1. What was the actual situation above ground? Is it basically supposed to be our world and hardly anyone is aware of all this human sacrifice going on all over the place all the time? Or are most people aware of the sacrifices, but there's a certain percentage of the population that's bred to sacrificed and raised in a controlled, fictitious world where they are kept unaware?

2. It seemed like they were implying that someone had deliberately sabotaged the operation from the inside but this was never elaborated upon. Was it actually sabotaged? If so, by whom? I would have liked some explanation.
