green lantern: full spectrum

At the beginning of the Universe, the guardians developed the green lantern corps to keep peace and fight evil throughout the universe, which they divided into 3600 sectors each patrolled by a lantern, and eventually by two. They used the light of will, but over time, other portions of the emotional spectrum were harnessed and several corps now enact their vision of justice around the Universe from the Green and Blue lanterns to the Sinestro Corps and Red lanterns, and the threat of a return of the blackest night. These heroes and villains wield powerful rings in pursuit of their corps goals.
