In a distant alien continent, the undead were once a race abandoned by the gods. Their souls were imprisoned in their decaying bodies, and they would linger on the edge of life and death forever. After being sealed for thousands of years, the young Aesel, the last descendant of the undead tribe, unexpectedly awakened his ancient bloodline and gained the mysterious power to control life and death. However, this power has also attracted the covetousness and pursuit of various forces. The human kingdom sees him as the source of disaster, while the elves see him as a threat to the balance. Only the mysterious prophet of the undead told him that he was the only "soul-drawer" in the prophecy who could undo the curse of the undead. In order to save his people, Esther embarked on a journey to find the "Key to Life and Death". In this continent full of magic and conspiracy, Esther must face obstacles from within humans, elves, orcs, and the undead. Every step he takes is accompanied by betrayal and sacrifice, but the truth is far crueler than imagined. When the seal on the door of life and death is lifted, how will Esther choose? Become a new god, or completely end the fate of the undead?
