While this drama is set in the time period of Solomon Kane, it is reflected against a hidden, secret backdrop of grand science fiction. The closest analogy I can think of would be The Matrix visiting Star Wars while stopping by Westworld's flat. I don't want to give away anymore than that, besides this being a rationalized world with a strong central theme.
