Secrets Revealed

Luna would gaze at her sister few a few moments, taking the time to process what Celestia had just said. She was thinking about how the modern ponies of Equestria would react, but she knew it would be for the best. The Moon Princess agreed with her sister's decision.

"Of course, sister," She finally said. "It is for the best after all."

Celestia did a sigh of relief, happy that her sister agreed with her. Like she said, it is for the best. The modern ponies deserved to know about their parents and that they used to rule Equestria before them. The Sun Princess wanted to tell Twilight and her friends about this first though. Not even Spike. She would have to wait for him. For now, she trusted her former faithful student and her friends.

"We will tell them in the morning," Celestia said, yawning, finishing her cup of tea. Luna went back to go check dreams and she went back to her bedroom, falling asleep.

...

The next day, Celestia woke up bright and early so she could send a scroll to Twilight. She grabbed a quill and ink with her magic and started writing.

Dear Twilight,

I'm writing this letter to you because I need you in Canterlot so I could tell you and your friends something that me and Luna kept for so long. I think we have been silent long enough and I think that it's the time to tell you and the others. Please don't bring Spike yet. I feel like this is something I should share with just you girls for now.

Your friend and former teacher,

Princess Celestia

She then sent the scroll. When Twilight got it, she read it. She wondered what Celestia had to tell them but she knew that she was about to find out. The former student of The Sun Princess let her assistant know that she was going to Canterlot and that he had to stay here. He didn't mind. He was going to do a hangout with Big Mac and Discord tonight anyways. She was then off to go inform her friends and head to Canterlot.

...

After Twilight informed her friends about the letter, they all then took the train to Canterlot. After a few minutes of riding the train, they were at their destination. The royal guards let them in and then they were inside the castle. Twilight looked around the castle for Celestia.

"Celestia?" She called out. "Where are you?"

There was no response for a few moments. The former student of The Sun Princess was about to call out her name again but she heard her call. She walked downstairs, approaching the other alicorn.

"Hello, Twilight," Celestia said with a nervous expression on her face. Her former student would look at her with a concerned look on her face.

"Princess, are you alright?" She asked. Celestia didn't know how to reply to her question. She didn't want to simply lie to her so she decided to be truthful with her. After all, she wears a mask everyday.

"No, I'm not..." She replied with guilt in her voice. The Sun Princess then spotted her sister and then thought it was time to head to the throne room.

"Come with me," said Celestia, heading up to the throne room, Luna following her also. Twilight and her friends then followed the two princesses up to the throne room. When they got to their destination, Celestia and Luna sat on their thrones and the Mane Six sat on the floor. The eldest sister cleared her throat and then she began.

"It's something about Equestria's past..."

Twilight was starting to get interested in this.

"What about it, princess?" She asked.

The Sun Princess took a deep breath.

"My parents... used to rule Equestria..."

The Mane Six gasped. They couldn't believe what they had just heard, but Twilight was most shocked out of all of them.

"Y-You're parents used to rule Equestria?!" Twilight said in a shocked voice.

Celestia nodded. "They were also a king and queen..." she added. Twilight's mouth was wide open when she just heard what she said. Applejack was confused.

"Wait a minute! Equestria had a king and queen before ya'll two ruled?" Applejack asked.

"Yes..." Celestia replied. "They ruled Equestria many years ago. They were killed by Discord's parents. That's when me and Luna took the throne. It is a painful thing to remember but I always know they are still with us."

The Mane Six gasped.

"They actually got asked to rule Equestria by Star Swirl and were actually his students. Not me and Luna," She continued.

Twilight was shocked. "W-What? Star Swirl wasn't actually your teacher but your parents?!"

Celestia nodded. "The fact that Star Swirl was me and Luna's teacher was a made up lie by us... well, mostly me..." The Sun Princess found it hard to admit the truth.

"Y-You lied?" The former student of The Sun Princess was shocked that she told a lie. The Sun Princess felt guilty.

"Yes..." She admitted again. "They were two alicorns, including my father. He was the only male alicorn some ponies had ever seen. "The only ponies that have seen my parents were the ponies that lived during the ancient times of Equestria." She explained. Celestia then remembered something. She remembered when she first met Discord and she decided to tell them how they first met.

"Also, there's something I should tell you about Discord..." She said. "Luna, stay here. I'm going to send a scroll to Discord."

Celestia would use her magic to grab a quill and ink and she started writing to Discord. When she was done writing, the letter was then sent. Discord later got it and he read it.

Our past... Discord thought. He then flew off to Canterlot.

...

After a few minutes, Discord arrived. He looked at the Mane Six and then he looked up at Celestia.

"I'm here!" he said.

"Alright," Celestia took a deep breath and then spoke. "Discord and I used to be best friends..."
