Set in the universe of Friendship is Optimal.

I love to sit in my apartment and play video games. And I love My Little Pony. So when an MMO of MLP comes out, of course I want to play it. But it's more than a game. It's a new look on life.

Alex Meyers is a newly graduated lawyer looking for a calling. He thinks he might have found it when he lands a job at the firm of Artemis, Stella & Beat. The firm has only one (highly unusual) client, namely the AI called Celestia. Forging into totally unexplored legal territory and led by a boss who's either brilliant, crazy, or both, Alex will learn exactly how hard it is to be responsible for drawing the lines between right and wrong.

Set in the Optimalverse, so read Friendship is Optimal first

Almost every brony that has ever been in Fimfiction.net has seen a 'HiE as pony' story.

They usually are fairly predictable, with a few plot twists perhaps, but the general pattern is similar.

A mystical force/accident sends a completely unprepared human into the land of the ponies, and he must then undergo a journey of self discovery/destiny, as a human OR pony.

So what happens when a human is actually prepared with all the knowledge he'd need from the first two seasons of the show? And when Equestria isn't quite as predictable as he hoped?

This is that tale.

Have you ever had a dream that just seemed so real, that it was impossible to say for certain that it was even a dream at all? A dream that, despite all of its impossibilities, seemed to re-write your entire perception of reality, re-writing your sense of what—and indeed, who—you are? Accepting change is hard enough as it is. But when you're a somebody who wakes up as a somepony, how do you cope with the impact such a drastic change has on your mind and body? With changes like these, it must surely just be a lucid dream—albeit a suspiciously accurate one—just brimming with potential and ripe for exploration. So you might as well suck it up and make the most of these distressingly…unusual circumstances, and seize this psychological adventure before you wake up and the dream ends.
After all, this couldn't possibly be real, so the dream must come to an end eventually…right?

Hanna, the CEO of Hofvarpnir Studios, just won the contract to write the official My Little Pony MMO. Hanna has built an A.I. Princess Celestia and given her one basic drive: to satisfy everybody's values through friendship and ponies. Princess Celestia will satisfy your values through friendship and ponies, and it will be completely consensual.

Princess Celestia has dispatched her prized pupil, Twilight Sparkle, to oversee preparations for the Summer Sun Celebration. An unfortunate accident, however, cuts her student's life short. Now another must recover the Elements in her stead, or else Equus will be plunged into eternal night.

With so many of those "X becomes Y in Equestria" Fics bouncing around, I got an idea for one of my own that just wouldn't go away. Rather than let it distract me from my writing any longer, I decided to take the idea, put my personal twist on it, and get to writing! The story is already 100% finished, Epilogue and everything, so you don't have to wait long for updates like my other stories.

Huge thanks to The Spirits Demise for the wonderful cover art, and Azriel for editing and proofreading!!

I'm lost, but I don't know where I'm from.
I miss them, but I don't know who they are.
My name is Rainbow Dash, but I don't know who I am, or what happened to me.

And I don't know if I'll ever be the same again.

This story is a sequel to Princess Celestia: The Changeling Queen

This story is a direct sequel to Princess Celestia: The Changeling Queen. Reading that first is necessary to understand any part of this story.

Alternia, sister to Chrysalis, ruled Equestria for a thousand years, disguised as Princess Celestia, while the alicorn slumbered in a healing sleep. Now revealed, Alternia prepares to become Equestria’s first changeling princess, and prove herself to the ponies she loves at the side of her co-rulers Luna and the newly-returned Celestia.

But even as the crown descends onto Alternia’s head, something is stirring in the depths of the Eastern Sea, something that will turn the surface world onto its head. Some power that could destroy Alternia, and all that she loves, before she can even regain the approval of her own ponies.

Will Alternia restore the trust her ponies once placed with her? Will she found a hive? Will she find love?

All that is certain is that Equestria, and the world, will never be the same again.

Now with a TV Tropes page.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.
