During a different time tens of thousand years ago, humans advanced to the magus realm in various different ways.
Be it through divine artifacts, divine beings or surviving the tribulations, humans had to receive extreme fortune or go through extreme difficulty in order to become a magus.
Until one day, a group of ancient magus invented the key to the path of immortality: a solution for humans to cultivate and reach the magus level without having to go through such dangers.
This key was the Awakening Scroll.
It was the greatest invention of the human universe and for the human race, the beginning of their rise to becoming one of the major powers of the universe comparable to the elven race.
