Planet archetypes

Temperate worlds with near-standard pressure, moderate moisture, and standing water. The kindest draw the lottery offers.

Water-dominated worlds where high seas swallow most of the land. Dense, humid atmospheres favor severe weather.

Hot greenhouse worlds under dense atmospheres, with consistently high moisture.

Arid worlds with brutal day–night swings and no standing water anywhere on the surface.

Cold steppe worlds hovering below freezing, scoured by hard winds under thin-to-standard air.

Deep-frozen worlds under thin air. Abundant moisture — all of it locked into ice.

Near-airless ice shells at cryogenic temperatures, bathed in radiation nothing filters out.

Furnace worlds exposed to superheated winds. Any surface water is long gone.

Molten worlds of active volcanism under severely toxic skies — the rarest and harshest draw in the lottery.

Airless rock. Nothing shields the surface from radiation or the day–night temperature whiplash.
