A region is one of the administrative areas of the map. It groups its Hubs, its City, and its Sources and Factories, and it carries the values that apply to all of them: Security, the cargo tiers its Survey Station has opened, and its regional slots.

The Settlement levels of all Hubs and the City in a region add up to the region's level sum. It sets how many Regional Projects the region can hold:

A Regional Project may stand at any Hub or at the City of the region, and each one only once per region. A slot holds one Project with all its levels; demolishing it frees the slot for the whole region. A region that has more Projects than slots keeps them, but cannot start another until its level sum has grown.

The Radio Menu shows the pool as Region: x/y slots in a Settlement's Projects menu and site card; the Live Map shows it in the Region panel.

A region starts with Tier 1 cargo only. Its Survey Station opens Tier 2 and Tier 3, which decides which Sources and Factories can be found there (see Rumors).
