Prior to the Blackest Night event, Black Hand ("leader" and first member of the Black Lantern Corps) had already been established as a villain within the pages of Green Lantern. Writer Geoff Johns revisited his origin and expanded upon certain aspects of it during the Green Lantern: Secret Origin story arc (2008). During the arc, Hand's energy-absorbing weapon (previously thought to be an original invention) is revealed to have been constructed by Atrocitus, enemy of the Guardians of the Universe and future founder of the Red Lantern Corps. Atrocitus comes to Earth and approaches Hand, recognizing him as a "doorway to the black" that possesses the power to bring about the Blackest Night. Hand manages to escape and pockets the weapon as he flees. The possession of this weapon soon leads him to become an enemy of the Green Lantern Corps, as he now feels a need to extinguish the light of the emotional spectrum.
