The concept was created and developed by DC writer Geoff Johns from 2007-2009 as a reinterpretation of part of the Green Lantern mythos and has grown in prominence in the DC Universe with Johns' own ascension to his current position as DC's Chief Creative Officer in 2010. The concept's influence has culminated in the various Green Lantern series and in the company-wide "Blackest Night" and "Brightest Day" crossovers. The concept was also partially referred to in 2011's Green Lantern film, on which Johns served as a creative consultant and co-producer.
