Soon after Nightmare Night, a reporter comes to Canterlot Palace at night to interview the elusive Princess Luna. He's armed with the questions everypony wants answered about the mysterious princess.

Celestia and Luna have many duties as the leaders of their realm, such as raising the sun and the moon; but there are other duties, while less pressing, that must also be fulfilled. When those duties require an unwilling betrothal, Luna flees the palace, afraid of summoning Nightmare Moon with the force of her rage. With the help of the commoner Donut Joe, she treks across the unforgiving landscape of Equestria, facing monsters and risking her life while forging a new friendship - but will her escape have been for nothing?

The past can be filled with regret, but for Princess Luna it will come back to haunt her. When she releases her personal guards from 1000 years ago, she quickly finds the world flipped on its head. The changelings invade again and a greater darkness soon follows. Can these three ponies change fate or will Equestria be lost forever to darkness.

Nightmare Moon was but an old mare's tale, simple childhood hogwash, and with it the fact that Equestria had once had two princesses. Celestia thinks back on Luna and her eventual descent into madness, descent into a Nightmare.
