Randall Flagg has been written by Jamey Sheridan.
 He first wrote a poem, "The Dark Man", about a man who rides the rails and confesses to murder and rape; written on the back of a placemat in a college restaurant, the one-page poem was published in 1969, but the character never left King's mind
 Here Flagg is depicted as the Covenant Man: central villain of the book's story within a story, "The Wind Through the Keyhole", a legend from Mid-World set years before the series' beginning
