A long time ago, there was no mortal life form in the universe, only a very powerful spirit entity. But on a certain day, various dimensions began to emerge through this spiritual entity, and it was at that moment that the first intelligent life form was born in the first dimension that was created. This life form possessed a power that in theory no mortal should possess, the so-called "Elemental Manipulation". This is a power that allows the individual to have the strength needed to manipulate the elements, a power that only a "God of Creation" would have in their possession.
The first intelligent life form that was created in the first dimension was given a special name, he was called "Mystic", and that name was given to him by the spiritual entity that created all dimensions as well as the life forms that inhabit them. . This entity is called the "Mystic Aura". All the dimensions that existed were separated by several barriers, preventing contact between the living beings of these same dimensions, but the first dimension was the most special, because in it there was a barrier that sustained the energy of the others, the Kagatari barrier, a barrier made with an energy created from the junction of all elements and the true essence of the Mystic Aura. The Mystic Aura called this energy "Adawa", and the being that is in charge of protecting the barrier and maintaining balance between dimensions is the Mystic.
Several living beings awakened the same talent, which is Elemental Manipulation, some could manipulate only one element, others could manipulate two, three, and even four elements, but only the Mystic had something special in his body, which is the presence of the "Fifth Element", a force of nature created by accident from the moment the Mystic Aura created the Adawa energy. This Fifth Element has 3 variations, in some cases it can be Lightning, in others Ice, and even Steel.
The first Mystic that ever existed awakened the Fifth Element of Lightning, the second awakened Steel and the third awakened Ice, there is no standard sequence to know which variation of the Fifth Element the Mystic will awaken, but what made the Mystic Aura choose as their guardian the lifeforms that possessed the Fifth Element, was because of the unique ability they possess, the ability to store the elements in their body and transform into "Mystic Energy". Thanks to the Fifth Element, the Mystic is able to absorb the energy of the elements and transform it into a unique and refined energy, similar to the true essence of the Mystic Aura, and that was the reason why the Mystic Aura chose that life form to be the guardian of all your knowledge. In all dimensions, only the first one that was created has the true essence of the Mystic Aura, which is why there is only one Mystic in the universe, well... at least that's what everyone thought...
