Words and actions can sometimes hurt more than we know, sowing betrayal and hatred where friendship and innocence lies. A single thoughtless action can be a tipping point, one fallen domino setting off hundreds. Look back, and answer me.

For almost a thousand years, the immortal Nightmare Moon has reigned over Equestria as Empress. To the average pony, Nightmare Moon is an overarching enigma whose rule is absolute and whose wrath is terrible. But to Twilight Sparkle, who as an orphan has never known her parents, the Empress is something else entirely. When the young unicorn is brought under the royal wing as an apprentice, she learns a great deal more about the supposed tyrant than she ever knew. But as Twilight is introduced to life with her new mentor, she is thrust into a world of political intrigue, conspiracies and secrets. Secrets that were never meant to be revealed. As allies and enemies plot against the very peace of the nation, will Twilight fall prey to the perils of her new position? Or will she prosper and find in Nightmare Moon the mother she never had?

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.

This story is a sequel to Under A Luminous Sky

In the wake of the Mbwun killings , Spike seems to be better off then he was before: his large, muscled body is a far cry from the chubby baby he was, and he no longer has to go through his hundred-year wyrm sleep. Life, however, is rarely so simple. As he and Twilight move back to Canterlot, Spike finds that his new body may very well mean the end of his old life.

This story is a sequel to Past Sins

Hearth's Warming is a time for friends and family to come together, celebrate harmony, and welcome the new year. Nyx is looking forward to just this as she rides the train to Canterlot with Spike and Twilight. She's going to meet her extended family for the first time and wants nothing more than to make a good impression. Yet, the sheen of the holidays can't hide the trouble caused by meddling grandparents, relentless reporters, and a paranoid uncle.

The two-part series pilot "Friendship is Magic", but with a Kingdom Hearts twist. Aspiring Keyblade master Twilight Sparkle fails her attempt at the Mark of Mastery exam. To help get her mind off her studies, Princess Celestia sends Twilight to the nearby town of Ponyville to oversee preparations for this year's Summer Sun Celebration. But the threat of a great 1,000-year-old evil looms.

(Gasp! A Kingdom Hearts crossover! It's so original! ...Yeah, I know it's been done countless times already, but I just couldn't say no. I love Kingdom Hearts; I'm not exaggerating when I say it's the only thing I love more than MLP. 'Blasphemy! Burn the heretic!' I can already hear some of you thinking. Again, I thought the opportunity was too good to pass up. And so here we are.

Fair warning: if you haven't played any of the Kingdom Hearts titles, much of this story will likely go over your head; only the bare minimum of accessibility will be given to series newcomers. Secondly, as this is a Kingdom Hearts take on the "Friendship is Magic" two-parter, Sora, Donald, Goofy, and other KH characters will NOT be appearing. I feel I should make that clear so I don't end up disappointing those of you hoping to see your favorite KH characters as ponies.

Also, if this turns out to be popular, I may do Kingdom Hearts versions of other MLP episodes and even some completely original stories.)
