Scholomance
The Scholomance (Romanian: Șolomanță [ʃoloˈmantsə], Solomonărie [solomonəˈri.e]) was a fabled school of black magic in Romania, especially in the region of Transylvania. Folkloric accounts state that the Devil himself ran it. The school enrolled about ten students to become the Solomonari. Courses taught included the speech of animals and magic spells. The Devil chose one of the graduates to be the Weathermaker and tasked with riding a dragon to control the weather.
The school was underground, and the students remained unexposed to sunlight for the seven years of their study. According to some accounts, the dragon (zmeu or balaur) was kept submerged in a mountaintop lake south of Sibiu.
