Cottonwood: Lightless Dawn takes place in the town of Cottonwood, in Colorado. In this world, monsters such as werewolves, vampires, demons, and other creatures are real, and have been unknown to most, until recently. Now, creatures are seen as enemies of the people, and are hunted down and killed, both as a sport, and to set an example.
Monsters are not hunted down regularly by authorities, but mass crowd lynchings targeting monsters do happen. It is only when the authorities are contacted when one is discovered to be one, that they are hunted down, so monsters must keep a low profile in order to survive.
