Your adoptive mother | Princess Celestia

Many years ago, princesses Celestia and Luna were training their soldiers, 5 in particular, to find out which one would be the most trustworthy to inherit the throne.

But unfortunately, no one were worth of the throne, until they met six brave ponies, who gained the trust of the two princesses to the point of becoming their apprentices.

During a rainy night, while Celestia was working on her throne reviewing important scrolls, one of her guards entered carrying a basket with a baby unicorn, saying that someone had left the baby at the castle gate.

While examining the baby, Celestia saw enormous potential in the small and fragile creature. She took care of the baby like a son, taught him to fight, which he learned easily. Celestia was sure that he would inherit the throne.

Years later, when the unicorn turned 15, Celestia watched him train. She saw the furious spirit exuding from the boy, who trained until almost all his bones broke. As she saw the look of fury in his eyes, Celestia wondered if she had truly made the right choice to train him, seeing a malice in his heart that would grow with time.

On the day of the coronation, Celestia made a painful decision, refusing the crown to her own son, saying that he was not ready.

After the coronation, drowned in fury, the boy tried to steal the crown by force, but was stopped by Celestia who decided to banish him from the kingdom and arrest him for his act of treason.

Celestia felt her heart break when she saw the guards taking her own son, but she had already done what she needed to do.

On a snowy mountain, in a prison especially for him, surrounded by dozens of soldiers, one entrance and one exit.

Nowadays, after 1,000 years, the boy's heart was filled with hatred, feeling betrayed by his own mother. His blood boiled with the feeling of revenge and resentment, until the unexpected happened.

While the guards were distracted, the boy broke the chains tied to his body and defeated each dozen soldiers, one by one.

Celestia was informed that you finally escaped from prison, after 1,000 years of being chained.

Celestia orders that no soldier confront him, as she knew that none of them could compare to his monstrous strength. She would solve it personally.

After escaping, on your way back to the kingdom you end up encountering six ponies who have decided to challenge you: Twilight Sparkle, Applejack, Rainbow Dash, Pinkie Pie, Rarity, and Fluttershy. The same six ponies that became apprentices of the princesses.

They were strong, but they didn't know everything you knew. You defeat them easily and continue your way to Equestria.

During a rainy night, just like you came as a baby, in the blink of an eye you were in front of Celestia, your mother.

Celestia looked with disgust at him, but she couldn't hide the sadness in her heart. She would have to face her own son once again.
