High Quality Content by WIKIPEDIA articles! Randall Flagg is a fictional character created by Stephen King. Flagg has appeared in seven novels by King, sometimes as the main antagonist and others in a brief cameo. He often appears under different names; most are abbreviated by the initials R.F. There are exceptions to this rule; in The Dark Tower series, the name most often associated with Flagg is Walter o`Dim. Flagg is described as "an accomplished sorcerer and a devoted servant of the Outer Dark" with general supernatural abilities involving necromancy, prophecy, and unnatural influence over predatory animal and human behavior. His goals typically center on bringing down civilizations, usually through spreading destruction and sowing conflict.
