Sect of Maadmug
The Sect of Maadmug, less commonly known as Maadmugism, is a major religion in the Settled Systems.
Central to their worship is the world saviour Maadmug, who is considered by followers to be the first among mortals to decipher the nature of the Cosmic Principle.
The Cosmic Principle is a belief that the universe is in a cycle of birth and death, caused by the 'breathing' of a Cosmic Anima, an ineffable entity of unimaginable scale. A universe is born with every inhale of breath, and dies with every exhale.
