Trying to still determine the Dragon girls colors.
By the way, she's wearing something called "Soul Armor", which is similar to "Soul Weapons" in that they are made/forged using the essence of the person like their hair/stats/etc. She used to be covered in scales all over, so she sacrificed that to make highly durable, self-repairing, scaled cloth and now has smooth skin.
By the way, the knight dudes skin is suppose to be reflective like his armor, since he is a Metalloid, aka a Bio-metal living organism.
As I have it written, he is from the "Bronze" race, which is considered the lowest class.(Although an alternate version has Aluminum as the lowest, lol). Silver, Gold, and Platinum are the races of the higher class. He's trying to overcome his class disadvantage and prove that the shimmer of his skin doesn't define him. :psyduck
The guy in the above post is of the "Silver" race of Mettaloids(although I might call them Metallions instead), and although he had an averagely promising future, when they did the element test on him, and found him to have the "Dark" element, the town tried to destroy him, but he managed to escape to the the Dark side of the planet.
Oh yeah, I should mention, this story takes place on a world that has one side perpetually in night time, and the other side always in day time. Obviously, all the lower class people are forced to the dark side, while the rich and higher class people stay on the day side.
