Mana was first undiscovered and laid dormant around the world, it was near in existent as for some reason it had reduced to an almost insignificant amount,at least that is what the scientist that discovered it had thought.
It happened sometime about over 10,500 years ago(that many years before the start of the novel)
Scientists were attempting to find an actual trace of dark matter but instead they had found...
Mana.
As if the recognition was it's source of energy,this mana instantly began to increase in magnitude and as if a chain reaction,all the mana of the world began to swell.
From then on scientists...no,humanity has been attempting to find out it's potential and applications.
And the age of mana recollection began.
