The events of “War of the Green Lanterns” has had more consequences than the Green Lantern Corps ever fathomed. As a result of the conflict, an ancient evil in the farthest reaches of the universe has broken free, consuming countless Green Lanterns in its wake, feeding on the vast energy of their power rings. To halt its path of raw destruction, the Guardians send an elite crew led by Guy Gardner to find it and halt it — permanently. Can Guy and his team stop this beast before it reaches Oa? GREEN LANTERN: EMERALD WARRIORS #12 comes from the creative team of Peter J. Tomasi, Chris Batista, and John Dell, and is available in stores today.
