The ships of the Lunarian Sphere were curious things, really.
At a glance, they'd appear primitive, almost falling apart; exposed girders, reinforcing struts, a jumble of antennae and sensor dishes, the inner workings and guts of their operation peeking out from behind massive, geometric slabs of hull plating. But look closer, and you'd find... oddities. Complex computational power, highly efficient engines, things that seemed beyond the technology of the rest of the craft.
If you were to ask about these components, you'd get odd looks.
"How do they work?" you might ask. Well, obviously nobody really knew, not properly.
"But if you don't know how they work, how do you build them?" would be your likely reply. As if explaining to a child, the Lunarian would explain that its just one of those things.
"One of what things?" comes your inevitable, irritated demand. And at that the Lunarian would simply shake their head, waggle their antennae, and give up; perhaps if they liked you, they might compare it to how you always know how to patch yourself up when badly injured, or how to write, or speak, or navigate by the stars. Building those components, you see, is simply one of those skills that nobody has until they need it.
Whether they really understood them or not, those mysterious components certainly worked, and it was thanks to them that the Lunarians had managed to reach as far as they had across the void of space. And as one such ship sat slowly drifting through the celestial sphere of an alien star, there were whispers at the wonder of it all.
