Fiendish pests that infest derelict wizards&#8216; towers and laboratories, the kalkes are either the by-product of botched gates into the lower realms or the personification of an evil deity's contempt for wizards. All kalkes act with the arrogance of magi while having the social characteristics of baboons. Being of fiendish blood, kalkes do not age and require neither food nor drink. Though lacking any formal spellcasting ability, all kalkes can produce magical effects through the dramatic mumming of largely spontaneous and unstudied rituals.
