Once Tarik and ART-drone used an air-blowing excavation tool to clear the surface dust away, we saw this was a large hatch, the size that would accommodate the kind of cargo bots and load haulers that might be used to supply terraforming engines. When I got the control pad open, there was also an Adamantine logo on the inside of the case. So this definitely wasn’t another Pre–Corporation Rim ruin, which I already knew, because the materials and assembly matched what we had seen of the other Adamantine installations, and because all indications said it wasn’t.
