Well, not so much perfection as elitism. There's a strong theme leaning towards the "elites/gods" vs the "dogs/mortals" mentality. IE, the "I'm better than you" mentality, and why it's self destructive. Now obviously that's not the whole theme as there's plenty of other elements in there, but that is part of what initially starts the war, and then later drives it to its climax. And yes, I did sorta feel that "vampire" touch to it, but thankfully nobody will get their blood sucked out in the process. lol.
As for 3 books, yeah, your idea does sound like a viable idea for the concept I have. What I'd likely have to do first is write the entire thing from to back, then decide if it needs to be broken out into multiple books. That's how I've ended up with a couple of the trilogies I have floating in my work pile. IE, at 250k it was too big for one book, so it got sliced into 3. But with the entire thing written, it makes the breaks between the three books easier.
I also avoid one of the common failings I have with writing is the inability to tell exactly how far a story will go. I can guess, but ultimately I don't know. For example, my recent book "Offworld Chronicles" was supposed to be 7 books when I started, then it stretched to a projected total of 12, then down to 3 as the story matured, and finally ended up just being one once I started polishing and realizing how much fluff and dead weight I had in the book. So yeah, that's one reason why I prefer to write the entire series front to back as one massive story before committing to breaking it up into specific books.
