So in this world, everything is about the balance of forces. Many forces can take on physical manifestations and travel between planes of existence. At the dawn of the first people, Chaos was trapped between the physical and astral plane by Order* to aid the growth and development of Humankind, sacrificing itself in the process as to forever keep Chaos in place, acting as a layer between planes. Peace reigns for many ages and Humankind prospers, up until the point where Order, weakened by the growing unbalance between people and nature, is finally bested by Chaos, who falls from the sky down to earth and begins to wreak havoc. Life and Death, the forces that act as bridges between the planes, take it upon themselves to defeat Chaos and, in doing so, restore Order. However, they fail to work together efficiently as a team and lose. Weakened, they flee into suitable human hosts, take over and sleep for uncounted years to restore their strength. When their bodies awaken, their minds have forgotten what they once were and they find themselves in a world ruled by Chaos.
*referring to how chaos can literally mean the space between heaven and earth
