An ancient prophecy tied to the emotional spectrum is fulfilled when the dead begin returning as Black Lanterns, beings animated by black rings capable of exploiting the emotions of those they face. Hal Jordan, the Green Lantern Corps, and several heroes of the DC Universe discover that this massive resurrection is connected to Nekron, the embodiment of death, who seeks to extend his power across all creation. Faced with this threat, the different Lantern Corps must overcome their rivalries and unite, while the living and the dead clash in a war that affects both the heroes’ personal bonds and the cosmic balance.
