Deimos
Home to dark elves, that run a monarchy. They've successfully been maintaining 1 royal family's power over the moon for centuries. This body has grey foliage and a lively monochromatic ecosystem surrounding its purple glowing rivers. Extremely large mountains and canyons separate regions and provide much needed privacy to its inhabitants. The royal family holds power over a vast palace that encapsulates their world tree, seemingly drawing its spectra from the source. Many think this family is keeping a power to themselves that they use to opress the rest of the population.
