I do not own any My Little Pony, if i did i would not be writing fanfic

Princess Luna had lots of questions some more important than others but one was the most important and she needed answers, and she knew only one pony who could answer them for her, her sister Princess Celestia. But at that time Luna had only just risen the moon, the first time in many countless years and Luna knew her sister would be somewhere in the castle but were she could only guess. Luna had travelled the castle halls looking for her sister wanting to desperately get the answer she wanted, first Luna looked into the food hall, but found nothing but empty cups of tea, she then tried the royal garden but still nothing, the a though came to her, "her room" Luna said aloud quickly turning and then running through the garden and then the halls of the castle making pony's in her path jump out of the way of the fast princess.

After running Luna eventually got to her sisters bed chambers, she was about to open the door when she had second thoughts, but after deciding that she needed to know she entered opening the doors with her magic.

Celestia was reading a letter from her personal student Twilight when her bedroom doors opened. Celestia moved the letter into her bedside draw which her magic and watched as Luna her younger sister walked into her bedroom, instantly she could tell Luna was troubled and a part of her knew why. As Luna walked in she could see her older sister sitting in her bed looking at her, Luna expected her sister to have her normal warm smile but Luna saw that her sister knew what she wanted to ask.

"Good evening sister" Celestia spoke first sitting up within her bed "why are you upset" Celestia said seeing the sadness and uneasiness with in her sister's eyes.

"Sister…err…I…I need… to know something" Luna said to her sister looking at the floor nervously

"Oh course Luna what do you need to know" Celestia asked her younger sister but knowing deep inside her what her sister was going to ask

Luna looked into her sisters eyes and asked "I…I need to know what happened to…her… I want to know what happened to her after you banished Nightmare Moon to the moon… I need to know".

Celestia took a deep sigh as she hung her head and then looked into her sister's eyes "Luna… I took care of her, just like you asked…forgive me sister" Celestia said dropping her head splitting herself from the gaze of her younger sister. "I wanted the young filly to have a new life…one away from the pain of your banishment to the moon…I…I wanted her to forget everything… to live a normal life, please forgive me sister" Celestia said tears dripping down her face and on to the bed.

Luna was shocked, her sister never cried around her but here she was crying right in front of her. Luna knew she would have done the same thing if their roles were reveres, Luna walked up to her crying big sister jumped on the bed and put her hooves around Celestia's neck and hugged her "I forgive you sister" Luna spoke gently into her sisters ears "I forgive you".

When slowly Celestia stopped crying Luna pulled away from their hug and looked directly into Celestia's eyes and smiled giving her older sister a smile that she had always given her when she felt upset. Then Celestia began to speak "When you went to the moon I took care of her…first I wiped her mind making sure she would not remember the horrors of our battle…then I hid her…I hid her with a small nearby loving unicorn family… and then I watched her grow up never knowing her birth right"

Luna listened to what her sister had to say, but as Luna listened she only one question left to ask "sister" Luna spoke "could I see her again please".

Celestia was caught up between two fires at that point; she did not want to hurt either of them as they were very special to her. Celestia knew she had no choice as she knew if Luna saw her now the little pony would be distraught but it would make her sister happy, but she also knew that if she denied her sister then it would make the her very miserable again and she knew Luna would never let it drop, Luna would find it out on her own in time. Eventually Celestia knew what she had to do. "Very well but not at the moment, I need time to prepare things"

"I understand sister thank you" Luna said again hugging her older sister making Celestia smile, "oh I'm sorry you want your sleep, I'll just leave" Luna said as she pulled back from the hug moving to the door "goodnight sister" Luna said happily

Celestia said a final good night to her sister, she knew Luna was much happier, but she knew doing what Luna wanted was going to be hard but she knew it would only hurt them both is she delayed it. With a deep sigh Celestia magically grabbed a piece of parchment and an ink quill soon Celestia started writing with her magic. After minutes of writing Celestia double checked to make sure every detail was perfect. Celestia read the letter again and again, the first line of her letter read "dear Twilight Sparkle" Celestia then used her magic to send the single letter. After she had sent the letter she knew there was no going back Celestia then decided to get some sleep, as she slept she had a dreamless night.

Meanwhile Luna was happily wondering though Canterlot smiling as happy as anypony could be "I'm going to see her again… Celestia is going to let me see her again" Luna thought joyfully "after a thousand years I can finally see her again…my daughter". All night Luna thought all about her daughter, "Did she have the same name? Where did she live? Was she ok" all though the night Luna could only think of questions she needed to ask.
