The group was founded by Vandal Savage to counteract the Justice League's role in preserving society's "calcified status quo". In his view, the League inhibited mankind by protecting it from disaster, crime, and tragedy—factors needed for humanity to evolve.
To counteract this, the Light created or co-opted networks of operatives, placed key individuals in key positions, and explored the boundaries of all new technology. Genetic engineering, biochemical engineering, robotics, nano-robotics, techno-sorcery, and all conceivable methods of mind control were all explored by the Light in its quest to accelerate human evolution. A resurgent Earth "taking its rightful place at the center of the cosmos" appears to be the Light's ultimate goal.
