The evil ones are the reasons that we sharpen all our blades.
We live within the shadows, and the evil ones we kill...
But we are all a family who only have a single will.
Death is our own appetizer, Survival is our meal.
Without it, we will suffer with a pain that none can heal.
Behold, dear mother, we have come to save you when you need.
When we hear your lullaby, we make the evil bleed.
You were the one who saved us from a life to live alone,
and now we live together, with a power long unknown.
You taught us all to be the ones who carry out the light,
and we'll always be your children... the Children of the Night.
-Gari, of the Children of the Night
Whenever the Elements of Harmony are defeated by Tirek, they all ended up captured by the hate-filled ruler, and have been given the death penalty, alongside their princesses; Cadence, Celestia, and Luna. They, along with many other ponies, (primarily the heroines' relatives) were also given the death penalty.
Amongst the rabble, while the "shadow knights" prepare the ropes over the necks of their first victims, the princesses, Celestia, Luna, and Twilight Sparkle, an elderly green mare silently places a dark blue music box, and winds it up. While the music begins to play from it, she silently says a prayer... while the changelings finish stringing the ropes over the princesses' necks.
