Diablo Volfir, a mighty magician, was sealed for aeons due to the schemes of the 12 Gods, but 66666 years have passed since then, and he descends to earth once again!

“I wished them immortality but my thirst for redemption caused them suffering, I gave them eternity yet brought the end of the world” Ethan mumbled as he dragged himself from the ruins of the Golden throne. “You should understand me, human, what I wanted, was eternal happiness...yet I received torments from my own wish” “You call me a human, aren’t you the same?” Replied a faint voice. Ethan laughed in response before saying “ Human? I am beyond humanity, I am...a God!” _____ The world was no longer what it once used to be. A thousand years after the birth of Nexulytes, people who were able to wield Nexus energy and awakened miraculous talents with unimaginable abilities, the earth had fallen to the brink of near extinction with just less than twenty percent of its population left. The Dreamscape, also known as the reflection of the real world, was a space that was shockingly similar to the real world and copied every small detail of the real world. Their only difference was that the Dreamscape was not a place where humans could move about easily as even the strongest Nexulyte could die without knowing how. Years after the appearance of the dreamscape and multiple gateways spammed all across earth, giving the horrors of the dreamscape access to the real world; they unleashed chaos and a hundred years of bloody battle were the consequences of humanity’s late response. In a world where those with talents were worshiped and respected, a boy who hated Nexulytes and wished all of them could die ended up becoming one himself. Not only did he become what he hated, but he awakened a talent that he had never heard of or known about. How was he supposed to survive the fusion with a seemingly useless talent or was he ever going to find out the secret of his talent and the birth of the dreamscape?
