The Genesis Game: Volume I

The end of the era of humanity was marked by the appearance of the World Dungeon and the system of power it provided. No one gained more power than the tyrant known as the Black Seraph, the Angel of Genocide. Surviving at the expense of the rest of humanity, Seraph was able to complete the World Dungeon upon reaching the Altar of the End. A hollow victory, as he was cursed by the spirit of the dungeon for ruthlessly focusing on his empowerment. His power was sealed away, deep within the dungeon; Seraph was cast into the past, reincarnated into the body of his child-like self. Forbidden from hoarding power for himself and charged with the mission of ensuring the survival of humanity. But people do not change overnight, and Seraph must find a new path forward and learn there's more to power than being a tyrant if humanity is to survive the Genesis Game.
