'A wise man once told me that 'Proper story's supposed to start at the beginning'.

We all know how this story starts. We all know how a thousand years ago, the Princess of the Moon betrayed her sister, the Princess of the Sun, and how a thousand years ago, Equestria lost one of its leaders.

What we never knew was that, a thousand years ago, two follies were created: a truce... and a promise.

And now, both of those have been violated.

We are about to pay the price.'
