Equestria Girls: Through the Mirror

Eleanor's POV.
Twilight, Spike and I were sleeping soundly and quietly, until there was a sudden sound of falling and the door swinging open.

Spike and I woke up with a gasp and looked around, "What?"

Twilight woke up in a stir and saw a Pony at the doorway, wearing a hooded cloak, carrying her crown in her arm. Twilight gasped and shouted, "My crown! She’s got my crown!"

The thief opened the door and charged down the hallway. Twilight and I jumped out of bed and chased after her, "Stop! Thief!"

The others woke up and exit their rooms. Twilight dashed past them, "She’s stolen my crown!"

Twilight and I chased after the thief. I took off into the air and blocked the Pony's path. The Pony and I clashed into each other. She tried to push me out of the way, but I was pushing back, to stop her from escaping.

"Stop!" Twilight shouted and to ran to meet up with us.

With a smirk, the Pony used magic to disappear in front of me, leaving the cloak over my face. She reappeared behind me and smiled at me. I removed the cloak and looked at the Pony.

She was definitely female. A Unicorn mare with amber-golden fur coat. Cyan eyes and a red mane and tail with yellow streaks. She wore a purple tank top, with a leather jacket, and an orange-golden skirt.

My eyes widened and I gasped. I thought I would never see her again. I thought she was gone for good. My blood ran cold. I couldn't move.

Sunset Shimmer!

Sunset Shimmer smiled at me and resumed running down the hallway. The other girls ran past me and chased after her. Twilight leaped and caught Shimmer. The two rolled into a study room, with a familiar mirror inside. The crown bounced out of Shimmer's arms and into the mirror.

The Girls gasped, while Shimmer smiled.

Twilight turned to Sunset Shimmer, "What did you do with my crown?"

"Sorry it had to be this way..." Sunset Shimmer answered, then teleported toward the mirror, "Princess."

Without hesitation, she charged into the mirror. Twilight and the girls gasped.

"Who was that?" Fluttershy asked.

Twilight turned to me, I rubbed my arm in discomfort, "You know her, don't you, Ellie?"

Ashamed and shaken from what has happened, I nodded my head.

"Well? Who is she?" Rainbow Dash asked me.

"What happened?" Celestia asked, appearing from behind us.

"A Unicorn stole my crown and took it into that mirror." Twilight explained, pointing to the mirror.

Celestia looked at me, "Was it her?" I nodded.

"Who is she, Princess?" Rarity asked.

*Later, That Morning...*
"Sunset Shimmer, a former student of mine and Eleanor's first friend in Equestria." Princess Celestia explained to Twilight and the Girls, "She began her studies with me not long before Twilight. But when she did not get what she wanted as quickly as she liked, she turned cruel and dishonest. Eleanor and I tried to help her, but she eventually decided to abandon her studies and pursue her own path. One that has sadly led her to stealing your crown."

"She replaced Twilight’s with this one." Spike spoke up, showing us an identical tiara, except the gem was obviously fake.

Celestia looked at the tiara, "I suppose Sunset Shimmer thought you wouldn’t notice right away that this was not yours." She started walking down the room, to the study, Twilight followed after her, "And by the time you did, it would be too late to go after your crown and Element of Harmony."

"But I don’t understand!" Twilight shook her head, then asked, "Where did she go? Where did she take the crown?"

"You’ll soon know more about this place than even I do." Celestia answered calmly.

With that, the Princesses, the Girls, Spike, Twilight and I returned to the study, where the mirror was located.

"This is no ordinary mirror." Princess Luna explained, "It is a gateway to another world, a gateway that opens once every thirty moons."

Pinkie Pie put her hand over the mirror's surface. It sent ripples and a magical shine, like a magical pool of water. Pinkie smiled, "Sparkly!"

Luna rolled her eyes and pushed Pinkie away from the mirror, "It has always been kept in the throne room of Canterlot Castle. But when Princess Cadence took over the Crystal Empire, we sent it here for her to watch over."

Celestia let out a heavy sigh, behind us, "I had always hoped that Sunset Shimmer would someday use it to return, to come back to Equestria seeking my guidance. Obviously, this is not what has happened."

I rubbed my arms. I missed Sunset Shimmer so much. I still blame myself for her leaving and this happening to her. If only I helped her stay in her room and focused her studies for the exams... Or said no...

Princess Celestia put her hand over my shoulder, "It's not your fault, Eleanor. You did what you thought was right."

I regained my smile. Then Cadence spoke up, "Twilight, you must use the mirror to go into this other world and retrieve your crown. Without it, the other Elements of Harmony have no power and Equestria is left without one of its most important means of defense."

Twilight walked toward the mirror and nodded in determination. The Girls and I looked at each other.

"Your crown does not belong in the place Sunset Shimmer now calls home." Luna explained, "And in her possession, your Element of Harmony will no doubt be used to bring harm to the inhabitants of this other realm. They will not have the power to defend themselves."

Twilight grabbed her backpack from Luna.

"You understand the importance of your task?" Celestia asked her protégé.

Twilight nodded, "Of course."

Celestia nodded, "Good. Then you must go at once."

Twilight took a breath and approached the mirror. Rainbow Dash quickly jumped in front of Twilight, "Whoa, whoa, whoa. She’s going? We’re going with her." She turned to us, "Right, girls?"

The Girls and I nodded in agreement. Pinkie grew a Cheshire grin, "Oooooh! I’m so nervicited!"

"You do realize that’s not a real word, right?" Applejack asked with a raised brow.

Twilight smiled, but Princess Celestia shook her head, "I’m afraid I can’t let you go."

"What?!? Why not?" Rainbow Dash exclaimed, stomping her hoof.

"Sending all of you could upset the balance of this alternate world, creating havoc that would make it impossible for Twilight to get the crown back from Sunset Shimmer." Celestia explained, "This is something Princess Twilight must do alone."

"Time is of the essence." Princess Luna spoke up, using her magic to show a projection of the moon, "On the third day, when the moon reaches its peak in the night sky, the gateway will close. And once it does, it will be another thirty moons before you will be able to use it to return."

With that, Rainbow Dash stepped aside, letting Twilight approach the mirror. Twilight reached into the mirror, but hesitated to enter. She turned to Celestia, who nodded in agreement. Twilight took a breath then looked at me. I walked over to her. Twilight threw her arms around me and hugged me tightly. I hugged her back.

Stay safe, Twilight.

Twilight released the hug and entered the mirror.

Unable to fight back his instincts, Spike charged toward the mirror.

The Girls cried, "SPIKE, NO!!"

Spike pushed past me and entered the mirror. The impact of the collision caused me to lose my balance and fall into the mirror as well. The last thing I saw was a colorful vortex and powerful magic making my head hurt, before my vision went black.
