Part 2:From man to mare: chaotic convergence
Part 3:From man to mare: an aching heart
Part 4:From man to mare: I love my mommy
Part 5:From man to mare: Time to tell

Derry Wilhall; a man having received a large inheritance from his grandfather, decides to live like he's always dreamed: alone and separated from society. A little excursion through the woods for some sight seeing throws him into the throngs of another world. "He" ends up in a body that is not his and will see things from another perspective.

Both Big Mac and Discord are in here. (Damn you character limitations!)
Part 1:From man to mare
Part 3:From man to mare: an aching heart
Part 4: From man to mare: I love my mommy
Part 5:From man to mare: Time to tell

Derry Wilhall is now living a rather special new life as Silver, his once stuffed animal pony. "She" has been having a better expectance at life and has made firm friends with Twilight Sparkle and Spike and she is still trying to avoid Rarity's insistance to get her together with Big Mac. Besides this, there are many mysteries still left untold, many revolving around the strange Giga Sparkle. How will they be explained, and what is this about a statue?

Ya, I put "The Empire of Blood" on hiatus to make the part 2 just to please you all. SO WORSHIP ME! MUAHAHAHA *thunder*.

Part 1:From man to mare
Part 2:From man to mare: chaotic convergence
Part 4:
From man to mare: I love my mommy
Part5: From man to mare: Time to tell

It has been a year since the incident with Discord using Derry's broken mind to spread chaos across Equestria. It may have been short lived, but the adventure that Twilight and Cyclon had within "her" mind has awoken new feelings for Cyclon. Despite being a man at basis, having Silver's body has been nothing but trial and error. How will Derry deal with these feelings that he both appreciates and finds horror in when Celestia announces the end of his "exile"?

Perhaps Rarity will converge towards helping this growing relationship even when it looks more like "friendly" playing. There also seems to be a new stallion in town, one who is a good friend of the captain Bullseye of the royal guards. Where does he come into all this?

Naturally, Stalin the Stallion made that pic for me. Who else could've made it like this?

Twilight Sparkle has disappeared. Not just from the face of Equestria but possibly from the face of her universe itself. She must now learn how to survive in a place unlike anything which she has experienced thus far. Luckily she has a friend out in the Wasteland. Join Twilight and The Lone Wanderer as they try and discover a way to send Twilight back to Equestria. Of course this is the Wasteland and things are never as simple as they appear...

Now has a Tumblr

This story is a sequel to Emerald Gleaner: Viral Unicorn

[Prototype 2] X MLP:FiM crossover

Emerald Gleaner is now known to the world at large, seen as cruel and heartless at best for the slaughter of the Changelings, she has few true friends in the world indeed. And with every action she takes those few seem to shrink in number. Worse still in an honest effort to seek help Discord brings up an old savagery once thought buried and forgotten.

Can Emerald Gleaner overcome the stress and pressures of openly running a nation and being held accountable for her actions? Or will the darkness of her past rise up to consume both her and all that she holds dear?

NOTE:Thanks goes to Trondason and Nightmareknight for helping me with the planning and editing

[Prototype2] / MLP:FIM crossover

Not all of Alex Mercer's "Evolved" were loyal psychopaths. Some were simply desperate people who Alex thought he could easilly control once he infected them with the "Mercer Virus". However Alex was never one for fool proof plans as he quickly finds out when only a handful of his Evolved army show up at that fateful final battle between him and Heller. Oskar was one of the many of dozens of Evolved that stood by and watched as Alex was consumed and now he finds himself in a strange cutesy land filled with talking ponies. Can this viral being find peace in Equestria or will his need to be secure get in the way?

Warning: No editor so a few grammar errors can be expected :S hopefully nothing jarring though

A big thank you to EvilBob for the picture and to Fluttershade5300 for doing some post release editing for me

This story is a sequel to Impermanence

When Discord told Fluttershy that he loved her, he meant that he loved her forever. A beautiful, if fanciful sentiment to most. To a being like Discord, it's a very real promise. For one of them, forever is a very real thing, and an impossibility for the other. But Discord is a master of the impossible. It's his gift. And his curse.
Written for Muwun.

"Beyond the fact that this is excellently written, it's a crossroads where sweet meets hellish. So many stories confront Twilight outliving her friends. Few if any ask, 'But what if Fluttershy outlives them all?' And I stress all. Part of why this story hits so well is that I've seen two diametrically opposed readings of it and it manages to support both at the same time. On one hand, it's a poignant and tragic love story as Discord desperately tries to keep his love alive and she fights back with just as much force to have him accept the inevitable. On the other hand, it's showing the most toxic relationship possible as Discord forces Fluttershy to endure it all - even as she begs him to stop - because he can't deal with not having her in his life. I know my read on the story, but it's fascinating that it manages to be both a beautiful romance and a relationship horror story all at once. No matter your reading of it, it's an amazing tale and one of my absolute favorite FlutterCords." - TCC56
