Banshees

Souls can meet their end through more than the blade or powerful magic. Some experience such grief that they lose the will to live, remaining but empty husks of their former selves until their untimely death. However, even after death, their souls keep mourning, returning from the beyond to spread terror among the living. They are cruel and cold, feeding off of the fear they cause others with little regard for their suffering. Perhaps their souls will one day find peace, but until then, they are destined to roam the plains of this world.
