Sorcerer Kantobar is a prime example of Sorcery at it's most stable. That is not saying much. In this particular scene, Kantobar is a special guest Sorcerer for Magus Serling Tenthorn, to explain to acolytes what it means to be a sorcerer. He is a tad arrogant, wreathed in gravitas, at least until he slides into a surprisingly casual tone. he's quite nonchalant when it comes to talking shop about his craft. but when he is crossed, he goes full megalomaniac as he channels impossibly strong magics.
This is a very clean slate of a character, you have an idea for a supervillain or someone evil sounding, by all means. have fun with it!
