The Green Lantern Corps is an inter-galactic police force dedicated to protecting sentient life in every form, established thousands of years ago by the Guardians. Officers are chosen for their ability to overcome great fear and given a power ring fueled by the strength of their willpower, the mightiest weapon in the universe. They have two representatives for each of the 3600 sectors in the known universe, their headquarters located centrally on the planet Oa.
