In ancient times, when the earth's civilization was still in its infancy, an unknown "rift" broke the unity of the world - the originally complete civilization territory was divided into countless parallel planes under the impact of the energy torrent.
One of these planes is the "real earth" that is known to future generations of humans: the laws of nature govern the operation of all things, and special energy has been buried by the years, leaving only sporadic traces in ancient rock paintings and myths and legends (for example, "The Suiren drilled wood to make fire" was interpreted as the original imagination of "fire energy", and the legend of "Thunder God and Lightning Mother" coincides with the characteristics of thunder abilities).
One of the planes became the carrier of the "Apocalypse World": the special energy retained by the "rift movement" settled here, gradually forming "elemental power" (thunder, fire, earth, water, metal, wood) that can be perceived and manipulated. Some humans awakened from the energy infiltration of the star ring, gained the ability to control elements, and became "Apocalypse" - their existence constitutes the secret guardian system of this world.
