The next day, Sun along with her sister, Screwball and her father, Discord just arrived at the school. She is wearing her magenta shirt with the shimmering sun on it, orange skirt with an yellow and purple stripe on one side, black leather jacket, and black boots with purple flames, and she's wearing her special necklace. Screwball is wearing her usual purple and pink like clothes and wearing her favorite propeller hat.

However, Discord and Screwball can tell that Sun is still feeling tired from that dream she just have. Sun has to tell them about the dream and it looks like Sun doesn't have much sleep last night.

As they get out of the car, Discord asks with concern, "Sun, are you sure you'll be alright for school?"

"Yeah sis. You don't look so good," Screwball replies.

Sun yawns a bit, shows a smile on her face and says, "I'll be fine dad. I just need some fresh air and something to take my mind off of that terrible nightmare."

"Okay, just let your sister and I know if you need anything," Discord says.

"Okay," Sun replies.

Screwball starts to run to the school to meet her friends and says, "See you later sis."

"Bye," Sun replies.

After saying goodbye to her had and sister, Sun walks over to the Canterlot High statue to meet Fluttershy and hopefully she can help her with this lack of sleep.

Sun yawns and says, "Man, I'm so tired. I hope Fluttershy can help take my mind off of that dream I just had."

Just then, Sun simply wobbles her way to the statue and is not watching where she's going. She ends up bumping into Fluttershy and they both fall to the ground and pink papers have fallen all over the place.

Fluttershy is able to sit up for a bit, but feels that someone is on her. Fluttershy looks to see that Sun is lying her head on her lap.

Fluttershy shakes Sun head as she says, "Sun."

Sun opens her eyes after feeling the movement of her body with a tired look and says, "Fluttershy."

Sun is able to sit down, but still feeling a bit tired. She rubs her eyes and is able to give herself a clear view of Fluttershy. Sun realizes that she accidently bump into her and drop the papers, which she knows are fliers on the ground.

"Sorry about that. I wasn't watching where I was going," Sun replies.

"That's okay. Are you okay?" Fluttershy answers.

Sun shakes her head bags under her eyes and says, "Not really. I had this crazy dream… more like a nightmare last night."

She then yawns in reply.

"Sound to me that you didn't get much sleep last night," Fluttershy replies.

"I didn't," Sun answers.

Just then, Angel comes out of Fluttershys backpack to see Sun. He turns to see Sun looking unhappy and tired. Angel jumps out of Fluttershy's backpack and onto Sun's right shoulder. He then starts to nuzzle sun's cheek with his head.

Sun smiles and says, "Thanks Angel. I feel much better now."

Fluttershy is happy that he is trying to cheer up her friend and are good friends. Sun gives Angel back to Fluttershy and then puts him back in her bag.

"So how are the flier passing going?" Sun asks.

"Not very well. It's nice that people are adopting animals from the shelter, but not so good not having more volunteers," Fluttershy answers sounding a bit disappointed.

Sun simply smiles and says, "Don't worry Fluttershy, you still have me, Tree Hugger, and Rarity helping out."

"That's good," Fluttershy happily replies.

Sun and Fluttershy look on the floor and realizes they forgot about the fliers that fallen to the floor.

Sun blushes a bit and says, "Maybe we should pick these up and head inside before class starts."

"I guess so, the warning bell will ring very soon," Fluttershy says, agreeing to the idea.

"Yeah. I don't need to be tar…" Sun replies.

But before she can say anything, something just hit Sun's head. The smack on her head feels really hard.

Sun rubs her head and screams, "Ow!"

"What was that?" Fluttershy asks with concern.

"I don't know. Something just hit my head," Sun answers while rubbing her head.

Fluttershy looks around to see what exactly hit Sun on the head. Just then, Fluttershy notice something on the ground and it's something very special.

Fluttershy surprisingly says, "Look!"

Sun looks to see where Fluttershy is showing and is surprised to see what it is. Sun can see a crown resting next to her feet. The crown is a light gold color with a magenta star shaped gem in the middle.

Sun picks up the crown and says, "It's a crown? What's it doing out here?"

"It's strange, the wasn't here a minute ago," Fluttershy adds.

"Well, it's there now," Sun says looking confused.

The two girls are confused about the crown since it just hit her on the head suddenly. They have no idea where the crown comes from. They don't even know what to do with it.

Sun turns to Fluttershy and asks, "What should we do with it?"

Fluttershy quickly has an idea and answers, "I know. Pinkie told me that the crown that was bought for the dance recently broke, so maybe we can use this crown for the Fall Formal."

