In the books
In the Song of Ice and Fire novels Kraznys is one of the senior-most nobles and merchants of Astapor, dwelling in an immense pyramid. He has disdain and contempt for anyone not born of Ghiscari blood and considers his people and heritage to be superior to anyone else's, even that of Valyria (despite Valyria defeating Ghiscar in war five times before finally obliterating it with dragonfire). He is immensely greedy. He employs the Naathi slave Missandei as a translator.
