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.
He has black hair and dark deltas under his eyes.
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.
