Author's Note
Just a quick side note: The parent’s names that I used were already created by Princesstwilight12200 (I had to give her proper credit.) I just really like the names that she made up for the King and Queen. 
Also, this story is base from my ideas and aren’t really inspired by anyone else. Oh and furthermore, I would deeply appreciate some criticism on how to improve it down below in the comment section. Just don't be too rude, ok!? That is all, I hope you enjoy! 
Prologue
The Alicorn King who rules the day and night sky. With a coat as dark as the midnight sky and his mane being violet like the galaxy. He lived in the Palace that was on the floating island known as Unicorn Topia. Mostly, Alicorns and some noble ponies would live on this floating island. The King had absolutely everything he has ever wanted, except for one thing; a mare of his own. That was, until one night where we met his soulmate...
“Ahem?” a servant uttered, trying to get his attention.
“King Chronos… It’s time to look for your Mare.” a fellow servant of the palace said, while still bowing at him.
“OF COURSE, WE ARE REA-” he said in his royal voice. “MH-hm… I mean... I am ready.”
A loyal servant carefully used his magic to place a crown on the King as he walked out of the bedroom, steadily heading down to the ballroom. He was walking down one flight of stairs as he seen out of the corner of his eyes a mare that was so lovely that he couldn’t take his eyes off her.
“Ahem… your highness…?” A loyal servant quietly questioned the King trying to get him to acknowledge the crowd in front of him.
“Oh…” he thought. “WE ARE KING CHRONOS OF UNICORN TOPIA!” he basically shouted in the royal voice once again. “MARES AND COLTS, WELCOME TO OUR PARTY.” he said a little quieter.
As he finished talking, everypony bowed down as the King started walking again, down the second flight of stairs. He stood up tall and waited for everypony to stop bowing for him to walk forward. As everypony got back up, King Chronos saw the mare who caught his eye once again. “She’s absolutely lovely” he thought to himself. “I must find out who she is.” Before he even got one step closer to her, she started to walk away. “Oh no, I must stop her”
“Ahem, your highness…” a dark coated mare stepped up to him, making him stop in his tracks. “I am Princess Lil-Lillian-” she stopped as she noticed a really strong glare from somepony behind her. “Umm… nevermind, your highness.” she quickly said, giving a bow and then running away from the King.
“Huh?” he thought to himself as he watch the mare dash on by and before he even realized it another mare stepped up in front of him.
“Good evening, King Chronos.” she said giving a slight nod for acknowledgement to him. “I am Galaxia. Daughter of Artic Sun and Acapella.” she nobly announce.
“Finally!” He gave her a grin. “It’s nice to meet you Galaxia. You are absolutely beautiful.” “Oh wait… did I say that last part out loud?” he questioned himself.
She tilted her head away for a moment, lightly giggling to herself.
Galaxia was just an impressive looking kind of Alicorn and she wasn’t even royal. Her coat was crystal clear white with rose gold socks that goes up to her knees and her hooves had a lovely shade of violet. Even her mane was gleaming with her gold locks and violet ends. Honestly, King Chronos was shocked to find out that this mare wasn’t a Princess of some kind.
The orchestra started playing a slow song. As King Chronos noticed this, he thought to himself, “This is the mare that I wish to give her my heart.” He shook his head letting his thoughts disperse. “Miss Galaxia,...” he started out saying, “WOULD THOU LIKE TO DANCE WITH US?”
Galaxia was taken a little bit by surprise. She giggled to herself, “I would love to!” she cheerfully said.
She reached out to take his hoof and they practically danced the night away. King Chronos wouldn’t even dare look at another mare, because he knew right there that she was the only mare for him.
During this night, he confessed to her and asked for her hoof in marriage. She practically cried right there as he confessed. Galaxia was thinking that Chronos was the only colt that she could ever love also. Of course, she said yes to the King of Unicorn Topia. But she didn’t said yes, because he was a King. Galaxia said yes to him because she fell in love with him as he was walking into the ballroom, it was love at first sight.
After a few years of marriage, they found out that Queen Galaxia was pregnant with a little filly. For about eleven months, while passing time for the young filly, the King and Queen of Unicorn Topia thought of many names and also wasted no time to design the filly room for her. The King Chronos and Queen Galaxia tried to remain calm in the public eye, but in the palace they showed their excitement as much as possible with small celebrations here and there for the new filly.
As soon as it was time for the young filly to come out, they wasted no time to get a doctor in to the palace to deliver her. The little filly had a pearl white coat and her mane was blush pink. You could obviously tell that she took her looks from her mother, a look from an angel.
King Chronos smiled, “She looks so similar to you, my dear Galaxy. She’s definitely the light in our hearts.”
Queen Galaxia giggled, “Well, of course she it! She is my daughter. I expect nothing less from our sweet little angel.”
The King and Queen could tell that this little filly would be a bright young mare who when she’ll grow up would help so many ponies.
“Angel?” King Chronos thought to himself. “So, how about a name that means ‘Heavenly.’ Like, Celestia?”
“Celestia…” she uttered. “That’s a lovely name. Celestia it is then.” she smiled.
“I can see her now, being as strong as her own parents.”
The Queen just smiled at they new little filly. Queen Galaxia could definitely tell that their little one will face some hardships that may never appear in any other pony. But this is the difficulty for a Princess.
Five years have passed since Celestia was born, and the Queen became pregnant yet again. The King was even more excited this time around. He hope to get a colt or filly that look similar to him, but then again if the little one looked more like his mare he would still be happy. Again, they thought of so many names for their new little one. The only problem with this one was that they couldn’t tell what gender it was going to be before it was born. So, the King and Queen had a little hard time designing the room. An eleven months passed, it was a filly! She was the complete opposite from Celestia. Her coat was almost midnight blue with her mane being a lighter shade of blue.
“My dear little filly, my little moon.” King Chronos said.
“Moon?” Queen Galaxia questioned… “Then, how about Luna?”
“LUNA!” Celestia yelled out filled with excitement that she got a little sister.
The little filly almost bursted in tears. “Shhh… It’s ok, Luna.” King Chronos quietly said to her. “Celestia, we need to learn how to use our inside voice. Ok?”
“Ooohhh… Oopsie! Sorry, Daddy.” she said, pouting.
Little did either one known, that this was just the beginning for Princess Celestia and Princess Luna.
