Twilight Sparkle knows better than anypony that an exam is serious business, particularly when the exam in question a final exam. Particularly-er when that final exam determines whether she graduates from the Canterlot School For Gifted Unicorns. But exams aren't always fun. Or normal. Or non-homicidal.

Note: the AI character's voice is funniest when read in this voice from Portal 2:

[Part One of the Riflepony Series] When an unexpected heat wave scorches Appleloosa, Braeburn finds himself unable to save his family's apple orchard. That is, until he meets a certain pony whom he thought to be fictitious. The mare tells him of a treasure that is said to be buried in the town of Dodge Junction, and asks for his assistance in finding it. Will the tales of Cunning the Colt's treasure prove to be true, or were they simply folktale?

The royal court of Canterlot welcomes its newest member with open forelegs: the human philosopher Voltaire, from Earth.

On Earth, Voltaire is known as the greatest enemy of tyranny in the history of literature, and a legend in his own mind.

On Equestria, the court betting pool is giving him a week before the Princess banishes him to the Moon.

Note: This story doesn't have sequels per se, but there are a couple of short follow-ups set in the present day ("Parade Coverage" and "Secret Histories"), and a prequel of sorts in "At the Inn of the Prancing Pony".

This story is a sequel to Windfall

Sequel to Windfall, set three years after the events in that story.

The storm is breaking on the Horizon.

It's been two months since the battle against Nightmare Moon. Luna is recovering, Celestia is busy turning the government back into a diarchy, and the Mane Six have returned to their lives. All seems well, but when Celestia discovers that half of the power of the Elements of Harmony have been transferred to each of the Bearers, she decides to send thirteen mysterious members of the Royal Guard to monitor them as they manifest and develop their new abilities.

The sins of a forgotten war still linger, and an ancient evil lurks in the shadows, just waiting for the right time to strike. The Mane Six suddenly find themselves once again at the heart of a conspiracy to bring about Eternal Night, and only by awakening their powers and realizing their full potential can they do anything to stop it. Friends both old and new will help them along the way, and an unseen force will guide them as it seeks to right a wrong made thousands of years ago. The Bearer's journeys will take them outside the borders of Equestria and into the world beyond, and when they return, they'll have the power and experience necessary to save the world and bring about balance in all things.

Shawn Spencer, psychic detective, is a thick-tufted boy genius who ice skates through life on polished blades of snarky eloquence. He has tested himself against some of the greatest criminal minds of his time and emerged victorious... though often through unbelievable luck and not a small amount of bumbling.

Now, he faces a challenge unlike any before. One that will test his mind, his sanity, and his adaptability as he is thrust into the midst of an unfamiliar world and the ponies who populate it.

The Mane 6 face their own challenge, as an old enemy, tempered in the crimes of a much harsher world than theirs, returns to Equestria. It is a challenge they are ill-prepared for and one that only their strange, new, alien friend can help them overcome.
