Destrudo
Destrudo describes a psychic energy that arises from the Death Drive (Thanatos). It is basically the mechanism that is involved in the destruction of a living being, essentially returning that living being back to "nothing" in extreme cases. It is implied that the effects of destrudo manifest in a living being's A.T. Field. The term is loosely taken from Freudian Psychology and is an opposing energy to Libido as seen in the Psychographs of Episode 20.
