They didn't come from this world, but it's now their new home. The classes try their best to fit in in the new place, but it's not as easy as it seems. From learning new things to falling on old habits, everypony's got work to do...

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...

Discord is once again loose, but after using his randomness to find some interesting information on some strange phenomenon in another world that has to do with an island and a bunch of humiliating events, the crazy spirit of disharmony and chaos comes up with a new, sick, twisted, disturbing plan that involves capturing 20 of the most popular ponies (and three non-ponies) and forcing them to play a new game while the rest of Equestria watches in horror (or most likely secret amusement and possibly envy of not being picked themselves).

What does the rotten host Discord have in mind for our 20 unfortunate selections? Well, looks like you'll have to wait and find out! Maybe, just maybe, if Discord is feeling generous, the winner of his new "game" will get a grand prize. Everyone pick a character to root for and let's get it on!
