The final issue of the Defiance comic, a prequel to the new movie – bridging the gap between the two, has hit American news stands. The issue goes into some depth about the origins of The Fallen, the power of the AllSpark, how to restore that power and the first cybertronians created using the AllSpark.

As summarised by Seibertron:

The Fallen and his “brothers” were born on a terrestrial world where the Allspark was located. They learned that the energies of the Allspark were limited, and could only be restored through the destruction of a sun. In order to help them, the Allspark created workers who would go out and search for suns that would help to fuel the Allspark. These workers were the first Cybertronians. (Among which is Jetfire.)

The Fallen decides he wants the power of the Allspark for himself, but was trapped in his sarcophagus (the ancient relic discovered by the Transformers in Defiance #1), where he is to remain until the sun harvester is located and reactivated once more.
