Redcap

Evil fey who relish in murder and violence, redcaps are small humanoid creatures with ruddy brown skin and a taste for blood. They usually wear little in the way of clothing, but no matter what are always found sporting a red cap (from which their name is derived). This cap is red from the blood of their victims, in which they soak it after each kill. A magical power keeps the blood on their cap from drying, and this can grant them special powers. Upon death, the bloody cap dries and becomes nothing more than a grizzly token. Although small in stature, redcaps possess unnatural strength, usually wielding weapons that are twice their size. They are driven to kill and are incredibly dangerous. If it isn't possible to outrun them, kill them quickly, or you'll end up as just another stain on their hat.
