Magic is an ancestral power that flows within the will of a living entity, and it is released through the amount of mana one possesses. Mana is like petrol; once a spark is introduced, it ignites a grand level of flames. That is how magic functions.
Mana serves as the fuel that brings magic into reality. The most well-known aspects of magic are the elements. The four elements are predominantly practiced in magic, but only a select few have been known to create their own magical arts.
Gravity magic is a fundamentally recognized form of magic, as is barrier magic, both of which, like elemental magics, fall under the category of fundamental magical arts. However, there exist magics outside these fundamentals.
