- Description from Novelupdates

Lucien was chosen by the God of Gamblers to participate in the Heaven’s Gate Project. Their goal was to help save a dying world from destruction, and ensure that it wouldn’t be destroyed a second time.

Unfortunately, things didn’t go according to the God's plan. Lucien’s soul was heavily injured during the soul transfer and on the verge of collapse. Having no other alternative, the God of Gamblers was forced to take yet another gamble to preserve his chosen candidate’s soul and help him find a new vessel.

As if arranged by Fate itself, Lucien’s soul wandered into the world of Solais until it merged with the dead body of a newborn baby that was left to float down a river. With his new identity as Lux, the boy realized that even with the blessings given to him by the Gods, saving a world was not an easy matter.

In a world of Swords and Magic, where adventures run wild and free… the Legendary Saga of an abandoned Prince is about to begin!
