Hi OP, the whole bloodline thing in time is their own Achilles heel. The genetics get corrupted among aristocratic families. Ibn Batuta explored more before Columbus and observed this and seen that Aristocratic families go extinct within 150 years. Nietzsche later observed that the families go extinct and the poor carry healthy genes and basically rise to the top filling the void to bring in healthy genes to work against the corrupted genes.
So in the end the homeless and the poor are the memory banks of genetics that basically cleanses the corrupted genetics. Anthropologists argue if a comet strikes wiping civilization away, it is the homeless best able to survive and carry our genes and traditions. Bloodlines are really a genetic cult that overlooks their hubris and damage to their genes.
