In the aftermath of an "experiment" gone too far, Twilight Sparkle must make an impossible decision: to continue dreaming a lie or to awaken and drown in a nightmare. As a certain group of friends struggle to come to terms with the betrayal from one of their own, they will have to remember the value of friendship, and embark on a struggle to rekindle their inner joy.

Friendship lasts forever.

Right?

Three years ago, Gilda and Rainbow Dash became fast friends at Junior Speedsters' Flight Camp. Time took its toll, though, and the pair drifted apart.

When Gilda tries to reconnect with her not-so-long lost friend, she'll discover that things can change a pony after three years: a new home, new job, and new friends.

This story continues in Summer Days

Stranded on a hostile, alien world, Twilight Sparkle and Rainbow Dash must depend on one another and a fellow alien castaway if they want to return home to Equestria.(originally published on FFN)

In the aftermath of the Changeling invasion, Twilight Sparkle realized the great (and, in retrospect, obvious) flaw of the Elements of Harmony - They may well be Equestria's greatest weapon against evil in the right hooves, but the artifacts themselves are vulnerable.

But what if the power of the Elements could be summoned without the jeweled necklaces, without the tiara? Working off little more then cryptic hints from her mentor, Twilight embarked on a mission, plumbing the depths of the royal archives to rediscover an ancient ritual, one which could concentrate the Elements within their living vessels...a ritual she has finally found.

What's the worst that can happen?

Rainbow Dash unleashes a new stunt she created for the latest Wonderbolts tryout session. Feeling confused about her chances at becoming a professional stunt flyer she returns to Ponyville and await the impending news. But things aren't what she exactly remembers.

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.

No pony is the same after witnessing a work-related death, no matter who they are. The victim was young, eager, fresh-faced, and recently hired. In his last breaths, he let out a scream so heart-rending that the employees who heard it had difficulty sleeping that night. And Rainbow Dash was no exception.

But she's not losing sleep over that. What disturbs her is something far worse—something she said afterwards.

My name is Rainbow Dash and today I learned something new. I learned I'm actually a changeling. You'd think that would be something you would already know. I just learned it now when I saw my true self for the first time. How did I come to replace the real Rainbow Dash, and when? And why can't I remember it?

You'd think that being trapped in stone would mean that, if nothing else, I could get some peace and quiet. Unfortunately, it seems that Celestia has other ideas.

She has appointed these ponies... these 'Keepers', as she calls them, to keep me entertained during my incarceration.

Honestly? I'd prefer the boredom.
