A/N: Hello once again! I've decided to do this story alongside with Smarty's Hearth's Warming Eve story which is bound to be released late-November to early December. This story takes place during the first book "Romance of Unicorn Hearts". Now, I hope you all enjoy this, as it takes place in the Equestria Girls universe. You can decide if this is canon in the Smarty Heart universe or not, I'll have you make the decision. Now... onto the Prologue!

Luna's moon shone high above in the sky with three of the brightest stars above it. It was sort of a special time of the year where the brightest stars near the Equis system would shine bright at their highest solar peak. It was the special event in which the stellar event was called "The Three Lunar Stars". The event would happen every thirty moons and has been happening since the thousand years when Nightmare Moon was banished to the moon.

Below the stars and moon, the Crystal Empire was at peace and the Crystal ponies were trotting through the streets of their peaceful empire. The latest news was heard all over Equestria as seen by a stand of newspapers. Twilight Sparkle, the student of Princess Celestia had become a princess herself. And she was coming to stay at the Crystal Palace where Princess Cadence, the ruler of the Crystal Empire was.

The train pulled by and out stepped the Princess of Magic with her children and the now-announced Prince Smarty that she was happily married to. Besides Smarty, her friends were there along with Spike and her little brother Theo with his friends Spark and Loki. They got off the train with everypony from the Empire bidding them welcome.

The princess and prince held onto their children Starlight and Dream Charmer when trotting through the city at sunset to arrive at the Crystal Palace. Pinkie Pie, Rarity, Rainbow Dash, Applejack and Fluttershy had never been happier with their two friends Twilight and Smarty now that they were of royalty.

"Hoo-wee! Your very first princess summit. You must be over the moon, Twilight." Applejack said to her lavender alicorn friend.

Twilight was excited to be a princess, but was feeling nervous about two things. But she was keeping Black Darkness aside to focus on what was happening at the moment since the Coronation. Twilight said "Oh, I am excited. But to be honest, I'm a little nervous too."

Pinkie Pie trotted over to her and said "You're nervicited! It's like you want to jump up and down and yell Yay Me! But you also want to curl up into a teeny-tiny ball and hide at the same time! We've all been there!" Fluttershy tapped Smarty's shoulder and he turned to look at his friend, as she quietly said "I'm there almost every day."

Applejack placed a hoof on her friend's shoulder and said "You've got no reason to fret Twi. Everything's going to be just-"

"TWILIGHT!" Rarity interrupted, noticing Twilight was missing something valuable. "Oh, I'm sorry darling… but I realized that you're not wearing your crown. You haven't forgotten it back in Ponyville, haven't you?"

Twilight turned to Spike and Theo and his friends who were guarding the bag and she said "It's in my bag. I just feel a little self-conscious about wearing it. Haven't really gotten accustomed to these wings yet either." She passed her daughter Dream Charmer to Pinkie, then lifted herself off the ground and tried to stay in the air for a couple of seconds, but fell flat on the ground.

Smarty took his princess' hoof and helped her off the ground. "Thanks Smarty." Twilight said, smiling at her husband. Smarty just smiled at her and said "No problem, my love." The flirt had caused Twilight to blush lightly, before she planted a gentle kiss on his lips.

Rarity approached Twilight once again and said "You are a princess now Twilight. Embrace it! I'm telling you, if I had a crown like that, I would never take it off. Why, I'd sleep in the thing." Twilight just smiled and held Smarty's hoof as she, him, their children and the rest of their friends trotted straighted into the Crystal Palace, ready to see what was in store.

The group entered the Crystal Palace's throne room, the very room where Smarty fought King Sombra and defeated him with the help of Twilight and the Crystal Heart. A royal guard blew into a horn to announce the arrival of Princess Twilight and Prince Smarty.

The purple and lavender alicorns trotted forward into the throne room, smiling when on the approach towards the three princesses. Along the way, Twilight bumped into one of the guards. An orange pegasus with gold guard armor. She quickly apologized and moved forward, putting her hoof around her prince.

The guard that Twilight bumped into cleared his throat and announced "Your Highness! Princess Twilight Sparkle and Prince Smarty Heart!"

Princess Cadence came trotting down towards the alicorns with the greeting smile on her face and said "Hello Twilight! Hello Smarty! I haven't seen both of you since the coronation, it's so good to see you!" Warp was there and he came galloping towards his buddy Smarty, giving him a warm welcoming hug. "Welcome Smarty." Warp said, smiling. The princess of the sun finally came down and looked at the new princess, her prince, her children and the rest of her friends.

"We have so much to discuss. But it can wait until tomorrow, you all look tired from your journey. Now off to bed, all of you." Princess Celestia said, smiling and proud to see Twilight and Smarty with their children and friends.

Twilight, Smarty and Spike finished putting their children into the cribs to have a good night's rest. Smarty began to work on the bed to set up for him and Twilight, and Spike was assisting Twilight to take out the things from her bag. Twilight took her crown from her bag using her magic and placed it upon her head. She took a look at her reflection in the mirror and softly sighed. Smarty looked up and trotted over to her.

"What's wrong, my love?" Smarty said, moving his gentle hoof to her and giving her soft and silky mane a calm stroke.

Twilight looked at Smarty and said "I don't know Smarty… I'm just worried. About both Black Darkness and how I'm a princess. Cadence was given the Crystal Empire to rule over, what if Celestia expects me to rule a kingdom of my own?"

Theo jumped over and shouted "That would… be awesome!"

"No it would not!" Twilight disagreed with her little brother. "Just because I have these crown and wings, it doesn't mean I'll be a good leader."

Smarty took her hoof and guided her to their bed, slipping into bed. Spike got onto his bed and said "Sure you will Twilight. Now you and Smarty should get some shut-eye. Big day tomorrow!" before he tucked himself in and went to sleep. Theo also left the room to go to sleep with his two other friends, Loki and Spark. Smarty then looked at Twilight and used his magic to place her crown off her and onto the nightstand.

Twilight gently began to cuddle with Smarty when she lay in bed with him. The prince and princess soon fell asleep together in bed, holding each other in love… until Twilight's wings sprung open. Twilight force-tucked her wings shut while she said "Just trying to get comfortable, wings!" When her wings closed, she closed her eyes and started to sleep…

…Her wings opened again and the sheets flew up, waking up Smarty wondering if Twilight was frustrated with her new wings that she just earned. Smarty just closed his eyes, knowing his sweetheart would get used to her new wings soon.

I don't own My Little Pony: Friendship is Magic or Equestria Girls! If I did, I wouldn't be writing this! The Smarty Heart, Starlight and Dream Charmer OCs are made by me while the Loki, Theo and Spark OCs were suggested by D.J. Scales.
