Planning the Cosmic Cube

In the original work, descriptions of the Thirteen Primes of the Transformers were exceedingly vague, and conclusions could only be drawn from countless minor details. After Primordial Lord of Heaven and Unicron explored innumerable parallel universes, Primordial Lord of Heaven fell into slumber, his body forming the planet Cybertron. On this planet, thanks to Primordial Lord of Heaven's power, thirteen powerful mechanical lifeforms were born.
