When it comes to the upcoming adaption of Stephen King’s Dark Tower series by horror legend Mike Flanagan, the universe that the horror author has crafted is so vast and has so much lore attached to it that determining what to include in the show’s first season is crucial to the direction that the series will take. Many fans of the books know that the first book begins with the line, “The man in black fled across the desert, and the gunslinger followed.” Yet when his hunt for the man in black first began, he had another adventure that came before the first book’s events, found in the short story The Little Sisters of Eluria.
