In Twilight Sparkle's dreams, all her friends are turning on her. The nightmares are steadily driving her mad and preventing her from getting any kind of sleep. The cure may be found in Canterlot, or must Twilight find the solution in her own mind?

I'm labeling this dark because some of it gets a little intense, but there shouldn't be anything too off-putting, unless you're Twilight!.

Twilight has always felt just a little uneasy about how others treat her, but after a tragedy befalls the Sparkle household, she reveals her greatest truth at the funeral.

Can her friends, family, and teacher comfort her this time?

No. 

...but when emotions are high and mistrust and confusion are rampant, is everything what it first appears?

What would happen if Twilight Sparkle was exposed to the corrupting influence of dark magic? This question is answered when Twilight finds a spellbook in an old library in the Crystal Empire palace. The spells within begin to corrupt Twilight with the want of knowledge. Can she resist?

[I only know so much about the OC Twivine.This is the one who created her. Rating will either change to M or the next installment will be an M story. Tags added as I need them.]

Emerald Morrison didn't have the best life, but certainly not the worst. She didn't have the best grades, but also not the worst. But now? Now she finds herself as Twivine, an OC made by another brony. Problem is, she has no idea who Twivine is. She heard of Twivine, seen one or two fan made pictures but that's about it.

Somehow Twilight's magic surge brought Emerald or rather Twivine to Equestria and now she grows up (again), only this time in the Sparkle household.

Twilight is now gone, her friends and family are devastated. Twilight must now have to find a way back. She has to. Doesn't she?

Special Thanks:
Thanks to Stormy Venture for all the help!
Thanks to The Myth for the plot!

Lists are a simple way to keep yourself productive. If the list is detailed enough, you don't have to even think. The movements become mechanical. Automatic. Which might just be exactly what she needs right now.

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.

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.

Equestria is a land of magic and harmony, a peaceful realm ruled by immortal and benevolent monarchs. At what cost is this possible?

Following the discovery of a strange and powerful device, Twilight Sparkle is whisked away to the edges of a land she thought she knew so well. Here, surrounded by ponies whose very existences have been kept secret, she must contend with vicious enemies, hostile allies, and the truth.
