The Patterners studied the movements of the stars in an effort to prevent another Great Cataclysm.
The Patterners originated from a group of Cybertronians who, while under the surface of Cybertron attempted to discover the cause of the Great Cataclysm. Under the guidance of their leader Azimuth, they came to logically study the movements of stars. When they emerged onto the surface, they began to carve these patterns onto the surface of the planet itself. Eventually, the markings grew to cover the entire planet.
