If the planet has no atmosphere, its climate is instead extreme, based on the Zone it inhabits. Inner Cauldron airless planets are Burning Worlds, Outer Reaches Ice Worlds. Airless worlds in the Primary Biosphere can be either, either decided at random (use 1d2) or based on which other Zone their orbit is nearer to. Roll on the Water and Life table next, using the column corresponding to the planet's type. If the world is Burning or Ice-bound and a result indicates it bears extremophile life forms, the world bears 'Trapped Water' as described in that result, and additionally you may choose to ignore the life rolled and treat it as a pure Trapped Water result. You may optionally roll even if the world has no atmosphere or a toxic atmosphere, in which case it may bear extremophile organisms which do not make use of water in their biology.

Regardless of whether the world bears life or water, next roll for the distribution of its land.
