Unicron slept.
The race of Transformers, though that is not what they were known then, waged tireless war with invaders from a nearby system. As war ravaged their home of Cybertron, the elder council, the Tripredacus, led by the thirteen Primes, foresaw their own extinction. They began the construction of the Arks and a powerful device that could open a bridge through space and time and usher the last of their kind away from their doomed world. And so it was that the greatest of the Arks carried seven of the Primes away from Cybertron and into the depths of the unknown void, in search of another world where they could rebuild. Each of the other six Primes took their own Ark away, each to a different world, all save one who would remain behind on Cybertron, the Sentinel of the Sleeping Primus, the Font of All Sparks.
So it was that Nemesis came, the Herald of the Dark God Unicron, to destroy the greatest of Arks. The Herald struck into the heart of the Ark and became one with the most powerful Prime, Megatron, and twisted it into the Champion of Unicron, Galvatron. Three other Primes were slaughtered as they slept before the Ark became alert and awakened the rest. Optimus, Magnus, Rodimus, these three Primes awakened to meet the Fallen Galvatron and battle him. The three hardly stood a chance. As Rodimus held Galvatron briefly at bay, the other two would sacrifice themselves and combine, forming Omega, who would become the Last Prime. He tore the Dark Spark from Galvatron and hurled him from the Ark and into the void.
But the damage had been done. Rodimus had suffered a fatal wound and the Ark was coming apart. Omega scanned the system and found a planet of mostly liquid surface that would offer the best chances for their crash landing. He set the Ark on course and collected the Primes Sparks into a Matrix that would keep their memories and wisdom safe from the Fall. As the Ark plummeted toward the third planet of the system, it broke into pieces, scattering the Transformers to the corners of the world.
