Revenants

You may not believe that Revenants are real, but I assure you they are. Along my travels I came across one of their kind, who was willing enough to answer some of my questions about what they are. Revenants died, they can come from almost any other species, but at some point after death, they change into the Revenant form, which stands between 5 ½ to 6 ft in height with black to pale white skin, completely red eyes and white hair. When a Revenant is hurt, they do not bleed, and their wounds do not heal or scar, instead they are forced to sow, staple, or patch over their damage. Keeping themselves whole. What is worse, they are haunted by murderous thoughts, constantly trying to pull them into a mental darkness. Those that give into these thoughts eventually either end themselves or simply disappear. Revenants are rare, and most are not as helpful as the one I spoke with.