"That a great idea Fluttershy. I can take it to Principal Celestia and you can meet me in music class," Sun replies, agreeing to the idea.

"Okay," Fluttershy says while nodding her head.

After they gathering the rest of the fliers, Fluttershy goes on a head to put the fliers in her locker and get to class while Sun is deep in thought about the crown. As she thinks about the crown whereabout, Sun starts to wonder about the crown's mysterious appearance and how it ends up hitting her on the head.

Before heading inside, Sun turns to the statue and says in her thoughts, "I wonder where this crown came from? There's no way that someone could throw it to me from behind. The statue is blocking someone's way."

Sun is wondering how it's possible for this to happen, but doesn't have a clue yet.

Sun says in her thoughts, "I better give this to Principal Celestia and Vice Principal Luna before class starts."

With that, Sun starts to head inside the building and give the crown to Principal Celestia and Vice Principal Luna. She think it will be a good idea to ask them about the crown, but leave out her mysterious encounter with it.

While Sun isn't looking, someone comes out of the base of the statue, which is actually a portal to a different world. The person is a girl and she has light peach skin, black hair with a pink streak on it, and light blue eyes. The girl is wearing a dark blue shirt with a shooting star falling from the sky on it, blue jeans, black shoes with white laces and a jacket.

The girl starts to look around for what she's hoping to find, but has no luck. She turns to see Sun taking the crown inside the building. The girls makes an angry look on her face because the crown has been in her grasps and lost it, but the main reason why she's mad is because Sun reminds her of someone she's despise the most. She decides to follow her and hopefully get the crown back.

In the hallways, close to Principal Celestia's office, Sun still have the crown in her hands and very curious about it. She looks at the gem of the crown and thinks it's very pretty. She then notice that the crown has the same gem like glow as her necklace. As she looks at the gem and the crown, Sun feels like trying it on, just for fun and see herself wearing it.

"It wouldn't hurt to put the crown just for fun," Sun says to herself.

Sun puts on the crown and it's a perfect fit. Just then, the gem on the crown begins to glow and it's creates a strange magical aura around Sun. Sun starts to to feel a strange force coming from the crown and is starting to been nervous about it.

Just then, Sun's eyes begins to glow white and feels something… magical coming from the crown. She starts to see that she knows this feeling before. As Sun is being surrounding by the magic, a vision comes into her mind. There are 6 ponies five of them looks exactly like her friends, but the sixth pony looks like the girl who she has met at Crystal Prep, but doesn't wear glasses. The crown shows her vision of the 6 ponies along with their adventures and friendship together.

When the magic stops, Sun eyes returns to normal and the crown stops glowing. As soon as Sun returns to reality, she starts to feel a funny feeling in her head. She takes off the crown to look at the gem again and feel that it's the cause of these visions.

"What… was… that?" Sun asks herself as she looks at the crown.

Sun has no idea what the crown just show to her and wonder if it's just her imagination or not. She starts to think it might be good idea to give it to Principal Celestia and talk to her friends about her strange vision. She then takes the crown to the principal's office and hope they can keep an eye on it and hope it won't cause trouble.

Back in the world of Equestria, Twilight Sparkle, the newly alicorn princess along with Spike and their friends are having a major problem at the Crystal Empire. Last night, Twilight's crown has been stolen by a unicorn mare and she escaped through a magical mirror.

The girls have no idea who the magic is and how they manage to let her escape. All they do know, Twilight's crown is lost through the mirror and somepony is after it.

Rainbow Dash panicky screams, "How on Equestria did we let this happen?!"

"I know, and we were in hot pursuit of that mare," Applejack replies.

Twilight sighs sadly and says, "Don't remind me."

Twilight is feeling very upset about losing her crown, her friends can tell. They tried to stop the thief, but the thief manages escape with the crown and element of magic. Twilight can still remember the night that her crown has been stolen from her.

Earlier in the night, Twilight and her friends, along with the princess are sleeping in their room. Suddenly, somepony wearing a black cloak manages to open the door and able to sneak past Twilight and Spike without waking them up. The pony uses her horn to levitate the crown and almost drop a lamp, but catches it in the nick of time. Seeing that the noise isn't waking them up, she puts the crown in her bag and replaced it with a fake replica.

Seeing that her plan is a success she starts to sneak way to the door and get away. But before she can, she accidentally trips over Spike's tail and hits the floor. The noise from her falls wakes up Spike really quickly Twilight ends up waking up as well, wonder what the noise. When Twilight turns face the door she can see that somepony has her crown in their bad.

She surprisingly screams, "My crown! She's got my crown!"

