Płanetnik
Płanetnik (also chmurnik, obłocznik) is a Polish demonic cloud spirit — the soul of a suicide or sudden-death victim who controls storms and hail. Appears as a tall old man in a wide hat or a small creature. Can be benevolent (warning of storms) or malevolent. Gains favor by throwing flour into wind or fire. Fights storm-dragons in the clouds. Also a term for weather-divining shamans.
