"The Templar Guardians have been locked away for millennia, but they have a VERY clear idea of what they need to do next--and of all the Lanterns in the universe, they need a reluctant Kyle Rayner's help. But once he sees the strange anomaly lurking at the edge of the universe, he may have no choice but to get on board with their mission. Witness the beginnings of the next major Green Lantern villain in this landmark volume in GL lore with GREEN LANTERN: NEW GUARDIANS VOL. 4. Collects in hardcover GREEN LANTERN: NEW GUARDIANS #21-24, GREEN LANTERN #23, GREEN LANTERN ANNUAL #2, GREEN LANTERN CORPS #24 and RED LANTERNS #24, which includes the entire "Lights Out" crossover event"--
