After thinking of all these, Jeremiah immediately gathered his compatible energy, which was mana, from his body to enhance his flame ability that gathered around his hand hands.
The reason why he was his energy was mana and not magical energy was because he was an evolved human that awakened an innate fire ability and not a magician that uses the mana as magical energy when they use their spells.
Although the names could be interchangeable depending on the group of people or type of world one visited in the future.
That was because, in some worlds, the concept of mana itself was defined as the energy of their planet and when humans or other creatures absorbed that energy into their bodies, it becomes a conduit to conduct magical spells or supernal phenomena.
And thus, it was called magical energy instead of mana since mana was the raw energy without being cultivated and magical energy was the cultivated mana.
