Cybertron... four million years before the Transformers came to Earth. As civil war rocks the Transformers' home world, Optimus Prime faces his first - and greatest - challenge. But before he can deal with the Decepticons, the new Autobot leader must look within... and decide if Cybertron is worth saving at all! IDW is proud to present an all-new collection of this long-out-of-print tale from the Transformers' past.
