Part 1: Lyra's Pyro Predicament
Part 2: Twilight's Demoman Devastation
Part 3: King Sombra's Robotic Retaliation

When a mishap causes two para-dimensional weapons to colide with one another, RED Team's Pyro is sent flying from the Team Fortress 2 universe into the alternate universe of My Little Pony, where he is almost instantly discovered by Lyra, who shelters him in her home.

Having him hidden in her small townhouse isn't easy; keeping him from setting things on fire, teaching him that not every cart that passes by is cause for alarm, and that blue ponies are not something to be suspicious of.

However, with Nightmare Night soon approaching, Princess Luna feels that there may be something more sinister riding on the coat tails of Pyro's grand entrance; the first human to ever set foot in Equestria some thousand years ago...

In the last five years humanity has been brought to its knees by the conversion movement and the purification that has followed. Now in its final hour the last survivors of this once great race will make their last stand. Set in the Conversion bureau: Ten Rounds universe.

Some secrets need to be kept, and others need to be set free; but sometimes, not even the Element of Honesty can tell the difference. How do you tell your family the truth about something that you can't even admit to yourself? When Applejack begins to realize that she may have feelings for a friend, she needs to find the courage to accept who she really is before she can truly be happy.

Princess Celestia is due for an informal visit with Twilight and her friends, but Pinkie Pie seems to be acting even more strange than usual. What is she up to, and will Twilight find out before it's too late?

I was really striving for an "almost like watching a new episode!" feel with this fic, and I hope it shows.

A minor accident at Sweet Apple Acres sends Big Macintosh to Ponyville in the middle of applebuck season. At first, things seem fine. But then some of the mares begin acting a little...oddly.

Then very oddly. Turns out every other stallion skipped town for a very good reason.

Robert Parker is a 24 year old ex-web developer living in New York city. In the wake of the conversion movement, he has seemingly lost everything. Haunted by the same nightmare every night, he soon realizes that he must make a choice.

To those unfamiliar with the Conversion Bureau: it is a scenario created by an author named blaze in which Ponies either appear in the human world or have lived beside humans without incident for millennia. One day, in the face of all the damage humanity has done to its world, the ponies offer a solution: undergo conversion to become a pony and allow the world to be inundated with Equestria's influence: thus healing it and bring forth a golden age.

Many different authors have taken many different approaches to this idea, all of them are worth checking out.

Twilight Sparkle is accepted into Princess Celestia's School for Gifted Unicorns and gets a little more than what she bargained for.

Illustrated by me.

(If you object to swearing, please skip chapter 6. That's the one chapter that bumps this story straight up to a Teen rating.)

When Rarity is given an order for a dress, a series of unfortunate circumstances lead her to request the aid of Twilight Sparkle. When she discovers that Twilight has been studying time spells, she asks if she can help her recover some of her time. Reluctantly, Twilight agrees, but when she is performing her spell, something breaks her concentration causing the spell to become unstable, sending them 15 years into the future. What awaits them in a world where they have been missing for so long? Will they ever get back to their own time? Only time will tell.
