Finding herself unable to sleep, Princess Celestia occupies her mind by penning a letter to Twilight Sparkle. But for a weary princess, the mind has a tendency to wander...
With her new apprenticeship under Nightmare Moon, Empress of Equestria and Queen of the Eternal Night, the orphan filly Twilight Sparkle plunges head-first into the conspiracies, secrets and intrigues of the Empire.
In the future, we'll colonize the solar system, cure cancer, clone the human genome, and build trans-dimensional hoodies that can summon tiny talking horses from an alternate universe. It's pretty snazzy.
