Carmina is considered a pioneer, creating new directions in the art of pyromancy. She was able to harness the power of the pyromancy flame in order to actualize the inner self. This is, to applicate the flame to one's own self, granting new powers and abilities. She's known to have created three pyromancies: Flash Sweat, Iron Flesh, and Power Within.
The name 'Carmina', from the hebrew Karmel and mostly proper of hispanic cultures, seems to reference the color Carmine, a deep and dark red pigment.
