Journey: The Destructive Incarnate

In the Stellar sea of stars, a giant tree stood, rivers made of countless white streaks flowed throughout its giant body travelling toward its root.
Those rivers were made of souls going through the process of rebirth, but among those countless rivers, a certain stream travelled directly toward the stem of the tree.
In that specific river, a soul flowed like every other; nothing special about it would have remained as such.
Suddenly the space it inhabited collapsed as a brilliant golden glow travelled out of that distorted space.
The soul unable to escape got showered by that golden glow, its spiritual body absorbing it. Unable to handle the magnitude of the power contained in the golden light, the soul started to tear up.
But somehow it managed to absorb it all, but it came at a cost, as the single soul split into two, one being thrown out of that river.
Passing through another river, it made its way toward the root, whereas the other part continued on its way.
A soul who got the body to handle the power of the golden glow after rebirth but didn't have it, and a body that had the power but couldn't handle it was created.
But fate works in mysterious ways as after the death of one body, the soul finally reunited making someone whole.
Neo was the part that got the power but couldn't handle it, this gave him a fate worse than death. He couldn't use mana, in a world filled with mana and where the strong ruled.
But his family didn't give up on him or shun him, so to help them even if a little he chose the path of a scholar.
Knowing that he had the talent to be a mage but couldn't use mana always ate away his heart. Then on the fateful day when he was four, the soul finally reunited, becoming one.
All the talent he had finally burst forth, as Neo was born anew, now with memories of 30 years worth of life and the vast amount of knowledge he had collected in this life.
So with that, how will he change this world, how will his existence affect the world, and will he be swept away by this world? It is for you to find out as you follow his journey.
