The Black Huntsman of the Wolf's Glen. Samiel was an evil spirit who entered into compact with a marksman. He gave the marksman seven charmed balls, six of these were to hit unerringly whatever was aimed at, but the seventh was meant to deceive and to be directed as the spirit wished. See Freischütz.
