Once upon a time, in the magical land of Equestria, there were two regal sisters who ruled together, and created harmony for all the land.
To do this, the eldest used her unicorn powers to raise the sun at dawn; the younger brought out the moon to begin the night.
Thus, the two sisters maintained balance for their kingdom and their subjects, all the different types of ponies.
But as time went on, the younger sister became resentful.
The ponies relished and played in the day her elder sister brought forth, but shunned and slept through her beautiful night.
The Formation of Nightmare Moon(SCP-N1GH7M4R3 M00N).[]
One fateful day, the younger unicorn refused to lower the moon to make way for the dawn.
The elder sister tried to reason with her, but the bitterness in the young one's heart had transformed her into a wicked mare of darkness: Nightmare Moon.
She vowed that she would shroud the land in eternal night.
Reluctantly, the elder sister harnessed the most powerful magic known to ponydom: the [retracted].
Using the magic of the [retracted], she defeated her younger sister, and banished her permanently in the moon. The elder sister took on responsibility of the [RETRACTED] and [RETRACTED] and harmony has been maintained ever since.
