After finding the core region of the barren lands, the two wardens and two systems immediately run for it. The secret hidden within the center of the barren lands is simply beyond their control. Moreover, they truly didn't want to be affected by chaos energy. Even though this power is willing to make them stronger, as a consequence of accepting it, one can either turn into a crazy one who seeks endless battle. An urge that is extremely hard to control and it's worse than gluttony. If one is lucky and possess compatibility with this power they are able to transform into Chaos Creatures.
Chaos Creatures are protectors of Chaos flowers. They exist to prevent the flower of chaos from falling into someone else's hand. They exist only to protect chaos from spreading to something else. Its existence only had something to do with chaos itself and only those who can control chaos can see them.
