Gamma World: The Infinity Arc
This is a quasi-monastic order, founded by a medical technician during the Shadow Years (the time leading up to the apocalypse). They wander continually, caring for the sick and wounded without regard for race, creed, or biological origins. The membership is both human and mutated and all have a mysterious ability to approach and befriend non-intelligent creatures. They use many medical devices of the Ancients, as well as any number of natural herbs and medicines. Healers are so respected by all (except the “Red Death”), that they are rarely attacked, even by the most bloodthirsty creatures.
Their symbol is a white coat, the caduceus (☤), with outstretched hands. Traditionalists are pacifists, who go out of their way to render medical treatment, while Reformist Healers demand payment for their services – only doing occasional charity work.
