|I don't see any Inca there. Do you?|
The second document adds only a little more than what was in the preview, stressing that the Cthulian vampires are different (but the same) and that they are waiting for the stars to become ri..."The Arrival." So we have monsters from beyond time and space, poised to drive mankind to the brink of madness and bring about our destruction, who are pretty much identical to the vampires and other creatures except for "small twists that make them unique".
It really seems more of a mild makeover than anything setting-shattering. The setup is going to be rife with internal inconsistencies and disconnects as a result of having "things man was not meant to know and the universe hates you" alongside a pastiche of Judeo-Christian like concepts such as demons, angels, God, etc. It's just plain poorly thought out. It essentially treats the Mythos like something you can just add to whatever to try to make it better. Kind of like sriracha. Everything is better with sriracha, right?
