(OLD) Progenitor of Mana (OLD)

Leo had always dreamed of the feats. he would be able to accomplish if he had access to something like magic. Creating technology that ran on mana, ruling kingdoms by an iron fist, exploring a vast world full of adventure. But alas his world never had any until one morning when everything changed because of a System?

This story is not for the light hearted, at least that is the direction I have it going.
