Author's Note

Hello, everyone! I'm back with another story, finally! Now, I don't know whether or not I'm back for good. All I know is I'm feeling pumped right now, so I decided to write this. It's only the first chapter and I don't know if it's gonna be good, but I'm gonna try. Like I said this is an AU and not everything matches between both stories so don't hurt me. Let me know what you think and I'll decide if this story continues! I have another in mind as well!

Ch.1- Initiation

It all started with that letter. Twilight could remember it as if it were yesterday.

"Dear Twilight Sparkle. Due to your astounding display of your magical prowess at the exam yesterday, I would like to extend to you an invitation to become my personal student. I believe that studying under me will give you a more in depth, focused look into just how vast your abilities are and can be. Of course, this does come with a bit more of a workload, but I believe you can handle it. And in the event you can't, well, I'll be there to give you a push should you need it. If you decide to accept my offer, I would be very grateful. But do not feel pressured to accept right away and give it the proper thought. Thank you"

Your teacher,

Princess Celestia.

Twilight could still remember how excited she was to receive that letter. She had begged her parents to let her go, and to her surprise, they said yes. In fact, they were proud of her, cheering her on as she walked up to the huge double doors that signaled the entrance to the famous boarding school.

She had been too excited to sleep the previous night, and had stayed up preparing for anything the princess might ask of her. She had her books, quills, paper, ink and note cards just in case. Lucky for her she was used to all-nighters.

Those days had been hard, but worth it, and she had learned so much over the years, that she couldn't imagine going back. Especially not with how much Princess Celestia trusted her. She may have been her mentor, but she was like a second mother to Twilight. And she trusted her completely

But now that she stood in front of the massive double doors the made up the entrance to the Princess' office, she felt more nervous than she ever had in her life. She gulped, tugged at the collar of her shirt, and stepped forward, knocking.

"Come in." Came the voice of the mare she had become so familiar with. A voice that now sounded more foreign to her than it ever had before.

Whether it was because she was on the other side of the door, or because Twilight was too nervous to fully recognize the voice of the woman who had practically raised her alongside her parents, she didn't know.

Whatever it was, she pushed open the doors and came in slowly, the sight of Celestia in all her glory coming into view like the unveiling of a priceless painting. For a moment, Twilight stood transfixed, and then she heard her name.

"Twilight? Twilight, I said, are you ready?" Celestia's voice called, causing Twilight to snap from her revelry.

"I'm sorry, ready for what, Princess?"

"Why, your initiation of course!"

Twilight's mind wandered as Celestia lead her through the halls and into some kind of room at the back.

"Where are we going, Princess?"

Before Twilight could ask any more questions, Celestia had conjured a key with her magic and used it to open a hidden door in the floor of the classroom. She gestured for Twilight to follow her down, which she did with a small hint of hesitation, which was quickly drowned out by her trust in the wise alicorn.

But once she was down in what had to be the basement, the questions forced there way back into her mind and she had no choice but to make them known.

"Um...Princess? What's going on?" Twilight asked, a hint of trepidation in her voice.

"You'll see Twilight. Just a little longer and we'll be there." Celestia said in a soothing tone of voice that seemed to ease Twilight's worries, though she could feel them still there, under the surface, waiting.

Twilight kept silent for the rest of the way there, which admittedly wasn't that long considering everything it took to get there. Soon they were coming upon what looked like an entrance into some kind of natural cavern, and what Twilight saw, nearly blew her away.

Books upon books, upon books scattered far and wide and organized immaculately into shelves by order of topic. The walls were covered with drawings of beasts the likes of which Twilight had never seen before and- was that a telescope?

Before Twilight could get too lost in everything that was going on around her, she heard a voice to her left say, "So, what do you think?"

She turned her head to see the Princess smiling down at her, her arms crossed with a knowing smile on her face. "Is it amazing or what?"

"It's wonderful Princess... but, why did you bring me down here?" Twilight asked, getting back on track with her questions.

"Because Twilight, you are now a member of the biggest monster hunting organization Equestria has ever seen." Celestia swept out a hand over all that lay before her.

"Welcome, to the Harmonizers."

"I'm sorry, the what now?" Twilight said in a flurry of rapid speech that came out of her mouth mostly without her own notice.

"I understand you must be shocked," Celestia said, a bright smile on her face. "What is a place like this doing under the school? What are the Harmonizers? Why are you hunting monsters?"

"Those are a few of my questions, yes," Twilight said, still caught off guard by everything that was going on.

"Well those are easy enough to answer. But first, let me ask you this," Celestia said as she ushered Twilight along through the cavern, showing her everything the place had to offer. "You understand that Ponyville gets attacked on an almost monthly if not weekly basis, correct?"

"Yes...?" Twilight answered, not quite seeing where this was going.

"And you understand that a threat to the safety of Equestria could strike at anytime, right?"

"Yes...?" Twilight was slowly beginning to paint a picture in her mind.

"Well, that's what the Harmonizers are for. We hunt monsters and eliminate threats to the safety of Equestria as a whole."

"Well, what about the Elements? What about you and Princess Luna? You're alicorns!"

"Being an Alicorn does not make you invulnerable, Twilight. And the Elements won't be around forever. What would happen if we were to become incapacitated somehow, or the Elements lost their powers?"

The thought of anything happening to Celestia was inconceivable to Twilight. She was the strongest pony in all of Equestria. There was no way she'd lose. Right?

Suddenly, Images of Celestia badly injured, or in a coma or worse flashed through her mind. Of Equestria in ruins, everyone either dead or a prisoner of some horrid tyrant. The thought made her blood run cold and her lip quiver in fear. She held herself tight as if she were freezing, taking deep breaths to calm herself.

