After Hal Jordan succumbs to the influence of Parallax and the Green Lantern Corps crumbles, the Guardian Ganthet travels to Earth and bestows the final Green Lantern power ring to artist Kyle Rayner. Rather than protecting just Earth and Space Sector 2814, it's now Kyle’s responsibility to guard the entire universe as the sole Green Lantern until the Guardians and the Corps return. During the Blackest Night, an army of Black Lanterns attack the Guardians’ homeworld of Oa where many of the Green Lanterns also reside, including Kyle Rayner. Looking to defend the planet, Kyle flies into action with the other Lanterns by his side!
