ブライアン・ラムレイ
Brian Lumley expanded on the character of Baron Ferenczy, mentioned but never met in "The Case of Charles Dexter Ward", in his "Necroscope" series, specifically "Book IV: Deadspeak", where Janos Ferenczy uses the Yog-Sothoth formula to call forth whole bodies from ash remains, and to return them to that state.
