Transformers Prime: Sparkless

It is said that the Spark is what defines a Cybertronian and that the past has a way of creeping into the present. Primus works in strange ways, and when two bots, who many thought died, return; the revival of Cybertron hasn't been more clear. {Contains OCs, that change the overall story, while also going with the original plot-line of TFP, minor to major changes to the plot.}
