This won't affect the main characters; I've already worked out who they are, how they'd react, and what bits of their background would let them react the way they have. This is more for side bits on how random background characters are inclined to react, or comments on how the population as a whole is dealing with the situation.
Location: Worldwide, with a focus on first-world countries.
The situation is this: One day, about 20% of the world's population changed into something . . . different. Vampires, shapeshifters, were-mermaids, weredragons, werewolves, fae, witches and wizards, etc. This doesn't affect their minds -- they all still think the way they did before, they're still the same people, the only difference being that they now drink blood or can turn into something at will.
