The collapse of civilization has reduced their people back to iron and horsepower. The Hyllises tend to inherit “tele-talents” such as telekinesis and teleportation. Tarc Hyllis’ mother (and his grandfather before her) could “feel” things with their talent. They became healers because they could feel inside their patients, which frequently let them diagnose the underlying causes of an illness. Having made a diagnosis, unfortunately, there was often little they could do to treat a problem.