The mares hear Twilight screams and storms out, running away taking the crown with her.

Twilight starts to chase her and angrily screams, "Stop thief!"

She then starts to pursue the thief and Spike starts to come with her. The other girls wakes up after the hearing the noise and wonder what is going on. When they opens their door, they look to see Twilight running past their door. They can tell that something is wrong.

Their answer has been answer when Twilight screams, "She stolen my crown!"

The girls are shocked to hear what Twilight says and are determined to help out. Twilight tries to run after the thief, but she is fast. She then uses her magic to teleport herself to the thief, hoping to stop her in her track.

"Stop!" Twilight demands.

But then the thief uses her hort to teleport herself, but let the cloak falls on Twilight's face. The thief teleport herself behind Twilight seeing that she's been blinded. She then runs away hoping to escape. Twilight takes off the cloak seeing that the thief is running away goes after her.

The thief looks behind her and shock to see that Twilight and the others are getting close to her. Twilight tries to grab her by the tail but miss. The mare is seeing Twilight is getting close to her. At her last resort, Twilight pounces at the their and ends up rolling herself and the thief to another room.

When the crashes to the ground, the crown falls out of the thief's bag and bounces all over the room. The girls make it to the room to see the crown has falling straight through the mirror. Twilight and the girls gasp to see that her crown has fallen through the mirror while the thief makes an evil smile on her face. It's not how she hope to do, but manages to get the crown away from Twilight.

Twilight turns to the thief with a angry look and demands, "What did you do with my crown?!"

"Sorry it had to be this way…" The thief says.

She then teleports herself to the mirror and says, "Princess."

Then the thief follows the crown through the mirror as of hoping to get it back. The girls and Spike gasp to see the thief going through the mirror. Now they know that the crown is through the mirror, they need to find a way to get it back.

After the flashback, Twilight and the others are still in the room where the magical mirror is. They have no idea who that pony is or why would she take her crown. All they do know is that they need to get it back.

Applejack says, "I still can't figure out who that mare was."

"I never seen her before," Pinkie adds.

Then Spike suggests, "Think we should go tell Princess Celestia?"

"You're right Spike. She might have an idea who that pony was," Twilight replies, agreeing to the idea.

With that, the girls leaves the room to tell the princess what has happened. When they explain the pony stealing the crown and they both gone through the mirror, Princess Celestia has a pretty good idea who that pony is. The following morning, Twilight and her friend are in the throne room with the princess to explain about the pony.

"Falling Star, a old student from the School of Gifted Unicorns. She used to go to the school studying strong magic. However, during her time there, she developed jealousy and resentment towards Sunset Shimmer. It caused her to become cruel and dishonest." Princess Celestia explains.

Princess Celestia sighs and addly explains, "Sunset Shimmer tried to reason and become friends with her, but one day, Falling Star let her bitterness gone too far and I expelled her from the school and she decided to pursue her own path, one that has sadly led her to stealing your crown."

"And I supposed she blames Sunset Shimmer for the troubles she caused," Rainbow suspects with annoyance.

"I'm afraid she does," Princess Celestia sadly answers.

The girls are kind of surprised that Sunset has a very bitter rival and she blames her for being expelled. However there is something that's been bothering the girls since the event of last nigh.

Rarity asks with concern, "But what does she want with Twilight's crown?"

"And she replaced Twilight's with this one," Spike says while showing the princess the fake.

Princess Celestia takes a close look at the fake and see that it resembles Twilight's crown a bit. She has a good idea what the crown is used for.

Princess Celestia starts to walk downs the to the halls as she explains, "She must have a goal that her heart's desire and Twilight's crown is the only thing that will do just that. As for the replica, she was hoping that you won't notice that this was not yours. And by the time you did, it will be too late to find your crown and element of harmony."

Twilight walks by the princess side as she listen to her hypothesis. She can see why Falling star will replace her crown with a fake.

But Twilight scaredly asks, "But I don't understand. Where did she go? Where did she take the crown?"

"You will soon know more about this world than even I do and…" Celestia explains then stop in the middle.

Princess Celestia makes a very sad look and says, "I was hoping to give you some more time before I have to ask you this."

With that, everypony starts to follow Princess Celestia and Twilight to the destination. They have trouble understand a few things, like when Celestia statement on hoping to have time. They agree to wait until they reach their destination to ask about it.

Everypony has gone into the room where the strange and magical mirror. Since Twilight and her friend see the thief going through there, they need to start from here first.

Princess Luna explains, "This is no ordinary mirror, it is a gateway to another world. A gateway that's only opens once every thirty moons."

