|Uncommon

|''Typically formed in the cooler regions of a star system these worlds have a small metal core and thick rocky mantle with a crust of very deep ice. Geological activity is common in these worlds because of the large quantities of volatiles in the crust, often creating a thin, sometimes seasonal atmosphere.''

|Uncommon

|''Metal-rich worlds like this have a large metallic core, with plentiful metallic ores even at the surface. In places, especially around areas of past or current volcanism or liquid erosion, some higher metals can be found in their elemental form too. Mining is therefore very efficient, so these worlds are highly valued.''