"I...I don't know..."

Seeing Twilight like this, Celestia placed a hand on her shoulder, bringing her in close and letting her head rest on her chest. "It's okay, Twilight. I'm not going anywhere anytime soon. You don't have to worry." Celestia simply held her there, waiting until she felt better.

Meanwhile, Twilight was surprised. Celestia was holding her, comforting her just like she used to all those years ago. It brought back memories of her time as a young girl. Of the times when she'd cut her finger, stubbed her toe, or scraped her knee. When she'd failed a test, couldn't understand a question, or got a low grade. Celestia was there with her. She had always been there. There was no way she'd just up and disappear like that, would she? No, impossible. She had to be overreacting. She took a deep breath, stepped back and looked Celestia in the eyes.

"You feel better?" The Alicorn asked, a warm, loving smile on her face.

"Yeah...I do now..." Twilight said, smiling back.

"Good. I'm sorry I made you think of that, but you do understand what I mean now, don't you?"

"Yes, Princess!" Twilight said with a resolve she never knew she had.

"We need to be prepared for everything, which is why this library exists."

Twilight caught on to the word library like a spider to its prey. "This place is a library?"

"Yes, and a very extensive one at that, though not quite the one you're probably thinking of." Celestia said as she reached up and plucked a book off one of the shelves before handing it to Twilight, who eagerly opened it.

Celestia chuckled inwardly to herself as she watched Twilight pore over the book like a moth to an inky flame. Then she cleared her throat to gain her attention before continuing her explanation.

"This, is a monster library. It has information on every beast, every spirit, every creature to ever threaten Equestria since ancient times. And that book," Celestia said, pointing to the one in Twilight's hand, "is just the beginning."

"Wow..." Twilight stared at the book in her hands. This was just the start of a whole journey of information just waiting to be discovered. She took a moment to bask in the awe-inspiring majesty of all the wisdom that lay before her. As she looked around. She noticed something she hadn't seen before.

The very walls of the cave itself had been turned into shelves for books of all shapes, colors, and sizes, all organized perfectly and in order. The sheer amount of knowledge contained within these walls was enough to fill a second Canterlot Library. Twilight was sure she had died and gone to heaven until Celestia pulled her out of her revelry again.

"Ahem. Equis to Twilight Sparkle. Anybody home in there?"

Twilight could practically hear the smug grin on Celestia's face as she turned around. And sure enough a playful smirk lay there for all to see. twilight looked away in embarrassment.

"S-Sorry, Princess. Guess I got carried away..."

"The love of knowledge is not something to be ashamed of Twilight. Just make sure it doesn't take up too much of your time. Friends are important, too."

"But why would I need friends when I have you?" Twilight said, giving her a genuinely curious look.

"While that's very flattering to hear, Twilight, and while I do consider you my friend just as much as my student and even my own daughter, I am far older than you realize. I cannot be a proper friend to you because we have nothing in common. You need people your age, who can learn and grow with you. Which is why..."

"Which is Why...?" Twilight Parroted in a questioning tone.

"Which is why I got you a roommate!" Celestia swept her hand out again. Twilight noticed she seemed to enjoy doing that. But what Twilight saw next made her jaw go slack.

"Introducing... Sunset Shimmer!" Celestia called out.

Coming down a flight of stairs Twilight apparently hadn't noticed during her book filled revelry, was a rather tall woman with yellow skin and and black leather jacket. But that wasn't what caught Twilight's eye. No, what she noticed was her fiery red and yellow hair flowing down her back in elegant curls that framed a fair, unblemished face that held the most striking teal eyes Twilight had ever seen.

If she didn't know how love worked before. She was sure she did now.

"Oh, Come on, Princess. You're gonna make me blush." Sunset Shimmer said as she came down the steps and walked towards Twilight, holding out a hand.

"Hi there. My name's Sunset Shimmer, though, you already knew that. What's your name, if you, don't mind me asking of course."

For a brief moment, Twilight couldn't speak. She was too busy staring into those beautiful blue oceans the rest of the world called eyes. When she finally managed to stop herself from drowning, she blinked, accepted the hand and said,

"M-My name is Twilight Sparkle. It's V-very nice to meet you."

"It's nice to meet you, too, roomie. Come on, lemme show you the ropes around here."

Twilight caught onto that rather quickly and broke free of her romance-fueled trance. "Wait, she's not now like me?"

"'Fraid not, Twi. I'm a year ahead of you." Sunset said, a big grin on her face as she pointed to herself with pride.

Twilight looked to Celestia for confirmation and got a nod in return. "Sunset here is one year your senior. You'll be staying with her for the rest of the school year. She'll teach you how things work around here and get you all settled into your room."

"Our room? You mean, we're sharing a room?"

"Uh, yeah. What did you think we meant by roommate?"

"I only thought you meant we'd be sharing space in the cavern or something!" Twilight yelled, but then stopped herself. "Sorry, Princess."

"It is quite alright. I understand your trepidation. But trust me, this will be good for you both. In order to foster better relationships among teammates, we encourage them to share rooms with each other. To help them get along."

"I...I see..." Was all Twilight could say as she looked from Celestia to Sunset, Sunset to Celestia and back. Her heart was beating fast in her chest. Not only did she just meet the most attractive mare she thinks she'll ever see, but she also gets to room with her, from day one!

The pounding of her heart was so fast she could hear it in her ears. And it wasn't too long before her eyes rolled to the back of her head and she passed out on the floor, unconscious.
