There's a place where living armor still walks.
It's an old battlefield. A location of a particularly bad memory for some cultures. There are ruined buildings, undetonated bombs, corpses, so many corpses. But what lasted the longest was the power armor. The armor that still walks.
They're old models of power armor. Made way back before the mega corporations started getting cheap with the internal processes of such things. Decades pass and they're still functioning. And they way they were made; they would do anything they need to to make sure they're whoever is inside doesn't die.
They're capable of automatically walking if the user isn't able to walk. And in their automatic walking mode they're capable of running from targets, even attacking hostiles if the user doesn't override such protocols. The only problem with this is that they never bothered to let the armor know when the person inside was dead.
All of the armor that contains dead bodies just keeps walking. With the starships they were meant to come back to long since flown away, they just wander forever, looking for rest and safety that does not exist for them anymore. And because of their automatic defense, if anyone tries to remove the bodies they'll consider it a hostile attempt to disarm, and attack. The governments and corporations involved decided that it wasn't of any use to try.
So the armor walks. Some in perfect condition, others with massive holes, or missing body parts, marking their deaths. And they wander. Locals know not to go anywhere near them. They're about as hostile a threat as local raiders or wildlife, and far less easy to reason with. But you can avoid them. And if you don't go close you'll just see them, walking to nowhere. Useally you'll just catch a glimpse, something moving, not quite human but human shaped, in the distance. Occasionally you'll even see a sign of the body inside, parts of the old armor fallen off, to reveal ancient bones.
There is a place where the dead still walk.
