Twilight trotted through the large marble corridors of Canterlot Castle. It had been a while since she had last visited the large building and the city, and it felt nice to get a little time from Ponyville. She even wrote to her parents about her visit and promised to go and visit them as well. But that's not why she's here. No. Luna had invited the lavender unicorn for star gazing. And of course Twilight couldn't say no, especially with the pony who supposedly created them. With the help of the sun goddess, Twilight hopped on the first train out of town the next morning, arrived at Canterlot, and was given the same room she always got when she visited. Her old room in Canterlot. The tall bookshelves, big lush bed, and a large viewing window with a telescope set up near by for when she used to look into the night sky as a filly.

After getting settled in for the next few days, Twilight went out a trotted through the streets, stopped by her parents for a few hours, and spent some time with Celestia talking about a few of her latest friendship reports. After that she was left to do as she pleased for the next few hours until it was time for Luna to raise the moon and waken the stars to accompany the dull gray sphere that would watch the night sky. And for those few hours she had, she had gone to the dinning hall and grabbed a bite before heading to where she was going now.

Her hooves made a slight 'clop' as she neared her destination. She reached the decorated doors that had a gold lining on the edges along with a brown paint that beautifully matched. With a whiff of her magic, Twilight easily flung the doors open and stepped into the nicely lit Canterlot Library. Inside are rows upon rows of tall bookshelves, each stuffed with books of every color, subject, and thickness. New or old. A smile formed across Twilight's' lips as she quickly bounded into one of the many rows of shelves.

She didn't really have anything in particular in mind, but the thought of reading a book sounded good. Then again, reading always had a special place with her. Twilight made her way down the bottom section of the shelf in search of something that would interest her, but found noting, so she tried the next set. Again she scanned the books titles, and again found nothing. However, the lavender unicorn was determined to find something! Anything!

Twilight furiously scanned through rows and rows of shelves until she reached one where everything seemed uninteresting or she had already read it, but stopped when she came to one that seemed... out of place. A medium sized book with a pale, sand colored spine. Twilight grabbed the book with her magic and slid it from its spot, and took a look at it. The sand color covered the entire book, and its edges were torn and spotted with old age. The title immediately caught the unicorns attention. "Star Swirled the Bearded: Theoretical and failed spells." Twilight quietly read aloud to herself.

In a moment Twilight quickly sped off to one of the large circular wooden tables that sat in the center of the library and quickly opened the book. Twilight began to quietly read to herself now that she had found something that she hadn't read before. "In theory, a talent enhancement spell would be able to enhance a pony's special talent by three fold. After many attempts at trying to create such a spell, I finally came to the conclusion that a pony who has undergone the spell would be needed to cast the spell itself; or an alicorn would be needed to perform the spell for anypony who wishes. Even though I was unable to perform the spell, Celestia had deemed it too dangerous for anypony to use, and has therefore been banned and labeled 'dark magic'." Twilight paused for a moment to ponder what she just read. "Well that's odd. Why would she deem it dark magic?"

After another moment of contemplating, Twilight read on. "Another spell that I created is a spell that will teleport anypony into an parallel universe. In order to cast such a spell, an unicorn must focus all of his or her's attention and concentration on the spell. Any loss in the train of thought may prove disastrous for those who were being teleported. Celestia has deemed the spell safe for only the most powerful of unicorns, and alicorns alike. The spell is cast by fou..."

"Luna, I've told you already! It isn't there!" Twilight heard Celestia's panicked voice from down the hall.

"Tai, perhaps thou has miss placed the book. Surely it couldn't have just disappeared, could it?"

"Lulu, you don't understand the amount of spells that are in that book that nopony should find out about. Theoretical or not, some of those spells could cause the entire nation to go into a rampage should a unicorn powerful enough use them!" Twilight let out a small gasp at the explanation, realizing that she has the book the princesses were talking about. "I'm going to check the library, why don't you wait for Twilight and I'll fix this." After that the sound of hooves hitting against marble got closer and closer.

