More than 1000 years ago, something catastrophic happened that would change the course of Equestrian history forever. A young Princess, angered by injustices committed against her, will give in to her jealousy and rage and be transformed into a Nightmare.

This is a tale you will not find in any history books. This is a tale of betrayal, sorrow, and so much bloodshed. The unsetting moon was not a singular event. It was a war. An ashamed Princess Celestia had censored and altered the tale so that, whenever her sister did return, she would not immediately be hated.

This, however, is the true story of Nightmare Moon.

Princess Luna has been through a tough life. A thousand years ago she could not control her jealousy, envy and rage and became the infamous Nightmare Moon. Then, she spent a thousand years on the moon, only to return, still as Nightmare Moon.

However, despite everything she has been through, her return to Equestria was warmly celebrated. Princess Luna is a pony that everypony loves, and she is completely forgiven for everything that's happened.

So, when Princess Luna is suddenly and unexpectedly killed, the entire nation of Equestria is thrown into grief and despair. Ponies everywhere find themselves unable to deal with the tragedy.

But the worst hit is Princess Celestia herself...

This story is a look into the events that unfolded 1000 years ago that turned the the Crystal Empire from a harmonious paradise into a cursed dystopia.
