In the Lanterns book it is written that, this evening, the seven Troops that represent the emotional spectrum (the colors green, red, orange, yellow, blue, indigo and violet) will swallow until death, resulting in the appearance of an octave, the Black Troop. It is a war between all types of Lanterns in the galaxy where several of the dead superheroes (and villains) (including from the multiverse and parallel lands) have come back to life to fight alongside the Black Lanterns. Basically in the plot we have the villain Blackhand using the Black Lantern of Death to raise all the dead, for example, Aquaman, Batman, etc., with the main intention that would be to raise Nekron, the bearer of the Black Lantern. From then on, during the saga, we accompanied Hal Jordan on a huge journey together with all the troops of the Emotional Electromagnetic Spectrum and the great heroes of Earth, having to face a threat on a cosmic level. The interesting thing is that during the saga there are 3 different lines of events: the main one taking place on Earth, another one taking place in Oa and then in Mogo.
