Half machine, half human. Dreamcatchers are a necessity in the slums of their world, travelling to the uninhabitable parts of the planet to illegally deal in dreams and nightmares - which they bring back to the black market to sell to destitute civilians who cannot afford the Government's dream supply. Highly sought after by Bounty Hunters and Government agents.
Inspired by Blade Runner and Ghost in the Shell. And okay, maybe some Akira too.
