This story is a sequel to Of Solicitude

Ten years after a massive war, Equestria has changed. The Empire now rules over all, giving peace and prosperity to those that deserve it, but some are against this new rulership.
The CMC, a small, raggedy group of smugglers working for the Apple family, are caught red-hoofed by an Imperial patrol. As the friends fight for their lives, they learn about themselves, each other, and the world they now reside in.
Meanwhile, in Canterlot, Emperor Blueblood has amassed a massive fleet and is preparing to smash what is left of the rebellion under the oppressive hoof of his Empire.

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...

When one of Fluttershy's dear animal companions wanders into the Everfree, she sets out to bring him home safely - but what she finds at the center of the forest is something she didn't expect, and something that ushers in a change to her world that makes each day darker than the last.
