Genesis

Ruins excavator
Looter

A good dragon, she is not.
Genesis makes a living off of exploring old ruins and selling the spoils of whatever she can get her claws on. Her best tool for the trade is her ability to summon shadows away from even the darkest of caves, letting her see what is hidden. She also has a very handy set of gemologists glasses to locate rare gems and a handy gust-gatherer to let her perform quick take-offs when angry guards or locals come to arrest her.
She's good at her job.
This means she isn't always home and thus, would not make the best home-maker. Someone probably should have told that to Bramblepelt. He was attracted to her for her beauty and sense of daring in the face of danger. Her total disregard for rules drew him in. By the time he realized it wouldn't work out, he was left with two babies and a disgruntled Genesis telling him to 'deal with it.'

Genesis knew she would not make a good mom and, in a rare moment of selflessness, decided that giving the twins to their dad was the best thing she could do for them. Bramblepelt isn't the most mature dragon but at least he's always home.

She gets along well with all the other plunderers and vagabonds in the lair. Lunafreya and her always have pleasant chats and while she has yet to rope the coatl into any of her schemes, Genesis remembers the tricks she was told.
Being the chosen Charge from her ex isn't ideal but it sure does keep him wrapped around her finger at least. It also keeps her safe from rivals and authorities.
