I honestly didn't think there'd be much to this medical trial. I'd just have to be the guinea pig for a potential cure to a big bad disease. I figured the worst problem I'd have to deal with is sheer boredom of being in a lab for several weeks. But I soon realized that boredom was going to be the least of my worries...

Not in continuity with my other stories. Just something that popped into my head one day.

Spell Nexus (mentioned only) is from Past Sins, by Pen Stroke

It's been ten years since Princess Twilight Sparkle and her friends took the roles of leaders of Equestria, saving the land from the Windigoes and possible civil war. While it hasn't been perfect, Twilight and the others have been able to maintain the Golden Era of Peace. However, when a specter from the past returns for revenge, Twilight will be put to the test if she, as leader, can protect her home. But will the magic of friendship be enough to win this time?

One lonely night, Starlight decides to release Cozy Glow from her stony prison, and plans to let out some of her frustrations on the vile filly until she discovers that Cozy Glow can't seem to remember who she is anymore, or much of anything else from her past.

Could this be yet another trick conjured up by this scheming pegasus? Can she really be trusted?

This story is a sequel to Convergence

Equestria was just a game, one of an endless number of semi-illicit online games created to take advantage of the ubiquity of cheap augmented reality hardware. But that changed, when for no reason anyone knows, the virtual population of Equestria woke up.

Two decades have gone by since then, and the world has been transformed. The former game network has grown to encompass the backbone of trade, infrastructure, and research the western world over. Its vast computational resources have given rise to an infinitely subdivided world of overlays and sublayers, coterminous with the various cities and towns within Equestria. Every person in the modern world is assigned a Synth, a pony personal assistant that adapts to their needs and helps them access those parts of the world governed by Equestria's systems.

It is a world Dakota barely remembers, thanks to an automobile accident that turned most of her body to mush. But thanks to the medical miracles created by joint equestrian-human research, her life is saved by a remarkably new series of implants.

But Dakota isn't content to sit around while her body slowly knits itself together. There are unanswered questions to answer, questions that will ultimately lead her to the oldest mystery of both worlds.

Updates every Saturday.

This story takes place during the Season Five finale, "The Cutie Re-Mark". As such, there are spoilers ahead.

Starlight Glimmer's plan is working. All she has to do is upset Rainbow Dash's rainboom-creating race in the past, and Twilight Sparkle's connection with her friends will be severed. And she's done it. Repeatedly. Sure, Twilight can go back in time to try and stop her, but Starlight will always be brought back as well. No matter what Twilight tries, no matter how many times she returns, she can't stop Starlight. They're evenly-matched, and it's much easier to disrupt events than it is to preserve them.

That means Starlight wins, right?

Castling is a special move in chess involving one of the player’s rooks and the player’s king. The move consists of moving the king two squares towards a rook on the player's first rank, then moving the rook to the square over which the king crossed. After this move, the king and the rook end up just next to one another.

And thanks to a friend’s kindness, a certain calculating, chess master filly would have a chance to end up closer to her princess than she ever thought. But can a filly like her truly leave her past behind to find another way? Can you learn to trust another when manipulation is your destiny?
Can a chess player like Cozy Glow learn to be a pawn?

I am Spur. I'm a fourteen year old teenage filly who lives on the bayou with my Ma and Pa. Most of you know me because of my little sister.

My little sister was Cozy Glow. One of the most reviled villains in Equestrian history.

Some praise for My Sister, Cozy Glow:

I had just finished watching the finale, which killed my incentive to write, but upon reading this, I'm glad to say that it brought it back. Thank you for writing this, MicahDebrink. --IReadYouWrite

Man, there's so much emotional depth packed into each and every word. --Thought Prism

This fic is far outside my usual fare but I am still enjoying it immensely. --SockPuppet

Probably the best thing to happen in Discord's long life was finding the magic of friendship. As much as the old Chaos Lord might complain, without it he would never have found so many that were dear to his heart.

When that heart finds itself empty, he comes to the Princess to ask a favor: allow him the opportunity to bring friendship to other dark hearts. All she has to do is lend him a statue.

The rest is in his chaotic claws.
