The Cacodemon is a creature viewed as an inferior form of demon. They’re considered the opposite of the Agathodemon or Eudemon. Their name comes from Greek words meaning “bad demon” or “bad spirit,” and it is thought to be related to the Enochian language. They’re thought to be Fallen Angels banished from heaven. Unable to find homes of their own, they live in the space between the earth and the stars. They’re depicted as large and powerfully built humanoids with dark skin, but have been described as swirling black masses. Generally, they are hostile in nature and enjoy exacting revenge and causing harm. They latch onto an individual at birth and follow them throughout life, influencing their impulses and personality. Some believe they act as messengers between their charges and the gods. Some believe they are under the control of Hades and say they have dominion over the twelfth house of the Zodiac.
