| Suggested name | Theus |
| Planet type | Warm planet |
| The carbon dioxide has probably photodissociated, and the free methane has been swept into interplanetary space by the solar wind because of the lack of a planetary magnetic field.
A prominent result is the "great white spot", a giant storm that is known to have existed for centuries since it was first detected by scanner.
The surface is dangerous because of the barbaric stone-age oceanic creatures known as "Dita-pe". They survive scattered in groups by eating the Erdes Dei plant that lives there. Most Dita-pe are not related to the Rihionn but have wings and vary in length from 40 to 60 meters. They are able to reproduce at temperatures from -40 to -10°C and even intense weather. |
