Lovecraftian Vegas
Pete at A Perfectly Cromulent Blog describes Las Vegas thus:
I mean, I always assumed Vegas (the Strip, especially) was this massive networked series of gaming and security systems, all run by some vaguely Yog-Sothothian being housed in a giant cave under Nellis Air Force Base. I just wasn't expecting it to be confirmed so conclusively.
Love the Lovecraftian vibe. Glad he made it back safely.
