When their fates become intertwined, Tinker will travel through time and space with the pony once known as Twilight Sparkle and witness the nature of her universe and the ponies who inhabit it.

Haunted by memories of her past, The Great and Powerful Trixie returns to the scene of her greatest defeat. Will she find a new path in life, or will the past make that impossible?

A Twilight Sparkle / Trixie story, originally published in April of 2011. It is presented here untouched, without being updated to match canon.

Luna discovers something hidden from Celestia for twenty years, now, with emotions running high, she enlists the help of the Mane 6... but what seemed to be a single mystery, soon reveals a darker and much more complicated plot that will soon decide the fate of Equestria.

Should you form attachments to mortals if you yourself will never die?

Losing the last of her friends in a battle that should never have been fought, Twilight Sparkle's world falls apart, until meaning and purpose come back into her life in the most wonderful way imaginable. But she forgets, again, that every living creature must eventually die...

Sequel to Not My Destiny, which you can read here. PG-13 for some mild psychological horror and plot-relevant, non-gratuitous injuries. I'll try to keep to the same chapter-a-day release schedule as I did back over New Year's.

Glorious cover art: Secreta Altare Window 3: Twilight Transcendent used with the kind permission of the magnificent confused--guy!

And learns that she's a far more important little pony than she ever imagined - for all the wrong reasons.

Thanks, man!

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

Eventually, Rarity can take no more of this, and begins reporting back to Celestia in secret while delving deep into a world she had no idea was so intertwined with her life's goal.

This story is a sequel to Upheaval: Breaking Point

Following the events of Breaking Point, Twilight Sparkle and her friends discover that Equestria's demise may not come from an enemy invasion, but from within. The Barrier Lands and the Heartland begin the slow and uneasy process of reuniting into a single Equestria, but this long-delayed joining is already in danger at its conception.

With Celestia's power in her grasp and her agents by her side, the wheels of Black Rose's plans for Equestria's future continue to turn. However, her brazen gamble has done more than just bring down a centuries-old barrier. Ancient powers begin to stir: the remnants of a dark period in Equestria's history, the immortal inhabitants of Celestia's homeworld, and a rising tide of darkness coming ever closer.