Twilight quickly closed the book and stuck it in a random spot before hiding behind one of the shelves, not wanting to be found reading the book. A moment later and the sun goddess marched through the door and took a quick glance around the library. With a short sigh, Celestia made her way into the large room and began to scan through the books just as Twilight had done. Twilight quietly sneaked around the shelves, avoiding the princesses gaze. After what seemed like forever, Celestia let out a frustrated sigh before exiting the room defeated.

Once Twilight confirmed that the princess was gone and she could safely take the book elsewhere. She sprinted to the books location and took it in her magic before bolting for her room to read in peace.

Luna and Twilight sat on the balcony of the Canterlot observatory, reading through star charts and changing the angle of the large telescope every now and then to take a look at a distant star or galaxy. Twilight turned to the lunar goddess and pondered about telling her about the book. "Luna?"

"Mhm?" Luna replied without looking at the lavender unicorn.

Twilight hesitated for a moment before continuing. "I heard you and Celestia talking about that book, and I... here." Twilight used her magic and lifted the book out of her saddlebag and Luna now watched with an ammused expression. "I didn't realize it was something Celestia wanted hidden until I heard you two talking, but I really wanted to read it, so I hid it so I could read it before this."

Luna smiled down and the mare as she went on and explained. "Twilight, I'm sure Tai would've let you borrow the book if you had just asked. You didn't try any of the spells, did you?" Twilight shook her head while keeping eye contact with the princess. "As long as you didn't, you should be fine. Guard, please retrieve Celestia for me. Tell her it's urgent." The guard salluted before rushing off to find the sun goddess. Luna turned to Twilight with another heartwarming smile. "I'm sure Tai is up at this time."

Twilight had a look of worry painted on her face while she looked around her as if looking for a way to escape. "Are you sure she wont get mad at me? I did hide the book from her."

"I think she will understand, Twilight." Luna replied before returning to the telescope and Twilight soon joined the lunar goddess.

As the two continued to discus about the different constellations and galaxies, a very grogy and aggitated Celestia marched into the observatory a few minutes later. "Lulu, what is so important that you needed to wake me up three hours before I raise the sun?" Celestia demanded as she came closer to the two.

Twilight froze where she was at the sound of an agitated sun goddess. "I believe Twilight here has something of yours." Luna replied, extending a wing in the mares direction.

Twilight turned to face Celestia and swallowed a lump that had formed in her throat before taking a shaky breath. "I'm sorry princess, I didn't mean to hide it from you. I saw it was written by Star Swirl the Bearded and I really wanted to read it! I didn't attempt any of the spells I swear!" Twilight explained as she bowed to the sun goddess in shame while at the same time levitating the book in front of her.

Celestia looked down at the lavender mare, a headache starting to form. It's too late at night to be dealing with this. Luna owes me after this. Celestia smiled at Twilight before speaking. "It's alright, Twilight, so long as you didn't try any. Now if you will excuse me, I'd like to get the last of the nights rest." With that Celestia took the book in her magic and trotted out the observatory doors.

Twilight got up from her bow before collecting her stuff in her saddlebag. "I should probably get some sleep too. Same time tomorrow?" Luna nodded to allow Twilight her leave.

Twilight quietly closed the door to her room and rushed to the large bed that had thick comforters and under that, soft silky sheets. The pillows were equally lush and comfortable. Twilight lifted one of the pillows with her magic and under it a single piece of paper. She quickly took the paper and made her way to the center of the circular room, and read over the paper a few times before tossing it.

Twilight's horn glowed and grew in intensity as she continued the spell. Not too long after she could feel the amount of energy being used and began to feel light headed but kept at the spell. A light breeze began to pick up in the room, and along with it her light headedness increased until she lost her concentration causing her spell to fizzle and back fired. Twilight was flung back into a wall, her head smacking against it with a loud 'crack' and her limp body fell to the floor. Everything went quiet.

Author's Note

Ah, this didn't take me very long to write. I'm pleased with the beginning of this and I hope to get a good chunk out of the next part.
