To the northwest of the terraforming engines’ mound, a couple of kilometers out of the danger zone, was a section of ground, dust-covered but clearly too flat to be natural. Dirt had drifted up to disguise the edges, but what was visible indicated an octagonal shape. Also, it was about the right size for a couple of the colony aircraft to land and sit next to each other without pushing safety requirements. (The main colony had three left of the original set of air vehicles, and a few built-from-scratch models. The originals looked like early, half-assed versions of the company’s hoppers, with scratched and fading paint in the Adamantine brand colors. I could see why there wouldn’t be a lot of visiting back and forth, even if the two groups had been friendly; I wouldn’t have wanted to fly across a planet in one of those things, either.)
