Hubin listed title with strong sci-fi overtones in which an Oriental cadre of secret masters aspire to immortality through imbibing an elixir of unknown provenance, and by using advanced technology to preserve themselves. They threaten the world, but are defeated in the end (Blieler p61, the only title by this author listed).
