Everypony knows the story of Nightmare Moon, the mare of darkness who threatened Equestria over a millennium ago, who returned and was defeated by the Elements of Harmony. Yet history is written by the victors, and the truth is often lost to the shadows. I am the last of the Sacred Scribes, an ancient guild of scholars entrusted with the task of safeguarding the secrets of the Equestrian Royal Family. On my deathbed, I put this account into writing, forever ensuring that the truth surrounding the imprisonment of the Exalted Lunar Princess and the Salvation of Our Celestial Mother shall be neither lost nor forgotten.
