Though we may come from different timelines and universes, we all share one thing in common: we're at war or just coming out of it. It's spanned millennia. A civil war that branched out into hundreds of galaxies. Billions of lives lost - not only Cybertronian. Great planets, civilizations, lifeforms, all that - gone; blown to scrap. This is all very general, but you're going to hear a lot about it from the others, I know.
