"A Sword Called Stormbringer!" and "The Green Empress of Melniboné" are the two parts of a Conan story written by Roy Thomas from an outline by Michael Moorcock and James Cawthorn and first published in issues #14 and #15 of Conan the Barbarian (1972). The stories feature Moorcock's "anti-Conan" Elric of Melniboné.
