IN BRIGHTEST DAY, IN BLACK OF NIGHT,
NO EVIL SHALL ESCAPE MY SIGHT!
LET THOSE WHO WORSHIP EVIL'S MIGHT,
BEWARE MY POWER--GREEN LANTERN'S LIGHT!
oath of Hal Jordan, Green Lantern of Sector 2814
The Guardians of the Universe chose the most fearless of each space sector to battle evil and injustice throughout the galaxy. These elite--the Green Lantern Corps--comprise the largest lawkeeping force in the universe. For centuries, these Emerald Crusaders have fulfilled their duty to guard the inhabitrants of their sectors, and for centuries, their Power Rings have been passed on to worthy successors so that te tradition of the Green Lantern Corps may continue.
This sourcebook features the best known of these fearless members of the Green Lantern Corps (Hal Jordan, Guy Gardner, John Stewart, and Katma Tui among others), with statistics for their friends (such as Green Arrow, Black Canary and Omega Men) as well as their enemies (such as Sinestro, Star Sapphire and the Predator).
