This story is a sequel to The Mane Six Regret Playing Truth or Dare

Months ago, the Mane Six played their first round of Truth or Dare. As a result, they ended up having a rap battle, learned about secret crushes, and managed to start a beautiful relationship between one of the Mane Six and a Wonderbolt. Since their first game, Starlight Glimmer and Spike joined the fun. This week is the same as always. But little do they know, two unexpected guests come to play.
The rules are simple.
1. If choosing Truth, you must tell the truth when some pony asks you a question.
2. If choosing Dare, you must perform the dare some pony dares you to do.
3. You cannot change your choice once you have selected something to perform.
4. You cannot choose somepony to dare you to perform something or ask you something.
5. The game ends at midnight when Princess Celestia and Princess Luna say it ends.

It's recommended to read What Happens at the Lit Club... and The Mane Six Regret Playing Truth or Dare if you want to understand some stuff that's going on.

Sunset Shimmer is coming back to Equestria. Unbeknownst to her, Twilight Sparkle has a new pupil, one that she hopes she'll become fast friends with.

Unfortunately, Starlight and Sunset have a better idea.

A collab with the amazing Flutterpriest. You should definitely go check out his other work, he's amazing!

Take this story seriously at your own risk.

Even for ponies such as Twilight Sparkle, magic is something that's both easily understood, yet full of unknowns at the same time. Wondering about the mysteries surrounding magic and its relationship with Equestria as a whole after an innocent question, Twilight tries to research whatever she can about the subject.

However, there is something ominous brewing in a distant land that may relate to Twilight's questions about magic, but solving some of those mysteries will require more than just research. She'll have to overcome her most dangerous challenge yet in order to uncover the truth.

What if the torturous, but victorious feeling of discrimination could segregate even the most joyous of families?
Starry Night was born on a cold day in the middle of winter. She seemed to be perfect! Beautiful, wavy mane, beautiful blue eyes, the sweetest smile. Twilight's family is put between a rock and a hard place as they discover that their newest family member is not a unicorn, but an earth pony. A simple earth pony in the family of gifted unicorns would not do! With that, they decided to drop Starry Night on the steps of an orphanage, and never speak her name once more. Bur soon, Starry Night learns about the power of friendship as her sister does, and she soon realizes that friendship, is more important than your past.

On a day of remembrance, a new threat arises, shedding light on old mysteries.

This follows Two Pair by about 700 years, but is not a very similar story, and reading Two Pair is not necessary to understand Sparkle Day.

Princess Celestia had a good day. Luna had been going out more often and was becoming quite fond of nightclubs, her dear niece Cadance had formally announced her pregnancy—though, privately, Celestia felt she was too young to be a great aunt—and, of course, Twilight, her beloved former student, had taken on her first student and Celestia couldn't be prouder! Yes, it had been a good day.

Celestia Sol woke up much like she did every day the morning: sun waking her as it danced upon her eye lids. Wait, the sun? Celestia's eyes snapped open to reveal she was in Twilight's old room in the observatory. On the other side of the room was a smaller bed where a small dusky unicorn was drooling on her pillow.

Clearly, it must be Tuesday.

It's just been a few days since the friendship games, but something drastic has changed. The solar system of Earth isn't what the inhabitants of the planet are used to. Plus there are two teenage, high-school students, who control the most important objects in the sky.

A few days after the Nightmare Moon Incident, Spike awakens to find Twilight acting a little...odd. Or odder than usual anyway. All of a sudden she's being all motherly, sure of herself in ways she's never been before, and even more outgoing.

But…it’s kind of creepy how she just seems to know everypony’s name, or their habits, and even some stuff nopony else should know.

But she's still good old Twilight...right?

Mistakes.
Everybody makes them.
Not all mistakes are equal.
Some are far less costly than others, and some can spell disaster.
When mistakes have such disastrous effects that you know it was not meant to be this way, you try to fix them.
When alicorns make mistakes, the fate of the entire world can change on a whim.
I am Princess Twilight Sparkle. I know where it went wrong.
I may not be able to undo my mistakes, but I can prevent them from happening to myself again.

Upon her first use of darkness its taste lingered within her mind, creating an ever growing thirst and revealing her true desires. With her recent elevation to an alicorn and princess she begins to find her desire for power insatiable. Small seemingly inconsequential steps grow into giant leaps, pushing her senses of morality and reason.

Besides, doesn't the ends justify the means? For a queen can accomplish so much more than a princess....
