Asturias & Nuberu
The Nuberu (Asturian and Cantabrian), Nubero (Castilian) or Nubeiro (Galician) -literally "The Clouder"- is a character of Asturian, Cantabrian, Galician and northern Castilian mythology. According to Asturian mythology, the Nuberu (also known in Western Asturias as Reñubeiru or Xuan Cabritu), is the divinity of clouds and storms.
In Asturias, he is usually thought of as a single magical entity that receives various names. A long time ago the Nuberu came to Asturias riding a cloud, but he was very unlucky and fell to the ground: then he asked for shelter but nobody wanted to help him until, late at night, a peasant took pity on him. In appreciation for his help, Nuberu irrigated his fields, and gave him good harvests, and has continued to provide rain to the people of the region. The story tells that some years later this peasant had to make a long journey to Egypt, and when he arrived in that land he heard that his wife was about to marry another man, thinking that her husband, after so many years of absence, already had died. The peasant then asked Nuberu for help and together they travel back to Asturias riding the clouds and they arrive in time to prevent the wedding. In Asturian villages it is common to ring the bells in order to exorcize Nuberu.
