A group of people with mutations that allow them to manipulate the minds of others by causing hallucinations that send them into a mental space where they can alter space, time, reality, or use elements of nature to attack as a reality in a lucid dream. This group of people rose to the ruling class and turned other ethnic groups into slaves.
