Wizard Leo

Though a sixth rank wizard, he was stronger than many seventh rank ones because of his darkness eye. In order to cultivate the darkness eye, he had to destroy his own eyes.

"Wizard Leo’s eyes sockets were replaced with a daunting, grayish emptiness. Besides, there was a small bulge of flesh which swelled on his forehead. A blood-red eye like a viper grew right in the middle of this mass of flesh."

He is an impatient man which lead to him not focusing on teaching his students. hahaha
