Green Lantern (1990-) #145

It's the end of an era for Kyle Rayner, and the beginning of something far more dangerous than he's ever had to deal with. The Guardians of the Universe created the Green Lanterns to maintain order and peace, while their polar opposites, the Qwardians, believed only in bringing about disorder and chaos. Now their champions, Kyle and Nero, battle for control of the greatest source of power either of them has ever had access to. To the victor go the spoils, but the prize may prove too grand for either man to handle.
