The Raj was actually discovered months ago by a sleuth on Reddit, who dug into the code of the Delos Destinations website and found a reference to “RajWorld.”
Since the episode aired, the Delos Destinations viral website has been updated with a new page: Discover The Raj.
The latest episode of Westworld, “Virtù e Fortuna,” revealed a new park with a British Colonial India setting, and a new page on the Delos website confirms that this world is called The Raj.
The logo on the Discover The Raj website also glitches at regular intervals – a clear sign that all is not well in the park.
