A/N: And the last of the bunch. I hope you enjoyed reading them as much as I enjoyed writing them.


If there was one that that could've been said about the Earth, it always was in motion. Judging by the empty landscape and searing temperatures, nothing moving was left.

Even his tough Cybertronian alloy struggled to deal with the extreme temperature, so no living thing could survive here.

Then again, it had been over two billion years since he set foot on this planet, and much had changed since. Perhaps the dominant species had evolved, or a new species had settled on this planet.

Which also made it over two billion years since he'd been resurrected on this very same planet. Perhaps even this spot, though his records of the landmasses differed from what he'd seen when he made planetfall.

Continental drift, his CPU let him know, one of the few remaining movings of this planet. More terms drifted into his memory, learnt back when he'd been a youngling and discovered organic planets and its peculiarities.

Tidal friction, that's what had doomed this planet. The dominant species of the few peaceful vorns he'd spent here were more fearful of a nuclear winter or global climate change, but what eventually did the planet in, was the natural movement of the seas and the pull of its natural satellite. Through all kinds of important-sounding words and complicated calculations, the core message was: this planet'd been slowed down by its natural satellite enough for the nearby star to vaporize the oceans, rendering this planet uninhabitable.

What became of the humans, no one knew. Perhaps they'd finally completed that space-station where they'd been working on so hard. Or maybe they wiped each other out in a war to rival the Autobot-Decepticon one.

He'd never find out, or perhaps if he ran into some humans in one of his many travels he'd find out what became of them. Though space was mindboggling huge, so the odds on that were not in his favor.

It already was a one-in-a-billion chance that he had found the Earth again. The little blue planet had anchored itself in his memory banks. He didn't know if that was because he was resparked here, or because it had played a significant role in the Autobot-Decepticon war. In any case, the little biological lifeforms had also made an impact on him.

Or at least, their music had. It wasn't often that he came across a culture where the tunes were so moving. No matter the genre, any kind of music held so much emotion, so unlike Cybertronian music that at first he didn't like it at all. It was too overwhelming.

But after he'd made planetfall, died in the Mission City battle and had his Spark re-energized with the Allspark, the melodies grew on him. When he caught himself tapping to the beat one day, he gave up his reluctance and immersed himself in the music.

He still had some of those tunes in his memories, and he played them as he carefully stepped over the dried rock of what had once been the bottom of the ocean. The ground cracked under his clawed feet as he set foot on it, and dust was everywhere.

Unbelievable that this'd once been such a lush planet. He had had good laughs here, a new culture to explore and new friends to make. And when they eventually had to leave to continue their war, it'd been with much Sparkache.

He shouldn't have come back here. This was a dead and dry planet, like so many other rocks in this galaxy. Perhaps if you dug hard enough, you'd come across remains of the humans' existence, but that still wouldn't bring their liaison back, or any of the other humans he had shared his love for music with.

With a sigh, the mech prepared himself for take-off. He may have been resparked here, but that was over two billion years ago. The dust-clouds swirling around him convinced him this planet was no longer alive. It was not in motion.
