At some point, everyone has to fight. Some fight with words, writings, but most of the dragons fight with brute force. And it's what she did on the arena, before she become well known in military ranks. Train, fight, train, fight - that was everything she was doing before joining military. Being a champion of the arena, made that only easier to advance in ranks. Most tribes was afraid of her, knowing that she will fight to the end, taking as much of her enemies with her as possible before giving up. She was the most agile and fastest dragon back there, outspeeding everyone in the air and battlefield.

I'm slowly getting her entire story written in my head and writing it idea by idea on the paper. I can say, my imagination is really, really turned on the highest level as possible. Even if I don't write too much, more art will reveal it.
Thanks to~dragonsica for this piece of art that reveals her ferocious part of her life. https://www.furaffinity.net/user/dragonsica/
