Kar'lo'theuses
From Harthorns-Reverie
The planet in which Quaiskopribra is found.
Sky
The sky is made up of a unique type of gas that absorbs and holds radiation, including light, slowly emitting it, creating the sun and stars for Kar'lo'theuses. The less radiation is holds the less it weighs, causing it to slowly rise through the water, as it gets closer to the surface, the more radiation it absorbs, causing it to sink back to the bottom, only emitting the radiation once it's out of the Sea, giving the sky light.
