While attempting to solve the mystery, Twilight Sparkle has to analyze the tenuous balance between friendship and honesty. She doesn't like what she finds.

It had been a few years since she was forced to leave the vault she called home, now people don't even know her name but the title she was given. A malfunction with a device she was given takes her to a land that is not like her own. How will she handle this new environment and these happy ponies?

Conjuration is a lost art in Equestria. Celestia is bored, and decides to learn some summoning spells. She summons an otherworldy creature, but will it be anything like what she expects? A non adventurous HiE. Mostly just learning about interactions. I'm just gonna roll with it, and add tags an ratings as the story unfolds.

TD Harrison Powell, the human that first came to Equestria in No, I am NOT a Brony, GET ME OUTTA EQUESTRIA!!! has been in Ponyville for about three months when Twilight realizes something interesting: she doesn't really know that much about humans and how they work. Sure TD is receptive to her interviews for the most part, but he can't tell her everything and she wants to find out about how he acts casually.

So she decides to stalk him for science!

This is a little one-shot I decided to make while I'm waiting for my pre-readers to get the next chapter to me. This is canon and isn't supposed to be taken seriously at all.

This story is a sequel to Scion of Chaos

After returning to Ponyville from Canterlot, Sweetie Belle tries her best to find her place amongst friends and family and to remember what it feels like to be home.

This story takes place 4 days after the finale of Scion of Chaos. (I recommend reading that first, if you haven't already)
And set 5 years later is the sequel story: A Heart of Change

Thanks to Rameslack for his amazing cover art.

This story is a sequel to Hard Reset

Her recovery is cut short, though, when a letter arrives informing her that the time loop spell she cast is causing severe damage to space and time itself. In over her head, Twilight tries to summon anypony who will know how to fix it. The pony she gets is the last one she ever thought she would meet... and nothing like she expected him to be.

Princess Luna is the guardian of the dreams of all the ponies in Equestria. She takes great pride and great pleasure in this duty, but when the dreams of Applejack and Rainbow Dash keep forcing themselves upon her, she finds her waking world tinted by the nightly passions of two ponies who can't quite seem to admit to each other what they want.

Amazing dramatic reading here!
Incredibly British dramatic reading here!

Love doesn't always last forever. And sometimes it can crumble so spectacularly that you never want to see or speak to the other person again.

Celestia was perfectly content with that. But when Twilight Sparkle suddenly appears at the palace in Canterlot, after a century of silence, she has no choice but to talk to her.

Politely, of course. Always politely.

*Credit and many thanks go to littlerobotbird for the concept and editing of the cover art. As near as I can tell, the original picture is Jykinturah's work, but the source post seems to be gone.*

The Princesses find an alien creature barely clinging to life at the scene of a terrifying crash. Can the Combined Power of the Elements of Harmony save it, or more importantly, should they save it? Will the arrival of this strange creature tear Equestria apart?
