The sun was setting and the moon was starting to be raised into the sky. The guards near the front gate looked at the moon squinting, trying to see if they could spot Princess Luna.

“I think I can see her.” He pointed to a spot of light near the moon.

“It could just be a star.” The other guard said.

Princess Twilight Sparkle teleported with a flash of magic near the front gates of the castle. The two guards noticed the flash of light and turned to see her.

“Princess Twilight, so nice to see you again. We were not informed of your visit.” One of the guards said.

“I know, sorry to drop in unannounced, but I really need to talk with Princess Celestia, it’s really important,” She said, looking like she was in a hurry.

“Very well. Follow me Princess.” He said opening the gate with his magic, which he then proceeded to lead Twilight inside.

Twilight looked around, noticing that most of the staff had gone home for the evening, which made the castle feel empty. The torches started to self-ignite with igneous magic, lighting up the hallways as the sky outside became darker.

Princess Celestia was in her office looking over the scrolls. Some she gave her royal hoof of approval and others went into the rejection box on the side of her desk. Using her magic, she floated a tea cup up to her lips and drank from it. A knock came to her door as she put down her cup.

“Yes?” She asked, calling out.

“Sorry to disturb you, but Princess Twilight Sparkle is here to see you.” The royal guard replied.

“Let her in please, thank you,” Celestia said, surprised and looked at the grandfather clock noticing the time of day.

Two large doors opened and Princess Twilight walked in looking tired.

“I apologize for coming at this time of the day, but I really need to ask you about the mirror,” She said, noticing the plate of cookies as her stomach let out a growl.

Celestia sighed, noticing Twilight’s stomach growled and passed her the plate. “Unfortunately, I do not have good news for you. Me and my sister have been trying to repair the damage, but we have been unsuccessful.” She sitting up and glancing out the window before turning back to Twilight.

Twilight swallowed down a cookie. “There has to be something we can do or Sunset will never be able to come back.”

“She still has time to return, but just in case, I have asked your sister in law Cadance to check the Crystal Kingdom’s library and archives,” Celestia said opened a lower drawer in her desk.

A scroll floated to Twilight as she read the letter from Cadance and then looked at Celestia.

“There is a second mirror?” Twilight said and gave the scroll back to Celestia.

“It’s missing, and may not even exist anymore, Twilight after all the chaos, King Sombra caused many things were lost,” Celestia said with some frustration.

The sound of the clock ticked away as the two became quite. Twilight did not like feeling useless and wanted to do something to help.

“Sunset is trying to recover the green gem of disharmony on her own. Princess Celestia please, allow me to go through the mirror, I want to help Sunset.” Twilight looked determined.

“NO!” Celestia voice boomed back looking serious.

“WHY NOT?” asked Twilight looking hurt.

“If you go through that mirror, and it breaks, you may never be able to come back,” Celestia said walking up and looking her in the eyes.

“It’s a risk I am willing to take.” Twilight stomped her hoof down with a loud clop.

“What about your friends here, the elements of harmony, your title as Princess?” Celestia said making a point that Twilight could not ignore.

“Well, they um,” Twilight lowered her head realizing.

“I wish that the mirror never existed, that way Sunset would still be here, and you would not be thinking about leaving me as well.” Celestia started crying.

“I would not, Celestia… you are always right. I am wrong for coming here, sorry.” She said, looking down and started for the exit.

“Twilight wait,” Celestia said using her magic to lock the doors. She then sat down and opened another drawer and pulled out a large book with her magic.

Twilight had a look of curiosity as she walked back to Celestia who opened the book, revealing photos of young filly unicorns. Each page was full of photos from different years.

“This book has photos of every student who has attended my School for Gifted Unicorns,” Celestia flipped through the pages with her magic. “Some turned out to be very talented and now have a place in Equestria helping those in need,” She flipped to another page and one photo showed Trixie. “and some who did not.” Celestia frowned and then flipped to a page which had a photo of Twilight looking goofy with her large glasses.

“Oh, goddess I can’t believe I used to need glasses.” Twilight covered her face in embarrassment.

“You looked adorable,” Celestia grinned and then stopped at a photo next to her that was flipped over. “Now do you remember who went to class with you?” She asked.

“Well, I remember Spike was there.” Twilight rubbed her chin with her front hoof.

Celestia flipped the photo revealing a younger Sunset who looked camera shy.

“Sunset Shimmer! I don’t remember, are you sure?” She felt a small ache in her head.

Celestia horn started glowing which she soon tapped Twilight's head, causing her to feel dizzy as new memories flooded her mind. There was silence for a few minutes as Twilight looked to the photos, touching the one with Sunset on it.

“I remembered. Both Spike and Sunset were in my class,” Twilight rubbed her chin again and then put her hoof down. “Well, that does explain some of the strange visions I get from time to time.” She said and looked at Celestia realizing what she did. “Why did you take my memories?” Twilight said sounding angry.

“Twilight I am not always right. I took your memories of Sunset when I should have not.” Celestia said and removed her locket from her neck and placed it around Twilight's neck.

“Celestia, what is this?” Twilight touched it looking at Celestia.

“Open it and you will understand,” She said knowing that the time for secrets is over.

Twilight opened it and gasped at what she saw and looked at her.

“Twilight I want you to go to the Crystal Kingdom and find Cadence. Then help her find that second mirror.” Celestia said as she nuzzled her and then whispered something else into her ear. “Please give my daughter that locket if you are successful in your mission.”

Twilight paused for a moment and then looked up at Celestia and quietly nodded. “Yes, of course, your majesty.” She bowed now feeling that she could help and smiled.

“I will call for my fastest escort to take you there.” Celestia unlocked the doors and started walking towards them.

“Thank you, but I know a faster way there.” Twilight backed up and closed her eyes as her horn started glowing bright purple and then she disappeared in a flash.

“Did she just teleport halfway across Equestria?” Celestia said to herself and shook her head in disbelief. “That child is truly amazing.” She smiled and opened the doors.

“Is everything alright your majesty?” The guard said, noticing that Twilight was gone from the room.

“Yes of course. Please send a message to Cadence and Shining Armor, that Princess Twilight will be arriving there very soon. She is to help with the search for the missing mirror.” Celestia said, yawned. “As for me, I will be retiring for the night.”

Author's Notes:

I know a very short chapter.

Thanks to Dreagknight for help with the corrections.

It is easy to get carried away with writing and over look some obvious mistakes.

This happened in Equestria around the same time the Dazzlings were working on the stage.

Considered added to chapter 19 but I will fit it between 18 and 19.

Thanks for reading.

Chapter 20 is coming soon.
