Defensive Flight is a half breed between a dragon and a pony in his words "just don't ask" and yet lost his family when his brother went mad and destroyed his home along with himself and their parents.
Luckily as a child Defensive found a home with the Coglinks after befriending their youngest son Axton who moved out not too long after for special reasons. Unfortunately defensive still hasn't earned his cutie mark even into his adolescents and he is becoming more and more haunted by his past. Will it catch up to him and will he ever earn his mark finally.
