Black Dragons are warriors. They are strong and capable in battles of force, but also ample magic users, capable of devastating opponents with their spells. Their bright eyes give them excellent night vision, which is why they generally hunt during the night.
Darkwing was always characterized by his confidence. He was ever startled when he could not win a fight or when his wit was not as quick as another's, but that never fazed him. He knew his worth and even felt a little better than that, and it made him an excellent support for his shy, self-conscious mate; whenever she was down, it surprised him that someone as beautiful as her, as perfect in his mind, could feel anything but amazing about herself, and his enthusiasm was catching.
Then the War broke out. Suddenly he was outsped and outmatched by those he once would have called his friends; suddenly he and his family were thrust from the fertile central territory, banished to the barren lands where they now reside. All his strength, his wit, all that he knew was there even if it didn't always turn up... All of that was gone. None of it helped him. And now he's only left to wonder if he ever had them at all. It's all he can do to be a supportive mate and father. He's lost his self-faith.
