Twilight Sparkle still remembers the words of her love when her child was born.
"She's blind." Twilight said angrily.
"She may be blind, but she will be a force to be reckoned with, she may even be the object of your demise." Luna said before she left Twilight and the child.
About 14 years later, chaos struck Equestria. The Princess of Equestria, one who had been previously assumed to be the rational and innocent Princess of Friendship, had killed her eldest daughter, Dusk. Celestia and Luna had both left their powers to somepony. Celestia, assuming Twilight would continue to rule rationally as she had for several years before, left her power to her "Most Faithful Student."
Luna kept her heir, or heiress in this case a secret. In fact, it was the child, the newborn Silent Night, who had gained Luna's abilities.
As the child got older, stars began to appear in her mane. Since Luna was her "father", Twilight assumed nothing of it.
As soon as Dusk Dreamscape was killed, Silent Night had made her decision. She was to leave the castle, rebel against her tyrant mother, save Equestria from her wrath. The Crystal Empire, Cadence's kingdom, had receded from Equestria. Cadence had agreed to allow the Crystal Empire to be part of the Equestria once again, but when and only when Twilight was overthrown. She would do this, not only for her late sister, but for everypony who had suffered during her mother's currupted reign.
Dusk was not the only pony Twilight had as she said "Disposed of." Shining Armor had been killed. Cadence was able to save Flurry, who came out with severe injuries. She, however, passed away a week later. Both deaths devastated the kingdom, and even the princess of love lost the ability to spread affection across Equestria. Even her two other children born to her and Shining Armor, Love Birds and Crystal Bluejay, could see the difference in their mother's demeanor.
Having a hard finding a connection with stallions, Cadence tried something new and married a mare. Her hope had once again risen when she found out that Fluttershy was pregnant. The twins were the saving grace of the empire. Named for the hope they returned to their homeland, the daughter was called Dawn and the son Shining Light, after Shining Armor, the love Cadence had lost.
The rest of the Mane Six remained in Ponyville, in hopes to restore the Twilight Sparkle they knew and loved. Starlight went to live in the Everfree Castle, like most the others, to help build the resistance and assist Princess Silent Night in her efforts to restore Equestria to its former glory.
Silent Night worked hard planning. Sometimes, at night, she'd seek help from Aura and Jay, the daughters of Starlight and Trixie. It is quite difficult to write proclamations for a new kingdom when you can't see to write.
In her free time, Jay had been working hard on a spell. A spell which could bring new light to Silent Night. She wanted to assist Equestria's future queen by taking the efficiency of her efforts to the next level.
Now, let's explore how this particular day began...the day Silent Night became the savior of her subjects.
"Being adventurous like Uncle Shining today?" Twilight asked her daughter, speaking in a voice she did to both her fillies when they were foals. Out of instinct, she stroked her daughter's mane.
Smacking her mother's hoof away, Silent Night replied, "No mother. Adventuring applies I'm coming back. I'm leaving."
Twilight became enraged. "Leaving?! How dare you disobey my orders?!"
Silent continued walking. "You never told me I couldn't leave you to your own despicable devices." Silent reached the door. "Goodbye mother!" she said as she slammed the door behind her. To her demise, it missed her mother's face, but this was the least of her worries. She was going to overthrow her mother, and it was going to happen tonight.
Silent sighed. "Equestria needs me to do this...I need to make it to the castle." Panting, she found where the castle used to stand. "W...Where is it?"
Silent legs shook from underneath her. Not only had she spent her whole day gathering supplies, while trying to stay one step ahead of her mother, but she had to navigate the forest as well. She looked to the sky, "How am I going to make it through this?"
That was when she came. "Do not fear, child. Your efforts will succeed."
Startled, Silent gazed around herself, attempting to locate the source of the voice. "Who are you?" Silent finally gazed up towards the luminous moon. " Princess Luna?"
"Indeed. Starlight Glimmer was a very intelligent mare to execute this spell. For all your mother knows, this island fell into the sea long ago" Silent watched as Luna used what little magic she had left to lift the spell, revealing the castle.
"Starlight Glimmer was smart to use this spell. To your mother's knowledge, the small island that once stood here is part of the river now."
Silent chuckled. "She's not as sharp as she used to be."
"I will agree. If she was anything like who she was when I wed her, Equestria would not be this way."
"So...is that why you're here?" Silent asked, attempting to ask her questions as politely as possible.
"No, my young one, I'm here for you. You needed help."
"Yes...thank you for everything!" Silent blinked. "Mother?"
Fading cautiously walked into the city, watching the invisibility spell reform behind her.
"S...Silent?"
A familiar voice called from behind her. "Silent Night?"
"Bluejay?" She said, turning around. She felt her eyes water up as she saw someone very important to her.
Her first crush.
Jay glomped Silent, almost as hard as another special day the two had endured, which is a story for another time. Jay held Silent in her embrace for what seemed to be hours.
Cosmic walked up to see what the commotion was all about. "Jay please tell me that's..." She cut herself off at the sight of Silent. "That's not who I thought that was..." Cosmic walked away slowly, which led into a run.
"Say a word to anyone Cosmia, and you'll regret it." Bluejay seemed intimidating to some ponies. Silent was not one of them.
Bluejay gave Silent one look, and knew exactly what she'd came for. "I know that look in your eyes. You have a plan."
Silent nodded. "So...I was thinking..."
