Hope is the faith of the young. Losing everything she holds dear, Puppysmiles embarks on the adventure of her life to find her mother, her hopes of meeting her again driving her through the horrors of a world not of her making. Too bad the Wastelands doesn't care about hope.

Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

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.

I was still a young colt when I took my first steps into the world of steam engines and railroading. I was meant to sing the song of steel, the chorus of the railways. Despite the challenges, discomfort, and dangers, I wanted to be a railway pony. I wanted a fine steam engine like #3803. I wanted to be like Highball.

What I got? Well now, there's a story worth telling...

When a spell goes wrong, Twilight finds herself and her friends... as stallions! Will they be able to reverse the effects and return to their normal lives?

In a freak accident from the Cloudsdale weather control team, Twilight is struck down by an errant lightning bolt. But the veil of death is relatively thin...

Twilight Sparkle wakes up one morning to a harsh dose of unreality. She is stranded, without her friends, on an island which matches no known locale on Equestria. Surrounded and harried on all sides by the alien and the dangerous, she will find her mettle sorely tested, and find perhaps that the best friends you will ever have in your life are the ones you make when your back is to the wall...

Thanks to CedricBale and noobie56xx for tracking down the name of the artist so I could give them credit.

The changelings are banished, the day is saved! Yet a victory for one must be a defeat for another, and this particular victory has left one changeling stranded in Canterlot, alone and broken. A certain pink party pony is also alone in the Canterlot night, hiding her depression from her friends. She cannot, however, hide her feelings from a changeling. What will become of this unlikely pair?

Bored one evening, Discord suggests to Celestia that they spice things up by seeing who's best at doing the other's job: he'll handle keeping things harmonious, and she'll be there to throw a big ol' spoonful of chaos into the mix whenever she feels like it. To his surprise, she agrees to do it. He's certain he's got this one in the bag—after all, how hard can something as boring as harmony be?

He shouldn't have underestimated his opponent.

King Sombra’s dark influence was obliterated by the Crystal Heart, and the villain is well and truly dead. But when he attempts to steal the afterlife of an innocent victim, a human spirit is left hurtling towards Equestria, where this unfortunate soul is revived into the only vessel available: the reconstituted body of King Sombra himself.

Thus, a cheerfully oblivious alien is crammed into the form of the most evil and malicious being Equestria has ever known. Not that Shining Armor and Cadence know this, of course. As far as they are concerned, the King is back and he’s lost his fricking mind.
