagger that was held in the tan belt. Engraved on the handle, among the swirls and spirals, were two names, Lightning Blitz and Sunset Breeze.

"My parents. They were good ponies. And I carry their final wish."

"And tha is?"

"To protect all of those I love." She smiled before closing her eyes.

"Mmmmm! Mmmmm!" Pinkie muffled.

"Ssshhh!"

"Mmm mm mmm mmm!" She pointed to her mouth, which was still zipped.

"Oh! Sorry." Twilight giggled as her horn lit up.

As soon as the zip disappeared, Pinkie gasped.

"Ssshh!"

"Come on girls. We are going to be Cutiemark Crusader Assassins!"

"Now, hold it righ' there. Ah tink tha' ya shall stay here. Ah don't tink it would be safe with ya runnin' around sayin Rainbow is an assassin."

"You mean..."

"We've got to stay..."

"In the library?!"

The mares nodded.

"Darn!" The fillies hissed.

"Well, at least you have lots of books to read."

The Crusaders groaned, and the girls giggled quietly.

Author's Notes:

Innocentum tueri non materia quod. Innocentium nesciat, aut ad vitae leo. Per eos cognoscens, dissolvitis pars scriptor Symbolum prosmise. Viribus tueri potes ultra conferre. Omnes sumptus ad tuendos eos.--Protect the innocents no matter what. The innocents must not know, or more lives are at risk. By them knowing, you have broken part of the Creed's prosmise. You can no longer protect them with all your might. Protect them at all cost.

I just typed it onto Google Translater. Okay. OKAY?!
