So...when you said you wanted us to make a rare colored entry....is this too much? lol. Honestly, if its over the top, I'll re color it. However, I was reading over the species info again and the tribal markings combined with dragon blood lead to this concept...and this little character blurb....which isn't needed but explains my thought process.
There is a legend that deep within the forest lives a magnificent white stallion. He was born completely white with red eyes and his incredible control over fire was apparent even as a foal. As he grew older, his powers grew stronger. It is said that he has such a close connection with fire that it started to change his appearance and become part of him. Now black tribal flames cover his legs and his mane and tail are the color of flames. Some say they have become flames. He bears the tribal markings of a great warrior or leader. Some doubt his existence at all, but every time a foal is born with the power to control flames there is talk of him again, and his legend lives on...
