In human terms, Lynni is a chimera. She carries two strands of DNA in her body. She is unaware of what this means until she joins her sister at the Lunar Base and goes in for enhancement into the species of one of her ancestors.

Her genes are split down the centre, and since the techs weren't aware of them, her enhancement goes wrong.

Leko is the Familiar assigned to Lynni, and he spots the problems in her transformation before the medics notice, saving her life. His duty is to watch her and keep her healthy and safe. He feels that she is calm, quiet and ladylike. He believes it until she is out of medical and able to voice her opinion.

Once she starts, she doesn't stop.
