90:2.6

Though of ancient origin, the rain makers, or weather shamans, have persisted right on down through the ages. A severe drought meant death to the early agriculturists; weather control was the object of much ancient magic. Civilized man still makes the weather the common topic of conversation. The olden peoples all believed in the power of the shaman as a rain maker, but it was customary to kill him when he failed, unless he could offer a plausible excuse to account for the failure.
