Gaian Type planet in which water covers less than 10% of the surface. High surface temperatures are due to various influences. Precipitation is rare, even at the poles, and desert conditions prevail. The atmosphere will rarely be oxygen-rich, unless there is considerable remnant oxygen in the atmopshere from earlier stages of the planet's evolution.

Life will rarely be advanced in form, but may be highly specialised and hardy.
