Black mages are a race of man-sized dolls made by Queen Brahne. The same name of the race is also a class.
The Black mages were created by Mist to be soulless magical allies to their master. They were created similar to the Genomes as being artifically produced life organism. Kuja teaches Queen Brahne how to manufacture them due to his knowledge on the Genomes creation. Black mages are created differently, as they are created by the elements of Gaian. They are produced in a secret factory beneath a village called Dali. They are first produced as a type of egg. They are then shipped to a woman named Alexandria on a cargo ship.
