Chaos magic is a school of the modern magical tradition which emphasizes the pragmatic use of belief systems and the creation of new and unorthodox methods.
Although there are a few techniques unique to chaos magic (such as some forms of sigil magic), chaos magic is often highly individualistic and borrows liberally from other belief systems, due to chaos magic having a central belief that belief is a tool. Some common sources of inspiration include such diverse areas as science fiction, scientific theories, traditional ceremonial magic, neoshamanism, Eastern philosophy, world religions, and individual experimentation. Despite tremendous individual variation, chaos magicians (or "chaotes") often work with chaotic and humorous paradigms, such as the worship of Hundun from Taoism or Eris from Discordianism. Some chaos magicians also use psychedelic drugs in a practice known as chemognosticism.
