The Dream Eater is a creature of incalculable power that is said to be released only at the end of all time. A creature capable of wiping all beings from the four realms of power, both good and evil, Highborn and Falsebloods. The Dream Eater doesn't understand concepts such as good of evil. It only knows to protect human kind no matter what. Even if that means destroying the all creatures from the four realms. It's used as a fairy tale to scare children.
