Manichaeism is a major Gnostic religion that was founded by the prophet Mani (c. 216–276 AD) in the Sassanid Empire. While most of Mani's original writings have been lost, numerous translations and fragmentary texts have survived. Manichaeism taught an elaborate dualistic cosmology describing the struggle between a good, spiritual world of light, and an evil, material world of darkness. Through an ongoing process which takes place in human history, light is gradually removed from the world of matter and returned to the world of light whence it came. Its beliefs were based on local Mesopotamian gnostic and religious movements.

It has no formal head and no special game mechanics.
