The Elemental World was a world where all living beings possessed a special feature within their bodies known as a "core," located near their hearts.
This core enabled them to harness a power known as "Elemental Arts," which was a form of magic unique to the Elemental World.
Each core belongs to one of four elemental types: fire, water, wind, and earth. Cores would awaken when a living being reached the age of five after birth.
Awakened cores also possess different levels of proficiency, referred to as talents.
These talents indicated the individual's mastery over their elemental abilities.
However, there were also sentient beings who awakened an essence outside of the four elements, known as "Specials."
These individuals were incredibly rare, with a ratio of 1:10,000,000 compared to core-awakened beings.
The Elemental World was further divided into four major continents: the human continent, the demon continent, the elven continent, and the monster continent.
The power system in this world was categorized into four major levels, each requiring extensive time and effort to accumulate, as it depended on an individual's talent to progress through each level.
