Since Lexington and Staghart seem like a couple that would want kids to me, and they live in a universe with pretty good cloning technology, I present their little test-tube hatchlings.

Names and quick intros under cut.

Going left to right, we start with the oldest, Joannah. She's very protective of her siblings and dads, and has the heart of an adventurer. She tries to keep her siblings out of trouble, but often ends up being the one to drag them into trouble instead. What can she say? She can't just deprive them of the thrill. She inherited Staghart’s white fur, blue eyes and antlers, but has a long tail, connected wings and a tendency to walk on all fours like Lexington.

Joshua, the middle child and only boy of the group, became fascinated with science fiction the second his dads showed him an episode of Star Trek. A very quiet and laid-back type, he has Staghart’s height, wings, hooves. He has long white hair and green skin just a shade lighter than Lexington’s. When King Arthur met him as a kid, he was given the moniker of "Green Knight". Though he towers over Lexington, even as a teenager, he's a total daddy's boy and takes every hug Lex offers.

Their youngest is Jayla, an excitable young girl with more energy than she could ever use. She's almost completely covered in feathers with the exception of her face, the result of the gene for Staghart’s feathered wings going a bit wild. Jayla's own wings are the longer feathers that come off her arms. Her tendency to stay on all fours like Lexington and Joannah makes her seem very animalistic, which isn't helped by the fact she likes to use short chirps to get people's attention when talking to them.

Brooklyn actually met Jayla as an adult at some point in his timedance journeys. He assumed she was a harpy. She thought it was hilarious, though made sure not to reveal her identity to him. Many years later for Brooklyn, and he sees a surprisingly familiar face when he's introduced to his youngest niece.
