Death Trance

A Death Trance is a trance that only children of Hades (and possibly also Pluto) can enter. The person must eat one of Persephone's pomegranate seeds in order to enter the Trance. One seed is equal to one day, during which a person who entered the Trance lies in a deathlike hibernation, consumes no oxygen and becomes very weak. It is unknown whether or not the user ages during the trance.
