From the Demon Accords books, Vampire Virus (V2 or V Squared) confers biological immortality & Lycan Virus (LV) extends life up to 300 years or so. The Picture Of Dorian Grey is a novel written by Oscar Wilde published in 1890, about a guy who makes a wish for long life in exchange for his soul. The wish is granted by parties unknown, but probably not angelic. His picture ages, while he stays young & has a great time. It doesn’t end well. There were several movies made about the story & he was featured in The League Of Extraordinary Gentlemen movie.
Since Mr. Conroe probably hasn’t sold his soul & hasn’t been infected with the viruses, we won’t be reading about Chris’s immortal adventures forever, just while Mr. Conroe is extant.
