There exists a brutal myth that all dungeon masters were evil, sadistic men who delighted in the pain and torture of others. Despite his appearance, Kothar Akshapsut is not thay kind of man. He does his job, inflicting pain on others to extract information, or to punish them for transgressions against the crown not for his pleasure, but because it is his job.
Selected for his size, Kothar was put in charge of the Pharoh's dungeon, and he adapted to his new duty. By day, he would put whip to the backs of criminals, or carry out other tasks, but when night fell, the jackal would remove his mask and go home to his wife and kids. Really, think about it a moment, is that too hard of an idea to picture?
