Netheles are physical-realm ghosts that are cursed to haunt cities and forests. They are not necessarily evil but are tricksy, always trying to trick the people they encounter into doing something foolish. Netheles don't have mouths, but can speak to people telepathically in a way that emulates the sound of the listener's own voice. They often play pranks on people by taking their stuff and moving it around until they get very confused, but older or more aggressive netheles occasionally resort to more harmful and ill-willed pranks and trickery.
