First Shelter
Set up the basecamp module on a flat expanse of engineered grassland. The soil here is exactly 3 meters deep -- beneath it, the hull material of the ring itself, smooth and warm to the touch. The grass is real, or close enough. It smells like summer in a place that has never had seasons. The shelter walls locked together without issue. We have power, water recycling, and a view that no human should have: the land curving upward on both sides until it disappears into atmospheric haze.
