Kruts

Kruts is a type of disease. Legend has it that Dwarf herdsmen brought down this itching, crepuscular rash from the mountains. Maddening, painful and embarrassing, this sickness tends to gather about the thighs, groin and torso. Transmitted by touch, this highly infectious rash is quite a social stigma. Sometimes associated with goats, and other livestock, folk medicine recommends shaving the afflicted area and painting it with turpentine.
