As Princess Celestia headed towards the royal bedrooms, she was nervous. She was unsure as to how Luna would react to the secret that she was hiding but had a strong feeling that waking her sister during the day would cause any reaction she would have to be rather unpleasant. When she finally reached Luna's door she said to herself, "Well here goes nothing."
She knocked on the door rather loudly and immediately heard a yell, "Sister, why are you disturbing my slumber?"
Celestia opened the door and headed into find her sister with her horn lit. It was obvious that like she always was when she was woken up like that, she was in a foul mood. Luna gave Celestia a glare and asked, "What is it? Why did you wake me from my slumber?"
Celestia held her head low and replied, "Sister, I have some news that may interest you." She saw her sister's glare lessen as she continued, "Unicornia has returned."
Luna's eyes grew wide as she asked, "Really, Starlight is back?"
Celestia replied, "Yes. When I discovered this, I sent Twilight and her friends down there to try and get her to reverse the spells. Thing is, Starlight told them that she will only undo the spells if she can meet with the three of us."
Luna asked, "Three of us?"
"Yes, you, Discord and myself."
Luna asked, "Did she tell Twilight about her origins? Does Twilight know that Starlight is your daughter?"
Celestia replied, "She does but I have to admit something to you and it involves Twilight."
Luna knew how close her sister and Twilight had always been. She also knew that Twilight had more power than most ponies and became very curious about why she would bring up something involving Twilight. She then became suspicious, "Celestia, are you saying?"
Celestia held her head low and replied, "I am."
Luna used her magic to open her curtains before yelling, "Sister, how could you hide this from her? How could you hide this from me?"
Celestia sighed, "Because I didn't want to stir the pot any! I didn't want to disrupt Twilight's life any and it didn't even cross my mind to tell you."
Luna calmed down a bit before asking, "Does Twilight know about her true origins?"
Celestia replied, "Well she didn't until Applejack figured out I was hiding something and ultimately I did tell her and well...." Celestia began to cry, "And I think she hates me now! I think she hates me as much as Starlight did when we turned Discord to stone."
Luna threw her hooves up in the air in frustration and yelled, "Sister, how could you do this to Twilight and also, why didn't you raise her on your own? Why did you pawn her off on somepony else?"
Celestia sighed, "Luna, you know how Equestrian culture is now. We are held to different expectations now than we were back when Starlight was born. We weren't viewed as goddesses back then, royalty giving birth was viewed as normal, it wasn't by the time Twilight was born."
Luna had a deep scowl on her face she was so upset with her sister. She did want to know more though, "So, who is the father and are there any others? Did you give birth to any others while I was on the moon?"
Celestia held her head low and replied, "Regarding the father, it is the captain of the Manehattan Guard, Steel Shield and there is one other and his cutie mark is very similar."
Luna gasped, "What, Shining Armor is yours too?" She glared deeply at Celestia and added, "Well you need to let Shining Armor know and you need to let Starlight know that she has two half-siblings, well if she will even see you after what we did to her father."
Celestia looked up and replied, "Well Starlight does want to see the three of us but before we go to Unicornia, we will have to go to the Crystal Empire and let Shining Armor know this and...." she paused before becoming more nervous, "I'm sure he will be pretty upset."
Luna replied, "I'm sure he will be but I want to know something about Cadence. You have often referred to her as your niece but that can not be because we have no siblings. What are her real origins?" She briefly paused before continuing, "Don't tell me she is your daughter too."
Celestia replied, "No, she is not my daughter. Nopony knows who her birth parents were but she was taken in by a couple of earth ponies in a village full of love until an enchantress named Prismia came along. She was very bitter that nopony loved her while everypony else in the village cared for one another. Ultimately she used a magical necklace to make everypony miserable."
"Really sister? What else happened?"
"Well Cadence ultimately confronted Prismia, the necklace amplified her love and she showed Prismia that she was loved. After that, she was transported into the same realm where I ascended Twilight. I ascended her, adopted her as my niece and then deemed her as the Princess of Love."
Given that all of this happened while Luna was imprisoned in the moon, she was unsure what to think of this. To her it seemed like a tall tale but she did know of one pony who would know, Princess Cadence. She replied, "Well I am having a hard time believing you but I shall speak to Cadence myself to see if you are telling the truth or hiding Cadence's origins too."
Celestia said, "Look, what I'm saying is the truth but still, we need to go to the Crystal Empire and let Shining Armor know that I am his mother so he won't be living this lie anymore."
Luna then wanted to know another thing, "I would like to know though, why is it that they were raised by Night Light and Twilight Velvet? Were they friends of yours, did they have a special status at one time or did you just pick two random ponies off the street to adopt them?"
Celestia sighed, "They were really good friends of mine at the time and I figured that they would be the perfect ones to raise them until they were...."
Luna cut her off, "Ready to come back into your life in one way or another, until Shining Armor attended the academy and Twilight passed her entrance exam?"
Celestia was starting to become frustrated with her younger sister and more firmly stated, "Look, we need to go and get all of this taken care of. Shining Armor needs to know and then we have to go to Unicornia so Starlight will know as well...."
Luna cut her off, "And get her to reverse those spells, correct?"
Celestia simply nodded and the two headed towards the throne room. Luna was not happy at all with everything her sister had hid from not only her but Twilight and Shining Armor. She was not sure exactly how things would turn out but did know one thing, that the relationships Celestia had with Twilight and Shining Armor would be very strained, perhaps equally as much as her relationship with Starlight was after they turned Discord to stone.
