The Corps is the root of all order and knowledge. The Corps is the maintainer of life and guardian of truth. Without the Corps there would be only chaos and darkness. The Corps is without fear. Without anger or corruption. It is the creation of a highly-evolved mind and maintained by like beings whose destiny it is to maintain the order of things in the universe. The Corps has battled against the forces of chaos for a millennium. To serve is the ultimate honor. Knowledge is the sum of all reason and perception. Power is force prevailing over mass. Power without reason is chaos. Force without knowledge is destructive. The Corps is ultimate knowledge harnessed to ultimate power. The Lantern is the source.
