Fictional info (?)
Suggested nameDwei'der
Planet typeCold planet
It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 75°K (-198°C), and has a complex, layered cloud structure with oxygen thought to make up the lowest clouds, and carbon dioxide the uppermost layer of clouds. It is named after the deity Dwei'der, the bringer of fear.

It may have had water oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect.

A prominent result is the "great white spot", a giant storm that is known to have existed for centuries since it was first observed by radar.

In 2780, images from Wayfinder 8 showed Dwei'der as an almost featureless planet in visible light, without the cloud bands or storms associated with the other cold planets.

The harsh lakes are mostly full of friendly but shy and stone-age oceanic creatures known as "Esyash". They survive while seeking the Yingp. Most Esyash are somewhat related to Engjyazh Yech but have 5 eyes and vary in size from 17 to 41 mm. Most Esyash are known to survive temperatures from 10 to 30°C and sometimes severe infection which is common on Dwei'der.
