This is a translation of the mythological story told in this Fabula Nova Crystallis video shown at the January 18th 2011 Square-Enix Conference.
Once upon a time, a god ruled the world. He was called Buniberzei.
Buniberzei defeated his mother, the goddess Muin, and took control of the world for himself.
Muin disappeared into the unseen world--the invisible world.
Buniberzei was a god with many troubles.
The world, it was certain, was destined to die.
He believed this was a curse laid on the world by his mother Muin. Buniberzei knew he had to destroy her.
To do this, he must search for the door. The door to the invisible world where his mother waited.
Using his will alone, he created the first fal’Cie.
First, he created fal’Cie Pulse.
The duty he laid on him was to open the world, and search for the door to Muin.
Next, he created fal’Cie Etro.
But it was a mistake. Unknowingly, he created her exactly in the image of Muin.
Buniberzei feared her, and gave Etro no power of her own.
Instead, he created fal’Cie Lindzei.
The duty he laid on him was to protect Buniberzei from all who might seek to destroy him.
Buniberzei gave Lindzei one special duty. To wake him once the time came.
Then he turned to crystal, and fell into an endless sleep.
Pulse wished to expand the world, so he created many fal’Cie and l’Cie.
Lindzai wished to protect the world, so he created many fal’Cie and l’Cie.
But Etro was powerless, and could do nothing of her own.
Lonely, she thought of her mother, who she so resembled.
Etro tore at her body, letting her blood flow to the earth, and disappeared from the visible world.
From that blood, torn from her body, sprung humankind.
Creatures that were born, only to die.
The destruction of the visible world was no curse, only fate.
The world was divided into two halves, the visible and the invisible.
If the balance between these two were destroyed, the world itself would be destroyed.
The goddess Muin could do nothing to stop this fate.
She was being swallowed into the chaos of the invisible world.
Just before her last moment, Etro came to her side.
Muin told Etro that she must protect the balance of the world, before slipping into the chaos forever.
But Etro was foolish, and didn’t know the meaning behind Muin’s words.
Etro was lonely, but she felt affection for those humans who live only to die.
As they died, she smiled, and gave them chaos.
The chaos Etro gave them, the humans named “heart”.
Their hearts would become their power, but the humans did not yet know this.
Soon, they called Pulse the all powerful ruler. Lindzei they named their protector, and Etro... Etro the named ‘death’.
The humans lived on the world, hold chaos inside them.
Because they held chaos so close, the world once again was in balance.
And Buniberzei still sleeps. A crystal.
Until the end of forever...
