| Suggested name | Youyyou |
| Planet type | Cold planet |
| It may have had water oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect.
The surface of this brutal planet is dangerous because of the large stone-age dinosaurs called the "Cyao'neig Wei". They feed alone by hunting another species called Zwan Gyangn that lives there. They are believed to be closely similar to the Yinn but with 6 eyes and vary in size from 40 to 80 cm. Most Cyao'neig Wei can live at temperatures from 110 to 150°C and high atmospheric pressure. |
