Wow. This is really awesome and interesting. I love how Snape is constantly looking for danger and plots everywhere - war will do that, especially when you're a double agent. I love the details about the pure-blood elites and hw the whole Blood thing works and that the elite are almost like a race in themselves (pale, fair, blonde etc). ALSO the backstory you've created for Snape is so interesting and unique - I don't think I've ever seen this sort of take on his history. But it makes a lot of sense too. I just love how thought out this whole thing is :)
