Green Lantern Corps

The Green Lantern Corps is an inter-galactic police force dedicated to protecting sentient life in every form. Established thousands of years ago by immortal beings known as the "Guardians of the Universe" Green Lantern Officers are chosen for their ability to overcome great fear and are given a power ring fueled by the strength of their willpower.

Each member has a great deal of autonomy as to their methods in their jurisdiction, subject to review by the Guardians if they feel the Officer in question has abused his/her assigned authority. The individual Lanterns are responsible for arranging their replacements if they are near retirement or death. If the Lantern dies before that obligation is met, the ring will find and seek another to be trained on its own. In rare circumstances, Guardians will personally go out into the field to recruit a replacement.

"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!"
 * —Green Lantern Corps oath
