* The power of chaos
In 'FFXIII-2', the power of chaos performs an important function in many scenes. The characteristics of the power of chaos are as follows.
= the power filling the Unseen World
Chaos fills the Unseen World such as Valhalla. This is the power to engulf everything and return it to nothingness, and chaos filling the Seen World means the destruction of the world.
= the true nature of the hearts of man
Etro gave to humans the power of chaos that fills Valhalla. This is the true nature of people's hearts, and it can also be said that humans all carry within them a tiny Valhalla.
= the source of paranormal abilities
Those who harbour a high level of chaos are able to exhibit special powers, such as travelling to different points in time and space through the gates, and retaining their memories of the past history even after it has been altered. Additionally, in the time of 'FFXIII' only l'Cie were able to perform magic, but after the Castastrophy as a result of chaos flowing out of distortions in time-space and cracks forming in the borderline between the physical and the spiritual, many people gained the ability to use magic.
- [Lightning falling into chaos during FFXIII's ending]
Chaos, living up to its other name of 'unseen/invisible chaos', fundamentally is not visible, but at times it may appear as a black haze.
- [Serah holding her face in Sunleth]
The power of chaos is more easily found in those who have received Etro's intervention. Serah is a typical example.
- [Serah talking to Hope and Alyssa]
There is a limit to the total amount of chaos the goddess gave to people, so history will inevitably reach a singular conclusion (> P.48).
* Valhalla, a world filled with chaos
The story takes place in the Seen World where humans live, the Unseen World that is brimming with chaos, and the world that stands between these two. All that exists in the Seen World is destined to one day perish and be swallowed by chaos, and if the Seen World itself is engulfed by chaos it will be transformed into a world of death, without a past, present, or future. In other words, the destruction of the world means its assimilation with Valhalla.
= The bond between the worlds
[note: this is a little chart that looks like this:
]
{pink} Unseen World: There is no concept of time, space, or form. Perfect chaos.
{orange} Valhalla: There is no concept of time, and the concept of space is also vague, but there is form.
{arch} Gate - Gate
{midpoint of arch} Time-Space Threshold: The concept of time is rather vague, but space and form are identical to the Seen World.
{grey} Seen World: Has the concept of time, space, and form.
- Within the Unseen World, the existence of form in Valhalla makes it closer in nature to the Seen World. The cylindrical space connecting the gates is the Time-Space Threshold, and in parts where the cylinder is twisted into a dead-end one finds places such as the time labyrinths and the coliseum.
* Yeul, the first human
Yeul is the oldest human in the world. Unlike other humans, she cannot be reborn as another individual, so her rebirth with the exact same appearance and soul has repeated since the beginning.
Every Yeul has the power to see time, and for generations they have been compelled to live as the maidens of the Farseer tribe. In accordance with their laws, the maiden is not permitted to interfere in history despite their knowledge of it, but most of the Yuels wish for a history where even more people are able to live.
- Out of all the Yeuls through history, only the Yeul from AF700 was able to live freely, due to being the world's final maiden.
