After the Changeling invasion, Celestia and Luna make the decision to have Twilight investigate the Elements of Harmony and solve the mystery of their power.

A thousand years later, Rainbow Dash awakens in a world she does not recognize. She has no idea how or why she came to be there. She does not know the language, the geography or any of the rules of this new time. She soon finds allies in Star Fall, a scholarly pegasus whose Talent is Magic, and Astrid, Star Fall's Griffin guardian. Together they set out to discover why Dash has been sent to the future, and how she might return to when she belongs.

War threatens the nations, a Nightmare stalks the shadows, and Rainbow Dash's arrival has turned her into a wild card in a deadly game that pits the law on both sides of a broken Equestria against a mysterious criminal figure, Max Cash. Yet the stakes are higher than anyone knows, for in her research Twilight Sparkle discovered a dark secret about the Elements, something that will shake the foundations of the world.

Every day Celestia shares light and love with all the ponies of Equestria. In turn, they share their love with her. Still, the princess senses there is something missing. Something her heart longs for.

Something her responsibilities have denied her for all these years.

As luck would have it, she’s given a gift that will let her experience her deepest hearts desires and take her to a place she may never want to leave.

Ever.

Inspired by the Alan Moore story, For the Man Who Has Everything.

When Celestia went on sabbatical into the west, she promised Twilight it would be only a couple of months. A year and a half later, the sun resists control, the country is in ruins, and her teacher is lost in the wilds. Twilight has become the apostate, her faith in her teacher and her teachings waning. In the wake of tragedy, her resentment blossoms into fury and she vows that something must be done. Shadows gather around Canterlot, and old things that should not have been awakened are on the move. The Student goes west, her hope restored by friendship and righteous fury.

The night, at long last, is passing.

How does one start a revolution?
For Evenstar Boral, the question was always an academic one, suitable for late night conversations and maybe an article in the university newspaper.
Now she's getting a little more field experience than she'd like.
With strange ponies recognizing her on the street and her best friend plagued by nightmares, Evenstar finds herself thrust into events seven thousand years in the making. What is the strange symbol that keeps cropping up in her life? How can someone she's never met know so much about her? And who was Twilight Sparkle?
But there is still hope, for even in a world of shadow and fear, true friendships never fade.

The wheel of time turns, as destiny and history clash together.

Fifty years into the future, Sunset Shimmer is Princess Twilight Sparkle's most faithful student. She is smart and eager, but doesn't always think things through. Her life had been perfect, right up to the End of the World.

With a ruined future, Sunset travels into the past to alter the course of history. With only her mentor's cryptic word to go on, Sunset and the Elements of Harmony must solve the riddle of the Dark Regalia and stop the mysterious Vesper Radiance from rising to power. But the further Sunset goes, the more she feels like she's been through it all before.

Is destiny set in stone, or can Sunset shape her own future? Only time will tell.
