This story is a sequel to Sunset Impossible
On the longest day of the thousandth year the Lost Princess shall return. And the Sun shall never set on her reign.
A thousand years has passed since the battle for the day that was later dubbed Nightmare Night.
Most of what took place that night has long since passed into legend; something Equestria's reclusive princess has done little to prevent.
Some say she wishes nothing more than to forget.
Others claim she is waiting.
Only whispers and stories remain. Stories of a lost princess, and the Nightmare she fell fighting.
The truth is far more terrible.
Twilight Sparkle, sole student, and confidante, of Princess Luna, knows nothing of the tragedy that has haunted her mentor for a thousand years. She also knows next to nothing of friendship.
That will soon change.
