Celestials have a much wider range of colorization than humans - but not obscure at all. They range from the extremely fair, to the extremely dark. Each has their own Domain, which influences their appearance. For example, Khalindra is the Stars - her golden and silver appearance reflects this. One with the domain of Sun may be bronze toned with bright hair and eyes, while one of the domain Night may have black flesh (As in gray/black, not African American) with dark colored hair.
However, I must note that the Celestials are born from Humans, and while they may be able to have skin in the darker tones, they are not able to have a color palette of say...blue and pink skin or hair. It's just not possible.
This race has the highest threshold of Tiya, and are the seers, profits, sorcerers and magicians in Svatura. Of course, skill level ranges from absolutely zero to amazing, but on a scale from one to ten the average magic user will be in the 3-4 range.
Children born are considered adults (or "coming of Age") when they first begin to show their magical abilities and what talent they will have. This usually happens around twelve or thirteen, though it can happen much later in life.
The wagons are pulled by Alicorns - One black, one white, representing Night and Day. Each have wings representing daylight and evening, and each have horns - one, obsidian with the night sky encased and the other a startling pearl with a rainbow sheen.
When a Celestial feels it's their time to die, it is said that they choose a human of psychic tendency to take their place amongst the Caravan so their knowledge never dies. This human may not even show or be aware they have the dormant ability, and will only become aware of it once the Celestial has passed on their memories and knowledge. This usually happens by Dream-walking.
