Twilight walked out of her library. Her studying session was a sucess. Within a month, she would have a prototype of Equestria's first nuclear reactor ready. Still, how on Equus did Pinkie Pie, the doctor, and Derpy get those schematics? There was something fishy...
Suddenly, a fish fell on her face. She looked up, to see Derpy crying.
Using her magic, she floated up to the grey mailmare soothed her and asked, "Hey Derpy, what's wrong?" She had helped her with the schematics, and it was Twilight's turn to help out a friend!
Derpy looked at her sadly, and said- "This weird alicorn who looked like he had lost a fight with a painter punched me in the face!" And continued to sob. Twilight stared at her then slowly asked- "An alicorn? Are you sure about that Derpy? The only alicorns are Celestia and Luna, and those two would never do someting like-"
She stopped as she heard an explosion. A pale white pegasus mare with a cutie mark of a pen and paper flew by, followed closely by princess Luna who looked intent to kill. As they watched, over nine thousand lazors flew out of her eyes and hit the mare in the tail. As the pegasus fell to the ground, stunned, a massive image formed of mist, took shape over her. It was a horribly disfigured face, made up of black and white lines appeared. It grinned, and said-
"Greetings. I am the god of the Trolls. I have come here after transforming murderers into 14 year old nazis, destroying the Twilight universe, cancelling Half Life 3, causing several game servers to crash, and creating multiple shitty customer service people to troll YOU, the lucky people of Equestria!
Let the trains, begin!"
At which point an army of I like trains guys fell into Equestria.
