The Scavengers

Scavengers do not judge a civilization. They read a planet like a larder.
Every untouched iron seam, every unworked oil field, every fishery nobody fishes is something to take, and they keep a careful inventory. A world that has already started to cook itself is a world that has stopped guarding its stores.
They never come to a planet that has not warmed. After that, the fuller the larder, the likelier the visit.
Work your land, camp your deposits, keep the climate stable — or find out how fast an extraction runs.
