In 2177, the world changed forever. The first full-dive VRMMORPG, 'Eclipse Online', was released.With its breathtaking graphics and adventures, countless players and already established guilds flocked to the game, which stunned the entire world and forced the largest conglomerates to act immediately after gold could be bought with money.It was supposed to be the future of gaming.For Yone, it was the cause of his destruction.Starting over once more, he has entered this “living game” again to control his own fate.This time, he will not be controlled by others and will instead walk his own path.“Kill them till they are allies”This was Yone's infamous phrase as he will rise from just an assassin expert to an unprecedented peak in this life.

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!
