The prince of mages

“A legend told that far, far away, in the farthest reaches of the magical kingdoms, there was a city, a great black city built on a mountain famous for its curse. Only the dark mages and all those deeply rooted in darkness had the possibility to penetrate this place of night, feared by all. It was there, unknown to all, that a young boy was imprisoned. He lived only within the walls of a huge building, among other children, and led by a banished mage, who wished to subdue him because of his rebellious and indomitable nature. He did not know how to free himself from this terrible prison. But the opportunity came at his thirteenth birthday when he discovered a power that the black mages wished he never had.”
