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.
