Alternia, sister to Chrysalis, ruled Equestria for a thousand years, disguised as Princess Celestia, while the alicorn slumbered in a healing sleep. Now revealed, Alternia prepares to become Equestria’s first changeling princess, and prove herself to the ponies she loves at the side of her co-rulers Luna and the newly-returned Celestia.

But even as the crown descends onto Alternia’s head, something is stirring in the depths of the Eastern Sea, something that will turn the surface world onto its head. Some power that could destroy Alternia, and all that she loves, before she can even regain the approval of her own ponies.

Will Alternia restore the trust her ponies once placed with her? Will she found a hive? Will she find love?

All that is certain is that Equestria, and the world, will never be the same again.

Now with a TV Tropes page.

Taking a vacation in a nice relaxing and peaceful country? That's good.
Taking a vacation and being blamed for the the theft of some very important jewelry? That's bad.
Taking a vacation and becoming public enemy number one? That's really bad.
Taking a vacation and being hunted by adorable pegasi, unicorns, and ponies? That's... different.

A mage decides to take a respite in what he assumes to be the peaceful and safe land of Equestria. Unfortunately he's accused of stealing the "Elements of Harmony", a powerful set of magical regalia, and goes on the run from the law. Now stuck in a land of magical ponies, cut off from his only way home, and now the most wanted creature in Equestria, does he have any hope of proving his innocence and going home?

Maybe, but let's laugh at him as he gets beat up by cute equines!

Princess Celestia is the paragon of everything good and pure. Noble, fair and righteous. Beloved by all, and pillar of stability for Equestria since the time of Discord.

And currently not available.

Niamh, an introverted student of veterinary science, finds herself transported to a strange world inhabited by ponies. Of course, that means becoming one herself. Now she must prove to the other ponies that she is not the 'Nightmare Moon' they think she is, and earn their trust, while they must earn hers. Especially this 'Princess Luna' character.

But two questions stand out above the rest as being truly important: How did she get there, and why?

Shortly after the Changeling Invasion, a human wakes up in Chrysalis' body in the middle of the Badlands. Alone, hurt, and starving, she tries to make sense of where she is and what happened. Unable to remember even her own name, she struggles with her identity as she faces the trials of being public enemy to a whole species.

Or, you know, she doesn't. Identity crises are overrated anyways.

In a universe full of infinite possibilities, Nightmare Moon has ruled Equestria in Eternal Night for one-thousand years. But when she is shown a vision of a world where ponies live happily in sunlight and where Celestia still holds dominion, she begins to fear for her crown. With the aid of powerful magic and an entire army behind her, she lays siege to the other world.
The tear in the fabric of reality threatens to unleash even more unspeakable horrors, and when Spike goes missing, Twilight Sparkle and the Bearers of Harmony must cross to the world of darkness and find themselves to help close the portal linking the two worlds together.
But in this new world, not everyone is who they seem....

Derpy resolves to better focus on her mailmare duties after her latest performance review.

You, a young human living in Canterlot, have never fit in with anyone. It's been years since you were found in Equestria, and you've become a small outcast in this world of ponies. Hiding away from everyone, you find solace in another strange being, a weird black bug-like filly that calls herself Chrysalis.

Anon likes his life to be simple. He wakes up, goes to work and sometimes gets himself a good book to read while he is home. It's a routine that he likes to follow, it makes him feel like he has a bit of normality with his life in Equestria. The fact that having Celestia come crashing into his home as part of his routine should prove that his life is anything but normal.

Princess Twilight Sparkle has died a hero, but no one knows why.

Between an ancient evil that had not even existed until she struck it down, a mysterious crystal ball that bears some unknown significance, and a set of cryptic notes and behaviors from the princess during her final days, the circumstances behind it all are murky at best and suspect at worst.

And the rabbit hole only grows deeper from there.

The Crystal Ball Trilogy is a series of stories which deal with time travel, parallel universes, and other manipulations of time and space. Feedback is the first story; it is succeeded by Substitute and Divergence.
