Backstory: Sparky was born in a dragon's cave. His mother was a dark dragon, and his father a horse. His father left a while after his hatching, leaving both Sparky and his mother alone in the war. One day, the light dragons had found there way near his cave. Sparky's mother had no choice but to hide him with the Crossbreeds- and went to fight. Later the dragonhorse forgot about his parents, and lived with the crossbreeds his entire life. He was trusted enough, and was granted leadership. A few years after, he met Tealwing, a lone mare. He took care of her, and sort of adopted her as a sister. All he wants is peace.
