After the changelings' failed invasion of Canterlot, Twilight tries to soothe some of Ponyville's rampant paranoia by casting a spell to prove there are no imposters hiding in the town.

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

After receiving a strange book from Pinkie known as "The Bombinomicon", Twilight wakes up one morning to find that the mystical tome has been stolen, by...Twilight?

Things quickly unravel as RED Team's Tavish DeGroot (Demoman) and Spy find themselves not only trying to get back home, but also fighting for their lives as villains from the Team Fortress 2 universe combine forces with some of the most dangerous foes Equestria's ever seen!

When Twilight was young, she used to sit on the balcony and look down at the statues in the royal garden. At the strange creatures of fur and armour and feathers and horns, and just...wonder on them.
And out of all of them, out of the unique draconequus and the rare Cyclops and the terrifying Invention Monkey, one particular statue always caught her eye.
Four...blocky, for lack of a better word, knights. Frozen in perfect formation, their heads hidden deep within the confines of their helmets. Each one stuck in the same pose, for as long as she'd known them.
And beneath them, engraved into the stone they were a part of, was a simple message.
"Wake us when something fun happens or Celestia stops being a bitch, whichever comes first."

Now with tropes page, all thanks to Eyeshield. Good work, buddy.

For almost a thousand years, the immortal Nightmare Moon has reigned over Equestria as Empress. To the average pony, Nightmare Moon is an overarching enigma whose rule is absolute and whose wrath is terrible. But to Twilight Sparkle, who as an orphan has never known her parents, the Empress is something else entirely. When the young unicorn is brought under the royal wing as an apprentice, she learns a great deal more about the supposed tyrant than she ever knew. But as Twilight is introduced to life with her new mentor, she is thrust into a world of political intrigue, conspiracies and secrets. Secrets that were never meant to be revealed. As allies and enemies plot against the very peace of the nation, will Twilight fall prey to the perils of her new position? Or will she prosper and find in Nightmare Moon the mother she never had?

Now with added TVtropes!

How could one love another if they could only live by evil? It has been over five-hundred years since the first, and much to her surprise, Chrysalis, queen of the changelings, has given birth to another changeling; the first changeling to have ever been born straight from the queen in such a long time span. Yet this one is not like the others. No, this one is much more different. How can a queen who feasts off love care for such a delicate creature?
