After an unsettling experience with Soarin, and hearing that her friends think she's gay, Rainbow Dash starts to question her sexuality.

When she finds out the truth, will it jeopardize her relationship with Soarin and perhaps her friends?

The "Sex" tag is for language. This is not a story about being gay or not gay, but on uncovering one's identity and coming out.

Twilight becomes alicorn of the stars. This is sort of a problem, because Luna kind of already was alicorn of the stars. Oops!

TV Tropes

Three weeks after the events of Rainbow Rocks, the sirens are desperate. Without their hearts—the jewels that hold their magic—they have no power. They can't sing, can't manipulate people, and worst of all, can't feed. Their only hope is to restore their hearts, and they need to do it soon, before all three of them starve.

The problem is, they're not sure how to fix the hearts. All they've managed to figure out is that they'll need magic to do it, and magic is exactly what they don't have. Scared, starving, and completely out of options, the sirens turn to the last people who would ever want to help them, and the only ones who actually can: the Rainbooms.

Based on Mark Twain's "The Prince and the Pauper."

Twilight Sparkle is stressed with her new role as a princess and wishes she could go back to being a regular old unicorn.

Dawn Cracker, a unicorn living with her indebted father, wishes she had the life of a princess.

When the two meet, they discover they look a great deal alike and (of course) decide to switch places. What chaos will become of this?

After a tragic accident, a human ends up in Lord Tirek's body, as part of an attempt to reform the villain after his recent escapades. While the hero of our tale is trying to make sense of his new surroundings, the rest of Equestria thinks that the most terrible threat that their world has ever seen is back...
And the powers that be are definitely not happy about it.

This story is a sequel to The Assembled Letters of Twilight Sparkle, Protégé of Emperor Discord

After getting a taste of Friendship and questioning her allegiance to Discord, Twilight Sparkle chose instead to accept the will of Chaos and remain a student of the Emperor. Now, she has been charged to return to Ponyville and plant Seeds of Discord around the Tree of Harmony, but there are more things than broken friendships awaiting her arrival in Ponyville.

A note on the [Dark] tag: This fic is not grimdark.

It is however, an adventure story with high stakes, and themes that may touch on more serious matters, such as brainwashing or mental/emotional abuse. There is also some brief moments of violence and intense danger that, while not excessive, may be troubling to some. This tag was actually something recommended by one reader after Discord's psychological games with Twilight in the previous story, and I think it's time to add it. Link to reddit discussion where I made the decision, slight spoilers for Chapter 6.

Please don't let it turn you off from the story, just consider it fair warning that some parts may be slightly disturbing to more sensitive readers.

Twilight Sparkle has spent years as Discord's protege, studying the Magic of Chaos. But when rumors of a strange phenomenon dubbed "Friendship" show up in a small outlying town, the Emperor sends his star student to find out what's going on. Twilight goes with the best intentions and quickly discovers there is more than meets the eye going on in Ponyville...
