Church of Melsaella
When Koncelli children would be born with black hair, they would be sent off to monasteries to train and become Storm's Sons. Storm's Sons were priests/mages who were trained in power over the storms. Children who possessed black hair but lacked magic powers would become monks, who would search and collect other children who may one day be Storm's Sons.
