This event will span the pages of Green Lantern #24, Green Lantern Corps #24, Green Lantern: New Guardians #24, Red Lanterns #24, and conclude in Green Lantern Annual #2. Larfleeze will not be part of the crossover. I highly recommend that you pick up this week's Green Lantern #23.1: Relic because, not only is it a great read, it's also the unofficial prelude to the event.
“There are seven different colors of the emotional spectrum, each of them represented by their own corps. Green Lanterns wear rings powered by will, Red Lanterns rage, Yellow Lanterns fear, and so on,” GREEN LANTERN writer Robert Venditti told COMIC VINE. “For reasons none of the Lanterns are sure of, the rings have been malfunctioning lately. Enter Relic, a remnant of the universe before ours, who thinks he knows what's wrong with the rings and has a solution. Unfortunately, ridding the universe of every last Lantern is part of that solution.”
