Day 539: State of Decay Part 2

This story features vampires. Slowly, over the course of this episode, we begin to notice that various tropes of the vampire mythos are appearing, such as a fascination with blood, control over bats, and a general gothic demeanour. It's all reasonably effective stuff, and may send a chill down the spine of some young children. But there's still an interest in making this feel different. The key mystery surrounding this story is not the nature of the vampires, but who created them, given that the vampires were originally humans before being converted by some unknown power. It gives the story a driving force that is able to engage the viewer, and make for a more interesting story as a result.
