The Seed (World)

Okay, since I don't really understand the "Submit World" feature I'll use the character feature instead because I wanted to write a thing or two about the world I'm currently working on. 

The world my characters live in is a modern/futuristic, solarpunk aesthetics world with a mix of technology, supernatural powers and a sprinkle of magic.
The celestial body, called The Seed or Small Sibling is one out of three moons orbiting a large planet (usually called Great Sibling) that is fairly close to the sun. While the planet itself is too close and therefore too hot to host life it's reflected light provides the perfect amount of light to allow life to dwell on The Seed. However, just like our earthly moon, the rotation of both bodies causes only one side to ever face the Great Sibling, wich is why it's backside is completely unprotected from the sun, causing it to be uninhabitable as well.
Since the Moon only recieves reflected light there are never really bright days. If you'd stand on it's surface and look up to the sky you'd see a giant planet in it and, depening on the time, the other two moons.
