Basically, it's an interactive promo site that the network created at the beginning of the series, presumably to entice और viewers. It provides a bit of fun for the curious and the प्रशंसक alike. :DD
on that website, there's some infos about the show: आप can read John's diary and about the cretures which दिखाना up in the show, आप can watch the fake IDs या the बंदूकों in the सूँ ढ, ट्रंक :)