Pinkie touches the mirror and happily says, "Sparkly."

Princess Luna tries to ignore Pinkie's silliness and use her magic to move Pinkie away from the mirror.

Then Princess Luna explains, "It was always kept in the throne room of Canterlot Castle, until it was put away after the fire long ago. And when Princess Cadence took over the Crystal Empire we sent it here for her to watch over."

"So she went in there?" Fluttershy asks pointing to the mirror.

"Yes," Princess Celestia answers.

"Sounds cool! What's in this other world?" Rainbow Dash asks with excitement.

But Twilight looks at Princess Celestia with a concerned look and asks, "But princess, you said there's something else you need me to do that involves going to this other world, what is it you need me to do?"

Princess Celestia makes a sad look on her face and still uncertain about telling Twilight about this big favor. She then looks at her sister and sees her nodding her head meaning she thinks it will be a good time to tell her.

Princess Celestia looks at Twilight and says, "I know I'm asking very much of you, but I need you to find her and see if she's alright."

"Her?!" Twilight, Spike and the girls say with a shock.

Princess Celestia nods her head and says, "I know I should have told you this, but I don't have physical proof about Sunset's disappearance."

Rainbow Dash surprisingly says, "Wait, are you saying that Sunset Shimmer has been in this other world the whole time?"

Princess Celestia nods her head and says, "Yes. I knew I needed to tell you eventually, but I was hoping to have more time before I have to tell you."

"So in a way, Sun really is Sunset Shimmer after all," Applejack replies.

Then Twilight asks, "So you also want me to find her and check to see if she's alright?"

"Yes," Princess Celestia.

"Do you want me to bring her back to Equestria?" Twilight asks.

Princess Luna comes up to Twilight and says, "What Sun decides will be up to her. She developed a life in this other world so it will be her choice if she wants to remain in the other world or return to Equestria."

Twilight nods her head and says, "I understand."

"Good. But right now, there is this other matter we have," Princess Celestia replies.

Then Cadence says, "Twilight, you must use the mirror to go into this other world and receive your crown. Without it, the elements of harmony have no power and Equarea is left without it's most important means of defence."

Twilight and her friends look at the mirror and they are kind of concern about this other world.

Then Princess Luna says, "Your crown does not belong in the place Sun calls home. And in Falling Star's possion, it will no doubt be used to bring harm to her and the other inhabitants in this other realm. They will not have the power to defend themselves."

Twilight looks at the mirror and see that getting her mirror and finding Sunset Shimmer are very important. Princess Celestia levitates a saddle bag on to twilight with stuff she might need for the trip to the other world.

Princess Celestia walks over to Twilight and calmly asks, "You understand the importances of this task?"

"Of course," Twilight answers.

"Good. then you must go at once," Princess Celestia replies.

Twilight takes a deep breath to calm herself down and starts to make her way to the portal.

Just then Rainbow Dash flies between Twilight and the portal and says, "Woah, woah, woah! She's going, we're going too, right girls."

The girls agree to the idea about going with Twilight to the other world.

"Ooh! This is nervouscited!" Pinkie happily screams.

Applejack turns to Pinkie and bluntly says, "You do realized that's not a real word right."

Twilight feels happy that her friends doesn't want Twilight to go there along. But her cheerful smile is going to be turn upside down.

Princess Celestia firmly says, "I'm afraid I can't let you go."

"What?! Why not?!" Rainbow asks sounding upset.

"Sending all of you could upset the balance of this alternate world. Creating havoc that will make it impossible to get the crown back from Falling Star," Princess Celestia explains.

"And with Sun having similar friends to you, it might make it more confusing for the beings of the other world," Princess Cadence adds.

Then Princess Celestia says says, "That true. This is something, Princess Twilight must do on her own."

Then Princess Luna uses her magic to project the moon in the night sky as she explains, "Time is of the essence. On The third day, when the moon reaches the center of the night sky, the gateway will close, and once it does, it will be another thirty moons before you are able to return."

After hearing her friends support, Twilight makes her way to be at front of the portal. She touches the portal with her hoof and feels skeptic about going through. But knows that she needs to find her crown and Sunset Shimmer in the other world. Twilight then starts to go through the portal.

Spike becomes so scared of Twilight's well being, that he sprints and run towards the portal. The girls see this and aren't able to stop him.

The others scaredly screams, "Spike! No!"

But it's too late. Spike has gone through the portal with Twilight. The two travelers are now being pulled through the mirror, not knowing what will goes on in this other world. They know that their mission is very important and their adventure to the other world is only the beginning.
