Since the dawn of eternity, four lights of hope have shone upon the world.
Ponies flock to these lights, around which they build four peristylia.
Each peristylium becomes their faith and society, the path upon which they are set.

The Vermilion Bird—wings of fire to lift the heart.
The White Tiger—steely arms by which to seize knowledge.
The Azure Dragon—unclouded eyes that see all beneath the sky.
The Black Tortoise—a rigid shield and a well-guarded blade.

But when nine and nine meets nine,
Tempus Finis shall be willed upon them.
For without the Agito, their world—called Equestria–
must persist in its spiral.

War grips the land of Equestria, as the Lunarian Empire besieges the neighboring Dominion of Solaris, Kingdom of Concordia and Lorican Alliance, in its attempts to subjugate the Four Crystals of the land.

The only hope for the world are the Agito cadets of Class Zero

"When nine and nine meet nine, the depths of reason shall stir. When the seal of creation is broken, a voice like thunder shall sound, and thou shalt know - We have arrived!"
