Have you ever seen a pony that just seemed out of place? Perhaps some mannerism, some behaviour that just struck you as odd? Some piece of clothing that didn't seem quite right? perhaps a coat or mane whose colour just seemed flat-out weird. A strange build, a strange voice, or maybe they were perfectly normal, except that you swear you just saw the exact same pony not five seconds ago somewhere completely different?

Of course you have. Everypony has encountered an Outsider at some point. But never up close, it's always at a distance, and they're always gone before you have the chance to challenge them.

But sometimes the rules get broken. Sometimes fate gets distracted for a moment, and a lone unicorn mare gets to see something that she was never meant to see.

Twilight Sparkle's day is about to get very weird.

Thanks also go to my editors for putting up with my atrocious grammar and spelling errors - Ganelon, Ephraim Blue, BronyWhooves, Commonancestry, Princess Autumn Forest, and Morning Sun

Cover art credit goes to EMedina13 and tamalesyatole. I am looking for more appropriate art, so If you think you can do better, let me know.

A young girl, having been robbed of her childhood and very life by illness finds herself given a second chance in a strange world and with an even stranger body. With a new life, family, and even a brother, she tries to cope with the bizarre world she's found herself in while also trying to embrace her role and become worthy of the gift she has been given.
Being a princess can be hard however, even if it's only an honorary title, especially when you're the twin sister of Prince Blueblood.

Warning, very slow burn.

With the nightmares of the Silos behind them, Astral and Sassi begin to adapt to a world that lacks any understanding of the horrors now buried underneath glass and stone. The only creature in their life who can serve as a confidant is Arcane. However, the chaos-unicorn is busy learning to adapt to a world and society now alien to him. But they have each other, and their lives start to settle into a form of pleasant normality.

As life in Equestria and the Gryphon Empire continues on, Twilight and Tanzil are forced to confront troubles both within and outside their borders. Sometimes peace is but a thin, false veneer over chaos, and the two rulers quickly discover that their budding relationship may be the least of their troubles.

When a familiar horror emerges from the shadows, Astral, Sassi, and Arcane are forced to confront a terrorthat looms not only to engulf their new home, but all of Equestria and beyond. With their nightmares no longer confined to their minds, the three ponies desperately try to save who they can from the oncoming storm. When faced with some threats, all you can do is run and pray that it doesn't find you.

But for the two Thestrals, a unicorn, and their friends, they're sick of running. And they've got lots, and lots of ammunition.

In every event, there are a million offshoots and effects, none really able to be fit into a normal narrative. Here is a collection of one-shots and mini-arcs spun out of The Elements of Harmony and the Savior of Worlds, so knowledge of that series will help immensely. Although I will do my best to make it as accessible as possible.

NOTE!:
All side-stories so far take place after the end of The Elements of Harmony and the Savior of Worlds.
The cast will be varied, as will be the stories, but all are canon.

Chapter One: A Picnic by the Lake: Celestia, Luna and Twilight entertain a guest who is more than meets the eye.
Chapter Two: Time Enough for All: The Doctor has spent nearly nine hundred years in Equestria, most it an extended vacation. But news of giants in Ponyville draw him out of semi-retirement.
Chapter Three: Contact Part One: Old Memories: Chip delivers the Princess' message to President Abernathy, which stirs old memories.
Chapter Four: Contact Part Two: Meetings and Greetings: Equestria makes formal contact with Earth, and an old mystery is finally put to rest.
Chapter Five: Family reunion Part One: The Best of intentions: Dinky sets out to reunite her father with his closest friends, roping her sister and the rest of the Cutie Mark Crusaders on a journey across time and space.
Chapter Six: Family Reunion Part Two: Memories: The TARDIS arrives at Earth, reuniting the Doctor with his past.
Chapter Seven: Shape up or Slaughter Out!: Shining Armor gets some help from an old warhorse to finish what he started with the Royal Guard.
Chapter Eight: How Christmas was Saved... Sort of: A short tale of how Santa Claus was saved one Christmas Or Megan had too much eggnog.
