The assassination of Heaven

Glen, also known as "Dusk", was a former black-ops agent turned world-class assassin for hire. The targets he got assigned ranged from stealing priceless jewels from private collectors to extracting information from leaders of world renown terrorist organisations. His life-long dream was to buy a deserted island far away from civilisation and live there in piece. Soon the opportunity presented itself as he only needs to complete one more mission to get enough money to disappear.
Unfortunately, Glen got set up on his finale assignment and was left for dead. On the brink of death his soul travelled into another universe into a body of a child.
This is a story about a mortal that was able to suppress the Gods, subdue continents and leave behind him an ultimate legacy that will be recited to every generation to come.
