Final Fantasy Magi
The Centra are known to be those who caused The War of the Magi by enslaving the entirety of the races of men and subjugating them under their magical powers. A technologically advanced race of magic-using ubermensch, the Centra were defeated in the War by the Seven Ancient Heroes, a group of misfits from around the world who banded together to free mankind. All Centra have been wiped out since; not a single one is known to exist in the world.
The Centra’s technology is often marked by extensive use of silver metals, computer monitors, computer control and enormous, expansive underground cities.
