I’m a bit of an Howard Philips Lovecraft fan, perhaps obsessively so, so you can no doubt see the obvious chthonic origins of the Nine Screaming Men.  If you have never read Lovecraft’s work, my current favorite story of his is “At the Mountains of Madness,” available online for free or in many different reprint collections at your local bookstore.  Well, at least while bookstores are still around.
