Billions of years ago, the Green Lantern Corps was formed to serve as an intergalactic police force. In order to be selected as an officer of the Green Lantern Corps, you must have the ability to conquer great fear. As a Green Lantern, your Willpower is the force with which you fight evil and defend the innocent. You represent the finest ideals of not just your planet, but your entire sector of the galaxy. The Oath of the Green Lantern Corps: In brightest day, in blackest night, No evil shall escape my sight. Let those who worship evil's might, Beware my power... Green Lantern's light!
