In Canterlot, the mane 6 found themselves standing near the Canterlot library, where the Star Swirl the Breaded archives were at.

" There's the library. Let's go." Twilight instructed, but Rainbow Dash stopped her.

" Wait. What about that guard?" She said, pointing at the guard standing in front of the doors.

" I thought this was a public library." Applejack added.

" It is, but this part of it, where the archives are, is the most secure."

" So how do we get in?" Fluttershy asked.

" I'm sure Princess Celestia told him that we were on our way and will let us through. So let's go."

The ponies trotted up the stairs to meet the guard. The guard instantly recognised Twilight.

" Princess Twilight Sparkle!" He said, bowing down to her.

Twilight smiled uncomfortably.

" Princess Celestia told me that you would be coming." He told her.

Twilight got rid of her embarrassment and got serious.

" Yes. My friends and I need to access someplace very important. It's an emergency." She said, showing the guard the keys.

He then turned to her friends, who were waiting patiently. Then turned back to Twilight.

" Of course."

He stepped aside and the ponies went in. Inside, the room was surrounded by shelf's of not only books, but scrolls as well, and in the middle of it all, a giant hourglass. It gave off an odd, mysterious vibe.

" Well this is...different." Applejack commented.

" Not really. It's just like any other library; except that it has powerful, creepy, unbelievable spells and super magical books in it." Pinkie informed as she looked through one of the selfs.

" We're not here to browse. We have to get to the back of the archives." Twilight replied.

" Lead the way!" Rainbow Dash said.

The ponies ran past the selves and to the very back of the archives. Finally, the door appeared and they all stopped in their tracks. Gazing at it, the door was made of solid gold and depicted images of Princess Celestial and Princess Luna with tiny jewels surrounding the pair.

" Well I do say, this is one of the most beautiful doors I've ever seen!" Rarity raved as she stared at it with a big smile.

" Yeah, but where's the door handle?" Rainbow Dash asked.

Without answering, Twilight took out the keys, which then began to float on their own, startling everyone. The keys glew a very bright yellow and it zapped at the door, which created a keyhole. The keys returned back to Twilight as they all looked at the door in amazement.

" Wow..." Fluttershy let out.

Taking the keys, Twilight opened the door and the ponies proceeded in. Looking around, the room had a high ceiling with no windows and it was covered with books and scrolls. Twilight had never seen so many books in one place. Her eyes shined, a big grin on her face as she gazed around.

" Words can't describe how wonderful this place is. I think I'm gonna faint." She said, forgetting that her friends were there as she leaned up against Applejack.

" Okay, get a hold of yourself, . We have a town to save." Applejack jokingly told her as she playfully nudged Twilight off of her.

" Oh, right." Twilight said, embarrassed.

She turned to her friends.

" Okay girls, start searching." She ordered.

" But where do we start?" Fluttershy asked.

" Start at the bottom then work your way to the top. Everypony got it?"

They all nodded and began to ravage through the books, hoping to find an answer to their problems.

" Golly, are these spells ever complicated." Applejack said as she turned the pages of the book in front of her.

" Yeah, but these spells are awesome! How to turn invisible! How to speak languages of different creatures! Turning grass into sweets!" Rainbow Dash replied excitedly as she flipped through her book.

" I like that one!" Pinkie said smiling.

" I like the one about learning languages of different creatures." Fluttershy added.

" Girls. As fascinating as all that sounds, we have a crisis on our hoods and need to find something that will actually help us. Twilight's counting on us." Rarity informed them before they all went back to searching.

Levitating books in front of her, Twilight examined every book that could be of importance to them. Then, she saw a book that caught her eye.

" This is the one!" She happily said, dropping all the remaining books that were levitating in the air as she brought the book to her.

Her friends joined her and they all studied the cover of the book. The title read "Dark spirits, magic, foes, and how to defeat them", written on a black cover in eerie purple text and illustrations of not only monstrous creatures, but horrifying ponies as well. One of them being Discord.

" Why is Discord on there?!" Fluttershy let out, horrified to see one of her best friends on such a creepy looking book.

" This must have been written before or after Celestia and Luna defeated him." Twilight replied.

Fluttershy was worried. Rarity put her hoof around her.

" Nothing to worry about, dear."

Fluttershy smiled at her as her worrisome attitude vanished.

" One of these has got to work." Twilight mumbled as opened the book and flipped through the pages.

While searching, she stumbled across an interesting page. Turning to it, the ponies saw a beautiful picture of a crown.

" Cool crown! But how is that supposed to help us?" Rainbow Dash questioned.

" it's even more beautiful than the door!" Rarity exclaimed, trying not to flip out.

" It's not to be fooled with." Twilight spoke seriously as she read the information to them.

" This crown was used to fend off powerful evil. Even more powerful than alicorn magic. In fact, it was only used for the most dire and dangerous emergencies."

" Can it help us?" Applejack asked.

Twilight looked over and then smiled once finished.

" Yes!" She happily confirmed, relieving her friends.

" But there's a catch."

" What?" Said Pinkie.

" The crown requires eleven jewels to power it." Twilight explained.

Rarity huffed sarcastically.

" Is that all? Darling, I can just use my spell to track some down and scoop them up."

" We can't. Says here that the jewels must be obtained by a princess." Twilight said.

" A princess?" Rarity replied, confused.

" That's what the book says."

" Soooo..." Pinkie said, getting close to Twilight.

" What?" Twilight asked, her eyebrow crooked.

" Cough it up!" Rainbow Dash demanded.

" I don't have any!"

A large shadow suddenly cast over them and filled the room.

" Why is it dark in here all of a sudden?" Fluttershy whimpered.

" I'm not sure." Twilight said, feeling strange and suspiciously looked around the room.

"I'll go check it out." Rainbow Dash volunteered.

She flew out of the room and looked through the library windows. Outside, she became frightened when she saw a big black and red swarm of creatures in the sky.

" What do you see, Rainbow?" Applejack called.

Rainbow Dash rushed in with panic on her face.

" We have to get back to Ponyville, now!" She exclaimed, scaring the ponies.

Taking the book, Twilight and her friends rushed out of the room, through the library, and out to outside. In the sky, they saw the creatures. They were changelings. Only, they were different.

" Those horrid creatures are heading to Ponyville!" Rarity proclaimed.

" Apple Bloom!" Applejack shouted, very worried.

" Same as before, huddle around me!" Twilight told her friends.

Together, she zapped them all back to Ponyville, unknowingly of what danger they were about to face.
