Kl'Thurg was a Vech'Klarg commander from planet K'Thal sent to negotiate a peace treaty with planet Earth. The meeting went quite well until he learned that the Earthlings' souls were, unlike the Vech'Klarg's thremklaas, "low-fat". He declared war and within three hours most of the Earthling race was decimated, but three months later he, along with most of his fellow Vech'Klarg, dropped dead of a massive heart attack.
