The Square Enix 1st Production Department Premiere had some interesting visuals and information other than the feasted trailers of VersusXIII and XIII Type-0. Square-Enix delighted the audience with a terse review of the Fabula Nova Crystallis mythology that I believe was introduced in text document on the Japanese FFXIII website.
For those of you who are interested in the mythology behind the Fabula Nova Crystallis: here's a quick translation of the curtail summary found off of the famitsu website. I think the summary sheds a lot of insight into the VersusXIII trailer and the character's interest with the painting of the goddess Muin and of course the subterranean intricacies of plot in Final Fantasy XIII. If you can't read Japanese, read the translation below. :)
-The world is governed by the god Buniberuze.
-He defeated the mother goddess, Muin, and therefore, the world fell into his hands.
-With Muin's defeat, she became unable to see the world and created the invisible world. Consequently, Buniberuze became anguished due to her actions.
-Because the world is finite, a horrible destiny exists. Buniberuze believed this curse was caused by Muin and therefore, thought it fit to defeat Muin to lift the curse.
-In order to reach Muin in the invisible world, Buniberuze created Fal'cie, the first being Pulse to search for the entrance into the invisible world.
Pulse's mission was to cut the earth and find the door.
Buniberuze then created the Fal'cie Etro. Buniberuze made the mistake by making Etro look familiar to Muin. Fearing its form, Buniberuze did not grant Etro any powers.
-Instead, it created the Fal'cie, Linse. Linse's mission was to solely protect Buniberuze and to enter crystal stasis when the right time presented itself [but this is not explained fully].
-Pulse decided to create its own Fal'cie and L'cie in order to conquer the world.
-Linse on the other hand, decided to create its own share of Fal'cie and L'cie in order to protect the land.
Etro however, was unable to do anything. Lonely, Etro wounded himself and sank into his own blood and then soon disappeared.
From the flowing blood of Etro, man was born. Man's destiny was to be born then eventually die.
-The world was based on the balance of the world of visibility and invisibility. If that balance was broken, the world would collapse.
-Buniberuze did not stop the fate of Muin, thus, she was engulfed into the chaos of the invisible world. When Etro came to rescue Muin, she simple told Etro to keep the balance of the world before falling into the invisible world.
-Etro was foolish and did not comprehend the words of Muin.
-The lonely Etro became intimate with the specimen known as man, and gifted man with a smile and chaos.
Man named the gift granted to them by Etro as "Heart/Emotion." The Heart or Emotion was to become a power, but the humans did not know of this yet.
-Eventually, Pulse became the omnipotent ruler, Linse the guardian, and Etro the God of Death.
Thus, people began to live in the invisible world of the heart and the people who face the chaos can barely maintain the balance of the world.
As a conclusion, Buniberuze will remain in a crystallized sleep until the end of eternity.
