Professor H.P. Hatecraft is a novelist and a teacher at Darrow University. He has a large fan following for his horror books featuring the fictional character "Char Gar Gothakon", such as The Shrieking Madness of Char Gar Gothakon: The Beast That Hath No Name.
Professor Hatecraft is a tall and slender Caucasian male with black hair, a black goatee, and dark deltas under his eyes. He has pale skin, as if he is rarely outside in the sunlight. He wears a black suit with high collared white shirt, a black necktie, and black shoes. In attempt to appear trendy while writing a teen vampire novel, he switched from a more traditional hairstyle to a side shave.
Hatecraft has rather depressed mannerisms as if to suggest he has actually seen some of the horrors he has written about in his books. He is something of a bibliophile which is not unusual for a professor of English and a writer.
