After discovering that Cadence is not who she appears to be, Twilight is sent to another world entirely by the disguised Changeling Queen to avoid her plan being disrupted.

Tech Leader, a brilliant, but sadly racist Earth Pony, has made a mistake and managed to anger every single hero in Equestria. So she heads to her lab to escape into the future. One problem - several of the ponies who are angry with her are immortal. Which means they can wait...

Twilight Sparkle has been serving her country as the Princess of Friendship for over two years, and she thinks that it's finally time for her to take the next step in her royal career: she wants a fancy enchanted mane, just like Celestia and Luna. Luckily for her, the process behind it is pretty simple—all she has to do is go petition the legendary Author of All Beings. You know, the one that lives near the supermarket. Surely she'll be willing to grant Twilight her new magical princess mane!

Unfortunately for her, there's one catch: the Author of All Beings is a complete troll.
