In the other direction, the plain was open and mostly flat, except for some low mounds closer to the high metal shields around the base of the terraforming engines. Those mounds looked human-made, but were so close to the shield that they were probably only artifacts from the initial construction. It would be stupid to build a habitat so close to the engines. I’m not even sure putting one here under a roof that looked like a landing pad was a great idea. Any Pre–Corporation Rim structure that had already been here, buried or not, this close to the build site would have been discovered by Adamantine during the initial engine installation. Not that they would put it on the survey or anything.
