The White Lantern Corps Power Ring channels the power of the White Light, the combined power of the seven Light Based Corps. The White Lantern Power Ring was first seen during the zenith of the Blackest Night: Nekron, Lord of the Unliving and mastermind of the Blackest Night, murdered one of the Guardians of the Universe and used his energy-ridden organs to summon the Entity. Nekron used his scythe to try and kill the Life Entity while Hal Jordan attempted to join with it to give it a chance to fight back. Sinestro, claiming his right to the being and stating that Jordan had "had his chance" with Parallax, absorbed the Life Entity into himself. Emerging as the first White Lantern, Sinestro bore the first White Lantern Ring.
