With the All Spark gone, we cannot return life to our planet. And fate has yielded its reward: a new world to call home. We live among its people now, hiding in plain sight, but watching over them in secret, waiting, protecting. I have witnessed their capacity for courage, and though we are worlds apart, like us, there's more to them than meets the eye. I am Optimus Prime and I send this message to any surviving Autobots taking refuge among the stars. We are here. We are waiting.Transformers, by Optimus Prime
Before time began, there was the Cube. We know not where it comes from, only that it hold the power to create worlds and fill them with life. That is how our race was born. For a time we lived in harmony, but like all great power, some wanted it for good, others for evil. And so began the war. A war that ravaged our planet until it was consumed by death, and the Cube was lost to the far reaches of space. We scattered across the galaxy, hoping to find and rebuild our home. Searching every star, every world. And just when all hope seemed lost, message of a new discovery drew us to an unknown planet called... Earth. But we were already too late.Transformers, by Optimus Prime
