Blade Stalker

From publisher blurb: Blade stalkers are a menace to the lands of Khrota, they stalk the night with relative impunity. These terrible creatures are thought to have once been humans, cursed and mutated to feel pain at all times except when killing. The rumors persist and attempts to capture a blade stalker and reverse these changes have all met with failure. It is a foregone conclusion that a blade stalker is merely a remorseless death bringer, neither capable nor deserving of mercy.
