This is Midnight, the commander of the Umbra Shadow forces. She was kidnapped when she was a caterpillar. The scientists of the tribe that took her used Midnight and her sister as lab rats, her sister never making it out of her cocoon and Midnight's lack of wings are proof of that. However, right before she was going to grow out of her cocoon, her tribe managed to take her back, but they couldn't save her sister. After Midnight realized that she would never have wings, she started using dark magic in an effort to grow her wings back. One night, she was caught doing her dark rituals by a pup named Nova. Her clan banished her, and she swore vengeance on them.
